Formic acid is a kind of organic matter, chemical formula HCOOH, molecular weight 46.03, common name formic acid, is the simplest carboxylic acid. It is a colorless and pungent liquid. Formic acid is a weak electrolyte, but its aqueous solution is weakly acidic and corrosive, and can stimulate skin blistering. It is commonly found in the secretions of bees, certain ants, and caterpillars. It is an organic chemical raw material and is also used as a disinfectant and preservativeBasic Info.
University of Science and Technology of China professor and team developed a laser irradiation method to create a lattice distorted bismuth catalyst.
At the same time, they also developed a new electrolysis device, which successfully achieved the production of a high concentration of pure formic acid solution on a membrane electrode assembly equipped with a moisture and heat ventilation collection system, and can run continuously and stably for more than 300 hours.
That is, under the industrial current density of 200 macM-2, through 300 hours of continuous electrochemical carbon dioxide reduction reaction, high concentrations of formic acid can be produced.

Storage method
Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir shall not exceed 30℃, and the relative humidity shall not exceed 85%. Keep the container sealed. It should be stored separately from oxidizers, alkalis and active metal powders, and should not be mixed. Equipped with the corresponding variety and quantity of fire equipment. The storage area should be equipped with leak emergency treatment equipment and suitable containment materials. [4]
Transportation method
During railway transportation, the dangerous goods packing list in the Dangerous Goods Transportation Rules of the Ministry of Railways shall be strictly followed. The packing should be complete and the loading should be secure. During transportation, it is necessary to ensure that the container does not leak, collapse, fall or damage. It is strictly prohibited to mix with oxidants, alkalis, active metal powder, edible chemicals, etc. Transport vehicles should be equipped with the appropriate variety and quantity of fire equipment and leakage emergency treatment equipment. During transportation, it should be protected from sunlight, rain and high temperature. Road transport should follow the prescribed route, do not stay in residential areas and densely populated areas.
