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.

摘要:Synthesis of tungsten pentahalide compositions having low impurity profiles are disclosed. The specific impurity profile permits deposition of high purity tungsten-containing films using vapor deposition processes or other semiconductor manufacturing processes without introduction of performance-impacting contaminants.

标题 :Synthesis of poly-alpha olefin and use thereof
发明人：SONG WEI; HEILMAN WILLIAM J
权利人:SHELL OIL CO
摘要:One or more oligomers of an olefin are prepared in the presence of a single-site catalyst. Preferably, the olefin is an α-olefin, and the oligomers are a poly-alpha-olefin (PAO). The PAO so prepared is completely or substantially free of tertiary hydrogen resulting from isomerization. Consequently, the PAO possesses improved biodegradability, improved oxidation resistance, and/or a relatively higher viscosity index. The PAO has many useful applications, such as a component of a lubricant.

标题 :Synthesis of linear polyoxazolidinones using uretdiones as diisocyanate component
发明人：QUELL AGGELIKI; THOMAS HANS-JOSEF; ELING BEREND
权利人:BASF SE
摘要:A process for preparing a thermoplastic polymer involves reacting at least components (a) to (b), in the presence of a catalyst composition (c). Component (a) is an isocyanate composition containing at least one uretdione diisocyanate (a-i), and component (b) is an epoxide composition containing at least one diepoxide (b-i). The catalyst composition (c) contains at least one ionic liquid (c-i), preferably selected from 1-ethyl-3-methyl imidazolium bromide, 1-benzyl-3-methyl imidazolium chloride. 1-butyl-1-methylpiperidinium chloride, 1-ethyl-2,3-dimethylimidazolium bromide, 1-(2-hydroxyethyl)-3-methyl imidazolium chloride, butyl-1-methylpiperidinium acetate, or mixtures of two or more thereof. A thermoplastic polymer obtained or obtainable from the process is useful for the preparation of a fibre or a molded article or as a modifier for another thermoplastic material.
