Decanoic acid, mixed diesters with octanoic acid and propylene glycol Consists of mixtures of propane-1,2-diol mono- and diesters of fatty acids occurring in
The major types of 3-MCPD diesters (about 85%) were mixed diesters of palmitic acid with C18 fatty acids (stearic, oleic, linoleic acids). These diesters were followed by 3-MCPD distearate (11%) and 3-MCPD dipalmitate (4%). Generally, very little 3-MCPD existed as the free compound (31 microg kg-1).

The product generally is a mixture of different components. Synthesis of fatty acid-PEG-fatty acid diestersFatty acid diesters were synthesized by transesterification of PEG and fatty acid methyl esters (Malkemus, 1956). Stearic acid diester (CRL 1095) was synthesized from 2 moles of methyl stearate (Sigma) and 1 mole of PEG 900 in a reaction catalyzed by zinc acetate. Herein we described the efficient enzyme catalyzed double esterification of BHMF with saturated long-chain fatty acids using biomass-derived 2-methyl-tetrahydrofuran (2-MTHF) as solvent, providing an efficient synthetic route with >99% overall conversion (BHMF mono- and diesters) and between 89 and 99% conversion into the targeted BHMF diesters. While, the diesters of fatty acids with polyethylene glycol (Mol. wt. 600) are used as emulsifiers in pharmaceuticals, cosmetics and food industry, and as wetting agents in the manufacture of fibers and paints, and also, as plasticizers in plastic industry according to their type and purity degree (13, 14).

Propylene glycol mono- and diesters of fats and fatty acids may be safely used in food, subject to the following prescribed conditions: (a) They are produced from edible fats and/or fatty acids in compliance with § 172.860 and/or oleic acid derived from tall oil fatty acids in compliance with § 172.862.

J. Verne, 20 avenue A. Einstein, 69621 The diesterification of d-psicose (the C-3 epimer of d-fructose) with fatty acid vinyl esters of selected acyl chain lengths (C8, C10, and C12) was successfully carried out using Candida antarctica lipase (Novozym 435) at 45 °C for 24 h to give the 1,6-diacyl-d-psicofuranoses with a high regioselectivity in good yields (83–90%).
