摘要： This disclosure relates to the processes for producing polycarbonates from specific crude bisphenols. The bisphenols are characterized in that immediately after their preparation they are subjected to (i) separation, of excess phenols and low-boiling substances, by means of an evaporator, and (ii) removal of monophenols by desorption.The invention also relates to high-molecular weight aromatic polycarbonates made of crude bisphenols and their use in a variety of applications.

摘要： The present invention is concerned with aromatic thermoplastic polycarbonates which contain at least about 0.5 mole % of structural units derived from 1,1,3,4,6-pentamethyl-3-(3,5 dimethyl-4-hydroxyphenyl)-indan-5-ol. The polymers disclosed herein may be homopolymers of these units or copolymers with other aromatic dihydroxy compounds and/or tri or higher functional branching agents. These homopolymers or copolymers may be used per se or they may be blended with other thermoplastic resins, particularly other aromatic polycarbonates. In addition, these polymers may be used to prepare coatings which may be cross-linked by heat treatment or radiation or they may be used as the base for graft polymerization.

摘要： A process for the preparation of aniline by hydrogenation of nitrobenzene in the gas phase in the presence of a catalyst containing a noble metal is described. The process can be carried out in an improved manner if the catalyst employed is palladium on graphite or petrol coke, as the support, containing 0.001-1% by weight of Pd, based on the total weight of the catalyst, it being possible for the catalyst also to contain, in addition to the Pd, 0.001-0.5% by weight of Ir and/or 0.001-0.3% by weight of Rh, all figures being based on the total weight of the catalyst.
