Abstract
A study was made of the conjugation of soybean and linseed oils with dimsylsodium and dimsylpotassium as catalysts. Dimsylpotassium had markedly greater catalytic activity than dimsylsodium. The most effective cosolvent used with dimethyl sulfoxide for the conjugation at room temperature was tetrahydrofuran. Bis(2-ethoxyethyl) ether was less effective as a cosolvent than tetrahydrofuran at room temperature but was nearly as effective at 50 C. An adduct with maleic anhydride was prepared from the conjugated linseed oil under mild conditions. Drying characteristics of the conjugated linseed oil also were investigated. Baked conjugated linseed oil films were comparable to baked dehydrated castor oil films.
