Abstract: Abstract The reaction of tetraalkylammonium salts of resin acids using dehydroabietic acid as the model with various alkyl polychlorides was studied as a method for preparing new ester derivatives of rosins. Of the alkyl halides investigated, methylene chloride, 1,1‐dichloroethane, 1,2‐dichloroethane, trichloroethylene and 1,2,3‐trichloropropane reacted with tetrabutylammonium dehydroabietate at moderate temperatures in short reaction times. A number of new esters were identified by NMR, IR and CI‐MS. Although many of the primary products were the anticipated monoesters and diesters, some dehydrochlorinated esters were also obtained. The reaction with trichloroethylene resulted in appreciable amounts of dehydroabietic acid anhydride.
