苯并异噻唑啉酮(C_7H_5ONS)是一种不溶于水的白色针状晶体,易溶于二甲基甲酰胺(DMF)、乙二胺等有机溶剂中,是一种优良的防腐、防霉剂。该化合物的常规化学分析方法,目前尚未见文献报导。本文参考文献,提出了用非水酸碱滴定测定苯并异噻唑啉酮含量的分析方法,并对测定的条件进行了系统的研究。实验表明,以DMF为溶剂,锑-改良甘汞电极为电极对,用甲醇钠的苯-甲醇标准溶液进行电位滴定,终点电位突
Benzoisothiazolinone (C_7H_5ONS) is a water-insoluble white needle-shaped crystals, soluble in dimethylformamide (DMF), ethylenediamine and other organic solvents, is an excellent anti-corrosion, mold Agent. Conventional chemical analysis methods for this compound have not been reported in the literature yet. This paper references, proposed by non-aqueous acid-base titration benzothiazolone content analysis method, and the determination of the conditions of a systematic study. Experiments show that with DMF as solvent, antimony - modified calomel electrode as the electrode pair, with sodium methylate benzene - methanol standard solution potentiometric titration, the end potential of the sudden
