Chloroform - Wikipedia

Industrially, chloroform is produced by heating a mixture of chlorine and either methyl chloride (CH3Cl) or methane (CH4). At 400–500 °C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + HCl CH2Cl2 + Cl2 → CHCl3 + HCl Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): WebSafety Data Sheet according to 29CFR1910/1200 and GHS Rev. 3 Effective date : 02.12.2015 Page 2 of 8 Chloroform, Reagent Grade Created by Global Safety … phileleftheros athlitika
