Compatibilization of asphaltenes in bituminous liquids using bulk phosphoamination

摘要

A method of compatibilization asphaltenes containing bituminous liquids which process comprises: a) reacting an asphaltene with phosphorous trichloride to form a phosphochlorinated asphaltene containing from about 0.01 wt % to about 20 wt % phosphorous; b) reacting the phosphochlorinated asphaltene with an equimolar amount of aliphatic or aromatic amines and polyamines selected from the group consisting of: (i) a piperzine; (ii) an aliphatic amine; (iii) an alkyl piperdize; (iv) an aligomeric mixed polyether aliphatic terminal diamine; (v) an oligomeric polyether aliphatic terminal amine; (vi) an oligermic polyether aliphatic terminal triamine; (vii) a substituted aromatic polyether terminal amine; and (viii) an oligomeric or polymeric amine to produce a capatibilized asphaltene; and (c) recovering the asphaltene product.
