Abstract
A continuous vapor phase processes for direct condensation of methanol and/or dimethyl ether with dilute acetylene feedstream to a mixture containing at least one higher molecular weight alkanol, such as n-propanol or isobutanol, over an alkaline catalyst which is, advantageously, an essentially magnesium oxide catalyst.
Claims17
A continuous vapor phase process for direct catalytic conversion of methanol in combination with dilute acetylene-containing feedstream to at least one higher molecular weight alcohol which comprises contacting the dilute acetylene-containing feedstream and methanol in the vapor phase with a catalyst which is magnesium oxide admixed with a diluent under condensation conditions to form a mixture containing at least one higher molecular weight alcohol.
A continuous vapor phase process for direct catalytic conversion of methanol in combination with dilute acetylene-containing feedstream to at least one higher molecular weight alcohol which comprises contacting the dilute acetylene-containing feedstream and methanol in the vapor phase with a catalyst which is magnesium oxide admixed with a diluent and containing a low loading of an oxide selected from the group consisting of aluminum, zinc and zirconium oxides, under condensation conditions to form a mixture containing at least one higher molecular weight alcohol.
