Use
Propargyl alcohol is used in metal plating and pickling and asa corrosion inhibitor of mild steel in mineral acids. It also finds application in preventingthe hydrogen embrittling of mild steel inacids. It is used as an intermediate for makingmiticide and sulfadiazine.. Chemical intermediate, corrosion inhibitor, lab reagent, solvent stabilizer, prevents hydrogen embrittlement of steel, soil fumigant.
