Guanidine carbonate - Preparation Method
Open Data Verified Data
after melting dicyanamide and ammonium salt (ammonium chloride) at 170~230 ℃, guanidine hydrochloride is formed by reaction, and then neutralized by adding sodium alkoxide, and then the free guanidine is allowed to absorb carbon dioxide, guanidine carbonate can be obtained.
