摘要：
A procedure was developed for determining 2-butyne-1,4-diol dioxyethyl ester in nickel-plating electrolytes in the presence of hydrogenation products. The difference in the bromination capacity of ethylene and acetylene bonds forms a basis for the direct potentiometric titration of ethylene hydrogenation products with potassium bromate and the back titration of excess bromate after the bromination of acetylene compounds. The relative error of determination was no worse than 4%.
