摘要： Disclosed herein are methods for preparing fluorided solid oxides by contacting an acidic fluorine-containing compound with an inorganic base to form an aqueous mixture having a pH of at least 4, followed by contacting a solid oxide with the aqueous mixture to produce the fluorided solid oxide. Also disclosed are methods for preparing fluorided solid oxides by contacting an acidic fluorine-containing compound with a solid oxide to produce a mixture, followed by contacting the mixture with a inorganic base to produce the fluorided solid oxide at a pH of at least about 4. The fluorided solid oxide can be used as an activator component in a catalyst system for the polymerization of olefins.

摘要： The present invention relates to a method for preparing nanoparticles by using laser and more particularly, a method for preparing nanoparticles by irradiating a laser beam to the mixture of a source material gas and a hexafluoride (SF6) catalyst gas, thereby improving the production yield of nanoparticles with energy saved. More particularly, the present invention provides the method for preparing the nanoparticles by using the laser wherein the laser beam of wavelength having the excellent energy absorption by the mixture gas of source material gas and catalyst gas is irradiated to the mixture gas so as to increase the reactivity of the source material gas with energy saved, which brings the effects of solving the problems of damaging environment due to the unreacted toxic source material gas incurred by the low production yield of the conventional nanoparticle preparation method and of making system complicated with the high cost when the discarded source gas is recovered and reused.

摘要： The present invention relates, in part, to the discovery that the presence of HF in a HCFC-244bb feedstream in a reaction for the preparation of HFO-1234yf results in selectivity changeover from HFO-1234yf to HCFO-1233xf. By substantially removing HF, it is shown that the selectivity to HFO-1234yf via dehydrochlorination of HCFC-244bb is improved.
