    • The invention provides a metathetic process of the type M'X + M"Y = M'Y + M"X, where M' differs from M" and the reagents and the products are water-soluble salts, comprising the steps of (a) transferring a solution of M"Y through at least one column containing cation exchanger beads loaded with M' cations, obtained in step (b) hereinafter, whereby cation exchange takes place to form a solution of M'Y and cation exchanger beads loaded with M", and (b) transferring a solution of M'X through said column containing cation exchanger beads loaded with M" obtained in step (a) above, whereby cation exchange takes place to form a solution of M"X and cation exchanger beads loaded with M'; characterized in that both M' and M" are selected from the group consisting of sodium, potassium and ammonium; X and Y are different anions; two types of cation exchanger, A and B, are used in the process; cation exchanger A is more acidic than cation exchanger B; in step (a), the solution of M"Y is first transferred through beads of cation exchanger A and then through beads of cation exchanger B, both of which are loaded with M' cations obtained in step (b), whereby cation exchange takes place on both cation exchangers to form a solution of M'Y and to form cation exchanger beads loaded with M"; and in step (b), the solution of M'X is first transferred through beads of cation exchanger B and then through beads of cation exchanger A, both of which are loaded with M" cations obtained in step (a), whereby cation exchange takes place on both cation exchangers to form a solution of M"X and to form cation exchanger beads loaded with M'.
    • 本发明提供M'X + M“Y = M'Y + M”X型的复分解方法,其中M'不同于M“,试剂和产物是水溶性盐,包括以下步骤:(a )将M“Y溶液通过至少一个含有阳离子交换剂珠的负载有M'阳离子的柱,在步骤(b)中获得的阳离子交换发生在步骤(b)中,由此进行阳离子交换以形成M'Y和阳离子交换剂珠的溶液, M“,(b)通过上述步骤(a)中得到的载有M”的载有阳离子交换剂珠的M'X的溶液转移,由此进行阳离子交换以形成M“X和阳离子交换剂珠的溶液 负载M';其特征在于M'和M“均选自钠,钾和铵; X和Y是不同的阴离子; 在这个过程中使用两种类型的阳离子交换剂A和B; 阳离子交换剂A比阳离子交换剂B更酸性; 在步骤(a)中,首先通过阳离子交换剂A的珠粒转移M“Y的溶液,然后通过阳离子交换剂B的珠子,两者都装载步骤(b)中获得的M'阳离子,由此阳离子交换 置于两个阳离子交换剂上以形成M'Y的溶液并形成负载有M“的阳离子交换剂珠; 在步骤(b)中,首先将M'X的溶液通过阳离子交换剂B的珠粒转移,然后通过阳离子交换剂A的珠粒,两者都载有步骤(a)中得到的M“阳离子,由此阳离子交换 发生在两个阳离子交换剂上以形成M“X的溶液并形成负载有M'的阳离子交换剂珠粒。
