В вакуумном адиабатическом калориметре измерена теплоемкость в области 80-330 К и проведен дифференциальный термический анализ в области 80-550 К хлопковой микрокристаллической целлюлозы. Определены стандартные энтальпии сгорания и образования микрокристаллической целлюлозы и древесной целлюлозы с различным индексом кристалличности. В дифференциальном микрокалориметре при 303 К определена энтальпия ее взаимодействия с водой.In a vacuum adiabatic calorimeter the heat capacity of cotton microcrystalline cellulose was measured in the range 80 330 K and its differential thermal analysis was made between 80 and 550 K. Standard enthalpies of combustion and formation of microcrystalline cellulose and wood cellulose with a different index of crystallinity were determined. The enthalpy of its interaction with water was determined at 303 K in a differential microcalorimeter.
