A team of scientists from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) transformed
During the experiment, chemists found thathighly efficient and selective oxidation of methane to HCOOH can be achieved in atomically dispersed regions of Fe (iron), limited by ZSM-5 channels. The conversion reaction took place at 80 ° C. This temperature fits into the concept of "soft conditions".
Scientists' work is paving the way for methane conversion under mild conditions.
While methane is one of the Earth's main greenhouse gases, along with carbon dioxide and ozone, formic acid has many uses.
Formic (methane) acid - chemicala reagent belonging to the first row of saturated monobasic acids of the carboxylic group. This acid under normal conditions is a colorless liquid with a peculiar pungent odor, which mixes well with diethyl alcohol, ethanol and water. It is soluble in media such as benzene, glycerin, toluene and acetone.
Formic acid is widely found naturally in free form in plants such as needles, nettles, in many fruits and in the pungent secretions of ants and bees.
Due to its unique molecularcomposition, formic acid has antibacterial properties, therefore, its main field of application is the food industry (additive E236) as an antibacterial preservative agent in the production of confectionery, canned and dairy products, soft drinks, and in the preparation of feed. Like tartaric acid, it is able to slow down the processes of decay and decay, therefore, silage and hay treated with it are better preserved. In the textile industry, this reagent is used in wool dyeing (bleaching agent), in leather tanning, as well as in beekeeping as a parasitic agent against ticks. In the chemical industry - as a solvent in chemical reactions.
This acid has gained a well-deserved place in medical practice.
Scientists have long faced the problem of utilizing methane, and a new way of converting it into formic acid under mild conditions will not only help the environment, but also industry.
