Ester Introduction: any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids. Esters derived from carboxylic acids are the most common. An ester is a product of the reaction of an acid (usually organic) and an alcohol. Esters mainly result from the condensation (this is, a reaction that produces water) of a carboxylic acid and an alcohol. The process is called esterification. This reaction can be catalysed by the presence of H+ ions. Sulphuric acid is often used as a catalyst for this reaction.

Ethyl acetate is used as a solvent. Methyl acetate, formed by the reaction between methanol and acetic acid, is a sweet-smelling liquid used in making perfumes, extracts, and lacquers. Esters react with water (hydrolysis) under basic conditions to form an alcohol and an acid. When heated with a hydroxide certain esters decompose to yield soap and glycerin; the process is called saponification. Common fats and oils are mixtures of various esters, such as stearin, palmitin, and linolein, formed from the alcohol glycerol and fatty acids. Many esters have distinctive odors, which has led to their widespread use as artificial flavorings and fragrances.

Palm Methyl Ester
Palm Methyl Ester is a family of material that is used as a base for producing Bio Diesel. Palm Methyl Esters is produced from palm oil and is made through a chemical process called transesterification. The conversion of these oils to methyl esters involves the use of methanol as a raw material and a basic catalyst. As Palm Oil cannot be used directly as a diesel engine fuel because it has a higher viscosity than fuels obtained from petroleum products, it is converted into smaller molecules of methyl esters before it can be used as a diesel fuel. Palm Methyl Ester has a unique carbon chain distribution that is set by the oil and process used. Palm Methyl Ester is a ready diesel substitute and is the greatest potential as an alternative fuel source and have also been successfully tested and used as fuel for power stations and diesel passenger cars.

DMC(2-methacryloyloxyethyltri-methylammonium Chloride)
1 Introduction: DMC is the abbreviation of methacryloyloxyethyltri-methylammonium chloride. It is produced through the Menschutkin reaction between DMAM and chloromethane. Its quality indexes reach the standard of the same kind of products imported fiom Japan, satisfying the processing requirements of homopolymerisation or copolymerization. DMC is a cationic monomer. It can homopolymerize or copolymerize with other monomers to produce cationic polymers, which have very strong polarity and affinity with anion substances, so can be widely used as cationic flocculants. DMC can be used in sewage water removal process in sewage treatment plant as well as in wastewater treatment in coal floatation, printing and dye industries. In addition, DMC can also be used to produce high hydroscopicity resins and oil fields chemicals, etc.
