Abstract：The ~1H chemical shift of ZnCl_2 aqueous solution has been measured by N.M.R.The hydration number of Zn~(2+)cation,equal to 3.8,was determined accordingto semi-empirical relationship between ~1H chemical shift,temperature T and concen-tration of ZnCl_2.The compositions of coordination compounds which are formedin TBP-CCl_4 extracting ZnCl_2 were studied by ~1H and ~(13)C N M R,as ZnCl_2·2TBP·2H_2O and ZnCl_2·2TBP.The phenomena of N.M.R.proved that part of waterreally combined with ZnCl_2 to form coordination in ZnCl_2-TBP-CCl_4-H_2O system. 收稿日期: 1985-02-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 俞斌 陈智 滕藤 沈其丰 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I2/81 1 Swift,T.J.;Sayre,W.G.,J.Chem.Phys.,44(1966) ,3567． 2 #12 3 #12 4 #12 5 Becker,E.D.,Spectrochim.Acta,17(1961) ,436． 6 Leonard,I.;Katzi,N.;Mason,G.W.;Peppard,D.F.,Spectrochim.Acta,34A(1978) ,51． 7 Giancotti,V.;Giordano,F.;Randaccio,L.;Ripamonti,A.,J.Chem.Soc.,(A),(1968) ,№3,757． No related articles found!
