                                                         Application of thiourea in chemical industry

Thiourea has a wide range of applications in the chemical industry, mainly reflected in the following aspects:
As a chemical raw material
Synthetic drugs: It is an important intermediate for the synthesis of many drugs, such as sulfonamides,

anti-thyroid drugs, etc. Based on thiourea,

molecular structures with specific pharmacological activity can be constructed through a series of chemical reactions

to treat diseases such as bacterial infection and hyperthyroidism.
Synthetic dyes: Participate in the synthesis process of a variety of dyes,

provide specific structural units for dye molecules, thus giving dyes good dyeing performance and color stability,

widely used in textile, printing and dyeing industries.
Synthetic resin: thiourea formaldehyde resin can be prepared by reacting with formaldehyde and other substances.

This resin has good bonding properties, often used in the manufacture of plywood, fiberboard

and other wood processing products, can effectively improve the strength and durability of the board.
Synthetic rubber additives: It is the raw material of vulcanization accelerator

and antioxidant commonly used in the production of synthetic rubber. It can speed up the vulcanization rate of rubber,

improve the degree of cross-linking of rubber, thereby improving the physical and mechanical properties of rubber

and extending the service life of rubber products.
As a chemical intermediate
Metal surface treatment: thiourea can be used as an additive in the electroplating industry.

It can improve the performance of the electroplating solution,

improve the deposition rate of metal ions and the quality of the coating, make the coating more uniform,

dense and bright, and enhance the corrosion resistance and decoration of metal products.

In the metal cleaning and rust prevention treatment, thiourea can react with the oxide on the metal surface

to play the role of rust removal and rust prevention.
Chemical analysis reagents: In chemical analysis, thiourea is often used as a complexing agent,

masking agent and color developing agent. It can form stable complexes with many metal ions

and is used to separate and determine the content of metal ions. For example,

in the determination of metal ions such as copper, mercury, and silver,

thiourea can form complexes with these ions of a specific color,

which can be quantitatively analyzed by colorimetry or spectrophotometry.
Corrosion inhibitor: Because thiourea molecules contain nitrogen, sulfur and other atoms,

with a certain polarity and adsorption, can form a protective film on the surface of the metal

to prevent the corrosive medium from contact with the metal, thus playing a role in corrosion inhibition.

It is widely used in petrochemical, water treatment and other fields to prevent the corrosion of metal equipment

and pipelines in corrosive media.
Other fine chemical products: In the production of pesticides,

thiourea can be used to synthesize some pesticide varieties with insecticidal, bactericidal or herbicidal effects.

Thiourea is an important additive in photosensitive materials,

which can improve the sensitivity and stability of photosensitive materials.
