| titleOfInvention | Carboxylic ester derivatives of polycyclic phosphites, a process for their manufacture and products containing them |
| abstract | 1,211,235. Carboxylic-ester derivatives of polycyclic phosphites. CHEMISCHE WERKE ALBERT. 20 Oct., 1967 [20 Oct., 1966], No. 47899/67. Heading C2C. [Also in Divisions C3 and D1] The invention comprises reaction products of organic polycarboxylic acids with polycyclic phosphites of the formula wherein A is a C 1 -C 2 alkylene radical which may be substituted with one or more alkyl, cycloalkyl, aryl, alkoxyalkyl, alkoxyaryl and/or hydroxyalkyl radicals which substituents may be halogenated, and R and R<SP>2</SP> represent a cyclic or acyclic hydrocarbon radical which may be halogenated and/or substituted by a hydroxyalkyl, alkoxyalkyl, cycloalkoxyalkyl, aryloxyalkyl, acyloxyalkyl, aroyloxyalkyl, aroyloxyaryl, aryloxyaryl, alkoxyaryl, acyloxyaryl or aryloxyarylalkyl radical. The polycarboxylic acid may, for example, be a saturated aliphatic dicarboxylic acid with at least 4 carbon atoms. an unsaturated aliphatic dicarboxylic acid in which the carboxyl groups are each separated from the double bond by at least one carbon atom, an aliphatic, cycloaliphatic, aromatic or aromatic aliphatic polycarboxylic acid especially with one or two benzene nuclei, or a saturated or unsaturated polyester prepared from a polyhydroxy compound (e.g. a glycol) and another polycarboxylic acid. When a dicarboxylic acid of the formula R<SP>1</SP>(COOH) 2 , in which R<SP>1</SP> is a C 2 -C 20 aliphatic, cycloaliphatic or aromatic hydrocarbon radical which may be substituted by halogen atoms that are not accessible to the Michaelis-Arbusov reaction or by alkyl, cycloalkyl, aryl, alkoxyalkyl, alkoxyaryl or hydroxyalkyl groups, is reacted with a polycyclic phosphite of Formula (I) in equimolar proportions, the product may have the formula When two moles of the phosphite react with one mole of the acid, the product may have the formula In general, up to 10 carboxyl group equivalents in the form of polycarboxylic acid may be used per mole of phosphite. The reaction is generally carried out at 50-300‹ C. and solvents may be employed. Catalysts may be added to accelerate the reaction. In the examples, bicyclic trimethylolpropane phosphite is reacted with adipic acid, isophthalic acid and hexachloroendomethylene tetrahydrophthalic acid and bicyclic trimethylolethane phosphite is reacted with hexahydrophthalic acid, succinic acid, tetrabromophthalic acid and octanedioic acid. The reaction products are useful in the treatment, especially impregnation, of asbestos, slag wool and glass fibres, natural or synthetic fibres, paper, cardboard, wood fibres and textiles and may also be used to protect metals against corrosion, e.g. in the form of paints or lacquers. |
