Abstract
NEW MATERIAL:A 4-[ perfluoro-3- ( 1-methylethyl ) -4-methyl-2-penten-2-oxy ]- phthalic acid of formula I.
USE: A raw material for preparing a polyfluorinated curing agent for epoxy resins.
PROCESS: A compound of formula II alone or its mixture is condensed with a 4- hydroxyphthalic acid to give the compound of formula I. The reaction is carried out by dropping a tertiary amine to a solution containing either of the compounds of formula II or a mixture thereof and 4-hydroxyphthalic acid in an aprotic polar solvent, e.g. dimethylformamide or dimethylacetamide, at 30°C or below, e.g. room temperature, for 30W60min with stirring. The tertiary amine is suitably used in a molar amount of 1W3 times that of the compound of formula II.
