Abstract
A new preparative route to short-chain aliphatic alcohols has been dev eloped where the products, optionally based upon syngas feedstock, are useful as octane boosters or may be used directly as basic chemical p roducts. Within definite CO/MeOH and H-2/CO mole ratios by carbonylati ng methanol at 210 bar and 180 degrees C in the presence of polymer-su pported rhodium catalysts and an iodide-containing promoter the princi pal product acids are the acetic, propionic, butyric, valeric and hexa noic. These fractions may be converted to corresponding esters by a tr ansesterification reaction and finally to alcohols by hydrogenolysis.
