n
x
A
y−
where
B is a cation comprising at least one nitrogen atom,
A is an anion and
n is an integer from 1 to 3,
x and y are each an integer from 1 to 3 and the product of x and y is equal to n,
by reacting salts of the formula II
(B

)
n
x
A
y−
where B and n, x and y are as defined above and C is a compound which has one or more carboxylate groups (referred to as carboxylate for short) and is different from A,
with the ammonium salt of the anion A or with the protic acid of the anion A in the presence of ammonia.
制备I(B+)nxAy的盐的过程-其中B是至少含有一个氮原子的阳离子,A是阴离子,n是1到3的整数,x和y分别是1到3的整数,且x和y的乘积等于n,通过反应II(B+)nxAy的盐来实现-其中B和n、x和y如上定义,C是一种具有一个或多个
羧酸基团(简称为
羧酸)且与A不同的化合物,与阴离子A的
铵盐或其质子酸在
氨的存在下反应。
