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.
摘要:
The invention comprises anthraquinone compounds of the formula wherein R represents C1-C4 alkyl, and n is an integer from 1 to 3; S indicates that the ring is a cyclohexane nucleus. They may be obtained by reacting 1-amino-4-hydroxy-2-phenoxy anthraquinone or 1 - amino - 4 - hydroxy-anthraquinone - 2 - sulphonic acid or salt thereof with a cyclohexane methanol having in the molecule an etherified methanol substituent, in the presence of base. Examples are given for the production of compounds wherein R is CH3, C2H5, C3H7 or C4H9 and n is 1 and the CH2OR group is in the 2-, 3- or 4-position. They may be used for dyeing textile materials to give red shades.
摘要:
Vat dyes are made by condensing a 41:51-dichloroo 41:51-dibromo-11:81-naphthoylene-benz- or naphthimidazole or substitution product thereof with a 1-amino-anthraquinone in the presence of an acid-binding agent and heating the chlorine- or bromine-containing intermediate thus obtained in the presence of an acid amide which may be substituted at the nitrogen atom, such as acetamide, pyrrolidone, benzamide or phosphoric acid-tris-dimethylamide, and an acid-binding agent in the presence or absence of an organic liquid such as a -chloronaphthalene at temperatures from 150 DEG to 270 DEG C. Olive-green to green vat dyes are obtained.
