Abstract

チアゾール酸1.5水和物を安定的に無水和物に転移させる新しい晶析法を開発するために, 転移溶媒としてメタノールが最適であることを確認し, メタノール水溶液において種々の晶析を行った.その結果, 転移速度に及ぼすメタノール濃度, 晶析温度, 種晶添加効果および撹拌速度の影響を明らかにし, 安定的に無水和物へ転移させる晶析法を見い出した.

For the development of a new crystallization method to steadily transform hydrate crystals of a thiazol acid, (Z) - [4- (2-aminothiazolyl)] -2-methoxyiminoethanoic acid, to the anhydrate form, it was confirmed that aqueous methanol solutions were the most suitable solvents for the transformation and various crystallization experiments were carried out using the solvents.<BR>Influences of composition of solvent, crystallization temperature, seed crystals and agitation speed on transformation rate were studied.<BR>On the basis of these results, a crystallization method to obtain the desired anhydrate crystals was established.
