Abstract

PURPOSE: To obtain the titled substance continuously in high yield, by reacting phenol with α-methylstyrene in a given molar ratio in a reactor of the complete blending type in a suspension of a catalyst of cation exchange resin for a constant retention time.
CONSTITUTION: Phenol is reacted with α-methylstyrene in a molr ratio of ≥1.0 (preferably 2.5W3.5) in a container of the complete blending type in a suspension of a cation exchange resin catalyst for 10minW2hr (preferably 30W60min), to give the titled substance. A strong acidic cation exchange resin such as Lewatit SPC 118H, Amberlyst 15, etc. may be cited as the catalyst, and its amount to be fed per hour is 5W15wt% based on α-methylstyrene. The reaction temperature is preferably 90W110°C.
EFFECT: Dimerization of α-methylstyrene and preparation of o-cumylphenol as a by-product are suppressed.
USE: Germicide. A raw material for surface active agents, antioxidants, resins, etc.
