摘要：
1-Aminocyclopropanecarboxylic acid non-hydrate can be obtained by
treating 1-aminocyclopropanecarboxylic acid hydrochloride with a tertiary amine in the presence of a C 3 -C 4 alcohol and water, keeping the reaction mixture at 50°C or below,
collecting the precipitated crystal of 1-aminocyclopropanecarboxylic acid 0.5 hydrate by filtration, and heating the obtained crystal to 80 to 245°C.
