International Classification:

C07C 4700

US Classification:

568420, 568410, 568618, 568613, 568621

Abstract:

A particularly useful process which includes the steps of providing a feedstream comprising providing a source of formaldehyde formed by conversion of dimethyl ether in the presence of a catalyst comprising tungsten oxide; and (i) heating the feedstream with the heterogeneous acidic catalyst in a catalytic distillation column to convert methanol and formaldehyde present to methylal and higher polyoxymethylene dimethyl ethers and to separate the methylal from the higher polyoxymethylene dimethyl ethers is disclosed, and/or (ii) contacting the source of formaldehyde and a predominately dimethyl ether feedstream with a heterogeneous, condensation promoting catalyst capable of hydrating dimethyl ether under conditions of reaction sufficient to form an effluent comprising water, methanol, formaldehyde, dimethyl ether, and polyoxymethylene dimethyl ethers is disclosed. Unreacted dimethyl ether is recovered from the effluent and recycled to the formation of polyoxymethylene dimethyl ethers. The resulting dimethyl ether-free liquid mixture is heated in the presence of an acidic catalyst to convert at least the methanol and formaldehyde present to polyoxymethylene dimethyl ethers.

BP Corporation North America Inc. - Chicago IL

International Classification:

C07C 4109

US Classification:

568613, 568618, 568621

Abstract:

A particularly useful process which includes the steps of providing a feedstream comprising methanol, a soluble condensation promoting component capable of activating a heterogeneous acidic catalyst and a source of formaldehyde formed by conversion of methanol in the presence of a catalyst comprising copper and zinc, and heating this feedstream with the heterogeneous acidic catalyst in a catalytic distillation column to convert methanol and formaldehyde present to methylal and higher polyoxymethylene dimethyl ethers and to separate the methylal from the higher polyoxymethylene dimethyl ethers is disclosed. Advantageously, methylal and higher polyoxymethylene dimethyl ethers are formed and separated in a catalytic distillation column. By including within the column a section containing an anion exchange resin, an essentially acid-free product is obtained. Products can be used directly as a blending component, or fractionated, as by further distillation, to provide more suitable components for blending into fuel.

Appl. No.:

10/310624

Inventors:

Gary Hagen - West Chicago IL, US
Michael Spangler - Sandwich IL, US

International Classification:

C08G065/34

US Classification:

528/425000

Abstract:

A particularly useful process for continuous production of a source of formaldehyde which is an un-purified liquid stream derived from a mixture formed by oxidative dehydrogenation (oxy-dehydrogenation) of at least dimethyl ether using a catalyst containing silver as an essential catalyst component is disclosed. Advantageously, the source of formaldehyde according to the invention is provided to an integrated, continuous process for catalytic production of oxygenated organic compounds, particularly polyoxymethylene dimethyl ethers, which are suitable components for blending into fuel having improved qualities for use in compression ignition internal combustion engines (diesel engines).

International Classification:

C07C 6800

US Classification:

558277

Abstract:

A process of contacting a feedstream containing dioxygen, carbon monoxide, ether, and alkanol, which can be vaporized under conditions of reaction, with a blend of catalysts which are heterogeneous to the feedstream, under conditions of reaction sufficient to form a mixture containing at least one higher molecular weight oxygenated organic compound is described. In another aspect, this invention relates to a blend of catalysts consisting of at least one molecular sieve, natural or synthetic, which has been found useful for hydrocarbon conversion reactions and a catalyst comprising a metal halide or a mixed metal halide supported on active carbon, which is effective in catalyzing direct formation of organic carbonates.
