Abstract
A process of preparing 2-trifluoromethylpropanol by vapor phase contact reaction between 2-trifluoromethylpropanal trimer and hydrogen in the presence of a catalyst of which the principal component is reduced nickel. The hydrogenation reaction can easily be completed at about 30.degree.-150.degree. C. and at the atmospheric pressure. The starting material is hydrogenated nearly theoretically and with very high selectivity factor for 2-trifluoromethylpropanol.
Claims8
A process of preparing 2-trifluoromethylpropanol, comprising the step of allowing a vaporized trimer of 2-trifluoromethylpropanal to contact and react with hydrogen gas in the presence of a catalyst which comprises reduced nickel as a principal component thereof.
