Isomyristic Acid.-The hydroxy-isomyristic ester from the preceding preparation was converted to the unsubstituted acid according to the method used by Noller and Adams for ?z-tridecanoic acid. The crude isomyristic acid was esterified by warming with ethyl alcohol (+H2SO4) and the resulting ester was carefully fractionated. The yield of purified ethyl isomyristate was 45-50% (based on the hydroxy ester); b. p. 140-142°at 5 mm., n2£ 1.4342. Hydrolysis of the ester gave isomyristic acid, which after recrystallization melted at 50-50.5°. This acid showed no depression of the m. p. when mixed with that obtained from 10-keto-isomyristic acid.Reduction of ethyl isomyristate with sodium and alcohol gave isomyristyl alcohol (75-80% yield); b. p. 145-150°at 6 mm., m. p. 10-11°, ¿20 0.8429, »2D°1.4437. This alcohol on warming with a large excess of 48% hydrobromic acid (+H2SO4) gave isomyristyl bromide (80% yield); b. p. 120-122°at 3 mm., ¿4°1.0241, 1.4598.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
