Abstract:
This invention relates to a process for effecting alkylation of an isoparaffin with an olefin in the presence of a catalyst comprising a macroreticular acid cation exchange resin characterized by a surface acid concentration of less than about 0.5 milliequivalents of hydrogen ion per square meter surface area, boron trifluoride in an amount of at least about 0.1 equivalent per equivalent of resin acid groups but not in excess of that required to saturate said resin and hydrogen fluoride in an amount between about 0.1 equivalent and about 10 equivalents per equivalent of resin acid groups.
Abstract:
Alkyl aromatic compounds, such as ethylbenzene, are dehydrogenated by reaction with carbonyl sulfide in the vapor phase in the presence of either silica or a supported heavy metal catalyst, e.g., iron on an oxide carrier.
Abstract:
A catalyst comprising a base-exchanged, calcined manganese silicate-containing mineral in the form of a manganese nodule, said mineral having hydrogen ions bonded thereto in an amount of at least 0.01 gram per 100 grams of said mineral; a method of preparing the same from naturally occurring manganese nodules and organic compound conversion with catalytically-active forms of said nodules.
