Expired - Lifetime Application number US538539A Inventor Reuben O Feuge Truman L Ward Original 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. 1998-10-01 · We were thus prompted to use fatty acid chlorides (2a-b), which are much more reactive than the fatty acids themselves, enabling the reaction to be carried out at a lower temperature.

Propylene glycol esters of fatty acids are mixtures of propylene glycol mono- and diesters of saturated and unsaturated fatty acids derived from edible oils and fats. The products are produced either by direct esterification of propylene glycol with fatty acids or by transesterification of propylene glycol …

Diesters of fatty acids

Propylene glycol mono- and diesters of fats and fatty acids belongs to the family of Fatty Acid Esters. These are carboxylic ester derivatives of a fatty acid.

Diesters of fatty acids

In the case of Propylene Glycol Dicocoate, the fatty acids are those derived from coconut oil. In cosmetics and personal care products, these ingredients function as skin conditioning agents - occlusive and emollient, viscosity increasing agents - nonaqueous, and surfactants - emulsifying agents. 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.

Caproates/chemical synthesis; Chemical Phenomena; Chemistry; Chymotrypsin; Esters/chemical synthesis; Fatty Acids/chemical synthesis* Fluoresceins*/blood; Fluoresceins*/urine; Lipase 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) 10 COOR 2 Fatty acids of the alkane diol diesters of vernix caseosa.

Test for fatty acids: Add 1 ml of ethanol to 0.1 g of the sample, dissolve by warming, add 5 ml of dilute sulfuric acid TS, heat in a water bath for 30 min and cool. A yellowish white solid or oil is formed which is soluble in 3 ml of ether and has no odour of isobutyric acid.

In the diester waxes from the hamster, both straight-chain and branched-chain fatty acids of 14 to 20 carbon atoms predominated at position 1 and those of 22 to 26 carbon atoms at position 2. In contrast, the diester waxes of the mouse contained mainly fatty acids of less than 19 carbon atoms, both saturated and monounsaturated, at position 2 and those of greater chain length (20 to 24 carbon atoms) at position 1.

The products are produced either by direct esterification of propylene glycol with fatty acids or by transesterification of propylene glycol with oils or fats. Diglyceride, in this example with a saturated fatty acid residue (highlighted blue) and an unsaturated fatty acid residue (highlighted green). 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 . Oil soluble polyethylene glycol (PEG-1500) diesters of stearic, 12-hydroxystearic, oleic and 12-hydroxy oleic (ricinoleic) acids were prepared by standard condensation reaction procedure. The surface active/emulsifying properties of the products were evaluated by determining interfacial tension and through performance test in making water-in-oil emulsion.

A strong acid is one that is completely dissociated or ionized in an aqueous solution. It is a chemical species with a high capac Find out which individuals should use caution when taking omega-3 fatty acid supplements to lower their triglycerides. Richard N. Fogoros, MD, is a retired professor of medicine and board-certified internal medicine physician and cardiologi In general, fish is a good source of omega-3 fatty acids. But you should choose fish that are high in omega-3s and lower in mercury.
