PRODUCTION OF HIGH BOILING POINT, HIGH AROMATIC SOLVENT

摘要

PURPOSE:To obtain the subject solvent having a low mixed aniline point and excellent solubility at a low preparation cost by once subjecting a kerosene distillate to reformation and distillation processes and further again subjecting only prescribed distillate to reformation and distillation processes. CONSTITUTION:A kerosene distillate or a raffinate remained after the recovery of n-paraffin from the kerosene distillate is reformed in the first reformation process and a distillate having a boiling point range of =220 deg.C is distilled and separated from the produced oil. The distillate is reformed in the second reformation process to distill and separate a distillate having a boiling point range of 185-220 deg.C, thus obtaining the objective solvent having a mixed aniline point of =21 deg.C, preferably =18 deg.C.
