摘要
用pH滴定法测得正辛基异羟肟酸n-C_7H_(15)CONHOH,α,ω—癸基二异羟肟酸α.ω—(CH_2)_(?)(CONHOH)_2及对苯二异羟肟酸p-C_(6)H_4(CONHOH)_2在30.0℃,0.1mol·1^(-1)NaCl水溶液中的酸解离常数;制得这三种螯合剂与W(Ⅵ)摩尔配比依次为2:1、1:1及1:2的固体配合物;研究了它们的化学组成、溶解度、摩尔电导、热谱及红外光谱,对不同配合物的配位方式作出讨论.
The dissociation constants of three hydroxamic acids n-C7H15CONHOH,α,ω-(CH2)5-(CONHOH)2, p-C6H4(CONHOH)2 in aqueous solution were pH-metrically determined in the presence of 0.1 mol · l-1NaCl at 30. 0± 0.1℃ . The three new solid complexes of tungsten (Ⅵ)-hydroxamates WO2(n-C7H15CONHO)2, WO2[α,ω-(CH2)l(CONHO)2], W2O5-[p-C6H4(CONHO)2] · 2H2O were synthesized and characterized by ekmental analysis, solubility ,molar conductance, infrared spectra and thermogravimetric studies.
