Synthetic Route of 21436-03-3, An article , which mentions 21436-03-3, molecular formula is C6H14N2. The compound – (1S,2S)-Cyclohexane-1,2-diamine played an important role in people’s production and life.
A new chiral separation system effective for the enantioselective extraction of racemic trans-cyclohexane-1,2-diamine is presented. Enantioselective dispersive liquid?liquid microextraction has been used for the chiral microseparation of trans-cyclohexane-1,2-diamine, with a chiral azophenolic crown ether being identified as a versatile chiral selector. The influence of various process conditions on the extraction performance was studied experimentally. It was found that the operational selectivity in one extraction step is mainly related to the type and volume of the solvents, chiral selector concentration, extraction time, temperature of sample solution, and pH. At optimum conditions (300 muL of diethyl ether as the extraction solvent 1 mL of methanol as the disperser solvent, with 5 mmol L?1 chiral selector concentration, pH of the sample equal to 4.5, 30 min extraction time and a temperature of 10 C), the distribution ratio of (R,R)- and (S,S)-trans-cyclohexane-1,2-diamine was 18.3 and 1.8, respectively, while the enantioselectivity value of 10.2 was found at the optimum condition.
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., Synthetic Route of 21436-03-3
