The homologation is carried out by reacting methanol with hydrogen and carbon monoxide in a 1-2:1 mole ratio and a temperature of from about 175-230.degree. C. and a pressure of 2,000-10,000 psig in the presence of a cobalt catalyst represented by formulas I and II.

  • Patent number: 4126752
    Abstract: An improved process is described for converting methanol to ethanol in which a mixture of methanol, liquid water and a Group VIII metal catalyst and a basic inorganic compound is contacted with an atmosphere of carbon monoxide at a temperature of about 240.degree. to 280.degree. C and a pressure of about 3,000-5,000 psi gauge. Good yields and selectivities of ethanol are obtained eliminating the necessity of using gaseous hydrogen or steam as starting materials, as required in prior art processes.

  • Patent number: 4125735
    Abstract: A process for the synthesis of perfume products, Vitamin E and intermediates described herein involving a coupling reaction. For instance, a process for the synthesis of dehydrophytol and Vitamin E comprising forming a C.sub.15 acetylene from hexahydropseudoionone and then coupling said acetylene with 1-acetoxy-4-chloro-3-methylbut-2-ene to form a C.sub.20 acetoxy-enyne. The latter is readily subjected to partial hydrogenation and saponification in that order to form a dehydrophytol, a useful intermediate for the synthesis of Vitamin E and other products.
