Triphenylmethanol (also known as triphenylcarbinol and TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene. In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable "trityl" carbocation ...
It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
Triphenylmethane or triphenyl methane (sometimes also known as Tritan), is the hydrocarbon with the formula (C 6 H 5) 3 CH. This colorless solid is soluble in nonpolar organic solvents and not in water.
Column J is the color scheme used by the molecular visualizer Jmol. [9] Column R is the scheme used by Rasmol; when two colors are shown, the second one is valid for versions 2.7.3 and later. [9] [10] Column P consists of the colors in the PubChem database managed by the United States National Institute of Health.
Triphenylcarbenium Space-filling model of the Ph 3 C + ion. In chemistry, triphenylcarbenium, [1] triphenylmethyl cation, tritylium , [2] or trityl cation is an ion with formula [C 19 H 15] + or (C 6 H 5) 3 C +, consisting of a carbon atom with a positive charge connected to three phenyl groups.
Solutions containing the radical are yellow; when the temperature of the solution is raised, the yellow color becomes more intense as the equilibrium is shifted in favor of the radical rather than the colorless dimer, in accordance with Le Chatelier's principle. The triphenylmethyl radical exhibits green photoluminescence. Further reaction of ...
[citation needed] Some triphenylmethanol is also formed under very acidic conditions when the positive charges on the nitrogen atoms lead to an enhancement of the electrophilic character of the central carbon, which allows the nucleophilic attack by water molecules. This effect produces a slight fading of the yellow colour.
Triphenylmethyl chloride is commercially available. It may be prepared by the reaction of triphenylmethanol with acetyl chloride, or by the Friedel–Crafts alkylation of benzene with carbon tetrachloride to give the trityl chloride-aluminium chloride adduct, which is then hydrolyzed. [3]
