Abstract

Disclosed herein is a method of making a 2-(2,3-epoxypropyl)phenol by reacting a 2-allylphenol with an oxidant in the presence of a catalyst. A 3-chromanol can be formed as a by-product. The method can be used to make 2-(2,3-epoxypropyl)-6-methylphenol. Transition metal catalysts and peroxide oxidants can be used. Also disclosed is a composition comprising 1 to 90 weight percent of a 2-(2,3-epoxypropylphenol, 5 to 90 weight percent of a 2-allylphenol, and 0 to 40 weight percent of a 3-chromanol, and in particular, a composition comprising 1 to 90 weight percent 2-(2,3-epoxypropyl)-6-methylphenol, 5 to 90 weight percent 2-allyl-6-methylphenol, and 0 to 40 weight percent 8-methyl-3-chromanol.

Claims (2)

1. A composition comprising 1 to 40 weight percent 2-(2,3-epoxypropyl)-6-methylphenol, 30 to 90 weight percent 2-allyl-6-methylphenol, and 1 to 40 weight percent 8-methyl-3-chromanol, based on the total weight of the 2-(2,3-epoxypropyl)-6-methylphenol, 2-allyl-6-methylphenol, and 8-methyl-3-chromanol.

2. A composition comprising 5 to 90 weight percent 2-(2,3-epoxypropyl)-6-methylphenol, 5 to 90 weight percent 2-allyl-6-methylphenol, and 1 to 20 weight percent 8-methyl-3-chromanol, based on the total weight of the 2-(2,3-epoxypropyl)-6-methylphenol, 2-allyl-6-methylphenol, and 8-methyl-3-chromanol.
