Physical properties of propargyl alcohol

 

         Colorless or yellowish liquid. There is a smell of geranium. Volatile. The polymerization is caused by heat or alkali, and the acidic aqueous solution can be inhibited. It can be miscible with water, benzene, ethanol, chloroform, 1,2-dichloroethane, diethyl ether, acetone, dioxane, tetrahydrofuran, pyridine, soluble in carbon tetrachloride, and not miscible with aliphatic hydrocarbons. combustible. Density 0.9715; melting point -53 ° C; boiling point 114-115 ° C; refractive index 1.43064; flash point 33 ° C. Avoid getting hot. Avoid contact with strong oxidizing agents, strong acids, strong bases, acid chlorides, and acid anhydrides.
