权利人:JIRO HIRAISHI DIRECTOR GENERAL
摘要:The present invention provides a process for synthesizing tertiary carboxylic acids or the esters thereof having one or two more carbon atoms than the raw material has, comprising reacting in a strong acid (e.g., sulfuric acid, sulfuric acid-phosphoric acid, hydrogen fluoride, fluorosulfuric acid, boron trifluoride.water complex and trifluoromethanesulfonic acid) a raw material compound (i.e., olefin, alcohol, diene, diol or saturated hydrocarbon) with carbon monoxide in the presence of a specific metal carbonyl catalyst (i.e., platinum carbonyl catalyst, palladium carbonyl catalyst and gold dicarbonyl catalyst). The metal carbonyl catalyst is formed by reacting in a strong acid at least one specific metal compounds (e.g., platinum compound such as platinum (II, IV) oxide, platinum (II, IV) hydroxide, a platinum powder, etc.; palladium compound such as palladium (II, III, IV) oxide, palladium (II) hydroxide, palladium (II) sulfate, palladium (II) carboxylate, a palladium powder, etc.; and gold compound such as gold (I, III) oxide, gold (I, III) hydroxide, a gold powder, etc.) with carbon monoxide.

标 题 :Method for the synthesis of supported gold (au) nanoparticles for epoxidation reactions
发明人：AL-HAZMI MOHAMMED H
权利人:SABIC GLOBAL TECHNOLOGIES BV
摘要:Processes for preparing supported gold nanoparticle catalysts are provided. In an exemplary embodiment, the process includes adding a solution of a phosphorus compound to a solution of chloro (dimethyl sulfide) gold (I) to obtain a solution of chloro (phosphorus compound) gold (I) complex, adding the solution of chloro (phosphorus compound) gold (I) complex to a solution of silver nitrate to obtain a solution of nitro (phosphorus compound) gold (I) complex, applying the solution of nitro (phosphorus compound) gold (I) complex to a metal hydroxide support, drying the metal hydroxide support; and calcining the dried metal hydroxide support to form the supported gold nanoparticle catalyst. Supported gold nanoparticle catalysts prepared by the process and processes for oxidizing ethylene to ethylene oxide in the presence of the supported gold nanoparticle catalysts are also provided.

标题:Stepwise growth of oligomeric redox-active molecules on a surface without the use of protecting groups

摘要:This invention provides a procedure for growing oligomers via a stepwise process. The oligomers can include porphyrins, which have been previously shown to be attractive candidates for molecular-based information storage. The stepwise synthesis procedure requires no protecting groups, thus eliminating protection/deprotection reactions that add complexity to the process.
