Abstract: The invention is directed to an improved, reliably performable process for preparing triallyl isocyanurate (TAIC) by Cu2+-catalysed rearrangement of triallyl cyanurate (TAC) at at least 90°C. According to the invention, TAC and, if required, also a Cu2+ catalyst and solvent are fed continuously to a start reaction mixture after onset of the initially inhibited isomerization reaction, the isomerization is performed at from 90 to 160°C and an amount of reaction mixture equivalent to the amount of reactant is drawn off continuously and sent to the workup. Preference is given to effecting the isomerization in TAIC as the reaction medium.

Abstract: Preparation of triallylisocyanurate comprises rearranging triallylcyanurate in the presence of copper (II) salts (0.01-1 wt.%) at at least 90[deg]C, preferably 90-160[deg]C; introducing separately or in a mixture of triallylcyanurate and copper (II) salts into the triallylisocyanurate; cooling the reaction mixture at less than 90[deg]C; continuously adding the reaction mixture and isolating the triallylisocyanurate from the reaction mixture.

Abstract: The invention relates to an improved process for preparing triallyl cyanurate (TAC) by reacting cyanuric chloride with allyl alcohol in the presence of an alkali metal acid acceptor and in the absence of an organic solvent other than allyl alcohol. According to the invention, TAC is obtained in over 99% purity with an APHA colour number below 10 in a yield of over 90% when 3.9 to 6.0 mol of allyl alcohol and 3.0 to 3.2 equivalents of acid acceptor are used per mole of cyanuric chloride, cyanuric chloride and acid acceptor are added simultaneously or successively to anhydrous or at least 50% by weight aqueous allyl alcohol, and the reaction is performed in one or more stages at a temperature in the range of -5 to +50°C.

Abstract: The present invention relates to a process for producing postcrosslinked water-absorbing polymeric formations, comprising the steps of contacting water-absorbing polymeric formations P1 obtained by polymerization of ethylenically unsaturated acid-functional monomers or salts thereof in the presence of a crosslinker with a fluid F1 comprising a postcrosslinker, heating the water-absorbing polymeric formations in contact with the fluid F1 to a temperature in a range from 40 to 300° C. to obtain postcrosslinked water-absorbing polymeric formations P2, the water-absorbing polymeric formations P1 having a thermal stability, as determined in accordance with the test method described herein, of less than 3.0%. The invention also relates to water-absorbing polymeric formations, to the water-absorbing polymeric formations obtainable by this process, to water-absorbing polymeric formations based on crosslinked carboxyl-bearing monomers, to a composite comprising water-absorbing polymeric formations and a substrate, to a process for producing a composite, to a composite obtainable by this process, to chemical products comprising water-absorbing polymeric formations or a composite, to the use of water-absorbing polymeric formations or of a composite in chemical products and also to the use of triallyl isocyanurate as an internal crosslinker in the production of water-absorbing polymeric formations based on crosslinked carboxyl-bearing monomers.
