Main uses：
1.Resorcinol is mainly used in rubber adhesives, synthetic resins, dyes, preservatives, medicine and analytical reagents and other main surface, resorcinol is similar to phenol, cresol, and formaldehyde to form polycondensates, can be used to make viscose silk and nylon tire cord binder, preparation of wood adhesive, used for vinyl materials and metal bonding, Resorcinol is the intermediate of many azo dyes and fur dyes, and also the raw material of p - azyl salicylic acid of pharmaceutical intermediates. Resorcinol has bactericidal effect, can be used as a preservative, added to cosmetics and dermatological drugs paste and ointment. Resorcinol derivative β-methyl umbellione is an intermediate in optical bleach, trinitroresorcinol is a detonator, and a considerable amount of resorcinol is used in the production of benzophenone UV absorbers. This product can irritate the skin and mucous membrane, can be absorbed through the skin quickly and cause toxicosis. The minimum lethal dose of subcutaneous injection in rats is 450mg/kg.

2.For the determination of nitrite and nitrate. In the presence of ammonia, zinc, lead, furanaldehyde, sugar and ketone can be detected by colorimetry. Also used in organic synthesis, pharmaceutical industry.

3.Used as an accelerator of epoxy resin curing and synthetic resin, adhesive, dye, medicine (p-amino salicylic acid) ultraviolet absorber. Also used for the synthesis of resorcinol formaldehyde resin adhesive. Resorcinol is an important organic chemical product and intermediates, in tires, rubber hoses and adhesive tape, use of resorcinol formaldehyde (RF) resin impregnation tree rayon and polyamide fibre cord, can increase between the tyre and rubber adhesive. With resorcinol cyanuric acid three aryl ester formaldehyde resin processing steel wire cord, can improve the bonding performance of steel wire for rubber. The strengthening effect of staple fiber in rubber matrix can be improved by adding resorcol, hexamethylenetetramine and silica into rubber compound. Bisphenylphosphonate resorcinol synthesized from resorcinol is a kind of non-halogenated flame retardant, which has high thermal stability and is suitable for modified polyether, polycarbonate, ABS resin and all kinds of thermoplastic resin and polyurethane plastics. Resorcinol also has certain bactericidal effect.

4.Used as a variety of organic medicine and dye manufacturing, fur dye intermediate. Pharmaceutical external use to treat eczema, psoriasis and other skin diseases. In the cosmetic industry, used in hair dye formulations (as a matching dye). Resorcinol is bactericidal and can be used as an antiseptic in cosmetics and dermatological pastes and ointments.

5.Used in medicine, dyes, rubber, plastics, photosensitive materials, chemical fiber, explosive industry, such as synthetic amino salicylic acid, dye eosin, benzophenone UV absorbent, etc., also used to prepare tire cord dip glue, foam urea formaldehyde resin foaming agent solution, and for acne cosmetics drug additives, germinating agent.

6.Used to make dyes, plastics, drugs, synthetic fibers and so on.
