Introduction Little is known of the preparation and properties of the longer monoalkyl hydrogen esters of dibasic acids. The preparation of hexadecyl hydrogen succinate by the reaction of succiiiic anhydride with hexadecanol has been reported.'Herein are reported the preparation and X-ray diffraction patterns of the hexadecyl hydrogen esters of succinic, glutaric, pimelic, maleic and itaconic acid. Experimental hf. p.'s and analyses of the ...
