Abstract
By the control of the cyclization of 5-phenyl-2-hexene at a predetermined temperature, 1,4-dimethyltetralin is efficiently produced. The present invention provides a method for producing 1,4-dimethyltetralin, including a step of cyclizing 5-phenyl-2-hexene under reflux of solvents in the presence of acid catalysts.
Claims4
A method for producing 1,4-dimethyltetralin, comprising a step of cyclizing 5-phenyl-2-hexene under reflux of solvents in the presence of acid catalysts, wherein a reaction temperature is controlled in the step of cyclization by adjustment of an extraction amount of solvent in a reflux cooler.
