POLYURETHANE-BASED HYDRATE FORMATION AND CORROSION INHIBITOR FOR THE EXTRACTION, PROCESSING AND TRANSPORTATION OF HYDROCARBON RAW MATERIALS Russian patent published in 2021 - IPC C09K8/52 C09K8/54 C23F11/14 

Abstract RU 2746210 C1

FIELD: chemistry.

SUBSTANCE: invention relates to the chemistry of polymer compounds, namely, to an inhibitor of hydrate formation and corrosion based on polyurethanes for the extraction, processing and transportation of hydrocarbon raw materials of general formula I, including isomers:

where the sum of n, m, x and z is a number sufficient to obtain a molecular weight of 1850-2000 Da at R = ethyl CH3-CH2–(I-1) (Et), R = n-propyl CH3–CH2–CH2–(I-2) (n-Pr), R = n-butyl CH3−CH2−CH2−CH2−(I-3) (n-Bu).

EFFECT: increased efficiency of preventing the formation of gas hydrates and corrosion.
