PROBLEM TO BE SOLVED: To provide a method for producing the subject inhibitor more economically, safely and simply in a manner suitable for massive production by grinding a mixture of a salt hydrate and support crystal for supercooling inhibitor. SOLUTION: This method comprises mixing a salt hydrate with a support crystal for supercooling inhibitor, referably in a wt. ratio of 1/5 to 5/1, while grinding them. It is preferable to use sodium acetate trihydrate as the salt hydrate and disodium hydrogen phosphate as the support crystal. The grinding can be effected by use of a ball mill, vibration ball mill, roller mill or the like. It is preferable to keep grinding temperature at the melting point of the salt hydrate or lower. The mixing/grinding is normally effected in the air. |
