CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Formothion appears as viscous yellow oil or a crystalline mass. Used as an insecticide and acaricide on crops and ornamentals. Not presently produced commercially in the U.S. (EPA, 1998) |
|---|---|
| Color/Form | Yellowish liquid |
| Odor | Odorless |
| Boiling Point | Decomposes on distillation |
| Melting Point | 77 °F (EPA, 1998) |
| Solubility | Completely miscible with common organic solvents, e.g. alcohols, ethers, ketones, chloroform, benzene, toluene, xylene; slightly soluble in hexane; very slightly soluble in ligroin and paraffin oil. |
| Density | 1.361 at 68 °F (EPA, 1998) - Denser than water; will sink |
| Vapor Pressure | 8.5e-06 mmHg at 68 °F (EPA, 1998) |
| LogP | log Kow = 1.48 |
| Stability/Shelf Life | Hydrolyzed by water to dimethoate and (dimethoxyphosphinothioylthio)acetic acid; DT50 < or = 1 day @ pH 3-9 and 23 °C. Hydrolyzed more rapidly in alkaline media. Dilute solutions in non-polar organic solvents are stable. |
| Decomposition | When heated to decomposition it emits very toxic fumes of /nitrogen, phosphorous, and sulfur oxides/. |
| Corrosivity | Non-corrosive in general, tinplate is an exception |
| Refractive Index | INDEX OF REFRACTION: 1.5541 AT 20 °C/D |
| Kovats Retention Index | 1803.7 1839.9 1762 1810.5 1795 1805 1805.4 1810.3 |
| Other Experimental Properties | SOLIDIFIES AT ABOUT 25 °C |
| Chemical Classes | Pesticides -> Organophosphate Insecticides |
