13395-16-9, 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. Bis(acetylacetone)copper, cas is 13395-16-9,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.

General procedure: In a typical synthesis of Cu40Ag60, 0.45mmol Cu(acac)2 and 0.35 Ag (ac) was mixed with 3mL of OAm, 1 mL of OAc and 11mL of ODE. All synthesis was conducted in a four-necked glass reactor allowing the precise temperature control and inert gas atmosphere under dark conditions. Firstly, the mixture was heated to 60C and kept at this temperature for 10min. Then, the mixture was heated to 180C and kept at this temperature for 30min before it was cooled down to room temperature. After cooling, the resultant reaction mixture was collected with hexane (2mL) and the NPs were separated by centrifugation (8500rpm, 12min) after adding isopropanol (40mL). To further purify the yielded CuAg NPs, the product was centrifuged (8500rpm, 12min) one more time with ethanol (40mL). Finally, the remaining product was dispersed in hexane (10mL) for further use. By using the same recipe and varying metal precursor amounts, two different compositions of CuAg NPs were synthesized. Reductive mixing of 0.3mmol Cu(acac)2 and 0.5 Ag(ac) resulted in Cu30Ag70 NPs and mixing 0.6mmol Cu(acac)2 with 0.4 Ag (ac) led to Cu60Ag40. Synthesis of Ag NPs was conducted with the same recipe without using Cu precursor.

The chemical industry reduces the impact on the environment during synthesis,13395-16-9,Bis(acetylacetone)copper,I believe this compound will play a more active role in future production and life.
