    摘要: By reacting, using as a catalyst a modified or unmodified cyclodextrin, a phenol compound with a haloform in the presence of an alkali metal hydroxide, while maintaining the molar ratio of the cyclodextrin to the haloform at 0.5 to 10, a substituent group derived from the haloform can be introduced to the para-position of the phenol compound with high selectivity, whereby useful para-substituted phenol derivatives can be advantageously obtained.

In this process carbon monoxide contained in the gas mixture containing carbon monoxide and up to approximately 40,000 ppm of water can be effectively separated by contacting the gas mixture with an absorbing solution containing (a) at least one copper(I) halide, (b) at least one aluminum(III) halide and (c) at least one compound having at least two benzene nuclei in one molecule thereof. The component (c) is selected from the group consisting of (A) the compounds having the general formula (I): ##STR1## wherein R.sub.1 is hydrogen or an alkyl group, R.sub.2 and R.sub.3 are independently hydrogen, an alkyl group, or an aryl group, i is 0, 1, 2, 3, or 4, and m and n are independently 0, 1, 2, or 3, (B) the oligomers styrene or the derivatives thereof, (C) the polymers of styrene or the derivatives thereof and (D) copolymers of (i) styrene or the derivatives thereof and (ii) ethylene or the derivatives thereof and, optionally, an aromatic solvent, without causing the decrease in the carbon monoxide absorbing and releasing capacities of the absorbing solution.

    摘要: With application of new liquid absorbent, comprised of a compound selected from a group composed of silver halide and cuprous halide, an aluminium halide, a polymer selected from a group composed of styrene and styrene derivatives, and an aromatic hydrocarbon, it is possible to recover ethylene by absorbing ethylene from gaseous mixture containing ethylene such as FCC off gas, ethylene plant off gas and coke oven gas. In particular, said liquid absorbent is neither diluted nor reduced its capability to absorb ethylene by water or its vapor contained in the said gaseous mixture, so the liquid absorbent can be used repeatedly for the recovery of ethylene from gaseous mixture containing ethylene and water or its vapor, without any pretreatment to reduce the water content of said gaseous mixture.

    摘要: A solid form adsorbent of carbon monoxide, that is obtained by the process including the following steps. First, copper salts or copper oxide is stirred in a solvent. Then, into the solution or suspension thus obtained, active carbon is added. Finally, the solvent is removed by means of pressure reduction, distillation, etc. The carbon monoxide adsorbent produced according to this invention adsorbs carbon monoxide rapidly when it is brought into contact with a mixed gas. The adsorbed carbon monoxide can be readily separated and discharged through either heating the carbon monoxide adsorbent to above 60.degree. C. or reducing the partial pressure of carbon monoxide. The carbon monoxide obtained in accordance with the present invention is stable relative to the water content in the mixed gas, and it is capable of separating carbon monoxide directly from the mixed gas containing the water. Also, the separated carbon monoxide does not contain the vapor of the solvent from the carbon monoxide adsorbent. Therefore, it is not necessary to provide equipment to collect the solvent vapor. Furthermore, this carbon monoxide adsorbent does not produce corrosive gases, etc. The carbon monoxide adsorbent obtained by using copper (II) salts or copper (II) oxide is also stable relative to sulfur content in the mixed gas.
