Triphenylmethane - LoveToKnow 1911 (476 words) |
 | TRIPHENYLMETHANE, (C 6 H 5) 3 CH, a hydrocarbon, important as being the parent substance of several series of exceedingly valuable dyestuffs, e.g. |
| Triphenylmethane is a white crystalline solid, melting at 9 2° and boiling at 358°. |
| 3150, et seq.) by acting on triphenylmethane chloride (from triphenylmethane carbinol and phosphorus pentachloride, or from carbon tetrachloride and benzene in the presence of aluminium chloride) and its homologues with zinc, silver or mercury. |
| Kinetics: Fading of Triphenylmethane Dyes (919 words) |
| Triphenylmethane dyes are water-soluble organic compounds that contain a colored cation. |
| The reaction of OH ion with triphenylmethane dyes results in a disruption of the conjugation and loss of color. |
| Since the absorbance of the violet colored triphenylmethane cation is directly proportional to its concentration, the kinetics of the reaction can be determined by measuring the change in absorbance as a function of time. |
