Question

Melting point of s-benzylisothiouronium chloride salt of benzoic acid

Answer 1

Answer:

172-174° C.

Explanation:

172-174° C.

The yield of S-benzylisothiouronium chloride is nearly quantitative melting at 172-174° C. A lower-melting form (m.p. 146-148 °) is sometimes obtained. It is converted to the higher-melting form by recrystallization from ethyl alcohol, during which the solution is seeded with the higher-melting product.
