摘要： There is disclosed a process for producing highly pure terephthalic acid by converting a slurry of terephthalic acid crystals in acetic acid solvent which crystals are obtained by liquid-phase oxidation of p-alkylbenzene, into a slurry thereof in water solvent by mother liquor replacement and then subjecting the latter slurry to a catalytic hydrogenation treatment which process comprises the steps of introducing the slurry of terephthalic acid crystals in acetic acid into a mother liquor replacement column at the top portion; forming an accumulation layer of the terephthalic acid crystals at the bottom portion by the sedimentation of the crystals; feeding replacing water sufficient for the formation of upward rising stream of water to the inside of the column at the bottom portion; and withdrawing the accumulation layer of the crystals from the bottom portion of the column. The accumulation layer is kept at a slightly fluidized stable state and is smoothly withdrawn from the bottom of the column by slowly rotating an arm-type agitation blade placed in the layer or by feeding the replacing water dividedly into two trains.

摘要： A process for producing 3-methyltetrahydrofuran, wherein in a first step, prussic acid is reacted with methyl methacrylate to produce methyl 3-cyanoisobutyrate. The methyl 3-cyanoisobutyrate is then reacted with water and sulfuric acid to produce a resultant product which is reacted with a C.sub.1 -C.sub.8 aliphatic alcohol to produce a methylsuccinic acid ester. The methylsuccinic acid ester is catalytically hydrogenated to prepare the 3-methyltetrahydrofuran. Alternatively, the methyl 3-cyanoisobutyrate is hydrated to produce methyl 3-carbamoylisobutyrate, which is then reacted with a formic acid ester to form a methylsuccinic acid ester and formamide and the resultant methylsuccinic acid ester is catalytically hydrogenated. The 3-methyltetrahydrofuran is produced in high selectivity and in a commercially advantageous manner from inexpensive reactants. The 3-methyltetrahydrofuran is useful as a commoner for producing polyether glycol, which is utilized as starting raw material for preparing spandex fiber.

摘要： Proposed is an improvement in a method for the preparation of an enriched and purified aqueous hydrogen peroxide solution from a crude aqueous hydrogen peroxide solution comprising the steps of evaporating the crude aqueous hydrogen peroxide solution in an evaporator into vapor with accompanying liquid in the form of a mist, separating the vapor from the mist of liquid in a gas-liquid separator and subjecting the vapor to fractionating distillation in a fractionating distillation column in order to greatly upgrade the product solution relative to the impurity content. The improvement is achieved by subjecting the crude aqueous hydrogen peroxide solution, prior to introduction into the evaporator, to a contacting treatment with a porous synthetic adsorbent resin to remove organic impurities from the crude aqueous hydrogen peroxide solution to such an extent that the crude aqueous hydrogen peroxide solution after the contacting treatment contains organic impurities in an amount not exceeding 50 ppm by weight calculated as organic carbon. Although the mechanism is not well understood, the preliminary removal of organic impurities from the crude aqueous hydrogen peroxide solution has an effect of greatly increasing the efficiency of gas-liquid separation of the vapor accompanied by a mist of liquid in the gas-liquid separator to decrease the amount of contaminant impurities introduced into the distillation column as carried by the mist.
