Expired - Lifetime Application number US538539A Inventor Reuben O Feuge Truman L Ward Original 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. Test for sugar 1978-08-01 · Chemical synthesis of mixed diesters of ethanediol with N-acyl amino acids and fatty acids is described.The synthesis is performed in three steps: (1) preparation of N-acyl amino acids using fatty acid ester of N-hydroxyphthalimide as an acylating agent; (2) partial esterification of ethanediol with N-acyl amino acid, in tetrahydrofuran in presence of thionyl chloride; (3) further 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.

They are odorless or have a characteristic odor. Propylene glycol mono-and diesters of fats and fatty acids | C32H62O4 | CID 6850770 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. 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.

This may reflect the effect of the 3 double bonds in the fatty acid moieties on the HLB of the molecule. Since the long‐chain fatty acid sucrose diesters inevitably produced in the synthesis of monoesters are only slightly soluble in water, no important use can be found for them at the present time except as oilsoluble emulsifying agents.

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.

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.
