标 题:Method for the synthesis of (meth)acrylic esters catalysed by a polyol titanate
发明人：PAUL JEAN-MICHEL
权利人:PAUL JEAN-MICHEL; ARKEMA FRANCE
摘要:The subject of the invention is a method for the synthesis of (meth)acrylic esters by transesterification in the presence of a catalyst corresponding to the formula [(R′O) 3 Ti] x R″ in which R′ is a linear or branched alkyl radical having from 2 to 8 carbon atoms which may contain heteroatoms or R′ is a phenyl radical, R′ is a polyfunctional radical, originating from a polyol R′(OH) x comprising x alcohol functional groups and x is an integer ranging from 2 to 6. The method according to the invention is particularly well suited to the synthesis of dialkylaminoalkyl (meth)acrylates from methyl (meth)acrylate and a dialkylaminoalcohol.

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).

标题 :Glycolysis of cured unsaturated polyesters for producing a recycle reactant
发明人：TUFTS TIMOTHY A; TSAI CHUNG-CHIEH; HUPP STEPHEN S
权利人:ASHLAND OIL INC
摘要:The present invention is directed to a method for treating cross-linked (cured) filled or untilled unsaturated polyester for deriving an alcohol recycle reactant useful in the synthesis of alcohol-formed derivative products. The first step of the method is the attrition of the cured unsaturated polyester to form particulates thereof. In the next step of the process, at least a fraction of any filler or fiberglass in the cured unsaturated polyester is separated to form a cured unsaturated polyester regrind. The next step is the subjecting of the cured unsaturated polyester regrind to agitated, uncatalyzed or catalyzed glycolysis in the presence of excess glycol and, optionally, a transesterification catalyst under agitation at elevated transesterification temperature. The final step of the process is the recovery of the recycle alcohol reactant for use in the synthesis of alcohol-formed derivative products. The glycolysis reaction is conducted under agitation in order to keep the cured unsaturated polyester regrind solids suspended during the glycolysis reaction. In this regard, establishment of shear conditions should aid in the glycolysis step of the process.
