Versuchsvorschrift

Same as Example 1, but with the use of 1.1 mole of sodium ethylate in the form of a solution of 14.5% by weight in ethanol with a content of 0.62 wt.-% of NaOH, and 200 ml of ethanol containing 0.28 wt.-% of H2O, one mole of allyl chloride is reacted at 1.5 at. and a pH of 10.0. The filtration and distillation yield 94.0 g of crotonic acid ethyl ester (yield 89.5%, 6.9 g of vinyl acetic acid ethyl ester (yield 6.6%) and 0.7 g of β-ethoxybutyric acid ethyl ester (yield 0.5%) for a transformation of 92.4% of the allyl chloride.
