611-19-8 – Preparation Method

Open Data Verified Data

with o-toluidine as raw material, by diazotization replacement, chlorination derived. O-toluidine, hydrochloric acid and water were mixed and cooled to 0-5 °c, and sodium nitrite was added dropwise to conduct diazotization reaction. Under rapid stirring, pour cuprous chloride at 0 ℃, naturally raise the temperature to 20~25 ℃, and finally rise to 60~65 ℃, keep the temperature for 20min, then cool, stand, layer, wash and distill, O-chlorotoluene was obtained. O-chlorotoluene is mixed with phosphorus trichloride, and the chlorine is passed at 130~140 ℃ to obtain O-chlorobenzyl chloride.
