Abstract:
1-Aminocyclopropanecarboxylic acid non-hydrate can be obtained bytreating 1-aminocyclopropanecarboxylic acid hydrochloride with a tertiary amine in the presence of a C3-C4 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, andheating the obtained crystal to 80 to 245° C.
