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. Triphenylmethane is the basic skeleton of many synthetic dyes called triarylmethane dyes, many of them are pH indicators, and some display ...
After the German chemist August Kekulé and his Belgian student Antoine Paul Nicolas Franchimont (1844–1919) first synthesized triphenylmethane in 1872, [2] the Russian doctoral student Walerius Hemilian (1851–1914) first synthesized triphenylmethanol in 1874 by reacting triphenylmethyl bromide with water as well as by oxidizing triphenylmethane.
Melting point: 198 °C; 388 °F; 471 K Boiling point: 438 °C; 820 °F; 711 K Magnetic susceptibility (χ)-156.6·10 −6 cm 3 /mol
Melting point: 109 to 112 °C (228 to 234 °F; 382 to 385 K) Boiling point: 230 °C (446 °F; 503 K) ... Triphenylmethane; Triphenylmethyl hexafluorophosphate;
Oxidation with nitrous acid then produces the azo compound 4 from which on heating above the melting point, nitrogen gas evolves with formation of tetraphenylmethane 5. [ 2 ] Gomberg was able to distinguish this compound from triphenylmethane ( elemental analysis was not an option given the small differences in the hydrogen fractions of 6.29% ...
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.
The radical was discovered by Moses Gomberg in 1900 at the University of Michigan. [9] [10] [11] He tried to prepare hexaphenylethane from triphenylmethyl chloride and zinc in benzene in a Wurtz reaction and found that the product, based on its behaviour towards iodine and oxygen, was far more reactive than anticipated.
Triarylmethane dyes are synthetic organic compounds containing triphenylmethane backbones. As dyes , these compounds are intensely colored. They are produced industrially as dyes.
