СИНТЕЗ И ХАРАКТЕРИСТИКА АЦЕТОНИТРИЛА: ТЕПЛОВЫЕ ЭФФЕКТЫ СГОРАНИЯ

Abstract

Acetonitrile (CH-CN) is an important organic compound widely used in chemical synthesis, analytical chemistry and industry. Determination of its enthalpy of combustion is a key parameter for energy calculations and optimization of technological processes. In this work, the enthalpy of combustion of acetonitrile was experimentally determined using an IKA C 6000 calorimeter in isoperibol mode. Accurately weighed acetonitrile samples were placed in polyethylene ampoules, after which combustion was carried out in an oxygen environment with recording of the temperature rise. The obtained temperature data were used to calculate the amount of heat released and, accordingly, the enthalpy of combustion.
