CONSTITUTION:In carrying out an organic reaction using a solid acid catalyst, all or part of a reaction raw material is brought into contact with a solid acid catalyst (preferably strongly acidic cation exchange resin having <=1mm. particle size in spherical or crushed state, or highly acidic cation exchange fiber having <=100mu diameter) to do a gaseous-phase reaction not followed by distillation during the reaction. The reaction raw material after the liquid-phase reaction is subjected to a gas-liquid phase reaction followed by distillation during the reaction in the presence of a solid acid catalyst (preferably strongly acidic cation exchange fiber having <=100mu diameter). When the residue of the reaction raw material remains, it is brought into contact with part of the raw material of the liquid-phase reaction by the latter gas-liquid phase reaction in counter flow to carry out the organic reaction.
