Abstract
A method for producing alkylphenol is provided. The method includes charging phenol and an olefinic compound into a reaction zone of a reactive distillation tower for a reaction; and separating a product stream containing alkylphenol from the reactive distillation tower, wherein the boiling point of the olefinic compound is lower than that of the phenol, and the phenol is charged into the reactive distillation tower at a charging position located above a position for charging the olefinic compound.
