Abstract

1,136,688. Polyallyl esters of benzene polycarboxylic acids. FMC. CORP. 31 March, 1967 [28 April, 1966], No. 14706/67. Heading C2C. Polyallyl esters of a benzene polycarboxylic acid are made by reacting an excess of allyl alcohol with a benzene polycarboxylic acid or anhydride at a temperature of 165-250‹ C. in the absence of a strongly acidic catalyst having a pK below 4, the reaction being carried out in the presence of an esterification catalyst having a pK a above 4 when temperatures below 190‹ C. are used, for a time sufficient to convert at least 90% of the acid to the polyallyl ester. Suitable acids and anhydrides for use as starting materials are, for example, o-phthalic, isophthalic, terephthalic, trimellitic, trimesic, hemimellitic, pyromellitic, mellophanic, pehrritic, benzene-pentacarboxylic and mellitic acids and phthalic anhydride, the inner anhydride of trimellitic acid and pyromellitic acid. Suitable catalysts are, for example, dibutyl tin oxide, tin oxalate and sodium oxalate. Examples are given of the preparation of (a) diallyl phthalate, (b) diallyl isophthalate and (c) triallyl mellitate.
