摘要： Disclosed is a process for producing glycolate ester oligomers. The process comprises reacting ethylene glycol and glycolic acid to produce a stream of glycolate ester oligomers and glycolic acid oligomers while simultaneously removing water. The stream of glycolate ester oligomers and glycolic acid oligomers has a low concentration of water and glycolic acid-ends, and thus is useful in a subsequent hydrogenation reaction to produce ethylene glycol.

摘要： Disclosed is a process for the continuous, semi-continuous or batch production of 3-buten-1-ol from 3,4-epoxy-1-butene wherein 3,4-epoxy-1-butene and formic acid are fed to a reaction zone having a catalyst solution comprising a palladium(0) compound, a tertiary phosphine, a trialkylamine and an organic solvent. Preferably in the operation of this invention, 3-buten-1-ol product and reaction side products serve as the organic solvent for the process. The preferred mode of operation is continuous addition of reactants to the reaction mixture with simultaneous, continuous distillation of a reaction product comprising 3-buten-1-ol.

摘要： Disclosed is process for the treatment of cyclopropanecarboxaldehdye (CPCA) which contains crotonaldehyde impurity with a base at elevated temperature to convert the crotonaldehyde to one or more higher boiling compounds followed by distillation to recover CPCA substantially free of crotonaldehyde. This selective reaction may be combined with a distillation to purify CPCA or in combination with the reaction of the CPCA in the treated mixture to produce a CPCA-derivative while avoiding or minimizing the formation of the analogous crotonaldehyde derivative.
