    Application: Manufacture of vinyl acetate, acetic anhydride, acetic ester, acetate, ethyl cellulose and chloro acetic acid. It can also be used in the field of synthetic fiber, binding agent,pharmacy, ferilizer and dyeing raw material, as solvent in the field of plastic, rubber and printing.

    Used in dye industry, plastic industry, medicine, rubber, etc.Resorcinol is mainly used for rubber adhesives, synthetic resins, dyes, preservatives, medicine and analytical reagent, such as primary side, resorcinol and phenol, cresol are similar, and formaldehyde condensation polymer, can be used in making viscose rayon and nylon tyre cord adhesive, preparation of cement, wood glue used for vinyl material and metal, resorcinol is many azo dye, fur dyes intermediates, raw materials and pharmaceutical intermediates for nitrogen base salicylic acid.Phloroglucinol has a bactericidal effect and can be used as a preservative in cosmetics and skin medicine pastes and ointments.The derivative of resorcinol -methyl umbelliferone is an intermediate of optical bleach, trinitroresorcinol is a detonator detonator, and a considerable amount of resorcinol is used in the production of diphenylketone ultraviolet absorbers.This product can irritate the skin and mucous membrane, can be quickly absorbed through the skin to cause poisoning symptoms.

    It is used in the manufacture of many organic drugs and dyes, and is an intermediate of fur dyes.External use of medicine for eczema, psoriasis and other skin diseases.In the cosmetics industry, used in hair dye formulations (as a complementary dye).Phloroglucinol has a bactericidal effect and can be used as a preservative. It is added to cosmetics and skin medicine pastes and ointments

    Soluble in water, ethanol, amyl alcohol, easily soluble in ether, glycerin, slightly soluble in chloroform, carbon disulfide, slightly soluble in benzene.

    Used in photosensitive film, medicine, dyestuff and chemical fiber industry
