    摘要： A cooling system which includes an occluding section for occluding vaporized cooling agent by means of an occluding agent so as to ensure continuous evaporation of cooling agent in the evaporating section. The system includes a high pressure and low pressure recovery sections for recovering the cooling agent from the occlusive agent by applying heat thereto. When a low potential energy is available, the occlusive agent is passed from the occluding section only to the low pressure recovery section, but when a high potential energy is to be used, it is passed through the high and low pressure recovery sections in this order.

    摘要： In the production step, alcohol is reacted with carbon monoxide in a reaction solvent in the presence of a rhodium-containing solid catalyst obtained by immobilizing rhodium in an insoluble carrier (I) containing a pyridine ring in its resin structure and an alkyl iodide containing an alkyl group of 1 to 5 carbon atoms, to produce a reaction product having a water content of 0.5 to 10% by weight; and in the subsequent removing step, an organic carboxylic acid is separated and recovered from the reaction product, and the recovered organic carboxylic acid is contacted with an insoluble carrier (II) containing a pyridine ring in its resin structure, to remove an iodide contained in the organic carboxylic acid.

    摘要： A methanol carbonylation catalyst includes a rhodium complex supported on a porous, cross-linked vinylpyridine resin, wherein the vinylpyridine resin has a cross-linking degree of 30-60%, a pore volume of 0.1-0.4 ml/g and an average pore diameter of 20-100 nm. The catalyst may be prepared by contacting the pyridine ring-containing resin with an aqueous solution containing rhodium ion and then contacting the resulting rhodium ion-carrying resin with carbon monoxide and an alkyl iodide in an organic solvent to convert the rhodium ion to a rhodium complex bound to the resin. Acetic acid is produced by reacting carbon monoxide with methanol at a temperature of 140.degree.-250.degree. C. and a partial pressure of carbon monoxide of 7-30 kg/cm.sup.2 in the presence of an alkyl iodide and the above catalyst.
