Abstract

1453007 Polycyclic carboxylic acids NARD INSTITUTE Ltd 4 Oct 1974 [4 Oct 1973 15 Feb 1974] 43099/74 Heading C2C [Also in Division D1] A saturated polycyclic carboxylic acid having the formula wherein R 1 to R 10 are each hydrogen or methyl, or its water soluble salt, is prepared by hydrogenating an unsaturated polycyclic nitride of the formula in the presence of a noble metal reduction catalyst, with or without an alcohol, to produce a saturated polycyclic nitrile of the formula and saponifying with alkali or hydrolysing. The compounds of Formula I may be used as sizing agents for paper manufacture.
