Studies of reactions of 1,3,5-trimethylbiuret and 1,3-dimethylurea with chloroform
Abstract
1,3,5-Trimethylbiuret and 1,3-dimethylurea react with chloroform at temperatures above 200 °C to produce 1,3,5-trimethyl-1,3,5-triazinane-2,4-dione (4), 1,3-dimethyl-1,3,5-triazinane-2,4,6-trione (5), and 1,3,5-trimethyl-1,3,5-triazinane-2,4,6-trione [methyl isocyanate (MIC) trimer](3), besides minor quantities of other by-products, via trimerization reactions involving MIC, isocyanic acid, and N- methylenemethylamine.
