FIELD: chemistry.
SUBSTANCE: invention relates to the chemistry of polymer compounds that inhibit the growth of methane hydrates, and can be used in the oil and gas industry in the processes of production, preparation and transportation of hydrocarbons to prevent the growth of gas hydrates. The base growth inhibitor of methane hydrates is sulfonated chitosan of the formula (I):
.
EFFECT: obtaining an effective biodegradable and safe oil-field growth inhibitor of gas hydrates, expanding the range of oil-field reagents for this purpose, while reducing economic costs and minimizing the impact on the environment.
