摘要： A chromatographic separator characterized in that two pumps are employed for controlling chromatographic separation that combines a first process for supplying at least one of feed solution and eluent into a circulation system and extracting the same quantity as that of liquid supplied into the circulation system from one position of a packed column where some component is enriched in the circulation system, and a second process for circulating liquid in the system without supplying the feed solution and eluent and extracting the separated component at all. Easy-to-control chromatographic separator, in which a total number of pumps to be used is decreased and high separation performance is attained through a simple structure, can thereby be provided.

摘要： A raw gas containing a gas component A with low affinity with an adsorbent and a gas component C with high affinity with the adsorbent are sequentially supplied to at least three adsorption columns, while a desorption gas containing a gas component D which differs from the gas components A and C is supplied to each of the adsorption columns other than the one to which the raw gas is being supplied. When the raw gas is supplied to the adsorption columns, the gas component A having lower affinity with the adsorbent exits the adsorption columns earlier than the gas component C having higher affinity. The gas components A and C can thus be separated from each other. When a gas including an enriched gas component A is discharged from the outlet of each adsorption column, the full amount is extracted out of the system. When a gas including an enriched gas component C is discharged from the outlet of each adsorption column, the full amount is extracted out of the system. When the gas mixture containing the gas components A and C is discharged from the exit of each adsorption column, all the discharged gas is fed back to the inlet of the adsorption column to which the raw gas is being supplied. It is possible to efficiently and sequentially separate the gas components A and C with this simple structure.

摘要： According to the present invention, heterocyclic copolymers comprising recurring units [A] and [B] having specific structures are obtained by hydrolyzing reaction products of diisocyanate compounds having specific structures with tolidine diisocyanate and hydrogen cyanide.The heterocyclic copolymers thus obtained are excellent in mechanical strength, heat resistance and solvent resistance.
