    摘要: The invention relates to a method for the production of polyisocyanate/polysilicic acid based resins with widely variable processability period and setting period by reacting one or more polyisocyanates with water glass optionally in the presence of one or more additives and/or auxiliary agents conventionally used in the production of polyisocyanate/polysilicic acid based resins. According to the invention the reaction is performed in the presence of one or more cocatalysts comprising mobile hydrogen of acidic character, wherein the cocatalyst is a compound comprising a structural unit of formula (I) a metal chelate thereof or a derivative thereof in which one of the mobile hydrogens of acidic character is replaced by a substituent X, wherein X represents halo, hydrocarbyl, hydrocarbyl-oxy, hydrocarbyl-carbonyl, hydrocarbyl-oxy-carbonyl or hydrocarbyl-carbonyl-amido group or a combined group formed from two or more of these groups, and the cocatalyst is used in an amount of at least 0.01% by weight calculated for the combined weight of polyisocyate(s) and water glass.

    摘要: It is a process for producing trimellitic acid (trimellitic acid, 1, 2, 4-tricarboxylic acid) by oxidizing pseudocumene with a molecular oxygen containing gas. More particularly, pseudocumene is oxidized into trimellitic acid by introducing a molecular oxygen containing gas in an acetic acid solvent in the presence of oxidizing catalysts, wherein the oxidization reactions in two different stages which have different ranges of temperature and different compositions of catalyst, respectively.
