Process for reacting chloral with nitrogen compositions

摘要

A flame retardant composition is prepared by reacting chloral with a nitrogen compound having the formula: <IMAGE> (I) wherein: (a) X= <IMAGE> or, -SO2-; (b) Z is selected from O or S; (c) R1, R2, R3 and R4 are selected from the group consisting of H, alkyl of 1 to 6 carbons, and substituted or unsubstituted hydroxyalkyl of 2 to 4 carbons and mixtures thereof in a temperature range of 25 DEG to 100 DEG C., in the absence of a solvent and in an apparatus that provides efficient mixing. These compositions are useful for preparing flame retardant polyurethane foams.
