CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Prothoate is a colorless crystalline solid, with a camphor-like odor. Technical product is an amber to yellow semi-solid. Used as an insecticide and an acaricide. (EPA, 1998) |
|---|---|
| Color/Form | Colorless yellow crystals (tech is an amber to yellow semi-solid) |
| Odor | Camphor-like odor |
| Melting Point | 83.3 °F Technical product solidifies at 70-75 °F. (EPA, 1998) |
| Solubility | SOLIDIFIES AT 21 TO 24 °C; AMBER TO YELLOW SEMI-SOLID; MISCIBLE AT 20 °C WITH MOST ORGANIC SOLVENTS; SOLUBILITY LESS THAN: 10 G/KG GLYCEROL, 20 G/KG LIGHT PETROLEUM, 30 G/KG CYCLOHEXANE, HEXANE & HIGHER PETROLEUM FRACTIONS /TECHNICAL PRODUCT/ |
| Density | 1.151 at 89.6 °F (EPA, 1998) - Denser than water; will sink |
| Vapor Pressure | 0.0001 mmHg at 104 °F (EPA, 1998) |
| Stability/Shelf Life | It is stable in neutral, moderately acid or slightly alkaline media but, at pH 9.2 & 50 °C it is decomposed in about 48 hr |
| Decomposition | When heated to decomposition it emits very toxic /nitrogen, phosphorous, and sulfur oxides/. |
