2,4-二氨基甲苯及其同分异构体含量的快速测定
Rapid determination of 2,4-diaminotoluene and its isomers
摘要
Abstract
In order to avoid the interference of the non-banned isomers on the determination of 2,4-diaminotoluene, an effective ultra-high performance liquid chromatography ( UPLC) method was established. The spiked recoveries ranged from 63. 67% to 78. 90% while the relative standard deviation ( RSD) of precision experiments all registered less than 5%. Under the condition of signal to noise S/N =3 , the detection limit was 1. 0 , 0. 5 , 0. 5 and 1. 0 g/mL for 2,3-diaminotoluene, 2,4-diaminotoluene, 2,6-diaminotoluene and 3,4-diaminotoluene, respectively. Tests show that the proposed method is simple and rapid, only needing less than 5 minutes for the analysis procedure. This method is therefore reliable and accurate in quantity, and it also solves effectively the false positive problem in the analysis of 2,4-diaminotoluene.关键词
