Abstract: (I), having formula OCN-(CH2)5-CH(NCO)-(CH2)5-NCO, is new. (I) is prepd. by reacting 1,6,11-undecane-triamine, (II), or a salt thereof, with phosgene in an inert organic medium, either (i) at 60-230 degrees C., or (pref.) (ii) at 40 degrees C. with pyrolysis of the carbamoyl chloride obtd. in the presence of phosgene at 60-230 degrees C. (I) is used for preparing polyurethanes, esp. for coating compsns., by reaction with a polyol. Paint media can be used for cars, railways, containers, aeroplanes, seamless floors, coils, ships, railways, containers, aeroplanes, seamless (I) is less toxic than other aliphatic isocyanates, e.g. hexamethylene diisocyanate; is stable to alkali; boils at 166-177 degrees C./0.2 Torr; is easily purified by vacuum distn. and causes no irritating smell or vapour; and has low viscosity. The polyurethanes obtd. are glossy, stable to water, acids, bases, solvents and light.

Abstract: Cyclohexane derivatives such as cyclohexanol and cyclohexyl carboxylates are produced directly from aromatic hydrocarbons. The reaction may be carried out, under hydrogenation conditions, by reacting an aromatic hydrocarbon with hydrogen and a reagent selected from the group consisting of water, and carboxylic acids in the presence of a strong acid and a hydrogenation catalyst.

Abstract: Aliphatic 5-12C dicarboxylic acids (I) are prepd. by (i) reacting a 5-12C cyclomonoalkene (II) with a 4-12C aliphatic dicarboxylic acid (III), in the presence of an acid catalyst, pref. at 80-180 degrees C, and (ii) oxidising the obtd. cycloalkyl esters of (III) with HNO3, pref. at 40-120 degrees C. (I) are starting materials for prodn. of synthetic fibres, plastic compsns. and plasticisers. (II) are cheap and easily available. (III) are not lost during oxidn. and can be recycled. Acid catalyst for esterification in (i) may be H2SO4, a sulphonic acid or a cation exchanger resin, esp. contg. acid gps. in which H atoms are partly replaced by metal ions. Oxidn. catalyst in (ii) may be a combination of soluble V- and soluble Cu cpds.

Abstract: There is provided a novel aliphatic triisocyanate, 1,6,11-undecanetriisocyanate having the formula, and a method for production of the same. The novel triisocyanate is produced by reacting 1.6,11-undecanetriamine or its salts with phosgene. A non-yellowing polyurethane prepared therefrom provide an excellent coating composition.
