| abstract |
The present invention relates to a method for reducing carbon and carbon triple bonds to double bonds through a hydrogenation reaction, and more particularly, the presence of an acetylene alcohol to a Lindla catalyst and a diamine-based reaction control agent represented by Formula 2 or 3 below. The selective hydrogenation method of acetylene alcohol, characterized in that it is selectively reduced to vinyl alcohol under.n n n Formula 2n n n n n n n n Where n is an integer from 1 to 5,n n n Formula 3n n n n n n n n Here, R 4 and R 5 are the same as or different from each other, H or an alkyl group having 1 to 5 carbon atoms, and includes a case where R 4 and R 5 are connected to each other to form a ring. |
