MTO级甲醇产品高锰酸钾时间分析方法的探讨

摘要

根据ASTM E 34-2003[1]、 ASTM D1363-2006[2]、 GB/T6324.3-2011[3]等工业甲醇的高锰酸钾试验标准，文章对甲醇产品锰酸钾时间分析方法进行了探讨。此分析的目的是确定一个观测数值或大概计算数值与相关国家技术规范的符合性，分析结果应修约到与技术规范限值的小数点保留位数相一致。此分析方法适用于在甲醇及MTO级中存在有能还原高锰酸甲杂质的测定。%According to the standards about Potassium Permanganate test and other industrial methanol, such as ASTM E 34-2003 , ASTM D1363-2006 , GB/T6324.3-2011 , etc., the method of methanol product potassium permanganate time analysis was discussed. The purpose of this analysis was to determine an observed or calculated values for the compliance relevant technical standards compliance. The results should be rounded to the right of the decimal point number was consistent with the specification limits. This method was suitable for testing methanol and MTO methanol in detection can restore a permanganate impurities.
