Epoxide was obtained by the following procedure with 99% yield. Ninty-five per cent hydrogen peroxide (7.2g, 0.2mol) was added dropwise during 1hr to a mixture of 36.4g of butyl oleate (0.1mol), 17.6g of benzene, 6.0g of acetic acid, and 1.9g of 50% sulfuric acid, at temperatures of 5060°C. Immediately after addition of all of the hydrogen peroxide, the reaction mixture was poured into water, and the epoxide was extracted with petroleum ether. The product obtained was colorless, and had a purity of 92.7%. The purity was better than that of the product obtained by use of peroxyacetic acid.
Epoxides of oleic acid and butyl ester of tall oil fatty acid was also obtained by the above mentioned procedure. The latter had a purity of 90.8%, but the former had only 60.4%.
