    Abstract: The invention comprises a compound of formula PhNHCON(Me)OCHMeC­CH in which the phenyl group may be substituted by up to 2 Cl or alkyl radicals. Standard etherification and urea-formation reactions are used. Specified substituents are 3- or 4-Cl; 2-, 3- or 4-Me or Et; 3,4-Cl2; 3-Cl-4-Me, and 3-Me-4-Cl.ALSO:Herbicides contain compounds of formula PhNHCON(Me)OCHMeC­CH in which the phenyl group may be substituted by up to 2 Cl or alkyl radicals. These compounds are stated to be oil-soluble and readily emulsifiable, and may be used together with other herbicides such as ureas, s-triazines, pyridazones, carbamates, thiocarbamates, uracils and borates.

    Abstract: 3-N-acetoxyethylanilino-propine-1 is prepared by reacting beta-hydroxyethylaniline with propargyl chloride to give 3-betahydroxyethylanilino-propine-1 and reacting this with acetyl chloride. 3-N-betahydroxyethylanilinobutine-1 is obtained from N-beta-hydroxyethylaniline and 3-chloro-butine-1.ALSO:The invention comprises p-aminoazo dyes of formula wherein A is an aromatic or heterocyclic diazo radical which contains at least one alkyl, alkoxy, nitro, sulphonamide, alkylsulphonyl, acylamino, cyano or trifluoromethyl group or halogen atom but no carboxylic or sulphonic acid groups, B is the radical of an azo component free from carboxylic or sulphonic acid group, R1 is a radical which between the amino and acetylene groups contains 1-4 aliphatic carbon atoms some of which may be replaced by hereto atoms, which radical may also be further substituted and R2 and R3 are hydrogen or aliphatic radicals. The dyes are prepared by normal diazotization and coupling procedures using suitable components. The dyes may be used to colour fibres and other materials of acetyl-cellulose, polyamides, polyurethanes, polycarbonates and polyacryonitriles in orange, red and violet shades. In an example 4-nitroaniline is diazotized and coupled with 3-N-acetoxyethylanilino-propine-1 (see Group IV(b)). Further examples are specified.
