CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Collodion is a pale yellow syrupy liquid with an ether-like odor. Floats on water. Produces an irritating vapor. Immiscible with water. Boiling point is around 94 °F. (USCG, 1999) |
|---|---|
| Color/Form | Colorless, or slightly yellow, clear or slightly opalescent, syrupy liquid |
| Odor | Has odor of ether |
| Boiling Point | 93 °F at 760 mmHg (ether solvent) (USCG, 1999) |
| Flash Point | -49 °F (ether) (USCG, 1999) |
| Solubility | Immiscible with water |
| Density | 0.772 at 77 °F (USCG, 1999) - Less dense than water; will float |
| Stability/Shelf Life | PYROXYLIN: WHEN KEPT IN WELL-CLOSED CONTAINERS & EXPOSED TO LIGHT IT DECOMP |
| Autoignition Temperature | 356 °F (USCG, 1999) |
| Decomposition | The substance decomposes rapidly on burning causing fire and explosion hazard, producing nitrogen oxides. |
| Refractive Index | Cellulose nitrate films are optically anisotropic becuase of their microcrystalline structure. The colors change in polarized light in relation to the nitrogen content ... Index of refraction is 1.51 ... Exposure to sunlight, especially to ultraviolet light, has a detrimental effect on cellulose nitrate film by causing it to become yellowish and brittle. Solvents, softeners, and resins can either promote or hinder yellowing. /Cellulose nitrate/ |
| Other Experimental Properties | On addition of water the pyroxylin precipitates; exposed in thin layers, it evaporates leaving a tough, colorless film |
| Chemical Classes | Other Classes -> Other Organic Compounds |
