Ⅰ. What is Formic Acid? From Physical Properties to Chemical Characteristics
Formic acid, commonly known as methanoic acid, is the simplest carboxylic acid with the chemical formula HCOOH. It is a colorless, fuming liquid with a pungent odor, found in the secretions of ants, bees, and caterpillars.
Basic Physicochemical Properties of Formic Acid:
Melting point: 8.2-8.4°C
Boiling point: 100-101°C
Density: 1.22 g/mL (25°C)
Acidity: Stronger than other carboxylic acids in its homologous series, because its carboxyl group is directly bonded to a hydrogen atom.
Unique Properties: Exhibits dual characteristics of both an acid and an aldehyde, granting it both acidic and reducing properties.
The strong acidity and reducing nature of formic acid make it highly valuable for a wide range of industrial applications, establishing it as an indispensable chemical in numerous industrial processes.
II. Production Methods of Formic Acid: From Traditional Processes to Modern Technology
The industrial production methods of formic acid have undergone multiple technological innovations. Currently, the following processes are primarily used:
1.Methyl Formate Method: This is currently the most mainstream method for producing formic acid. In this process, carbon monoxide first reacts with methanol to form methyl formate. The methyl formate is then hydrolyzed under acid catalysis to produce formic acid. This method is technologically advanced and economically viable, making it the dominant global process.
2.Sodium Formate Method: This is a more traditional method. Carbon monoxide reacts with sodium hydroxide under high temperature and pressure to produce sodium formate, which is then treated with sulfuric acid to yield formic acid. This method has relatively high material and energy consumption but is still used in some applications.
3.Formamide Method: Using sodium methoxide as a catalyst, carbon monoxide is passed through a methanol solution of ammonia to produce formamide. The formamide is then hydrolyzed with sulfuric acid to obtain formic acid.
Due to technological advancements, the Methyl Formate Method has become the preferred process due to its high efficiency and economic benefits, driving the rapid development of the formic acid industry.
