Propynyl alcohol ethoxylate is a colorless to pale yellow liquid that is soluble in common organic solvents and has rich chemical conversion activity. It can be used as an intermediate in organic synthesis and a raw material for nickel plating brighteners. It has good applications in basic chemical research and the metal electroplating industry PME has alkyne units and an active hydroxyl group, which makes it highly active in chemical reactions and can participate in nucleophilic substitution, condensation, and other reactions to construct complex organic molecular structures. In the electroplating industry, PME, as a raw material for synthesizing nickel plating brighteners, can improve the uniformity, brightness, corrosion resistance, and service life of the coating.
