亚甲基蓝两相返滴定法测定亚硫酸化油的磺化值

摘要

本文报导r以阴离子表面活性剂十二烷基硫酸钠作标准溶液，亚甲基蓝为指示剂，测定亚硫酸化油磺化值的两相返滴定法。实验表明：本法较亚甲基蓝指示剂两相直接滴定法简便、准确。%A reversed- titration method for determination of sulfonation value with methylene blue using the anionic surfactant sodium lauryl sulfate as the standardized titration solution has been described in this paper. The experiment which has been applied to the analysis of sulfited oil shows that the method is simple and accurate and the results are satisfactory.
