How it is made
Via Sulfonation of Benzene ... In the process variation used today, the sulfonation of benzene is carried out continuously with sulfur trioxide alone so that only small amounts of sulfuric acid are contained in the sulfonation mixture and the addition of lime is not required. After neutralization with sodium sulfite, soda ash, or sodium hydroxide solution, the sulfonation product disodium benzene-1,3-disulfonate is mixed with excess sodium hydroxide and fed to an alkali fusion reactor at 320 - 350 °C.

The endothermic solid-state reaction yields a white powder, consisting chiefly of disodium resorcinate, sodium sulfite, and some excess sodium hydroxide. Depending on the method used, the product of the fusion reaction is treated with either a small quantity of water (in this case, solid sodiumsulfite which contains organic impurities, is obtained as byproduct) or a large quantity of water forming an almost saturated solution of the product. In both processes the dissolved disodium resorcinate is then reacted with sulfur dioxide, sulfuric acid, or hydrochloric acid to give resorcinol. The dissolved resorcinol is extracted with an organic solvent. The preferred solvent is diisopropyl ether, but benzene, 4-methyl-2-pentanone (methyl isobutyl ketone), or others can also be used. The solvent is then distilled off, and crude resorcinol is purified further by distillation in vacuum.
