The invention relates to a method for the synthesis of diacids or diesters of the general formula ROOC-(CH2)X-COOR in which n is an integer between 5 and 14, R is either H or an alkyl radical with 1 to 4 carbon atoms, from natural long-chain mono-unsaturated fatty acids or esters including at least 10 adjacent carbon atoms per molecule of the general formula CH3-(CH2)n-CHR1- CH2-CH=CH-(CH2)p

The results indicate that ‘‘ester bond’’ is a desirable chemical structure in carbon chain for better thermal properties and reliability, compared to alkanes, paraffin waxes and polyethylene glycols. For linolenic acid diesters, those with 600 mw PEG were significantly more active than those with 900 or 1,500 mw PEG ( p < 0.05), indicating that the optimal PEG domain was smaller (600 mw). This may reflect the effect of the 3 double bonds in the fatty acid moieties on the HLB of the molecule. REACH Fatty acids, coco, diesters and triesters with trimethylolpropane.

These are carboxylic ester derivatives of a fatty acid. Mono- and diglycerides of fatty acids (E 471) refers to a naturally occurring class of food additive composed of diglycerides and monoglycerides which is used as an emulsifier. These of diglycerides and monoglycerides have no limit for daily intake and are used as a fruit coating agent. Fatty acid esters for use in cosmetic compositions are prepared having the formula CH.sub.3 (CH.sub.2).sub.5 CH(OCOR.sub.1)(CH.sub.2).sub.10 COOR.sub.2 wherein, R 1 is a straight chain hydrocarbon radical having 17 carbon atoms with 1 to 3 double bonds therein; and R 2 is a straight or branched chain hydrocarbon radical having 5 to 22 carbon atoms.

10 maj 2020 — so it can either be 1-3-butanediol or glycerol or a medium chain fatty acid. And also you could have monoesters, so one ester bond, diesters,

Here, we introduce the quantitative analysis of 3-MCPD fatty acid esters in palm oil using LC/MS/MS. Synthetic 3-MCPD-dipalmitoyl ester and 3-MCPD-dioleoyl ester were used as standard samples.

IUPAC Name: Fatty acids, coco, diesters and triesters with trimethylolpropane These and other objects are achieved by a fatty acid diester obtained by: first esterifying a hydroxystearic acid with a long chain unsaturated fatty acid to form an unsaturated esterified fatty acid; then, reacting the unsaturated esterified fatty acid with a long chain fatty alcohol to produce a tri-fatty acid diester. The fatty acid diesters of the present invention have the general formula CH 3 (CH 2) 5 CH(OCOR 1)(CH 2) … Safety evaluation of certain food additives and contaminants prepared by the sixty-eight meeting of the Joint FAO/WHO Expert Committee on Food Additives (JECFA). 1984-12-01 Propylene glycol mono- and diesters of fats and fatty acids belongs to the family of Fatty Acid Esters.

2012-09-01 · Based on the reported advantageous thermal and chemical properties of the high-chain fatty acid esters of higher alcohols, the aim of this paper is to present the possible use of the diesters of high-chain dicarboxylic acids with higher alcohols, such as 1-tetradecanol, as novel organic phase change materials for thermal energy storage. Here, we introduce the quantitative analysis of 3-MCPD fatty acid esters in palm oil using LC/MS/MS. Synthetic 3-MCPD-dipalmitoyl ester and 3-MCPD-dioleoyl ester were used as standard samples. Electrospray ionization (ESI) was used as the ionization method and the 3-MCPD-di-fatty acid esters were detected as NH4 + adduct ions due to the addition of ammonium acetate in the mobile phase.
