Mainly used as the basic raw material for fine chemical products, parabens, ie, parabens, have been widely used as preservatives for food, medicine and cosmetics. They are also widely used in the preparation of dyes, fungicides and colors. Film film and various oil-soluble color formers, and a wide range of new high-temperature resistant polymers, p-hydroxybenzoic acid polyesters, are also used as basic materials.
