摘要： An improved silver catalyst for the oxidation of ethylene with molecular oxygen is made by impregnating a porous support with a silver salt of an acid; subjecting the impregnated support to a multi-stage activation in an atmosphere containing less oxygen than air by heating at a first temperature in the range of 150.degree. to 200.degree. C. for less than an hour, heating at a second temperature in the range of from greater than 200.degree. C. to 300.degree. C. for less than one hour, heating at a third temperature in the range of from greater than 300.degree. C. to 400.degree. C. for less than one hour and finally heating at a fourth temperature in the range of from greater than 400.degree. C. to 500.degree. C.; and post impregnating the support with an alkali metal, preferably cesium, from an anhydrous alcohol solution followed by washing with alcohol solvent and rapid drying to produce a finished catalyst having from 1-6.times.10.sup.-3 gew of the alkali metal per kg of catalyst.

摘要： A method of converting olefins to chiral epoxides comprises combining an asymmetric aliphatic or aryl alkene substrate with a buffered chloroperoxidase solution to form a stabilized reaction mixture, and gradually adding hydrogen peroxide as a substrate oxidant, such that the chloroperoxidase catalyzes the conversion of the substrate to the corresponding epoxide in enantiomeric excess. The products of the invention are alkyl and aryl non-primary epoxides. The resulting preparations are enantiomerically pure, and may greatly enhance large-scale synthesis of stereoisomer products such as pharmaceuticals and pesticides.

摘要： The oxidation of olefinic compounds generally using hydroperoxides, especially aqueous solutions of hydrogen peroxide, can be effected in high yield and with good selectivity in the presence of a titania-supported titanosilicate catalyst. Dilute aqueous hydrogen peroxide solutions may be used with good results. The resulting epoxidation, even when carried out at modest temperatures and with dilute aqueous hydrogen peroxide solutions, afford superior results in epoxidation relative to TS-1.

摘要： Disclosed are improved processes for the recovery of 3,4-epoxy-1-butene (EpB) from an epoxidation effluent comprising EpB, butadiene, oxygen and butane obtained by the selective epoxidation of butadiene with an oxygen-containing gas in the presence of a catalyst and an inert gas. EpB is separated from the effluent by means of an absorption process using liquid mixture of butadiene and butane as the absorbent material. The inclusion of butane in the epoxidation and recovery processes permits the use of lower pressures in the absorption of the EpB product.

摘要： The production of ethylene oxide by the catalytic vapor phase oxidation of ethylene with a molecular oxygen-containing gas is effected in a reactor provided with a preheating zone, a reaction zone, a cooling zone, a partition plate separating the first two portions from the third portion, and a multiplicity of reaction tubes piercing the two separated sections by a method which comprises supplying hot water to the cooling zone of the reactor, forwarding zone of the hot water discharged from the cooling zone to a gas-liquid separation tank, circulating the remainer of the hot water in conjunction with the cooling hot water to the cooling zone, supplying the hot water separated in the gas-liquid separation tank to the reaction zone to remove the heat of the oxidation reaction, and circulating the hot water extracted in the form of a gas-liquid mixed phase to the gas-liquid separation tank. The method is excellent to prevent isomerization of ethylene oxide to acetaldelyde which is impurity, excels in thermal efficiency and exhibits ideal durability of the partition plate.
