TURBULENT VISCOSITY REDUCING ADDITIVE WITH ANTICORROSION PROPERTIES Russian patent published in 2017 - IPC F17D1/16 F15D1/02 C08F10/00 C08F10/14 C08L23/18 C08K5/05 

FIELD: chemistry.

SUBSTANCE: turbulent viscosity reducing additive with anticorrosion properties contains the ultrahigh-molecular polymer of alpha-olefins, the condensation product of higher amines with carbon atoms number of 6-30 with the oxyalkylation degree of 2-50, while using as the oxyalkylating agent of the epoxy compound with the carbon atoms number of 2-6 with the dibasic organic acid and the carbon atoms number 3-9, the solvent. The mixture of linear and branched aliphatic monoatomic and polyatomic alcohols and/or ethers with the carbon atoms number of 1-15 is used as the solvent.

EFFECT: reduction of the hydraulic resistance in the main pipeline and increase of its throughput capacity with simultaneous protection against the corrosion of the main pipeline inner surface and the equipment associated with it, used for transportation of hydrocarbon liquids.
