摘要： The invention relates to a method for producing phthalic anhydride according to specifications by the distillative purification of crude phthalic anhydride. According to said method, crude phthalic anhydride is fed to a distillation column which is operated at a reduced pressure, then the low-boiling constituents at the head or in the vicinity of the head of the distillation column are removed and the phthalic anhydride which conforms to specifications is recovered from the column through a lateral vent.

摘要： In the process for producing acetic anhydride and acetic acid by reacting methanol and methyl acetate, optionally together with dimethyl ether, with carbon monoxide, acetic anhydride and acetic acid are effectively produced with the use of a sequence of production facilities by carrying out separation of the low-boiling-point fraction consisting mainly of methyl iodide, methyl acetate and dimethyl ether with the use of at least two distillation zones, separating the catalyst of drops entrained from the vapor-liquid separation zone in at least one distillation zone and further by controlling the pressurization of the vapor-liquid separation zone and the above distillation zones under 5 bar to a pressure being larger than the atmospheric pressure.

摘要： In the purification of crude tetrachlorophthalic anhydride containing hexachlorobenzene as impurities, this invention relates to purification by decomposition in which crude tetrachlorophthalic anhydride is contacted with chlorine gas in fuming sulfuric acid or sulfuric anhydride in the presence of iodine or iodine trichloride to decompose the impurities and remove them or purification by washing in which hexachlorobenzene is separated by washing with a chlorinated solvent. This invention also relates to a process for purifying crude tetrachlorophthalic anhydride containing iodotrichlorophthalic anhydrides as impurities by applying a radical reaction treatment in a chlorinated solvent to convert iodotrichlorophthalic anhydrides to tetrachlorophthalic anhydride. Moreover, it relates to high-purity tetrachlorophthalic anhydride containing 10 ppm or less of hexachlorobenzene. With the process of this invention, it is possible to recover high-purity tetrachlorophthalic anhydride with extremely low contents of impurities readily in high yield.
