Dimethylolbutyric acid (DHMBA) is an important organic chemical raw material, widely used in medicine, pesticides, plastics, coatings and other fields. This article will detail the nature and use of DHMBA.

1. Dimethylol Butyric Acid Properties

1. Physical Properties
DHMBA is a white crystalline powder with a high melting point, generally between 130-132 ℃, soluble in organic solvents such as water and ethanol, and slightly soluble in ether and benzene. DHMBA has high moisture absorption, so it is necessary to pay attention to moisture during storage and use.

2. chemical properties
DHMBA molecule contains two hydroxymethyl functional groups, with strong reactivity, can be with a variety of compounds esterification, etherification, condensation and other reactions. In addition, DHMBA is acidic and can react with bases to form salts.

2. the use of dimethylol butyric acid

1.
in the field of medicine DHMBA has a wide range of applications in the field of medicine, can be used as intermediates in the synthesis of drugs, for the preparation of antibacterial drugs, anti-tumor drugs, anti-tuberculosis drugs and other drugs. For example, DHMBA can react with phenylalanine to produce the anticancer drug, nitrogen mustard, and also with amino acids to produce antibacterial drugs.

2. Pesticide field
DHMBA also has a wide range of applications in the field of pesticides, can be used as pesticides, fungicides, herbicides and other pesticides synthetic intermediates. For example, DHMBA can react with phenol to produce the pesticide fungicide dimethylolphenol, and can also react with acetone to produce the pesticide herbicide pyruvic acid.

3. Plastic field
DHMBA can be used as a plastic additive to improve the toughness and strength of plastics. At the same time, DHMBA can also react with other compounds in the plastic to form a cross-linked structure to improve the heat resistance and chemical resistance of the plastic.

4.
in the field of coatings DHMBA can be used as a coating additive to improve the adhesion and water resistance of coatings. At the same time, DHMBA can also react with other compounds in the coating to generate coatings with special functions, such as waterproof coatings, anti-corrosion coatings, etc.

In conclusion, as an important organic chemical raw material, dimethylol butyric acid has a wide range of applications in the fields of medicine, pesticides, plastics, coatings and so on. Understanding the nature and use of DHMBA is of great significance for rational use of resources, improving product quality and reducing costs.
