| titleOfInvention | The preparation method of chitosan class natural macromolecule modification crude oil desalting demulsifier |
| abstract | The present invention relates to a kind of preparation methods of chitosan class natural macromolecule modification crude oil desalting demulsifier.Specific step is as follows: 1) poly glycol monomethyl ether being carried out halogenation modification；2) glycidyl dimethyl alkyl ammomium chloride is prepared；3) quaternized carboxyalkyl chitosan is prepared；4) it by modified poly (ethylene glycol) monomethyl ether and quaternized carboxyalkyl chitosan reaction, obtains target product poly glycol monomethyl ether and is grafted quaternized carboxyalkyl chitosan.The present invention has many advantages, such as from a wealth of sources, natural, nontoxic, sustainable, product bio-compatibility is good, degradable using chitosan class natural polymer as raw material.Not only breaking emulsion and dewatering effect is good for demulsifier produced by the present invention, simultaneously because containing a large amount of carboxyalkyl group and quaternary ammonium salt group on demulsification agent molecule, there is very strong binding ability in electronegative particle to the electronegative ions such as metal cation, cycloalkanes acid group and surface, therefore has both the ability of removing oil-soluble salt while demulsification. |
