Obtaining and composition of the substance

Formic acid (properties, use of the substance have been studied for a long time) is one of the first organic acids used by people to treat various diseases. The substance was used to make balms that relieve pain and improve well-being. In the XVII century. the English naturalist John Ray was the first to describe the colorless liquid that ants exuded when they sensed danger.Formic acid. Properties and application, why

The substance is released not only by ants, but also by bees. It also contains nettles and spruce needles. A small amount of acid is present in the composition of honey, raspberries, strawberries, strawberries, cherries.

A substance with the chemical formula HCOOH has another name - methanoic acid. It belongs to the carbon group. After the substance was discovered in nature, they learned to synthesize it in the laboratory from hydrocyanic acid. A little later, a technology for its production from carbon monoxide was developed.

In modern conditions, to obtain acid (food additive E236), the method of butane oxidation under the influence of high temperature is used. Also, the additive is synthesized by heating a mixture of oxalic acid and glycerin.
