Procedure

Fraction (b) contains 95% by weight of ethyl ester of 3-methyl-4-oxopentane-1-carboxylic acid and 2% by weight of ethyl ester of 4-oxo-hexane-1-carboxylic acid. 41% of the total amount of ethyl acrylate has been converted. The efficiency in ethyl ester of 3-methyl-4-oxo-pentane-1-carboxylic acid amounts to 56% referred to the quantity of converted methyl ethyl ketone, and to 58% referred to the quantity of converted ethyl acrylate.
