Frequently Asked Question About Thiourea
What is Thiourea?
Thiourea is an organosulfur compound that is composed of carbon, nitrogen, hydrogen, and sulfur atoms. It resembles urea but comprises sulfur instead of oxygen. It can be produced in the labs and is a valuable Mining Chemical.
What is Thiourea used for?
Being a highly valuable chemical compound, Thiourea serves a variety of purposes in the industry, including -
- It is used as a thiox precursor.
- It is utilised as a precursor to Thiourea Dioxide which is used as a reducing agent in textile processing.
- It is used as a fertilizer. For example, a seed pretreatment for priming or a foliar spray.
- Thioreau can act as a floatation reagent for metal minerals.
- It is utilized as an auxiliary agent in diazo paper, light-sensitive photocopy paper and most types of copy paper.
- It can also colour the photographic prints in silver-gelatin.
- It is used as a contaminant in the ethylene bisdithiocarbanate fungicides.
- It is used in industries for the production of flame retardant resins and vulcanisation accelerators.
- It can serve as an electroless tin plating solution for copper printed circuit boards.
What is the Chemical Formula of Thiourea?
Thiourea exists in two tautomeric forms – thione form and thiol form. The chemical formula is CH4N2S.
Is Thiourea harmful to life?
Once exposed to Thiourea, it can have adverse effects on your health due to its poisonous nature. It gets absorbed into the body either while inhaling its aerosol or by ingestion.
Recurring or extended exposure to this chemical compound can lead to skin sensitization and even affect your thyroid adversely.
Where is Thiourea found? What does Thiourea look like?
Thiourea is a chemically produced compound. It can be produced from ammonium thiocyanate but it is generally produced from the reaction of hydrogen sulfide with calcium cyanamide in the presence of carbon dioxide. The estimated global production of this compound is around 10,000 tonnes every year. Germany, China, and Japan are the major producers with 40%, 40%, and 20% production value respectively.
Thiourea appears as an odourless and lustrous powdery-white solid. It is soluble in water and has a bitter taste.
What are the Hazardous effects of Thiourea?
Thiourea can be extremely fatal with prolonged exposure without any precautions. One can develop skin allergy leading to itching and skin rashes due to extended exposure to this chemical. In extreme cases such as ingestion of this compound, it may damage the bone marrow causing reduced red blood cells, white blood cells and blood platelets.
What are precautionary measures necessary to be taken to handle Thiourea?
Thiourea should be handled as a carcinogen, i.e. with extreme caution. Some of the precautionary measures necessary in handling Thiourea are:
- The operation must be enclosed.
- Use of local exhaust ventilation at the site of chemical release.
- If neither of the above is followed, the use of respirators is a must.
- Wearing protective work clothing.
- Work clothes must be washed thoroughly immediately after the exposure to Thiourea and the end of the work shift.
- All the workers must be informed of all the health and safety hazards of the compound they deal with.
What will happen if Thiourea is heated?
Thiourea has a unique characteristic of changing to ammonium thiocyanate when heated above 130 °C.
Is Thiourea a soluble compound?
Thiourea is highly soluble in water (137 g/litre at 20 °C), polar protic and aprotic organic solvents.
Where can I buy Thiourea?
How much does Thiourea cost?
Thiourea has a low cost, keeping in mind its variety of use and effectiveness. The cost of this chemical depends on various production cost incurred during manufacturing. The estimated cost per tonne is $100.
What is the PH of Thiourea?
Thiourea has a pH of more than 3 making it a weak acid in nature.
Is Thiourea an Electrolyte compound?
Thiourea is an electrolyte compound. It is also used as an electrolytic additive in Lithium-Sulfur batteries.
Can Thiourea go down the drain?
Thiourea is an extremely hazardous chemical compound and cannot be disposed of down the drain. It is absolutely necessary to treat it as a hazardous waste. If there is a spill, one must immediately contact their fire department. Simply disposing it down the drain can lead to a catastrophic situation as it is extremely dangerous for the environment. Merely inhaling it can lead to an adverse effect on your health.
Is Thiourea Acidic or Basic?
Thiourea is weakly acidic in nature.
What is the difference between Thiourea and Urea?
Urea is an organic compound containing oxygen atoms, unlike Thiourea which is an organosulfur compound containing sulphur atoms. Thiourea is a much stronger acid than urea.
