CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Chlorendic acid appears as fine white free-flowing crystals or white powder. Odorless. (NTP, 1992) |
|---|---|
| Color/Form | Crystalline solid |
| Melting Point | 406 to 410 °F (NTP, 1992) |
| Solubility | less than 1 mg/mL at 70 °F (NTP, 1992) |
| Density | 0.95 (NTP, 1992) - Less dense than water; will float |
| Vapor Pressure | 0.00000003 [mmHg] |
| LogP | log Kow= 2.30 |
| Henry's Law Constant | Henry's Law constant=3.0X10-14 atm-cu m/mole @ 25 °C /Estimated/ |
| Stability/Shelf Life | The acid loses water in a heated open system, tends to discolor and forms the anhydride, which melts at 230-235 °C. ...Chlorendic acid is very resistant to hydrolytic dechlorination... . |
| Decomposition | When heated to decomposition it emits toxic fumes of /hydrogen chloride/. |
| Dissociation Constants | pKa=3.1 |
| Other Experimental Properties | Loses water in a heated open system to give the anhydride; emits chlorine when heated to decomposition. |
| Chemical Classes | Other Classes -> Organic Acids |
