Researchers have developed a brand-new, more secure, and more cost-effective technique for producing acetone utilizing light and a photoactive iron chloride catalyst, simplifying the procedure and lowering the need for high-temperature, high-pressure actions. This innovation might change acetone production by utilizing sunlight and scaling up for industrial use, promising improved safety and sustainability.
Acetone, an essential input for the chemical industry, is generally manufactured through a complex and dangerous procedure. Scientists from Brazil and Germany have actually collectively created a more environment-friendly technique.
Acetone plays an essential function in the chemical market, serving as a vital part in the creation of diverse items consisting of adhesives, antibiotics, electronic parts, solvents, paint inks, vitamins, and removers. Its production is harmful and complicated. To simplify the process and make it more secure and less expensive, researchers in Brazil and Germany have actually developed an innovative method that utilizes only light and photoactive iron chloride (FeCl3), an economical chemical compound.
An article on the research study, which was funded by FAPESP, was just recently released in the journal ACS Catalysis.
The basic acetone manufacturing process, understood as the Hock or cumene process, consists of a number of stages. Gas, a petroleum item, is transformed to propylene, an extremely flammable gas, which is responded with benzene and after that with oxygen at high temperature levels and pressures to generate acetone. These responses also produce phenol, a compound for which there is less need but which can be transformed to value-added substances, although this is pricey.
The option method developed by scientists associated with the Federal University of São Carlos (UFSCar) and the Federal University of Minas Gerais (UFMG) in Brazil, in partnership with coworkers at limit Planck Institute of Colloids and Interfaces in Germany, is based on lp oxidation and a photocatalytic response utilizing iron chloride as an uniform catalyst in the existence of light.

, offering increase to a radical that leads in the presence of oxygen to the development of acetone,” stated Ivo Freitas Teixeira, a teacher in UFSCars Department of Chemistry and last author of the article. “We accomplished an extremely essential reaction in an absolutely various way and utilizing very simple aspects.”
Evidence that the reaction was truly driven by chlorine radicals produced by Fe-Cl photolysis was gotten by ways of mechanistic research studies, consisting of mass spectrometry, an analytical strategy that determines the elements of a mix by identifying the molecular weight of their particles.
Amongst the benefits of the procedure is the fact that it is direct– skipping the production of propylene in intermediate phases– and much safer as it does not include oxygen responses at high temperature levels and pressures or flammable and dangerous intermediaries. In addition, it lowers energy consumption and expense because it has less stages and occurs at space temperature level (25 ° C).
The experiments utilized light-emitting diodes (LEDs) as a source of light, however the scientists prepare to utilize sunshine instead in the future, making the approach a lot more sustainable.
Patent application and next steps
A patent application has actually been filed with the National Industrial Property Institute (INPI), Brazils patent workplace, and collaborations with companies are being sought to scale up and commercialize the new process. “It could end up being absolutely disruptive for acetone production in the chemical industry, enhancing safety and sustainability, and leading the way to direct production of acetone, which would increase and cut expenses competitiveness,” Teixeira stated.
The main challenges, he added, are the big scale of processes in the petrochemical market, and the reality that yet there are no industrial photocatalysis techniques.
The research also continues to establish in 2 directions: testing of the brand-new method with other compounds, such as methane; and seeking ways to scale up the procedure so as to increase commercial production and yield.
