摘要： Esterification process for the prepn. of thermoplastic polycarbonates (A) from diphenols, carboxylic acid diaryl esters and opt. branching agents and/or monophenols at 80 - 400 degrees C and 0.01 - 1000 mbar, carried out in the presence of solid bed catalysts. Also claimed is the same process for the prepn. of thermoplastic oligocarbonate (B) at 80-290 degrees C and 0.5-1000 mbar. Pref. the catalysts are aluminosilicates or polybenzimidazoles. Esterification is continuous by passing the reagents over the bed. The catalyst concn. is 10-8 to 95 wt.% (w.r.t. diphenol). An alkali(ne earth) metal catalyst is also used.

摘要： Heterocyclyclarbonyl substituted benzofuranyl-ureas of formula (I) are prepared by reacting heterocyclylcarbonyl substituted 3-amino-benzofuranes with appropriate isocyanates or isothiocyanates. The unsubstituted ureas are transferred into substituted ureas by usual methods of substitution. The heterocyclylcarbonyl substituted benzofuranyl-ureas are useful as active ingredients in medicaments particularly for the treatment of acute and chronical inflammatory processes. A, D, L, R , R , R , R4 are as defined in the applications, R being a heterocyclic group.

摘要： Prepn. of aromatic polycarbonates (A) via oligocarbonate intermediates is by a min. two step melt esterification process, from diphenols and carboxylic acid diaryl esters, in the presence of catalysts, at 80 - 400 degrees C and 0.01 - 1000 mbar, where the oligocarbonate prepn. step is carried out in at least one continuously working tubular reactor. Pref. the reactor operates at 180-250 (190-230) degrees C and 0.005-1 (0.01-0.8) bar. The oligocarbonate intermediate has a wt. ave. mol. wt. of 750 - 10000. Prod. is supplied to the base of the vertical reactor and the heating flow for the reactor goes in the opposite direction to the prod. flow. The eta m region for the oligomerisation condensation reaction is 1 - 10000 mPa.s.
