作者曾经报道过:3,6-二硝基二苯并碘六圜盐(Ⅰ)以及3,6-二硝基-9-对硝基苯二苯并碘六圜盐(Ⅱ)等与碱作用后生成鲜明的有色物质。这些有色物质的溶解度性质与碘盐迴异。有色物质易溶于乙酸乙酯、吡啶、四氢呋喃、二氯甲烷等有机溶剂中,而碘杂环盐(Ⅰ)、(Ⅱ)等则表现盐类的典型溶解度性质,一般难溶于有机溶剂而溶于热甲酸、热水中。测定了碘杂环(Ⅰ)和(Ⅱ)硫氰酸盐(X~-=SCN~-)在吡啶中的紫外-可见光谱,表明碘
The authors have reported that 3,6-dinitrobenzodiphenyl iodonium hexachloride (I) and 3,6-dinitro-9-p-nitrobenzodiphenyl iodonium hexahydrate (II) and the like and alkali After the formation of a clear colored material effect. The solubility of these colored materials is different from that of iodized salt. Color materials are easily soluble in organic solvents such as ethyl acetate, pyridine, tetrahydrofuran, methylene chloride, etc. The typical solubility properties of iodine heterocyclic salts (Ⅰ, Ⅱ) are generally poorly soluble in organic solvents Soluble in hot acid, hot water. The UV-Vis spectra of iodine heterocycles (Ⅰ) and (Ⅱ) thiocyanate (X ~ - = SCN ~ -) in pyridine were determined, indicating that iodine
