摘要： Thallous salts of Beta -dicarbonyl compounds, prepared by reaction of the Beta -dicarbonyl compounds with a thallous alkoxide, are treated with alkyl halides to give C-alkyl products in high yield, with acyl halides at room temperature to give Cacyl products, and with acyl halides at low temperatures to give O-acyl products. Thallous phenolates are esterified with acyl or aroyl halides. Anhydrides are also prepared, as are biaryls and bi-sec-alkyls. N-Heterocyclics, including purines and pyrimidines, are N-alkylated. Lactams are O-acylated or Nalkylated.

摘要： The present disclosure relates to a method and an apparatus for treating, sorting and recycling an oil-containing discharged catalyst. There is provided a method for treating, sorting and recycling an oil-containing discharged catalyst, wherein the method comprises the following steps: (A) cyclonic washing and on-line activation of a discharged catalyst; (B) cyclonic spinning solvent stripping of the catalyst; (C) gas stream acceleration sorting of a high activity catalyst; (D) cyclonic restriping and particle capture of the high activity catalyst; and (E) cooling of the gas and condensation removal of the solvent. There is further provided an apparatus for treating, sorting and recycling an oil-containing discharged catalyst.

摘要： A method for preventing fouling of a demister is disclosed. A process fluid is provided into a vessel. A gas is provided to a gas inlet of the vessel. The gas comprises a component that desublimates, crystallizes, solidifies, reacts, or a combination thereof, in the process fluid, forming a first solid. The gas is passed through the process fluid, the component of the gas forming the first solid, resulting in a component-depleted gas. The component-depleted gas is passed out of the process fluid, causing splashing or spurting of the process fluid and the first solid. The diverter section is provided between the demister and the gas inlet, the diverter section comprising a physical obstruction preventing the process fluid and the first solid from splashing or spurting onto the demister. In this manner, fouling of the demister is prevented.
