ABSTRACT:
A process for producing C.sub.3 -C.sub.20 aliphatic alcohols which comprises reacting carbon monoxide, hydrogen and acetylene, on a fused iron catalyst, in the form of a solution in a liquid medium inert to said reagents and said iron catalyst being present in this medium.
As the liquid medium use is made of a fraction of aliphatic saturated C.sub.10 -C.sub.18 alcohols or a fraction of C.sub.12 -C.sub.20 paraffin hydrocarbons, or a mixture thereof. The synthesis is conducted at a temperature ranging from 170.degree. to 220.degree. C under a pressure of from 20 to 200 atm.
The process according to the present invention makes it possible to increase concentration of acetylene in the reaction medium, whereby the catalyst space-time yield is increased. Moreover, the present invention enables a longer stable service life of the catalyst owing to the isothermal character of the catalyst bed and higher thermal stability of the process.
