    • The invention concerns a method for preparing polyazacycloalkanes immobilised on a silica gel from a polyazacycloalkane of formula (A) in which: R1 and R2 represent a hydrogen atom, an alkyl radical, or a [hetero(aryl)]alkyl radical; W1, W2 and W3 represent a radical of formula (B): —[(CT1T2)n—[N(R3)]p—(CT3T4)m]l— such as defined in the description; R3 represents a hydrogen atom, an alkyl radical or a [hetero(aryl)]alkyl radical, provided that the polyazacycloalkane ring of the compound of formula (A) comprises not more than 30 cyclic carbon atoms, and not more than 6 cyclic nitrogen atoms. The invention is characterised in that: (a) the compound of formula (A) is reacted with a compound of formula (C): Z—R4—Si(X1)(X2)(X3), such as defined in the description to form a compound of formula (D); (b) said compound of formula (D) is condensed on the silanol sites of a silica gel to form the immobilised polyazacycloalkane of formula (E); and (c) some ethanol sites having not reacted are, if required, protected by Z′, a group protecting the hydroxyl function. The invention is useful for separating oxygen from air.
    • 本发明涉及一种由式(A)的多氮杂环烷固定在硅胶上的多氮杂环烷烃的方法,其中:R1和R2表示氢原子,烷基或[杂(芳基)]烷基; W1,W2和W3表示式(B)的基团: - [(CT1T2)n- [N(R3)] p-(CT3T4)m] -1-如描述中所定义; R 3表示氢原子,烷基或[杂(芳基)]烷基,条件是式(A)化合物的多氮杂环烷烃环包含不多于30个环状碳原子,并且不超过6个环状氮原子 。 本发明的特征在于:(a)式(A)化合物与式(C)化合物:Z-R 4 -Si(X 1)(X 2)(X 3) 形成式(D)的化合物; (b)所述式(D)化合物在硅胶的硅烷醇位上缩合形成式(E)的固定化的多氮杂环烷烃; 和(c)如果需要,一些没有反应的乙醇部位被保护羟基官能团的Z'保护。 本发明可用于从空气中分离氧气。
