Physical and chemical properties of Thiourea

Application of thiourea in chemical industry

Thiourea (Thiourea) has a wide range of applications in the chemical industry,

the following are its main application scenarios and specific uses:

1. Electroplating industry
Silver plating, gold plating: thiourea as an additive in the plating solution,

can improve the uniformity and gloss of the coating.

Corrosion inhibitor: In the process of metal pickling and rust removal,

thiourea is used as a corrosion inhibitor to reduce the corrosion of acid to the metal matrix.

2. Mineral processing industry
Flotation agent: Thiourea is used as a collector or inhibitor in the flotation of metal ores,

especially in the flotation process of copper, lead, zinc and other sulfide ores to improve metal recovery.

Precious metal extraction: In the extraction process of gold and silver,

thiourea can be used as a leaching agent to replace traditional cyanide and reduce environmental pollution.

3. Resin and plastics industry
Resin modification: thiourea is used to modify phenolic resin and urea-formaldehyde resin

to improve its heat resistance and mechanical properties.

Plastic additives: as stabilizers or antioxidants, extend the service life of plastic products.

4. Chemical synthesis
Intermediates: thiourea is an important intermediate for the synthesis of a variety of fine chemicals,

used in the production of medicine, pesticides, dyes and so on.

Vulcanizing agent: In the rubber industry, thiourea is used as a vulcanization accelerator

to enhance the elasticity and durability of rubber.

5. Environmental protection
Wastewater treatment: Thiourea is used to remove heavy metal ions (such as mercury,

cadmium, lead, etc.) from wastewater by forming stable complex precipitation.

Waste gas treatment: Thiourea can be used to remove sulfur dioxide (SO₂)

and nitrogen oxides (NOₓ) from industrial waste gas.

6. Battery industry
Electrolyte additive: In lead-acid batteries and lithium-ion batteries, thiourea is used as an additive

to the electrolyte to improve battery charging and discharging performance and cycle life.

Battery recycling: In the recycling process of used batteries, thiourea is used

to extract valuable metals (such as cobalt, nickel, etc.).

7. Textile industry
Dye additives: thiourea is used as a dye additive to improve dyeing effect and color fastness.

Flame retardants: In some textiles, thiourea can be used as a raw material for flame retardants.

8. The photography industry
Developer: Thiourea is used in the development process of black and white photos

to speed up the development reaction.

Application prospect of thiourea

1. Environmental protection
Wastewater treatment: Thiourea is excellent at removing heavy metal ions (such as mercury, cadmium, lead, etc.)

and may be more widely used in industrial wastewater treatment in the future.

Waste gas purification: thiourea can be used to remove sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) in industrial waste gas,

helping air pollution control.

Green chemistry: With the increasingly stringent environmental regulations,

thiourea, as an environmentally friendly reagent, may play a greater role in green chemical processes.

2. New energy
Battery technology: thiourea as an electrolyte additive can improve the charge

and discharge performance and cycle life of batteries,

and has broad application prospects in lithium-ion batteries, fuel cells and other fields in the future.

Hydrogen energy storage: thiourea and its derivatives show potential in the research of hydrogen energy storage materials

and may become an important part of the hydrogen energy economy.

3. Medicine and Biotechnology
Anticancer drugs: thiourea derivatives have shown good activity in anticancer drug research

and development, and may become a key component of new anticancer drugs in the future.

Protein research: The application of thiourea in the study of protein denaturation

and renaturation may drive further development in the field of biotechnology and life sciences.

4. Agriculture and food industry
Plant growth regulators: Thiourea's potential to improve crop stress resistance

and yield may make it a novel growth regulator in agriculture.

Food preservatives: thiourea, as an antioxidant and preservative,

may find more applications in the future in food preservation and extending shelf life.

5. New material development
Nanomaterials: thiourea, as a reducing agent or template agent,

plays an important role in the preparation of nanomaterials

and may promote the development of functional nanomaterials in the future.

Functional materials: thiourea can be used to synthesize materials with special optical,

electrical or magnetic properties for applications in electronics, energy and other fields.

6. Chemical and Manufacturing Industries
The application of thiourea in metal ore flotation

and precious metal extraction may further improve the efficiency of resource utilization.

Resin and plastic modification: The use of thiourea in resin and plastic modification may lead

to the development of high-performance materials.
