21436-03-3. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine. In a document type is Article, introducing its new discovery.
Determination of organic amine in waste water from 1, 6-hexanediamine production by pre-column derivatization and ultra-high performance liquid chromatography method
A pre-column derivatization method was established for determination of organic amine by ultra-high performance liquid chromatography(UPLC) in waste water from 1, 6-hexanediamine production. The chromatographic conditions were optimized. The standard curve was plotted and the actual sample was calibrated accordingly. The results showed good linear relationships between peak area and concentration of 1, 6-hexanediamine, cis-1, 2-diaminocyclohexane and trans-1, 2-diaminocyclohexane in the range of 1. 14-228. 40, 2. 02-201. 5 and 2. 13-193. 64 mg/L, respectively. The coefficients of correlation was 0. 998 9, 0. 999 1 and 0. 999 5, respectively. The detection limits were around 0. 33-0. 61 mg/L. The limits of quantification were around 1. 10-2. 03 mg/L. The recoveries were in the range from 95. 1% to 105. 6 %. The relative standard deviations were within 2. 1% (n=6). This method is highly efficient and sensitive, and is an effective method for determining the main organic amines in 1, 6-hexanediamine diamine production wastewater.
21436-03-3, I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21436-03-3, help many people in the next few years.
