Abstract
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.
