    Abstract: PURPOSE: A new method using isomerization reaction in the presence of strong acid is proposed to obtain substantial industrial profits. The method somewhat contributes to the enhancement of the reaction activity, but should use additional compound thus cannot be simplified. CONSTITUTION: A producing method of the invention is performed in the presence of catalyst system including methyl formate, water, solvent and 1 or more halogenation accelerator and 1 or more Ir compound. The method maintains the partial pressure of CO somewhat constantly during the reaction and maintains the amount of polyformate less than 20wt% of reacting medium.
