About forty alkenes were prepared by dehydration of the corresponding alcohols in the presence of the ferric sulfate hydrate as catalyst. The yields of these alkenes were from 85% to 97%.
The rate constants of esterification of 2-chloroacetic acid with 6 species of the primary alcohols were determined in the presence of and in the absence of catalyst, the hydrate of ferric sulphate.
