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.
Toxics Screening Level
The initial threshold screening level (ITSL) for dimethyl decanedioate (also called dimethylsebacate) is 0.1 μg/m3 based on annual averaging time.
