近来测定钛的很多工作与硫氰酸络合物的形式相联系着。当在钛-硫氰酸体系中引入有机碱,平衡将向着生成配位饱和的硫氰酸基络合物方面发展,并与有机碱的阳离子互相作用生成了很好的被萃取的络合盐: Ti(CNS)_6~(2-)+2HA~+(?)(HA)_2[Ti(CNS)_6]这类络盐的特点是在酸性溶液中有很高的稳定性,
A great deal of work on titanium has recently been linked to the form of thiocyanate complexes. When an organic base is introduced into a titanium-thiocyanate system, the balance will develop toward the formation of a coordinated saturated thiocyanate complex and with the cation of the organic base to produce well extracted complex salts : (CNS) _6 ~ (2 -) + 2HA ~ + (?) (HA) _2 [Ti (CNS) _6] These complex salts are characterized by high stability in acidic solution,
