Abstract

548,626. Substituted ureas. BOON, W. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 13, 1941, No. 442. [Class 2 (iii)] Alkylene bis-ureas, X.CO.NR<SP>1</SP>.(CH 2 ) n .NR<SP>11</SP>- COY, where X and Y which may be alike are radicals of secondary aliphatic or heterocyclic secondary amines having a molecular weight not exceeding 120, R<SP>1</SP> and R<SP>11</SP> are alkyl groups not necessarily alike and which jointly contain not more than 8 carbon atoms, and n is 2 to 6, are prepared bv treating a mono-urea X.CO.- NR<SP>1</SP>.(CH 2 ) n .NHR<SP>11</SP> with a carbamyl chloride Y.COCl, or with phosgene to form a carbamyl chloride which is then treated with an aliphatic or heterocyclic secondary amine. When X and Y are alike the products are the same as those of Specification 548,625. Examples give the preparation of N:N<SP>1</SP>-dimethyltrimethylenediamine-N:N<SP>1</SP>-dicarboxylic bis-diethylamide, - N-carboxylic diethylamide-N<SP>1</SP>-carboxylic dimethylamide, and -N-carboxylic diethylamide- N<SP>1</SP>-carboxylic piperidide, N:N<SP>1</SP> - dimethylhexamethylene-N:N '-dicarboxylic bis-diethylamide and-N-carboxylic diethylamide-N<SP>1</SP>-carboxylic morpholide, and N:N<SP>1</SP>-diethylethylene-N:N<SP>1</SP>- dicarboxylic bis-diethylamide. Mono-ureas, X.CO.NR<SP>1</SP>.(CH 2 ) n .NHR<SP>11</SP> are prepared by causing a N:N<SP>1</SP>-dialkylalkylenediamine, NHR<SP>1</SP>.(CH 2 ) n NHR<SP>11</SP> to react with one molecular proportion of a carbamyl chloride Y.COCl. Examples are N:N<SP>1</SP>-dimethyltrimethylene- and -diethylethylene-diamine-N-carboxylic diethylamide.
