摘要： A dehydrofluorination process is disclosed for making hydrofluoroolefins of the structure RfCH═CHRf, wherein each Rf is independently a perfluoroalkyl group or a perfluoroalkyl group having a terminal hydrogen. The process involves reacting RfCH2CHFRf with a basic aqueous solution to produce a product mixture comprising RfCH═CHRf.

摘要： The present invention relates to an improved chlorosulfonic acid (CSA) composition useful in making a high clarity sulfated salt of a C.sub.8-22 natural or synthetic predominantly straight chain aliphatic primary alcohol to a process for making the improved CSA composition and to improved CSA composition by the process.The CSA contains less than 1 weight percent sulfuric acid, less than 0.47 weight percent sulfur trioxide, less than 5 parts per million iron and less than 0.5 relative percent pyrosulfuryl chloride.The CSA process involves contacting the hydrogen chloride and sulfur trioxide at the point of reaction with from 0.75 to 1.5 weight percent sulfuric acid based on the stoichiometric rate of CSA produced from the sulfur trioxide with an excess of hydrogen chloride.

摘要： A composition and processes for producing the composition are provided. The composition comprises titanium chelates having the formulae of TiXm(OR)4−m, TiXm(OR)(4−m)/2(OR1)(4−m)/2, and TiXm(OR1)4−m in which X is a radical derived from a chelating agent such as, for example, a diketone, a diester, a ketoester, or combinations of two or more thereof; m is a number from about 1.5 to about 2.5; each R and R1 is independently an alkyl group containing from 1 to about 10 carbon atoms per radical; and R1 differs from R. The process can comprise contacting at least one tetraalkyl titanates with a chelating agent to produce a product mixture comprising a titanium chelate and an alcohol, substantially removing the alcohol to produce an alcohol-reduced titanium chelate, optionally contacting the alcohol-reduced titanium chelate with a second, and further optionally reducing the alcohol content of the titanium.

摘要： A process is disclosed for converting a spent catalyst from conventional fluorination processes into a commercially useful tantalum or niobium salt such as K.sub.2 TaF.sub.7 or K.sub.2 NbF.sub.7. The process broadly relates to dissolving the spent catalyst in water or an aqueous hydrofluoric acid solution, separating and disposing the undissolved residue, extracting the aqueous solution with a suitable solvent such as methyl isobutyl ketone (MIBK), and obtaining useful tantalum products from the MIBK solution such as a tantalum salt.
