The field of research related to CO2 capture is significant and really attractive for sustainable green chemistry. Focusing attention on this topic in our research led to obtaining new compounds based on diamines. As a result of the syntheses carried out using aqueous solutions of diamines exposed to the slow action of carbon dioxide from the air, three new monocarbamates were obtained. X-ray powder diffraction data for the obtained compounds: 12-propCO2 (C4H10N2O2) [a = 9.3033(7), b = 9.2485(7), c = 7.4735(7) Å, β = 111.214(7)°, V = 599.46 Å3, Z = 4, space group Ia]; 13-propCO2 (C4H10N2O2) [a = 5.0065(10), b = 12.2093(23), c = 4.9006(10) Å, β = 96.457(18)°, V = 297.65 Å3, Z = 2, space group P21]; and 13-dytekCO2 (C6H14N2O2) [a = 28.374(3), c = 5.1726(9) Å, V = 3606.53 Å3, Z = 18, space group $R\bar{3}$] are reported in this paper.

与CO 2捕获相关的研究领域对于可持续绿色化学来说意义重大且极具吸引力。我们的研究重点关注这一主题，从而获得了基于二胺的新化合物。由于使用暴露于空气中二氧化碳缓慢作用的二胺水溶液进行合成，获得了三种新的单氨基甲酸酯。所得化合物的X射线粉末衍射数据：12-propCO 2 (C 4 H 10 N 2 O 2 ) [ a = 9.3033(7), b = 9.2485(7), c = 7.4735(7) Å , β = 111.214(7) ° , V = 599.46 Å 3 , Z = 4 , 空间群Ia ]; 13-propCO 2 (C 4 H 10 N 2 O 2 ) [ a = 5.0065(10), b = 12.2093(23), c = 4.9006(10) Å , β = 96.457(18) ° , V = 297.65 Å 3 , Z = 2,空间群P 2 1 ];和13-dytekCO 2 (C 6 H 14 N 2 O 2 ) [ a = 28.374(3), c = 5.1726(9) Å , V = 3606.53 Å 3 , Z = 18,空间群$R\bar{3} $ ] 已在本文中报道。
