Propioc Aldehyde is a colorless oily liquid with the structural formula of CH ∨ CCHO. Boiling point 59-61 ℃. It is miscible with water. It has dual properties of aldehyde and terminal alkyne. Easily oxidized. It can be mixed with ammonia solution of silver nitrate or Cuprous chloride As} J, the alkynyl compound is formed. use sodium hydroxide After treatment, it can be cracked into acetylene and sodium formate. It is prepared by oxidizing propargyl alcohol with chromic butyrate sulfuric acid solution or by adding acrolein after acetalization, and then eliminating the corrugation hydrogen and hydrolysis. Used as organic synthesis reagent. [1]
