摘要： An aqueous dispersion of polyamide rubber elastic body, which contains an aqueous medium and a polyamide rubber elastic body emulsified and dispersed in the aqueous medium in the presence of a surfactant. The surfactant is used in an amount of 1 to 20 parts by weight based on 100 parts by weight of the polyamide rubber elastic body, and is for example at least one member selected from the group consisting of a polyoxyalkylene alkyl ether sulfate, a dialkyl sulfosuccinate, a fatty acid salt and an ethylene oxide/propylene oxide copolymer. This aqueous dispersion can produce a molded article having the characteristics of the polyamide rubber elastic body, particularly a molded article which hardly suffers frombleeding of the surfactant and is excellent in transparency.

摘要： A nitrogen oxide purifying apparatus includes a gas absorption vessel (1) and a condenser (6), where the vessel receives an absorption solution containing liquefied N 2 O 4 for absorbing NO and also receives a source gas to vary the temperature and/or pressure of the source gas and the absorption solution, while the condenser receives a gas from the gas absorption vessel (1) to vary the temperature and/or pressure of the gas. In the gas absorption vessel (1), the absorption solution containing liquefied N 2 O 4 may be applied to the source gas containing NO, so that NO is absorbed in the absorption solution. Then the absorption solution is heated and/or depressurized to generate an intermediate gas containing a relatively large amount of NO and a smaller amount of NO 2 from the absorption solution. In the condenser (6), the intermediate gas is cooled and/or pressurized to give condensed N 2 O 3 and/or condensed N 2 O 4 .
