Hydroquinone → Ethylene Oxide

Participants

Reaction Steps

346 parts of a compound represented by formula (8) ##STR10## (produced by Sanyo Chemical Industries, Ltd., reaction product of 1 mol of o-phenylphenol and 4 mol of ethylene oxide, trade name: Newpol OPE-40, OH value 162), 86.5 parts of acrylic acid, 400 parts of toluene, 21 parts of sulfuric acid and 6 parts of hydroquinone were charged and the mixture were heated. The produced water was distilled out together with the solvent, condensed and collected in a separator. When 18 parts of water was collected at the separator, the reaction mixture was cooled. The reaction temperature was 130°-140° C. The reaction mixture was solved in 500 parts of toluene, and 380 parts of an acrylate represented by formula (9) was obtained in the same manner as in Example 1. ##STR11## The viscosity (25° C.) was 120 CPS and refractive index was 1.543. The product was almost odorless.
