A process for preparing organic chlorides in which the chlorine atom is bonded to a CH
2
group by reacting the corresponding alcohols with thionyl chloride in the presence of a triaylphosphine oxide at a temperature of from 20 to 200° C. and a pressure of from 0.01 to 10 MPa abs, which comprises using the triarylphosphine oxide in a molar ratio to the amount of OH groups to be chlorinated of from 0.0001 to 0.5.
一种制备有机
氯化物的方法,其中
氯原子与一个
CH2基团结合,通过在20至200°C温度和0.01至10兆帕绝对压力下,在三芳基膦氧化物存在下,将相应的醇与亚砜
