STH the O - xylol for hromatogr. (3 ml)
Orthoxylol (au - Ksilol, IYuPAK: 1,2 dimethylbenzene) — organic substance, aromatic hydrocarbon. It is colorless liquid, mixes up with ethanol, diethyl ether, acetone, chloroform, benzene; water solubility less than 0,015% .
For synthesis processes of catalytic reforming of gasoline, and also pyrolysis of the gasoline subjected to hydrotreating ksilolovispolzutsya. For allocation of au xylol from formed smesiizomer use precision fractional distillation. Oxidation of au xylol in vapor phase at 450 — 600 °C (the catalyst — V2o5na SiO2) receive phthalic anhydride. Deep oxidation of au xylol of deystviyemazotny kislotyila of oxygen of air in liquid phase at 100 — 300 °C and 4 MPas (catalysts — bromidymn or With) poluchayutftalevy acid.
