110-70-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. N1,N2-Dimethylethane-1,2-diamine, cas is 110-70-3,the chiral-nitrogen-ligands compound, it is a common compound, a new synthetic route is introduced below.
a 1,3-Dimethyl-2-(2-thienyl)-imidazolidine 23.5 g (267 mmol) of N,N’-dimethylethylenediamine were dissolved in 300 ml of toluene and treated with 29.8 g (266 mmol) of thiophene-2-carbaldehyde. The clear mixture was refluxed for 4 hours using a Dean-Stark trap. After that time 4.9 ml of water had separated in the trap. After cooling, the solution was filtered and evaporated. The oily residue was destined in vacuo. Yield: 45 g. Boiling point: 65 C. (0.1 mm Hg).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of N1,N2-Dimethylethane-1,2-diamine, 110-70-3
