Abstract
A method for manufacturing nonylcyclohexanol is provided. The method includes steps as follows: adding a liquid phase reactant into a reactor, and the liquid phase reactant includes a molten nonylphenol and a catalyst; introducing a gas phase reactant to maintain a pressure of the gas phase reactant to be from 36.5 bar to 70 bar, and the gas phase reactant consists of hydrogen; rotating a hollow stirring shaft of the reactor at a temperature of from 100° C. to 130° C. so that the gas phase reactant is transported through a channel formed in the hollow stirring shaft into the liquid phase reactant for carrying out a reaction; obtaining a product that contains nonylcyclohexanol. A conversion rate of the nonylcyclohexanol is higher than or equal to 99.0%.
