Abstract Separation and purification of viscosity reducer for crude oil were performed with distillation and dissolution-precipitation. The functional group of its main component was identified by FTIR. It was deduced that the main component of the crude oil viscosity reducer is the tricopolymer of poly ethyl acrylate/methyl methacrylate/acrylic acid. The structure of the component was also ascertained and quantitively analysed with 1H NMR and MS. The mol ratio of the three monomers is 37.1∶25.8∶37.1, and the mass ratio is 41.1∶28.8∶29.8. The structure of the part soluble in methanol was identified by FTIR. The result showed that the nonionic sufactant is poly ethylene oxide with the moleculear mass range of 800-1 600, and the anionic surfactant is alkylbenzene sulfonate. The residue is accessory ingredient and water.
