标题:Synthesis of polyol fatty acid polyesters using column with inert gas stripping
发明人：CORRIGAN PATRICK JOSEPH; KENNEALLY COREY JAMES; GRANBERG ERIC PAUL
权利人:PROCTER & GAMBLE
摘要:Processes for the synthesis of polyol fatty acid polyester by transesterification of a polyol comprise reacting polyol with a first portion of fatty acid lower alkyl ester to provide a first step reaction product in which substantially all of the polyol is reacted with at least one fatty acid lower alkyl ester. The processes then employ a multistage column providing substantial plug flow of liquid therein for further transesterification of the first step reaction product. Partially esterified polyol, a second portion of fatty acid lower alkyl ester and catalyst are fed to the column to form a mixture and cause further transesterification of the partially esterified polyol and fatty acid lower alkyl ester, with lower alkyl alcohol being formed as a by product. The resulting liquid mixture of reactants and product is passed in a first direction between adjacent stages through the column for further reaction of partially esterified polyol with fatty acid lower alkyl ester. An inert stripping or sparging gas is fed through the column in a second direction between adjacent stages, counter current to the flow of the liquid mixture between adjacent stages in the first direction, with radial shear agitation. The lower alkyl alcohol by-product of the polyol-fatty acid lower alkyl ester reaction is transferred from the liquid mixture to the inert gas.

标 题:Catalytic synthesis of reduced furan derivatives
发明人：SANBORN ALEXANDRA; BINDER THOMAS P
权利人:ARCHER DANIELS MIDLAND CO
摘要:The present invention relates to catalytic synthesis of furan derivatives from alkoxymethylfurfural ethers or acyloxymethylfurfural esters. More particularly, the invention pertains to furan derivatives obtained by use of a multifunctional catalyst system to carry out both hydrogenation of furan starting material and hydrolysis of the reduced furan derivative in a single reaction. The process allows recovering and recycling of alcohol or acid from the reaction product.

An inert sparging gas is fed through the column in a second direction between adjacent stages, counter current to the flow of the liquid mixture between adjacent stages in the first direction. The inert gas is directed through the liquid mixture to provide gas induce turbulence, such that the column reactor has a column ratio of at least 0.4/hour.

摘要:A process for synthesizing 5-((2-methyl-1H-imidazol-1-yl)methyl)furan-2-carbaldehyde from a mixture comprising a carbohydrate, an alkali or alkaline-earth metal chloride, hydrochloric acid, water, an organic solvent, namely a water-insoluble polar aprotic solvent, and optionally a phase-transfer agent, proceeds via the formation of 5-(chloromethyl)furan-2-carbaldehyde, without isolating this synthesis intermediate. A process also synthesizes a compound of formula (III) below:from 5-((2-methyl-1H-imidazol-1-yl)methyl)furan-2-carbaldehyde.
