Abstract: Peroxides are prepared from organic compounds and oxygen in a reaction vessel by introducing organic compound and oxygen to the reaction vessel and by simultaneously withdrawing a first liquid product stream from adjacent the top of the reactor and a second liquid product stream from adjacent the bottom of the reaction vessel. Suitable organic compounds include, but are not limited to, alkanes and all aryl compounds.

Abstract: An improved method of recovering methyl tertiary butyl ether from an etherification reaction product containing acidic by-products wherein the reaction product is charged to an MTBE distillation zone and fractionated therein to provide a lower boiling distillation fraction comprising isobutylene, methyl tertiary butyl ether, methanol and acidic by-products, wherein the lower boiling distillation fraction is counter-currently washed with alkaline water in a methanol extraction tower, and wherein an aqueous solution of an alkali is injected into the tower below the charge point for the wash water to substantially completely neutralize the acidic by-products and to provide an overhead extract substantially free from acidic by-products comprising isobutylene, methyl tertiary butyl ether and a minor amount of water, and a bottoms raffinate comprising methanol, water, alkaline by-products and a minor amount of methyl tertiary butyl ether.

Abstract: MTBE, prepared by reacting MeOH with TBA to form a primary etherification reaction product, is distilled in a first distillation column to provide a first lower boiling distillation fraction comprising methyl tertiary butyl ether, isobutylene, methanol, dimethyl ether, and the first lower boiling fraction is water washed to provide an overhead extract that is distilled in a second distillation column to provide a second lower boiling distillation fraction comprising isobutylene, dimethyl ether and water, which is dewatered to provide a feed fraction comprising isobutylene and dimethyl ether that is reacted with less than an equivalent amount of MeOH to provide a secondary reaction product comprising MTBE, less than 0.5 wt. % of MeOH, isobutylene and contaminants including TBA and dimethyl ether, and the secondary reaction product is recycled to the second distillation column.

Abstract: Methyl tertiary butyl ether is sequentially prepared from tertiary butyl alcohol and methanol by:passing tertiary butyl alcohol and methanol through a primary reaction zone to form a primary etherification reaction product comprising unreacted methanol, unreacted tertiary butyl alcohol, water, dimethyl ether, isobutylene and methyl tertiary butyl ether;separating the primary etherification reaction product into a methanol recycle fraction, a tertiary butyl alcohol recycle fraction, an isobutylene fraction and a methyl tertiary butyl ether product fraction;recycling the methanol recycle fraction and the tertiary butyl alcohol recycle fraction to the methyl tertiary butyl ether etherification reaction zone;passing at least a portion of said isobutylene fraction together with added methanol through a secondary reaction zone to form a secondary etherification reaction product comprising water, methanol, isobutylene, DME, methyl tertiary butyl ether and tertiary butyl alcohol; andrecovering the methyl tertiary but

Abstract: Tertiary butyl hydroperoxide and tertiary butyl alcohol are prepared from isobutane and oxygen in a vertical reactor by sparging a mixture of isobutane with oxygen to the bottom of the reactor, by charging a reaction mixture recycle stream to the reactor above the sparge point, by centrally charging a downwardly flowing stream of cooled fresh isobutane to the top of the reactor to induce central downflow of the fresh isobutane annular and upflow of the sparged mixture and the recycle stream, by withdrawing a liquid product stream adjacent the top of the reactor, by withdrawing a vapor product stream from the top of the reactor, by condensing entrained liquids in the vapor product, by recycling the condensed liquids and by recovering the liquid product stream.

Abstract: Methyl tertiary butyl ether (MTBE) is formed by reaction of methanol with tertiary butyl ether in two catalyst beds. A feedstock mixture comprising methanol and tertiary butyl alcohol in a molar ratio of 2 to 3 moles of methanol per mole of tertiary butyl alcohol is reacted in a first etherification reaction zone at a liquid hourly space velocity of 1 to 10 volumes of feedstock mixture per volume of catalyst per hour. A first reaction product mixture is fractionated to remove unreacted methanol, isobutylene and MTBE overhead. This isobutylene is passed to a second etherification reaction zone at a liquid hourly space velocity of 1 to 10. A second reaction product mixture is fractionated to recover additional MTBE.

Abstract: In reacting tertiary butyl hydroperoxide in solution in tertiary butyl alcohol with propylene to produce propylene oxide and tertiary butyl alcohol in a reactor system comprising a first isothermal segment and a second adiabatic segment about 60 to 80 wt % of the tertiary butyl hydroperoxide is converted in the isothermal segment to provide an intermediate reaction mixture, a recycle stream comprising about 25 to 100 wt. % of the combined weight of the propylene and the tertiary butyl alcohol solution is removed from the intermediate reaction mixture and recycled to the first isothermal segment and the remainder of the intermediate reaction mixture is passed through the adiabatic segment where an additional 20 to 40 wt. % of the tertiary butyl hydroperoxide is converted.

Abstract: A method for the preparation of methyl tertiary butyl ether is provided wherein a mixture of methanol and substantially peroxides-free tertiary butyl alcohol are catalytically reacted to form a reaction product that is separated into a first lighter distillation fraction comprising isobutylene, methanol and methyl tertiary butyl ether and a second heavier distillation fraction comprising methanol, tertiary butyl alcohol and water, wherein the first distillation fraction and a first recycle isobutylene fraction are reacted to form an isobutylene conversion product that is charged, together with recycle isobutylene to a methanol extraction zone and countercurrently contacted with water to provide an overhead extract comprising aqueous isobutylene, and wherein the isobutylene is recovered and recycled.
