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.
A mixture of 1.05 g (4 mmol) Cu(AcAc)2, 0.44 g (2 mmol) Zn(OAc)2, 0.38 g (2 mmol) SnCl2, and 20 ml OLA were added into a 100 ml three-neck round-bottom reaction flask connected to a nitrogen gas cylinder. The mixture solution was always stirred vigorously in the flask purged with high pure N2 gas (99.999%), during the whole synthesis. After heated at 130 C for 30 min, the mixture solution became brownish. The brownish solution was injected with 8 ml of sulfur – OLA solution (1 M), then heated at the reaction temperature T reaction 240-280 C for 1 h. When its color changed from dark brownish into blackish, the mixture solution (or product) was cooled down to room temperature (RT) and added with 15 ml of toluene for dispersing by sonication. To washing or purifying the product, 40 ml of ethanol was firstly added to let the nanoparticles flocculate and precipitate; then precipitates of nanoparticles were collected by centrifuging at 4000 rpm for 20 min and the supernatant liquid was removed; the collected precipitates were dispersed in toluene again by sonication; then ethanol was added for precipitates, new precipitates were collected again by centrifuging. The above process was repeated for three times. The final precipitates (or CZTS nanoparticles) were divided into two parts: (1) CZTS nanoparticles dispersed in toluene to form a stable ink solution and (2) CZTS power dried in a vacuum oven.
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.
