KNO1869 adalah minyak dengan kekentalan rendah untuk tekstil, dibuat dari
bahan dasar mineral kualitas tinggi. Mengandung penghambat karat dan oksidasi dan
memberikan daya emulsi yang sangat baik, mudah dicuci, mengurangi kemungkinan
timbulnya noda. Minyak konvensional setelah pemakaian beberapa jam cenderung
berubah warna menjadi kekuningan terutama bila kena panas dan cahaya,
menyebabkan minyak “knitting” konvensional meninggalkan noda dan dapat merusak

Digunakan pada mesin tekstil terutama bila ada kemungkinan kain/benang terpercik
minyak. Pemakaian termasuk pada peralatan loom wires, hosiery, warp knitting dan
mesin-mesin jahit untuk garment.
KNO 1869 sangat mudah dicuci (larut dengan air) karena kemampuannya beremulsi
dengan air. Dianjurkan dipakai pada jarum (needle), sinker, cam, jack pada mesin-
mesin circular knitting dan hosiery.

Sucrose esters are obtained by esterifying sucrose with edible fatty acids from palm oil. This enables them to be used as emulsifiers in virtually all food products. Sucrose esters are used in many applications including bakery, confectionery, cereals, dairy, ice cream and sauces.

 Sucrose esters of fatty acids, commonly known as sucrose esters, and sucrose oligo esters are a relatively  
 new extension to the line of emulsifiers available for the American food market. Being based on sucrose and
 edible fatty acids, sucrose esters are a unique range of high quality, non-ionic emulsifiers. 
 They are obtained by esterifying one or more of the (primary) hydroxyl groups of the sucrose molecule with 
 methyl fatty acids. By varying the degree of esterification of the sucrose molecule it is possible to obtain 
 emulsifiers with HLB values ranging from 1 up to19 for the high mono-esters.

METHYL SOYATE as a solvents


Methyl soyate, a biobased solvent
made from soybean oil, is an excellent replacment for
petrochemical solvents. It offers numerous advantages
over traditional solvents.

Safety advantages
• High flash point (greater than 360 degrees F)
• Low VOC levels (<50 g/L )
• Non-ozone-depleting chemical (ODC)
• Non-SARA reportable
• Readily biodegradable
• Potential for reduced waste-disposal costs

Performance advantages
• Can be used to formulate many types of products
• Provides effective solvency with a kauri-butanol (KB)
value of 58
• Compatible with other organic solvents

Methyl soyate has a high solvency with a Kauri-butanol (KB) value of 58 and has low toxicity when compared to other common substances. In comparison to most commercial solvents, methyl soyate is safer to handle and store due to its high flashpoint of approximately 360 degrees Fahrenheit and high boiling point of well over 400 degrees Fahrenheit. In addition, the Environmental Protection Agency (EPA) does not list methyl soyate as an ozone-depleting chemical (ODC), hazardous air pollutant or volatile organic compound. Methyl soyate�s slow evaporation time can be seen as a disadvantage, but in certain applications methyl soyate outperforms other traditional solvents when longer settle times are needed.

Beyond being an ingredient in cleaners and strippers to replace chlorinated or petroleum products, methyl soyate could find increased use as a carrier solvent. Solvents used as carriers and diluents in a number of alkyd coatings and adhesives include methyl ethyl ketone peroxide (MEK), toluene and xylene for coatings and methylene chloride (MeCL) and MEK for adhesives.
Methyl soyate is not limited to replacement of regulated industrial cleaning solvents. Due to its eco-friendly nature, methyl soyate can be used to clean up and recover spilled petroleum products from shorelines and streams. In fact, the EPA has listed a methyl soyate biosolvent on the National Contingency Plan product schedule for oil spills. It is also licensed by the state of California as a shoreline cleaner.

Formulated consumer products ranging from hand cleaners to auto-care to personal care products that utilize methyl soyate are already being produced and marketed. Additionally, expanding utilization of methyl-soyate-based co-solvents with ethyl lactate in products such as Vertec Biosolvent�s Vertec Gold solvent, and methyl-soyate-based co-solvents with d-limonene (citrus extract) in products such as CITRUSoy by Bi-O-Kleen Industries, Inc. also show promise. Vertec Gold is used in specialty coatings, inks and cleaners and offers increased versatility and high performance. CITRUSoy solvent, cleaner and degreaser are suitable for removing gum, wax, tar, asphalt, graffiti and more. Other new emerging applications for soy-based-solvent products and processes include bioremediation, paper pulp cleaning and highway paving materials that replace asphalt.

Methyl soyate is proving to be a great alternative to chemical-laden cleaners and solvents. Development and commercialization of biobased products are rapidly expanding because of increased government regulations and market demands for safe, healthy and environmentally-friendly alternatives to terpene or petrochemical based solvents and cleaner/degreasers containing butyls. Opportunities to increase the usage of methyl soyate continue to grow

Sodium methylate as Catalyst for Biodiesel

Sodium methoxide is a chemical compound with the formula CH3ONa. This colourless solid, which is formed by the deprotonation of methanol, is a widely used reagent in industry and the laboratory. It is also a dangerously caustic base.

Preparation and structure
Sodium methoxide is prepared by carefully treating methanol with sodium:

2 Na + 2 CH3OH → 2 CH3ONa + H2

The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol. The solid hydrolyzes in water to give sodium hydroxide, and commercial samples can be contaminated with the hydroxide. The solid and especially solutions absorb carbon dioxide from the air, thus diminishing the effectiveness of the base.

In the solid form, sodium methoxide is polymeric, with a sheet-like arrays of Na+ centers, each bonded to four oxygen centers.

The structure, and hence its basicity, of sodium methoxide in solution depends on the solvent. It is significantly stronger base in DMSO where it is more fully ionized and free of hydrogen bonding.

Organic synthesis
Sodium methoxide is a routine base in organic chemistry, applicable to the synthesis of numerous compounds, ranging from pharmaceuticals to agrichemicals. As a base, it is employed in dehydrohalogenations and various condensations. It is also a nucleophile for the production of methyl ethers.

Industrial applications
Sodium methoxide is used as an initiator of anionic addition polymerization with ethylene oxide, forming a polyether with high molecular weight. Biodiesel is prepared from vegetable oils and animal fats, that is, fatty acid triglycerides, by transesterification with methanol to give fatty acid methyl esters (FAMEs). This transformation is catalyzed by sodium methoxide.

Sodium methoxide is highly caustic, and the hydrolysis gives methanol, which is toxic and volatile.

Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a mineral (inorganic) acid having the chemical formula H3PO4. Orthophosphoric acid molecules can combine with themselves to form a variety of compounds which are also referred to as phosphoric acids, but in a more general way. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound. The prefix ortho is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids. Orthophosphoric acid is a non-toxic acid, which, when pure, is a solid at room temperature and pressure.

The conjugate base of phosphoric acid is the dihydrogen phosphate ion, H2PO−4, which in turn has a conjugate base of hydrogen phosphate, HPO2−4, which has a conjugate base of phosphate, PO3−4.

In addition to being a chemical reagent, phosphoric acid has a wide variety of uses, including as a rust inhibitor, food additive, dental and orthop(a)edic etchant, electrolyte, flux, dispersing agent, industrial etchant, fertilizer feedstock, and component of home cleaning products.

The most common source of phosphoric acid is an 85% aqueous solution; such solutions are colourless, odourless, and non-volatile. The 85% solution is a rather viscous, syrupy liquid, but still pourable. Because it is a concentrated acid, an 85% solution can be corrosive, although nontoxic when diluted. Because of the high percentage of phosphoric acid in this reagent, at least some of the orthophosphoric acid is condensed into polyphosphoric acids. For the sake of labeling and simplicity, the 85% represents H3PO4 as if it were all orthophosphoric acid. Dilute aqueous solutions of phosphoric acid exist in the ortho- form.

Phosphoric acid is used:

> As an external standard for phosphorus-31 Nuclear magnetic resonance (NMR).
> As a buffer agent in biology and chemistry; For example, a buffer for high-performance liquid chromatography.
> As a chemical oxidizing agent for activated carbon production, as used in the Wentworth Process.[12]
> As the electrolyte in phosphoric acid fuel cells. With distilled water (2–3 drops per gallon) as an electrolyte in oxyhydrogen
> As a catalyst in the hydration of alkenes to produce alcohols, predominantly ethanol.
> As an electrolyte in copper electropolishing for burr removal and circuit board planarization.
> As a flux by hobbyists (such as model railroaders) as an aid to soldering.
In compound semiconductor processing, phosphoric acid is a common wet etching agent: for example, in combination with hydrogen
peroxide and water it is used to etch InGaAs selective to InP.[13]
Heated in microfabrication to etch silicon nitride (Si3N4). It is highly selective in etching Si3N4 instead of SiO2, silicon
> As a cleaner by construction trades to remove mineral deposits, cementitious smears, and hard water stains.
> As a chelant in some household cleaners aimed at similar cleaning tasks.
In hydroponics pH solutions to lower the pH of nutrient solutions. While other types of acids can be used, phosphorus is a nutrient
used by plants, especially during flowering, making phosphoric acid particularly desirable.
> As a pH adjuster in cosmetics and skin-care products.[15]
> As a dispersing agent in detergents and leather treatment.
> As an additive to stabilize acidic aqueous solutions within a wanted and specified pH range.
