以对甲基苯硫酚为原料，通过硝化、还原、重氮化等一系列反应合成4-甲基-2-羟基硫酚(A)。考察重氮化过程中NaNO_2的用量、硫酸浓度、反应温度以及水解时硫酸浓度对产率的影响。在最佳影响因素下得到最高产率71.2%。通过氯磺化、还原以及最佳反应条件合成含有邻羟基苯硫酚的螯合树脂(B)。使用傅里叶红外光谱表征4-甲基-2-羟基硫酚与螯合树脂。在废旧锂离子电池浸出液中进行分批实验考察4-甲基-2-羟基硫酚与螯合树脂的性能，并且使用HCl溶液提取所螯合的Co~(2+)。研究结果表明：螯合树脂显示良好的可循环性。

4-methyl-2-hydroxythiophenol(A) was synthesized by nitration, reduction and diazotization of p-thiophenol. The influence of dosage of NaNO2, concentration of sulfuric acid, temperature and concentration of H2SO4 in hydrolysis reaction on the yield of 4-methyl-2-hydroxythiophenol was studied. A high yield (71.2%) was achieved under the optimal reaction conditions. And a new chelating resin (B) containing o-hydroxythiophenol was synthesized through chlorosulfonation, reduction and the optimal reactions above. The FT-IR was used to identify the formation of 4-methyl-2-hydroxythiophenol and chelat...
