Determination of organic chlorine content in crude oil

The pre-naphtha fraction is obtained by crude oil distillation, and the distillation method should be carried out
according to the requirements of GB/T6536.
Naphtha fractions are sufficiently eluted with alkali and water to remove hydrogen sulfide and inorganic chlorides
.

The organochlorine content
in the calculated naphtha fraction was determined by the following two methods.

Method: The eluted naphtha fraction was transferred to a dispensing funnel containing sodium biphenyl dissolved in
toluene.
Sodium biphenyl can convert organic halides into inorganic halides, evaporate and concentrate the aqueous phase, and add human acetone for potentiometric titration, thereby calculating the organochlorine content
in crude oil.
Organic bromide and organic iodide in crude oil have an impact
on this method.
