  • A new method to simultaneously separate neutral nitrogen compounds and alkylphenols from crude oil was introduced in this paper.The crude oil in which asphaltane has been removed is put into a non polar C18 column,and the column is eluted by 15mL of hexane and 15mL of dichloromethane in turn.Most saturated hydrocarbon and aromatic hydrocarbon are eluted out after 5mL of hexane has been used.The neutral nitrogen compounds are separated after 6mL of hexane is added and the alkylphenols are obtained as soon as dichloromethane is added.The experiment results showed that the repeatability and stability of the method were satisfied.There are some advantages such as fewer regents,shorter proces sing time and purer neutral nitrogen compounds,compared with other methods.
