摘要
合成了对甲苯磺酸锰、邻甲苯磺酸锰、苯磺酸锰和甲烷磺酸锰4种磺酸锰盐。用热重和红外光谱分析方法对产物进行了表征。根据热重分析对4种无水磺酸锰盐的热稳定性进行了讨论,得出其热稳定性次序为:Mn(C6H5SO3)2>Mn(p-CH3C6H4SO3)2>Mn(CH3SO3)2>Mn(o-CH3C6H5SO3)2。红外分析结果表明,它们的分子结构不同。
The following manganese sulfonates have been prepared: Mn(p-CH_3C_6H_4SO_3)_2·6H_2O, Mn(C_6H_5SO_3)_2·6H_2O, Mn(o-CH_3C_6H_5SO_3)_2·5.5H_2O and Mn(CH_3SO_3)_2·_H_2O. They are characterized by TG and FTIR. The thermal stability of four anhydrous manganese sulfonates has been obtained according to TG analysis, and the sequence is Mn(C_6H_5SO_3)_2>Mn(p-CH_3C_6H_4SO_3)_2>Mn(CH_3SO_3)_2>Mn(o-CH_3C_6H_5SO_3)_2·IR analysis indicates that their crystal structures are different.
