摘要:6,9-Oxido-9,10-seco-1,3,5(10),6,8,14-estrahexaenes, useful as intermediates in the total synthesis of steroids, of the formula ##SPC1## n Wherein n is 1 or 2, R 1 is lower-alkyl, R 2 , R 3 and R 4 are H, alkoxy or acyloxy, X is a free or ketalized keto or free, esterified or etherified hydroxymethylene, are produced by the cyclization, with an acid catalyst, of a 9,10-secoestrane of the formula ##SPC2## n Wherein R 1 , R 2 , R 3 , R 4 , X and n have the values given above and Q is carbonyl or dialkoxymethylene. Hydrogenation produces the corresponding 6,9-oxido-9,10-seco-1,3,5(10)-estratrienes and 9-oxy-9,10-seco-1,3,5(10)-estratrienes.

摘要:A method and a device for preparing a trivalent chromium salt by electrochemical oxidation of ferrochrome in an acidic system are provided. The method includes: putting ferrochrome as an anode and placing the anode into an acidic electrolyte together with a cathode, and then turning on a power supply for electrolysis reaction, until an electrolysis completion solution containing the trivalent chromium salt and a trivalent iron salt is directly prepared. Compared with the prior art, the one-step electrochemical synthesis of the trivalent chromium salt solution can be achieved without a hexavalent chromium salt stage, avoiding the generation of chromium-containing waste residue, shortening the process flow and significantly improving the production efficiency of the trivalent chromium salt; furthermore, the reaction can be carried out at room temperature and normal pressure without the use of fine chromium iron powders and a high-concentration acidic electrolyte.

标 题 :Synthesis of alkylaromatic compounds
发明人：IMAI TAMOTSU
权利人:UOP INC
摘要:Alkylaromatic compounds may be synthesized by reacting an aromatic compound with a mixture of carbon monoxide and hydrogen at alkylation conditions in the presence of a dual-function catalyst. The catalyst system will comprise (1) a composite of oxides of copper, zinc and aluminum or chromium, and (2) an alumino-silicate which may be either in crystalline or amorphous form.

摘要:The present invention relates to a process for producing ethanol, and optionally methanol, from synthesis gas. In particular the present invention relates to a process for producing ethanol from a carbonaceous feedstock; wherein the carbonaceous feedstock is first converted to synthesis gas which is then converted to methanol which is then converted to dimethyl ether which is then converted to methyl ethanoate, which is then hydrogenated to produce ethanol in the same alcohol synthesis unit used for converting the said synthesis gas to methanol.
