CETYLMALONIC ESTER (Malonic acid, cetyl-f diethyl ester)... [Pg.13]

The residual a-ethoxalyl ester is decarbonylated to cetyl-malonic ester by heating at 160-170° under reduced pressure. A water aspirator is sufficient to facilitate removal of the carbon monoxide formed during the heating. The decarbonylation requires about 1-1,5 hours (Note 7). The cetylmalonic ester which remains as a dark liquid is fractionated under reduced pressure (Note 8). [Pg.14]

This method is based on the general procedure previously described by Floyd and Miller.2 Cetylmalonic ester has also been prepared by condensation of ethyl stearate with ethyl carbonate 8 and by alkylation of sodiomalonic ester with cetyl iodide4 or cetyl bromide.8... [Pg.16]

Cetylmalonic acid, m.p. 115.5-120.5°, is obtained by saponification of the ester and one crystallization from acetone. [Pg.16]
