Open Data Verified Data
It is produced industrially by the interaction of molten urea with monomethylamine. The urea is put into the melting tank, heated to 130~135 ℃ to melt it, then transferred to the reaction Tower preheated to 110~120 ℃, and then heated to 150~175 ℃, the purified monomethylamine gas was started to be introduced, and the reaction was finished after all the monomethylamine was passed, so that the final product was obtained.
