Product Description
HCOOH is the chemical name for formic acid, also known as anthranilic acid. Formic acid is colourless and has a pungent odour and is corrosive, blistering and reddening human skin on contact. It has a melting point of 8.4℃ and a boiling point of 100.8℃. Due to the special structure of formic acid, one hydrogen atom of formic acid and carboxyl group are directly connected, which can also be regarded as a hydroxyl formaldehyde. Therefore formic acid has both acid and aldehyde and properties.
Basic Information
Physicochemical properties
Flammable. It is freely miscible with water, ethanol, ether and glycerol, miscible with most polar organic solvents, and has certain solubility in hydrocarbons.
Relative density (d204) 1.220. Refractive index
1.3714. The combustion heat is 254.4 kJ/mol, the critical temperature is 306.8 ℃, and the critical pressure is 8.63 MPa. Flash point 68.9 ℃ (open cup). The density is 1.22, the relative vapor density is 1.59 (air=1), and the saturated vapor pressure (24°C) is 5.33 kPa.
High concentrations of formic acid are easy to freeze in winter.
Incompatible materials: strong oxidants, strong bases, active metal powders.
Hazardous characteristics: its vapor and air form an explosive mixture, which can cause combustion and explosion in case of open fire and high heat energy. Reacts with strong oxidants.
Solubility: miscible with water, insoluble in hydrocarbons, miscible in alcohol.
In hydrocarbons and in the gaseous state, formic acid occurs as a dimer through hydrogen bonding. In the gaseous state, hydrogen bonding results in a large deviation between the equation of state for formic acid gas and the ideal gas. Liquid and solid formic acid consists of continuous formic acid molecules that are hydrogen-bonded together.
Formic acid is decomposed into CO and H2O under the catalysis of concentrated sulfuric acid:
Due to the special structure of formic acid, one of its hydrogen atoms is directly connected to the carboxyl group. It can also be regarded as a hydroxy formaldehyde. So formic acid has both acid and aldehyde properties.
Formic acid has the same properties as most other carboxylic acids, although normally it does not form acid chlorides or anhydrides. Formic acid is dehydrated and decomposed into carbon monoxide and water. Formic acid has reducibility similar to aldehydes. It can have a silver mirror reaction, reducing the silver ions in the silver ammine ions to metallic silver, and being oxidized into carbon dioxide and water:
Formic acid is the only carboxylic acid that can undergo an addition reaction with olefins. Under the action of acid (such as sulfuric acid, hydrofluoric acid), formic acid rapidly reacts with olefin to form formate. But a side reaction similar to the Koch reaction also occurs, and the products are higher carboxylic acids.
Logarithmic value of octanol/water partition coefficient: -0.54, upper explosion limit % (V/V): 57.0, lower explosion limit % (V/V): 18.0.
Formic acid is a strong reducing agent and can produce silver mirror reaction. Among the saturated fatty acids, the acidity is the strongest, and the dissociation constant is 2.1×10-4. Slowly decomposes into carbon monoxide and water at room temperature. It is heated to 60~80℃ with concentrated sulfuric acid to decompose and release carbon monoxide. Formic acid is decomposed to release carbon dioxide and hydrogen when heated to above 160°C. Alkali metal salts of formic acid are heated to 400°C to form oxalates.
Main application
Formic acid is one of the basic organic chemical raw materials and is widely used in industries such as pesticides, leather, dyes, medicine and rubber. Formic acid can be directly used in fabric processing, tanning, textile printing and dyeing and storage of green fodder, and can also be used as metal surface treatment agent, rubber auxiliary and industrial solvent. In organic synthesis, it is used to synthesize various formate esters, acridine dyes and formamide series pharmaceutical intermediates. The specific categories are as follows:
Pharmaceutical industry: caffeine, analgin, aminopyrine, aminophylline, theobromine borneol, vitamin B1, metronidazole, mebendazole.
1. Pesticide industry: triazolone, triazolone, tricyclazole, triazole, triazophos, paclobutrazol, dinoconazole, insecticide, dicofol, etc.
2. Chemical industry: calcium formate, sodium formate, ammonium formate, potassium formate, ethyl formate, barium formate, dimethylformamide, formamide, rubber antioxidant, pentaerythritol, neopentyl glycol, epoxy soybean oil, epoxy Octyl soybean oleate, pivaloyl chloride, paint remover, phenolic resin, pickling steel plate, etc.
3. Leather industry: tanning agents, deliming agents and neutralizing agents for leather.
4. Rubber industry: natural rubber coagulant.
5. Others: It can also manufacture printing and dyeing mordants, dyeing agents for fibers and paper, processing agents, plasticizers, food preservation and animal feed additives.
6. Preparation of CO. Chemical formula: HCOOH=(concentrated H2SO4 catalysis) heating=CO+H2O
7. Reducing agent. Determination of arsenic, bismuth, aluminum, copper, gold, indium, iron, lead, manganese, mercury, molybdenum, silver and zinc. Determines cerium, rhenium and tungsten. Check for aromatic primary and secondary amines. Determination of relative molecular mass and solvent for crystallization. Determination of methoxy. Used as a fixative in microscopic analysis. Manufacture of formates.
8. Formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts, and the generated formate can be dissolved in water, so it can be used as a chemical cleaning agent. Formic acid does not contain chloride ions and can be used for cleaning equipment containing stainless steel materials.
