Description
Dibutyl sebacate (DBS) is an organic colorless liquid chemical, a dibutyl ester of sebacic acid.Its main use is as a plasticizer in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, ethyl cellulose, polyvinyl butyral, polyvinyl chloride, polystyrene, and many synthetic rubbers (especially nitrile rubber and neoprene) and other plastics. It can be used for plastics in use in the food packaging industry, in plastics used for medical devices, and for pharmaceutical applications, e.g. as a plasticizer for film coating of tablets, beads, and granules.[2] It is also used as a lubricant in shaving lotions, and a flavoring additive in non-alcoholic beverages, ice cream, ices, candy, and baked goods. It provides excellent compatibility with a range of plastic materials, superior properties at low temperatures, and good oil resistivity. Its other names include Morflex, Kodaflex, polycizer, Proviplast 1944 and PX 404. Dibutyl sebacate is also used as a desensitizer in Otto fuel II, a torpedo monopropellant.

Uses
A permitted flavoring listed in GB 2760-96. Mainly used in the preparation of grapes, pears and other flavors and fruit flavor solvent. In addition, it is often used as plasticizer for resin and vinyl resin as its better compatibility with nitrocellulose and butyl acetate cellulose. It can also be used as synthesis solvent for organic synthesis, solvents and pigments, pharmaceutical intermediates and polymers compound. Diethyl Sebacate is a flavoring agent that is a liquid, colorless to
pale yellow in appearance with a slight odor. it is insoluble in water
and miscible in alcohol, ether, and other organic solvents. it is
obtained by chemical synthesis. it is also termed ethyl sebacate.
-
Production method
It is derived by esterification of succinic anhydride and ethanol; It can also be obtained through heating esterification of sebacic acid and ethanol in the presence of concentrated sulfuric acid.
