摘要：
Cyclopropanecarboxamide can be prepared by reaction of a cyclopropanecarboxylic ester with NH.sub.3, in which the ester alcohol has 4-8 C atoms and can be straight-chain or branched and which process is carried out in the presence of catalytic amounts of an alkali metal alcoholate of a monohydric C.sub.1-C.sub.8 alcohol at 60.degree.-200.degree. C. in the absence of a hydrocarbon solvent.
