Title:
HIGH MOLECULAR WEIGHT CARBONYL GROUP-CONTAINING SUBSTANCE USEFUL AS ABSORBENT FOR NITROGEN COMPOUND
Document Type and Number:
Japanese Patent JPS59182802
Kind Code:
A
Abstract:
A carbonyl groups containing macromolecular material which is suitable for use as a sorbent for ammonia, urea or amino compounds. It contains structural units having 3 or more, optionally hydrated vicinal carbonyl groups, preferably keto groups, the C-atoms of which may form part of a ring structure. Particularly, the ring structure contains 5-7 C-atoms, and at least2 ring atoms may form part of an aromatic ring system. The starting material used may be made of a polymer of the same type as that used in the manufacture of ion exchange resins. The carbonyl groups containing unit may form part of an independent compound, e.g., ninhydrin which may be physically bonded to the macromolecular material, but is preferably covalently bonded thereto.
