CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Benzyl chloroformate appears as a colorless liquid with an acrid odor. Vapors irritate eyes and mucous membranes. Corrosive to metals and tissue. Long-term inhalation of low concentrations or short-term inhalation of high concentrations can result in adverse health effects. |
|---|---|
| Color/Form | OILY LIQUID |
| Odor | ACRID ODOR |
| Boiling Point | 306 °F at 760 mmHg (decomposes) (USCG, 1999) |
| Melting Point | 0 °C |
| Flash Point | 227 °F Vigorous decomposition occurs at these temperatures; thus these values are anomalous due to the effect of the decomp. products (benzyl chloride and CO2). (USCG, 1999) |
| Solubility | SOL IN ETHER, ACETONE, BENZENE |
| Density | 1.22 at 68 °F (USCG, 1999) - Denser than water; will sink |
| Vapor Density | Relative vapor density (air = 1): 1 |
| Vapor Pressure | 7 mm Hg @ 85-87 °C |
| Decomposition | EMITS HIGHLY TOXIC PHOSGENE FUMES WHEN HEATED TO 100 °C. |
| Viscosity | 2.57 mPa-s (cP) @ 20 °C |
| Corrosivity | Corrosive |
| Heat of Combustion | -10.000 BTU/LB= -5,700 CALORIES/G= -240X10+5 JOULES/KG (ESTIMATED) |
| Heat of Vaporization | 90 BTU/LB= 50 CALORIES/G= 2.1X10+5 JOULES/KG (ESTIMATED) |
| Surface Tension | 25 DYNES/CM= 0.025 NEWTONS/M AT 20 °C (ESTIMATED) |
| Refractive Index | INDEX OF REFRACTION: 1.5175 @ 20 °C/D |
| Other Experimental Properties | DECOMP TO CO2 & BENZYL CHLORIDE UPON HEATING AT 100-155 °C |
| Chemical Classes | Toxic Gases & Vapors -> Acid Halides |
