Malonic acid Uses
- Malonic acid is mainly used as a pharmaceutical intermediate in daily life, and is also used in spices, adhesives, resin additives, electroplating polishing agents, etc.
- Malonic acid and its esters can be used to synthesize barbiturates, vitamin B1, and vitamin B2. They are important pharmaceutical intermediates and are also intermediates for plant growth regulators such as indole esters. Therefore, they are often used in agriculture to synthesize plant growth regulators.
- In the chemical industry, malonic acid is a competitive aluminum surface treatment agent that decomposes by heating to produce acetic acid and water.
- The generated acetic acid can react with aluminum to produce aluminum acetate, hydrogen and water, which will not cause environmental pollution and has great advantages over acidic treatment agents such as formic acid.
- In the field of food processing, malonic acid and its esters are important food additives that can improve the flavor of the product.
