FIELD: electricity.
SUBSTANCE: invention relates to measurement of electric conductivity of liquid media and can be used in chemical and paint industry. Method includes heating a working mixture to temperature of 240-245 °C, wherein monitoring of reaction is carried out by continuous measurement of current values of electrical conductivity of reaction mixture in process of heating by passing through reaction mixture an electric current using built into process pipeline electrodes, wherein maximum conductivity of mixture, not varying during holding, means end of re-esterification reaction.
EFFECT: higher safety of process and electrical power saving.
