1312655 Cinnamylidenemalonate esters EASTMAN KODAK CO 23 April 1970 [23 April 1969] 19542/70 Heading C2C [Also in Divisions C3 and G2] Diethyl cinnamylidenemalonate is obtained by condensing cinnamaldehyde with diethyl malonate in the presence of piperidine in methylene chloride as solvent. The product is purified (>99% pure) by stripping off solvent and distilling in vacuo. The corresponding dimethyl ester is made by condensing cinnamaldehyde with dimethyl malonate in the presence of piperidine, quinoline, cinnamic acid and a molecular sieve, in benzene solution. It is obtained in a purity greater than 99% by crystallization from methanol. |
