摘要： A vinylpyridine resin that is hardly pulverized and thermally decomposed such that the degradation of the catalytic activity is suppressed while having a pore volume and a specific surface area to maintain a sufficient catalytic activity, and also a method of manufacturing the vinylpyridine resin are provided. The resin represents: a volume ratio of the pores having a diameter of 3 through 5 nm to all the pores of not less than 4% and not more than 60%; a total pore volume of not less than 0.15 cc/g and not more than 0.35 cc/g; and a specific surface area of not less than 20 m2/g and not more than 100 m2/g. The resin can be manufactured by using a poor solvent and not less than 50 wt % and not more than 90 wt % of a good solvent as porous agent.

摘要： According to a method for producing acetic acid by carbonylation of methanol characterized in that an acid having an acid dissociation constant (pKa) smaller than the constant of acetic acid is allowed to be present in the reaction system, acetic acid can be produced by the reaction of methanol and carbon monoxide in a reaction liquid in the presence of a solid catalyst containing rhodium and alkyl iodide, to achieve an enhanced reaction rate of carbonylation of methanol in producing acetic acid in the region at a high carbonylation degree (Ca>0.8 mol/mol) for more efficient production of acetic acid.
