Abstract: PURPOSE:To obtain a polycarbonate having a high purity and excellent electrical insulation properties by removing a basic substance contained in a polycarbonate, prepared in the presence of a basic catalyst, by washing with water and/or by contact with an inorganic ion exchanger. CONSTITUTION:A polycarbonate is prepared in the presence of a basic catalyst (e.g. NaOCH3), and the contained basic substance is removed from this polycarbonate by washing with water and/or by contact with an inorganic ion exchanger (e.g. zeolite). According to the above process, a polycarbonate freed from the basic substance and excellent in electrical insulation properties can be easily prepared.

Abstract: PURPOSE:To obtain the title compound useful as a synthetic intermediate for polyurethane, etc., in high yield, by bringing a condensate of aniline and formaldehyde into contact with hydrogen in the presence of a hydrogenating catalyst in a gas phase. CONSTITUTION:An aniline is obtained from a condensate of aniline and formaldehyde. In the operation, the condensate is brought into contact with hydrogen in the presence of a hydrogenating catalyst especially preferably containing metals such as Fe, Co or Ni of group VIII in a gas phase. Temperature wherein the condensate is brought into contact with hydrogen is usually 200-700 deg.C, preferably 300-550 deg.C. The reaction in the gas phase is carried out under reduced pressure, normal pressure or under pressure and usually the reaction pressure is set at 0.1-20 atm., preferably normal pressure -5 atm. and the reaction is done. By this method, aniline can be recovered from a high polymer condensate of aniline and formaldehyde, such as polymethylene polyphenylamine.
