The EMEREST/TRYDET Ethoxylated Fatty Acids and Polyethylene Glycol Fatty Acid Esters are nonionic, specialized, mono and diesters of various fatty acids. These products can be prepared by the condensation or addition of ethylene oxide to a fatty acid at the site of its active hydrogen or by esterification of the fatty acid with polyethylene glycol. The chemical composition of the monoester product is represented by the general formula R-C0-(0-CH2CH2)n-OH where "R-CO"... 

Palmitoleic acid is a fatty acid with the following condensed structural formula ... 

One of the compounds in jojoba wax used to make candles consists of an 18-carbon saturated fatty acid and a 22-carbon saturated alcohol. Draw the condensed structural formula for this compound. (18.3)... 

Dissolve from 2 to 5 g of the mixture of fatty and resin acids in 10 to 20 ml of dry methanol and add 5 to 10 ml of a solution of 1 part of concentrated sulphuric acid in 4 parts of methanol. Boil the mixture for two minutes under a reflux condenser. To the liquid add 5 to 10 times its volume of 7 to 10 per cent sodium chloride solution and extract the fatty esters and resin acids with ether. Wash the combined extracts with dilute sodium chloride solution, add ethanol and titrate the mixture with 0-5N ethanolic potash. With a mean acid value of 160 taken for the resin acids, and a correction of 1 5 per cent allowed for fatty acids that have escaped esterification, the percentage of resin acids is obtained by the formula... 

Draw the condensed structural formula for a fatty acid and identify it as saturated or unsaturated. 

Draw the condensed structural formula for the ester in jojoba wax that is formed from arachidic acid, a 20-carbon saturated fatty acid, and 1-docosanol, CH3— (CH2)2i — OH. 

Palmitic acid, the 16-carbon saturated fatty acid, is the most common fatty acid found along with the ionized amino alcohol choline in the sphingomyelin of eggs. Draw the condensed structural formula for this sphingomyelin. 

S.V. 115-135 m.p. 48-52 "C The formula shown above is schematic because the chemical structure is very complex and depends on the degree of condensation of the glycerol and the number, purity and kind of fatty acid. Free fatty acids, polyglycerol and, depending on the kind of manufacture, also mono- and di- glycerides are always present.
