标题:Process for the synthesis of isocyanates and of isocyanate derivatives

摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.

摘要:Process for the continuously operated distillation of the solvent used in the synthesis of an oxirane by reaction of a hydroperoxide with an organic compound, wherein the mixture comprising the solvent which is obtained in the synthesis and subsequent work-up is separated in a dividing wall column into a low-boiling fraction, an intermediate-boiling fraction and a high-boiling fraction and the solvent is taken off as intermediate-boiling fraction from the side offtake of the column.

摘要:The invention is a two-step procedure for the formulation of a mixed catalyst of a nickel compound preferably with diene addition, boron trifluoride and an organo-aluminum compound, for the synthesis of cis-1,4-polybutadiene rubber, in which in each case, in a first step boron trifluoride was reacted as an etherate complex (BF3OEt2) with triethyl-aluminum (AlEt3) in toluene, with a contact time in each case of between 10 and 120 minutes; the active component of the catalyst formulation here was the amorphous AlF3 formed and where in a second step nickel carboxylate-also in toluene- was added to the mixture. The procedure is suitable for the synthesis of cis-1,4-polybutadiene rubber with a high cis-1,4 content and a molecular weight controllable over a wide range, with the goal of minimizing gel formation during the polymerization process.

标题 :Process for the synthesis of hydroxyl-end group functionalized polybutadienes
发明人：PETERS MARK A
权利人:BAYER AG
摘要:This invention relates to a process for the synthesis and purification of hydroxyl-end group functionalized, linear, non-crosslinked polyolefins without pendant chain branched groups, and specifically to hydroxyl-end group functionalized polybutadienes. The process comprises polymerizing a cyclic olefin monomer with a chain transfer agent in the presence of a suitable catalyst, thereby forming a protected end-group functionalized polyolefin, followed by adding a mixture comprising water and caustic to the protected end-group functionalized polyolefin to remove the protecting groups, thus forming a hydroxyl end-group functionalized, linear, non-crosslinked polyolefin without pendant chain branched groups.

摘要:By utilizing the vapor phase polymerization techniques of the present invention, numerous distinct and highly beneficial advantages are realized. For instance, cis-1,4-polyisoprene rubber and high cis-1,4-polybutadiene rubber having a consistent and controllable molecular weight can be easily and practically prepared without utilizing a solvent. The subject invention more specifically discloses a method for vapor phase polymerizing isoprene into cis-1,4-polyisoprene in a process comprising the steps of: (1) charging into a reaction zone said isoprene and a preformed catalyst system which is made by reacting an organoaluminum compound with titanium tetrachloride, preferably in the presence of at least one ether; wherein the isoprene is maintained in the vapor phase in said reaction zone by a suitable combination of temperature and pressure; (2) allowing said isoprene to polymerize into cis-1,4-polyisoprene at a temperature within the range of about 35 DEG C. to about 70 DEG C.; and (3) withdrawing said cis-1,4-polyisoprene from said reaction zone. It has been determined that gel formation can be reduced by conducting the polymerization of isoprene monomer in the presence of a diarylamine, such as para-styrenated diphenylamine.
