| titleOfInvention | A kind of aryl alkyl alcohol polyoxyethylene polyoxypropylene block copolymer and its preparation method and application |
| abstract | The invention discloses a kind of aryl alkyl alcohol polyoxyethylene polyoxypropylene block copolymer, there is logical structure shown in formula I, preparation method is alkene-carboxylic acid to be alkylated with aromatic hydrocarbon, obtain arylalkyl carboxylic acids, arylalkyl carboxylic acids and methyl alcohol carry out esterification and obtain arylalkyl carboxylic acids's methyl esters: can also be alkylated with aromatic hydrocarbon by alkene-carboxylic acid's methyl esters, obtain arylalkyl carboxylic acids's methyl esters, arylalkyl carboxylic acids's methyl ester hydrogenation is reduced into aryl alkyl alcohol, aryl alkyl alcohol and expoxy propane carry out ring-opening reaction, obtain aryl alkyl alcohol polyethenoxy ether, aryl alkyl alcohol polyethenoxy ether carries out ethoxylation with oxirane again, obtain aryl alkyl alcohol polyoxyethylene polyoxypropylene block copolymer.Aryl alkyl alcohol polyoxyethylene polyoxypropylene block copolymer, can be used for residual oil emulsification, the field such as prepared by reducing thick oil viscosity, heavy oil pour point depression, nanoemulsions, tertiary oil recovery, daily-use chemical industry. |
