CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Technical cyhexatin is a nearly odorless white crystalline powder that has no true melting point but degrades to bis(tricyclohexyl)tin oxide at 121 to 131 °C which decomposes at 228 °C; a melting point of 195-198 °C is also reported. Very insoluble in water (less than 1 mg/L at 25 °C), but wettable by water. Soluble in some organic solvents (acetone 1.3 g/L; xylenes 3.6 g/L; carbon tetrachloride 28 g/L; dichloromethane 34 g/L). Used as an acaricide (an agent to kill plant-feeding mites) in almonds, walnuts, hops and some fruits. |
