权利人:PFEIFER & LANGEN GMBH & CO KG
摘要:The invention relates to a process for the synthesis of a product saccharide, preferably of D-allulose from an educt saccharide, preferably from D-fructose under heterogeneous or homogeneous catalysis which includes chemical and/or enzymatic catalysis. The synthesis is performed in at least two reactors that are arranged in series and the reaction product exiting the first reactor is subjected to chromatographic separation before it enters the second reactor. Preferably, the chromatographic separation is integrated in a simulated moving bed.

标题:Synthesis of polyol fatty acid polyesters using column with inert gas stripping

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.

摘要:The present invention describes methods and apparatuses for the synthesis of 5-(chloromethyl)-2-furaldehyde (CMF) from saccharides in pure or crude form, the method comprising: (a) continuously contacting saccharides in pure or crude form, hydrochloric acid, and an organic solvent, by way of a continuous, biphasic-flow reactor assembly at a temperature from about 60 degrees C. to about 200 degrees C. and pressures from about 1 atmosphere to about 20 atmospheres, such that CMF is produced; (b) separating 5-(chloromethyl)-2-furaldehyde by liquid/liquid and solid/liquid phase separation; (c) producing at least five kilograms per day with at least 50% yield. Embodiments of the present invention can produce CMF in a continuous fashion, with high yield and without degradation of CMF to such side products as 5-(hydroxymethyl)furfural (HMF), 2-(2-hydroxyacetyl)furan (HAF) and levulinic acid (LA).
