Physicochemical property
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. |
