  Physical and chemical properties of Thiourea

Molecular weight: 76.12 g/mol

Appearance: White or light yellow crystalline powder, glossy.

Odor: Odorless or slightly sulphide odor.

Density: 1.405 g/cm³ (20°C).

Melting point: 176-178°C (decomposition).

Chemical Safety:
Class 6.1 toxic substances

Solubility:
Water: soluble in water (about 13.7g /100 mL, 20°C);
Ethanol: slightly soluble in ethanol.

 

Acid base:
Thiourea is weakly basic and can react with acids to form salts.

Reducibility:
Thiourea has a certain reducibility and can be oxidized by oxidants (such as hydrogen peroxide, potassium permanganate).

Complexation:
Thiourea forms complexes with metal ions (e.g. Ag +, Au +, Cu² +) and is often used in metal extraction and electroplating industries.

Thermal stability:
When heated above the melting point, it decomposes, producing ammonia, hydrogen sulfide and other gases.

Hydrolysis reaction:
Hydrolysis under acidic or alkaline conditions to produce urea and hydrogen sulfide.

                                   Application of Thiourea in chemical industry

1. Electroplating industry
Brightener: thiourea is commonly used as an additive in electroplating solution,

especially in the process of silver, gold and copper plating, to improve the gloss and uniformity of the coating.

Stabilizer: Thiourea can stabilize metal ions in the plating solution and prevent their precipitation or decomposition.

2. Metal extraction and separation
Coordination agent:

Thiourea can form stable complexes with a variety of metal ions (such as gold, silver, platinum, mercury, etc.),

so it has important applications in the extraction and separation of precious metals.

Leaching agent: thiourea solution can be used to leach gold, silver and other precious metals from ores.

3. Corrosion inhibitors
Metal protection: Thiourea can be added as a corrosion inhibitor to pickling solution or cooling water

to protect metal surfaces from corrosion.

Acidic environment: In acidic media, thiourea can effectively inhibit the corrosion reaction of metals.

4. Chemical synthesis
Intermediates: thiourea is an important intermediate for the synthesis of many organic compounds,

such as medicine, pesticides, dyes and so on.

Catalyst: Thiourea is used as a catalyst or cocatalyst in some organic reactions.

Reducing agent: thiourea has certain reducing properties and can be used

to reduce certain metal ions or organic compounds.

5. Rubber industry
Vulcanization accelerator: thiourea is used as an accelerator in the rubber vulcanization process,

which can accelerate the vulcanization reaction and improve the performance of rubber products.

6. Textile industry
Dyeing aid: thiourea can be used as a dye aid to improve the uniformity and color fastness of dyeing.

Printing aid: In the textile printing process, thiourea can improve the printing effect.

7. Water treatment
Deoxidizer: Thiourea can be used to remove dissolved oxygen from water

and prevent corrosion of boiler and piping systems.

Heavy metal removal:

thiourea can form complexes with heavy metal ions for the removal of heavy metals in wastewater treatment.

8. Analytical chemistry
Reagent: Thiourea is often used in analytical chemistry as a reagent for the detection of metal ions

(such as bismuth, lead, mercury, etc.).

Masking agent: Thiourea can mask certain metal ions to avoid interfering with the analysis results.

9. The photographic industry
Developer: Thiourea can be used as a photographic developer to help reduce silver ions in the developer to metallic silver.

10. The pharmaceutical industry
Drug synthesis: thiourea is an important raw material for the synthesis of some drugs

(such as anti-thyroid drugs, anti-cancer drugs).

Antioxidants: Thiourea has certain antioxidant properties and can be used in pharmaceutical preparations.

11. Other applications
Pesticide synthesis: Thiourea is used in the synthesis of certain insecticides and herbicides.

Resin modification: thiourea can be used to modify certain resins to improve their properties.
