Water‐soluble vegetable oil derivatives were synthesized and investigated as biobased reagents for cellulosic textiles. Maleinized soybean oil (MSO), having an acid value of 156 mg KOH/g, was neutralized with ammonium hydroxide to render it water soluble. Infrared spectroscopy indicated the formation of ester linkages during the cure of MSO treated textiles. Therefore, the formation of anhydride and amide intermediates upon heating ammonia neutralized MSO were investigated. Construction of the cyclic anhydride was observed as a pathway to esterification; however, amidation was not observed among this ammonia neutralized MSO. Neutralization of MSO with ethanolamine and triethylamine yielded secondary and tertiary amides but not esters at 160 °C.
