64426-42-2 - Physico-chemical Properties
64426-42-2 - Introduction
thiourea is an organic compound with the chemical formula CS(NH2)2. It is a colorless crystalline solid, soluble in water and most organic solvents. This compound has the following properties:
1. Nature: Thiourea has a strong sour smell. It is very sensitive to heat and light and can decompose to form carbon disulfide and ammonia. Thiourea is a reducing agent that can be oxidized by oxidizing agents such as hydrogen peroxide and silver chloride. It can also form complexes, which can form stable complexes with metal ions.
2. Use: Thiourea has a wide range of applications. It is often used as metal silver extraction agent, catalyst and formaldehyde stabilizer. In addition, thiourea can also be used in the preparation of photosensitive materials, the synthesis of glyphosate (a herbicide) and rubber processing.
3. Preparation method: thiourea can be synthesized by ammonium carbonate and sulfur leaching method. First, ammonium carbonate and sulfur wire are put into a reactor and heated at an appropriate temperature to generate thiourea. The reaction process also produces byproducts such as NH4HS and carbon disulfide.
4. Safety Information: Thiourea has a certain toxicity and irritation, should not be in direct contact with the skin or inhalation of its dust. Take care to maintain proper ventilation and personal protective measures when using or storing thiourea. In addition, thiourea is potentially hazardous when exposed to strong oxidants and needs to be stored separately from other chemicals.
