Abstract

1,230,473. Process for the preparation of derivatives of urea. FARBWERKE HOECHST A.G. 26 Aug., 1968 [24 Aug., 1967], No. 40712/68. Heading C2C. Compounds of the formula wherein R<SP>1</SP> represents a hydrogen atom, an alkyl group, an alkoxy group or a phenyl group, which phenyl group may be substituted by groups inert towards amido groups and N- carbonyl sulphamic acid chloride and R<SP>2</SP> represents a hydrogen atom, a mono- or disubstituted amino group, the substituents being inert towards amido groups and N- carbonyl sulphamic acid chloride, or an alkoxy group, or R<SP>1</SP> and R<SP>2</SP> are together a part of a heterocyclic ring, a represents an integer from 0 to 5 and b is 0 or 1, with the proviso that a and b must not both be 0 if R<SP>2</SP> represents a hydrogen atom, are obtained by reacting (a) 1 mol. of an organic amide of the formula with from 1 to 6 mols. of N-carbonyl sulphamic acid chloride in an inert solvent or diluent to form a N-sulphochloride of the formula wherein X is hydrogen or -SO 2 Cl with the proviso that at least one X is -SO 2 Cl, and (b) saponifying the N-sulphochloride to the corresponding carbamide. The inert substituent groups referred to above may be hydrocarbon groups, alkoxy and acyl groups which may carry further substituents, e.g. nitro groups, ester groups, cyano groups or aromatically bound halogen atoms. Step (a) of the process is suitably effected at -50‹ to + 100‹ C. and the intermediates may be obtained in the form of crystals. The hydrolysis step is suitably effected by the addition of water and heating, e.g. to 50-100‹ C. The products may be used as textile auxiliaries or stabilizers for plastic materials.
