FIELD: chemistry.
SUBSTANCE: invention relates to acetylation of peat derivatives and can be used in production of plastic mass. The peat esterification method involves mechanical treatment of peat with sodium hydroxide while grinding in a planetary mill AGO-3, followed by esterification with acetic anhydride at 80-100°C for 2-8 hours.
EFFECT: broadening the raw material base using peat in chemical processing by acetylation, cutting consumption of reactants and duration of the process.
