Abstract

PURPOSE: To obtain the title high-purity compound as a crystalline solid, by cooling a heated solution prepared from a p-isopropenylphenol oligomer brought into contact with a polar solvent, and by recycling the mother liquor after separation for collecting the phenol.
CONSTITUTION: p-Isopropenylphenol (A) produced by heating is oligomer is collected into a gas or by bringing the oligomer into contact with a polar solvent, e.g. methanol or ethylene glycol, right after condensation, and separated out in the form of a crystalline solid by cooling the solution at 10°C, preferably at 0°C or below, free from quenching, in three hours or longer. The mother liquor thus used is, with or without the additional fresh solvent, recycled for collecting A.
EFFECT: The object crystalline compound having a good storage stability permits the high purity of the monomer in a long term, and reduces the amount of solvent.
