    摘要： The present invention relates to an interfacial process for the production of polycarbonates having terminal, aliphatically bonded hydroxyl groups by reacting predominantly dihydric alcohols with phosgene or chlorocarbonic acid esters of predominantly dihydric alcohols and/or phenols using alkali liquors as HCl-binding agents and in the presence of inert solvents, the process according to the invention being distinguished by the fact that concentrated, aqueous alkali liquors are used as the HCl-binding agents and thiodiglycol, optionally mixed with additional monohydric and polyhydric alcohols, is used as the dihydric alcohol. The present invention further relates to the new polycarbonates produced according to the novel process and to the use of these new polycarbonates for the production of polyurethane plastics.

    摘要： Polyether polyols can be prepared by reacting polyols with epoxides in the presence of basic catalysts, by treating the polyether polyols containing the basic catalysts with OH-functional solid compounds of metals of groups III to VIII of the periodic system of the elements (Mendeleyev), the compounds being insoluble in the polyether polyols and having BET surface areas of from 10 to 1000 m2/g, isolating the solid inorganic compounds laden with the basic catalysts from the polyether polyol and using them in the reaction of polyols with epoxides, or bringing the isolated inorganic compounds laden with the basic catalysts into contact with the polyols that are to be used in the reaction with epoxides, separating those polyols from the inorganic compounds and delivering them to the reaction with epoxides.

    摘要： The present invention relates to a process for the production of bis-(4-hydroxyaryl)-alkanes by a heterogeneously catalyzed reaction of aromatic hydroxy compounds with ketones in at least two reactors connected in series, which, as the reaction progresses, are operated at higher temperatures, wherein the total quantity of ketone is divided between the individual reactors in such a manner that the higher is the temperature of the particular reactor, the smaller is the proportion per reactor, the highest possible reactor loading is maintained and the temperatures and temperature gradients are kept as low as possible.
