An unexpected displacement of one of the phosphorus groups occured when the chloride 1a was replaced by the sulfate 1b in its reactions with 1,3-dimethylurea.The products, 2c and 5c, were bisulfates rather than sulfates.In contrast, no displacement occurr

Novel quaternary ureidomethyl phosphonium salts having the general formula STR1 are prepared by condensing a urea having the formula RNHC(O)NR'R" with a quaternary hydroxymethyl phosphonium salt having the formula (HOCH2)4 P+ X- in a molar ratio of at least 2:1. The products, which are characterized by the absence of residual hydroxymethyl groups, are useful as finishing agents for imparting flame retardant properties to cotton fabrics.
