Chemical Properties
colourless melt or liquid. Needle-like or plate-like colorless or white
crystals. M.P. 38° C. B.P. 293° C.
Sp.Gr. 0.99 (liquid). Pleasant and mild-ethereal-fruity odor. Fruity-winey, ethereal Apple-like taste, but
very mild.
Uses
Polytetramethylene sebacate was prepared from dimethyl sebacate. Dimethyl sebacate was used in the biosynthesis of oligomeric sebacates as lubricant oils. Dimethyl sebacate was a convenient starting material for cyclization of N-Succinylglycine dimethyl ester.
Application
DMS can be used in the synthesis of decanedihydrazide which can be used as a precursor for isocyanates for the synthesis of thermoplastic polyurethanes. Transesterification of DMS with 2-ethylhexanol can be used to synthesize bis(2-ethylhexyl)sebacate for further use in petroleum based lubricants.
Preparation
By direct estenfication of Sebacic
acid and Methanol, usually under azeotropic
conditions.
Definition
ChEBI: Dimethyl sebacate is a fatty acid methyl ester that is sebacic acid in which both carboxy groups are replaced by methoxycarbonyl groups. It has a role as a plasticiser and a plant metabolite. It is a fatty acid methyl ester and a diester. It is functionally related to a sebacic acid.
General Description
Dimethyl sebacate (DMS) is a plasticizer that can be synthesized by esterification of sebacic acid. It is from vegetable origin since it is processed from castor oil.
