    摘要: A process for preparing 1-[1,5-di-(3,3-dimethylnorborn-2-yl)-3-pentyl]-1,5,9-triazanonane from 1,5-di-(3,3-dimethylnorborn-2-yl)-3-pentanone by reaction with ammonia to form, after reduction, 3-amino-[1,5-di-(3,3-dimethylnorborn-2-yl)pentane]. This latter compound is reacted with acrylonitrile, reduced, and the diamine product again reacted with acrylonitrile and again reduced. Alternative routes wherein the ketone is reduced to the novel alcohol and optionally the novel halide and either then reacted with 3,3'-iminobispropylamine to form the desired polyamine are also shown.

    摘要: Di-esters of thiodipropionic acid, HOOC-CH2-CH2-S-CH2-CH2-COOH, with cyclic terpene alcohols are used as costabilizers for polyolefins. Suitable cyclic terpene alcohols are, for example, tetrahydroabietyl, dihydroabietyl and dehydroabietyl alcohols, a -, b -, and g -terpinols and their hydrogenated derivatives (saturated alcohols), menthol and borneol. A mixture of esters, in particular a mixture of the esters of tetrahydroabietyl, dihydroabietyl and dehydroabietyl alcohols, may be used. The other stabilizer present in the stabilized mixture is a "hindered" phenol, i.e. a phenol having at least one C4 or higher tertiary alkyl group in the position ortho to the hydroxy group, e.g. 2,6 - di - t - butyl - 4 - methylphenol; 2-t-butylphenol; 4,41 - butylidene - bis - (3 - methyl - 6-t-butylphenol); 2,21-methylene-bis(4-methyl-6-t - butylphenol); 4,41 - methylene - bis(2,6 - di-t - butylphenol); 4,41 - (1,1 - butylidene - bis(3 - methyl - 6 - t - butylphenol a 2,a 6 - bis(3 t - butyl - 5 - methyl - 2 - hydroxyphenyl)-mesitol; 4,41 - thiobis(2 - methyl - 6 - t - butylphenol) and diterpene-diphenols. The polyolefins which may be stabilized are prepared from one or more olefins having 2-8 carbon atoms and preferably have molecular weights of 10,000-1,000,000.ALSO:The invention comprises di-esters of thiodipropionic acid, HOOC-CH2-CH2-S-CH2-CH2-COOH with a cyclic terpene alcohol. The preferred alcohols are derived from abietic acid, e.g. tetrahydro-, dihydro- and dehydro-abietyl alcohols but other suitable alcohols are a -terpiniol, b -terpiniol, g -terpiniol and their hydrogenated derivatives, borneol and menthol. The esters may be made by reacting the alcohol with the acid in the presence of a mineral acid and, if desired, a mixture of alcohols may be used.
