Production of 2-ethylhexanol-(1) by hydrogenation of 2-ethylhexen-(2)-al-(1)

摘要

An improved process for the production of 2-ethylhexanol-(1) which comprises contacting 2-ethylhexen-(2)-al-(1) in an inert solvent with hydrogen at pressures of 1 to 500 atmospheres gauge and at temperatures of 80 DEG to 200 DEG C in the presence of a hydrogenation catalyst consisting essentially of cobalt and/or nickel and of copper and manganese and 0.5 to 15% by weight calculated as phosphorus pentoxide and based on the metal content of said catalyst exclusive of support of pyrophosphoric acid or polyphosphoric acid in free form and/or in the form of at least one salt of said metals. The alcohol produced is used as a solvent or for the production of plasticizers for polyvinyl chloride.
