    摘要： This invention is a two step process for converting linear paraffins to linear alpha olefins. In the first step the paraffins are cracked to a mixture of alpha and internal olefins by use of a cracking catalyst of a zeolite in combination with an alkali(ne earth) metal compound wherein the sum of the amount of the alkali(ne earth) metal in the compound plus any metal cation exchanged into the zeolite is in excess of that required to provide a fully metal cation-exchanged zeolite. The resulting olefin-containing cracked product is then converted to a substantially alpha olefin-containing product by contact with ethylene and a disproportionation catalyst at disproportionation conditions. The resulting products contains only small amounts of aromatics.

    摘要： Substantially quantitative yields of bibenzyl hydroperoxide and bibenzyl dihydroperoxide can be obtained when oxygen is reacted with bibenzyl (1,2-diphenylethane) in the presence of a minor amount of sodium bicarbonate at a temperature within the range of about 100.degree. to about 160.degree. C. to provide an oxidation product wherein the bibenzyl is substantially selectively converted to the bibenzyl hydroperoxides. The bibenzyl hydroperoxides can be used as raw materials for the production of propylene oxide by reacting the bibenzyl hydroperoxides with propylene.

    摘要： A process is disclosed for preparing products such as 2-hydroxytetrahydrofuran which comprises contacting unsaturated compounds such as allyl alcohol with carbon monoxide and hydrogen in the presence of a rhodium carbonyl catalyst and a bi-solvent system. The bi-solvent system includes an aromatic solvent and an amide solvent and may be materials such as p-xylene and acetamide. Such a system provides for easy catalyst recovery since the rhodium catalyst is selectively soluble in the p-xylene whereas the desired product is conversely selectively soluble in the acetamide phase.
