摘要： PROBLEM TO BE SOLVED: To enable the simple and efficient removal of impurities from sulfur hexafluoride containing the impurities therein by bringing the sulfur hexafluoride into contact with a purifying agent composed of one or more compounds selected from an alkaline earth metal compound, an alkali metal aluminate and a tetraalkylammonium salt and a carbonaceous solid. SOLUTION: SF6 containing impurities contains one or more selected from the group consisted of HF, SO2 , S2 F2 , SF2 , SF4 , S2 F10 , SOF2 and SO2 F2 . The SF6 is brought into contact with a purifying agent composed of one or more compounds selected from an alkaline earth metal compound, an alkali metal aluminate and a tetraalkylammonium salt and a carbonaceous solid and purified. The alkaline earth metal compound is selected from an oxide, a hydroxide, a carbonate and a nitrate of calcium, magnesium, barium and strontium. The alkali metal aluminate is selected from lithium alminate, sodium aluminate, potassium aluminate and cesium aluminate and the tetraalkylammonium salt it tetramethylammonium hydroxide, etc., carbonaceous solid is one or more of coke powder, coal, pitch, etc. The specific surface area of the purifying agent is 8-1,000 m2 /g.

摘要： Noble metal, particularly ruthenium, Raney catalysts which can hydrogenate (1) aromaticity-exhibiting ring portions of organic compounds, (2) carboxylic acids and their ester portions (carbonyl ester groups), (3) ring portions and carboxylic acid or their ester groups in compounds having such ring portions and carboxylic acid or their ester portions, and (4) ring portions and nitrile groups of aromatic nitrile compounds and methods for the preparation of corresponding hydrogenated compounds. The methods allow preparation of hydrogenated compounds having hydrogenated aromatic ring portions, hydrogenated carbonyl ester groups, hydrogenated aromatic ring and carbonyl ester groups, or hydrogenated aromatic rings and nitrile groups under milder hydrogen pressure and temperature conditions than the conventional catalysts.
