Raschig 1
Raschig 1 :
(1) A process for making hydrazine by oxidizing ammonia with sodium hypochlorite in the presence of gelatine: NH3 + NaOCl + NaOH + H2NCl; H2NCl + NH3 + N2H4 + HCl. (2) Also called Raschig-Hooker. A two-stage regenerative process for making phenol from benzene. The benzene is first chlorinated with hydrochloric acid in the presence of air, at 200 to 260°C, over a copper catalyst on an alumina base: C6H6 + HCl + 1⁄2O2 + C6H5Cl + H2O. The resulting chlorobenzene is then hydrolyzed with steam, over an apatite catalyst at about 480°C: C6H5Cl + H2O + C6H5OH + HCl. (Check source for accuracy of chemical formula)
