Ester synthesis stops at about 85% at which point the reaction equilibrium with the co-produced water has been reached. Further synthesis can be obtained if the produced water is removed. In Table V it is demonstrated that a yield of 98% of the wax ester xi istyliryristate is obtained by esterification of iryristic acid with myristic alcohol under vacuum.

Dissolve 23 -2 g. of redistilled hexanoic acid (re caproic acid), b.p. 204-6-205-5°/760 mm., and 21-6 g. of methyl hydrogen sebacate in 200 ml. of absolute methanol to which 0 13 g. of sodium has been added. Electrolyse at 2 0 amps., whilst maintaining the temperature between 30° and 40°, until the pH is about 8 0 (ca. 6 hours). Neutralise the contents of the electrolysis cell with a little acetic acid and distil off the methyl alcohol on a water bath. Dissolve the residue in 200 ml. of ether, wash with three 50 ml. portions of saturated sodium bicarbonate solution, once with water, dry with anhydrous magnesium sulphate, and distil with the aid of a fractionating column (see under Methyl hydrogen adipate). Collect the re-decane at 60°/10 mm. (3 0 g.), the methyl myristate at 158-160°/ 10 mm. (12 5g.) and dimethyl hexadecane-1 16-dicarboxylate at 215-230°/ 7 mm. (1 -5 g.)... 

About 50% of isopropanol use is to produce acetone. Other important synthetic uses are to produce esters of many acids, such as acetic (isopropyl acetate, solvent for cellulose nitrate), myristic, and oleic acids (used in lipsticks and lubricants). Isopropylpalmitate is used as an emulsifier for cosmetic materials. Isopropyl alcohol is a solvent for alkaloids, essential oils, and cellulose derivatives.

Most of the technically produced a-sulfo fatty esters are prepared from unbranched saturated fatty acid esters that are derived from 8 22 carboxylic acids and Cj-C3 alcohols. In particular the C12 (lauric), C14 (myristic), C16 (palmitic), and C18 (stearic) acids are interesting because the ester sulfonates... 

The oleaginous phases of creams differ composi-tionally from hydrocarbon ointments. Many, but not all, creams are patterned after vanishing cream and contain considerable stearic acid. In lieu of some or all of the stearic acid, creams sometime contain long-chain waxy alcohols (cetyl, Ci6 stearyl, Ci8), long-chain esters (myristates, Ci4 palmitates, Ci6 stearates, Cig), other long-chain acids (palmatic acid), vegetable and animal oils, and assorted other waxes of both animal and mineral origin.

Alternatively, a sequence of pervaporation steps can be used to remove the reaction water (Figure 4.10). The reaction solution is pumped through a first fixed-bed reactor and afterwards a pervaporation module is used to remove the water at 80 °C. The solution is subsequently cooled to 60 °C and passed through a second reactor unit. After the next pervaporation step the water content is lowered to 0.2 wt%. By this process, isopropyl myristate is produced from myristyric acid. This and other esters of isopropyl alcohol are used in soaps, skin creams, lubricants and greases [43],...

The extract produced an inhibition of 5-aRl and 5-aR2 activities in the presence of free fatty (oleic, lauric, linoleic, and myris-tic) acids only. Esterified fatty acids, alcohols, and sterols assayed were inactive. A specificity of the fatty acids in 5-aRl or 5-aR2 inhibition has been found. Palmitic and stearic acids were inactive on the two isoforms. Lauric acid was active on 5-aRl (lC5o= 17 + 3 iig/mL) and5-aR2 (lC5o= 19 + 9 p,g/mL). The inhibitory activity of myristic acid was evaluated on 5-aR2 only and found active on this isoform (IC50 = 4 2 p,g/mL) ° . LSESr markedly inhibited both isozymes (Kj [type 1] = 8.4 nM and 7.2 p,g/mL, respectively Kj [type 2] = 7.4 nM and 4.9 iig/mL, respectively). Results indicated that LSESr displayed non-competitive inhibition of the type 1 isozyme and uncompetitive inhibition of the type 2 isozyme . 

Esters are common components in cosmetics and skin-care products. They can be synthesized from fatty acids and alcohols using either chemical or enzymatic reactions. The chemical reactions are normally catalysed by acid catalysts. Enzymatic synthesis is carried out under milder conditions and therefore it provides products of very high purity. A range of esters such as isopropyl palmitate and isopropyl myristate are now produced industrially using enzymatic synthesis. The reactions are carried out in solvent-free systems using an immobilised lipase as catalyst. In order to get high yields in the reactions, water is removed continuously.
