Participants

Reaction Steps

3,5-di tert.butyl-4-hydroxyphenyl hydrogen maleate was prepared by stirring a mixture of 15.5 grams of 2,6-di tert.butyl hydroquinone, 10 grams of trifluoroacetic acid and 8.6 grams maleic anhydride for 12 hours at 35° C. to 40° C. Addition of 100 milliliters of water resulted in the precipitation of a light brown paste which crystallized when mixed with petroleum ether. The solid was filtered off and washed twice with petroleum ether yielding 10.5 grams of product melting at 120° C. to 125° C.
