Benzal chloride is produced by the free radical chlorination of toluene, being preceded in the process by benzyl chloride (C 6 H 5 CH 2 Cl) and followed by benzotrichloride (C 6 H 5 CCl 3): C 6 H 5 CH 3 + Cl 2 → C 6 H 5 CH 2 Cl + HCl C 6 H 5 CH 2 Cl + Cl 2 → C 6 H 5 CHCl 2 + HCl C 6 H 5 CHCl 2 + Cl 2 → C 6 H 5 CCl 3 + HCl
A test strip is a band/piece/strip of paper or other material used for biological testing. Specifically, test strip may refer to: Food testing strips; Glucose meter test strip; Lipolysis test strip; Urine test strip; Universal indicator pH test strips; It may also refer to: Teststrip, an art gallery in Auckland, New Zealand
A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...
The French chemist Jean-Baptiste Dumas investigated the substitution of hydrogen for chlorine by acetic acid in candle wax as early as 1830. [1] He showed that for each mole of chlorine introduced into a hydrocarbon, one mole of hydrogen chloride is also formed and noted the light-sensitivity of this reaction. [ 2 ]
Benzyl chloride is prepared industrially by the gas-phase photochemical reaction of toluene with chlorine: [3]. C 6 H 5 CH 3 + Cl 2 → C 6 H 5 CH 2 Cl + HCl. In this way, approximately 100,000 tonnes are produced annually.
For example, benzyl chloroformate is used to introduce the Cbz (carboxybenzyl) protecting group and fluorenylmethyloxycarbonyl chloride is used to introduce the FMOC protecting group. Chloroformates are popular in the field of chromatography as derivatization agents.
