Application of Thiourea in chemical industry
1. Metal processing and surface treatment
Plating additive: thiourea is used as brightener in electroplating solution for silver,
gold and copper plating to improve the gloss and adhesion of the coating.
Metal polishing: thiourea can be used for chemical polishing of metal surfaces to improve surface finish.
Corrosion inhibitor for pickling: In the metal pickling process, thiourea acts as a corrosion inhibitor
to reduce the corrosion of acid to the metal matrix.
2. Precious metals extraction and recovery
Gold and silver leaching: thiourea solutions can be used to leech precious metals such as gold
and silver from ore or electronic waste as an environmentally friendly alternative to cyanide.
Metal separation: Thiourea forms complexes with specific metal ions for the separation
and purification of precious metals.
3. Chemical synthesis and catalysis
Pharmaceutical intermediates:
Thiourea is an important raw material for the synthesis of anti-thyroid drugs (such as methimazole)
and anticancer drugs.
Pesticide synthesis: For the preparation of insecticides, fungicides and herbicides.
Dye intermediates: thiourea is involved in the synthesis of certain dyes and pigments.
Catalyst: In some organic reactions, thiourea acts as a catalyst or cocatalyst to improve reaction efficiency.
4. Rubber and plastics industry
Vulcanization accelerator: thiourea accelerates the cross-linking reaction during rubber vulcanization,
improving the strength, elasticity and wear resistance of rubber products.
Plastic modification: thiourea can be used to improve the properties of certain plastics,
such as heat resistance and aging resistance.
5. Textile and printing industry
Dyeing aid: thiourea as a dyeing aid, improve the uniformity and color fastness of the dye.
Printing aid: In textile printing, thiourea helps the dye stick to the fiber better.
6. Environmental protection and water treatment
Heavy metal removal: thiourea forms complexes with heavy metal ions,
which are used to remove harmful metals such as lead, mercury and cadmium in industrial wastewater treatment.
Deoxidizer: thiourea is used in boiler water treatment to remove dissolved oxygen
and prevent corrosion of pipes and equipment.
7. Photography and imaging industry
Developer: Thiourea is used as a developer component to help reduce silver halide after exposure
to silver metal to form an image.
Stabilizer: Thiourea is used to stabilize the developer and extend its service life.
8. Laboratory and scientific research
Analytical reagents: Thiourea is used to detect and quantify certain metal ions (such as bismuth, lead, mercury, etc.).
Masking agent: In chemical analysis, thiourea is used to mask interfering ions to improve detection accuracy.
9. New energy and electronics industry
Battery materials: Thiourea is used to prepare some battery materials,
such as electrolyte additives for lithium-sulfur batteries.
Semiconductor processing: thiourea plays a role in the cleaning
and surface treatment of semiconductor materials.
10. Other special applications
Resin modification: thiourea is used to modify certain synthetic resins
to improve their heat resistance and mechanical properties.
Antioxidants: Thiourea has certain antioxidant properties and can be used
to protect certain chemicals or materials from oxidative degradation.
