Where is the new demulsification of new ionic liquids?
Harbin oriental patent office. The invention relates to an ionic liquid for demulsifying heavy crude oil and a demulsifying method thereof. Harbin Oriental Patent Office is located at Development Road, Daqing High-tech Development Zone, Heilongjiang Province. Among them, the ionic liquid used for demulsification of heavy crude oil is n? Alkyl trimethyl ammonium bromide or n? Alkyl trimethyl ammonium chloride; Said n? Preparation method of alkyl trimethyl ammonium bromide: 2 mol triethylamine and 25 mmol alkyl bromide are dissolved in 1mL toluene and mixed to prepare n? Alkyl ammonium bromide; Put 1 mol of 1? Methyl imidazole and 1 mol N? Alkyl ammonium bromide is mixed in a reaction tube, and then mixed with 1 mol of 1? Preparation of n by methyl pyridine reaction? Alkyl trimethyl ammonium bromide; Said n? Preparation method of alkyl trimethyl ammonium chloride: mix 1 mmol of trialkylamine and 2 mmol of chloromethane in a reaction tube filled with dichloromethane to prepare N? Alkyl trimethyl ammonium chloride. The invention has good demulsification effect, and solves the problem that the existing demulsification technology can not meet the exploitation and transportation of heavy crude oil fields.
