oxidation number

The differential infrared spectrometry for determination of oxidation number and nitration number of oil products is an effective measure for monitoring the oxidation and nitration of automobile oil in the course of using.

根据差示红外光谱法原理 ,测定并记录在用油和新油在 185 0～ 15 5 0cm- 1的红外光谱图 ,运用计算机进行差谱分析处理 ,在差谱图中读取 185 0cm- 1和 172 0cm- 1及 16 30cm- 1处的吸收值 ,再根据基线法分别求出旧油中的氧化值和硝化值。
