标 题 :Method for the continuous purification by distillation of the solvent methanol, used in the synthesis of propylene oxide
发明人：BASSLER PETER; GOEBBEL HANS-GEORG; TELES JOAQUIM HENRIQUE; RUDOLF PETER
权利人:BASF AG
摘要:Process for the continuously operated purification by distillation of the methanol used as solvent in the synthesis of propylene oxide by reaction of a hydroperoxide with propylene, with the methoxypropanols being separated off simultaneously, wherein the solvent mixture obtained in the synthesis is separated in a dividing wall column into a low-boiling fraction including methanol, an intermediate-boiling fraction containing the methoxypropanols as azeotrope with water and a high-boiling fraction including water and propylene glycol.

标 题:Catalyst for synthesis of vesicular phenoxy resins
发明人：BENNETT EVERETT W
权利人:JAMES RIVER PAPER CO
摘要:A catalyst for synthesis of vesicular phenoxy resins is disclosed. The catalyst includes a water-insoluble complex of a hydric phenol and a quaternary ammonium or phosphonium salt of the hydric phenol. Preferably, the hydric phenol is an intermediate of the phenoxy resin being produced. Dihydric phenols, such as sulfonyldiphenol are preferred. The invention further relates to a reaction medium for polymerization of phenoxy resins including the above-described catalyst and a solvent medium capable of dissolving the phenoxy resins and otherwise not interfering with the polymerization reaction. The solvent medium is advantageously free of toxic Methyl Cellosolve.

权利人:BRACCO IMAGING SPA; MILANO POLITECNICO
摘要:The present invention relates to the industrial preparation of non-ionic X-ray contrast agents. In particular, it relates to a process for the synthesis of lopamidol using a reactive extrusion process in continuous which enable an efficient conversion of the relevant key intermediates, preferably in the absence of any solvent. The invention further relates to the preparation of radiographic X-rays contrast agents or key intermediates thereof by exploiting the technology of reactive extrusion.
