The Uses of 1,4-Dibenzyloxybenzene

1,4-Dibenzyloxybenzene is a medium-strength rubber anti-aging agent, non-polluting, and does not change color under long-term sunlight exposure. Mainly used in the manufacture of sponge rubber products.

Preparation

1,4-Bis(benzyloxy)benzene is synthesized by the reaction of hydroquinone and benzyl chloride.

What are the applications of Application

1,4-Dibenzyloxybenzene can be used as:
(1) Continuous debenzenization reaction. The continuous debenzenization of 1, 4-diphenoxybenzene (1a) with H2 and Pd catalysts in high pressure CO2 + tetrahydrofuran was studied, and the relevant parameters and catalysts were compared.
(2) Filler relationship between 1,4-Dibenzyloxybenzene and 4-Benzyloxyphenol.
