A catalyst and a method for preparing S-indoxacarb using the catalyst. The catalyst is prepared using 3-tert-butyl-5-(chloromethyl)salicylaldehyde and cyclohexanediamine as raw materials, where an original quinine catalyst such as cinchonine is replaced with the catalyst for application in the asymmetric synthesis of tert-butyl hydroperoxide and 5-chloro-2-methoxycarbonyl-1-indanone ester, greatly improving selection in the asymmetric synthesis process, with the S-enantiomer content increasing from 75% to over 98%, achieving the recycling of a high-efficiency chiral catalyst, and greatly reducing production costs. The synthesis process of the catalyst is simple and is favorable for industrialization, and lays good foundations for the production of high-quality indoxacarb.

An amine-functionalized, crosslinked porous copolymer can be synthesized by linking 1,4-benzenediamine and pyrrole with p-formaldehyde in the presence of concentrated hydrochloric acid catalyst. The polymer is permanently microporous, with a BET surface area of 250 to 350 m.sup.2/g. Due to the high concentration of polar amines within its backbone, the polymer exhibits a CO.sub.2 uptake of 17.5 to 30 cm3/g at 298 K and 1 bar, but demonstrated a remarkably high selectivity for CO.sub.2 over N.sub.2 at 298 K. Dynamic breakthrough experiments indicate that this material is an effective adsorbent for selectively separating CO.sub.2 from a dry and wet gas mixture containing N.sub.2 for over 45 cycles without significant loss of performance. Furthermore, the polymer can be regenerated at room temperature after each cycle by a simple N.sub.2 flow.

The method includes mixing an aldehyde and a first solvent to form a mixture. The method further includes mixing an organosulfur phenol and an aromatic compound to the mixture to form a phenol mixture and heating the phenol mixture in the presence of an acid to form a solid. The solid is dried to obtain the cross-linked porous polymer. The obtained cross-linked porous polymer has repeat pyrrole units bonded to one another, and the cross-linked porous polymer has a thiol group which separates non-adjacent pyrrole units. The cross-linked porous polymer obtained after drying is in a form of solid particles having a spherical particle structure.
