Product Applications

It is used for photosensitive film, medicine, dye and chemical fiber industry; It is the raw material for producing synthetic resin, adhesive, dye and ultraviolet absorber, and can be used for Tire Cord dipping, and used as disinfection preservative in medicine; used as analytical reagent; Resorcinol, also known as 1,3-hydroquinone, commonly known as resocine (res..

Production method

1. Benzenesulfonic acid is sulfonated and neutralized by fuming sulfuric acid, and then extracted by alkali fusion, acidification, n-butyl alcohol, and distilled off the solvent to obtain the finished product. 2. M-Phenylenediamine is prepared by the hydrogenation of M-dinitrobenzene, and then by the hydrolysis of M-phenylenediamine. 3. Made by hydrolysis of M-aminophenol. Resorcinol can also be produced by benzene and propylene using diisopropylbenzene peroxide, which is similar to cumene phenol.
