FIELD: chemistry.
SUBSTANCE: described is a carbonylation method for producing a carbonylation product by bringing carbon monoxide into contact with initial material containing alcohol and/or its reactive derivative, in vapour phase using a heterogeneous heteropolyacid catalyst containing one or more metal cations selected from Cu, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and Pt. The initial material contains 0.5-20 wt % water and water in the initial material is fresh and/or recycled.
EFFECT: increased catalyst activity, increased degree of convertion of methanol into the desired product.
