Process for the preparation of dry alkali metal salts of
1,8-naphthalimide
摘要:
Process for the preparation of dry alkali metal salts of 1,8-naphthalimide, which comprises allowing concentrated alkali metal hydroxide solutions to run into solid 1,8-naphthalimide in a molar ratio, at a rate corresponding to the degree of reaction, with vigorous stirring in vacuo at an elevated internal temperature, and then carrying out drying without intermediate isolation of the alkali metal salt formed.
