Abstract
The use of wood and wood-base interior finish materials in the construction of public and institutional buildings is often restricted because of the flammability of the pyrolytic products of wood. The wood product and treating industries have empirically developed chemical fire-retardants for wood that retard flammability and the spread of fire over lining surfaces. To improve these treatments systematically, additional information is needed on the action of the chemicals in changing the pyrolysis and combustion processes of wood and its components and the physical and chemical properties necessary for a chemical to be most effective in reducing flammability. In this study, a part of a series of investigations on pyrolysis and combusiton reactions of wood, dynamic thermogravimetric analyses were conducted under vacuum on pyrolysis of wood, of alpha-cellulose, and of lignin, untreated and treated with 2 percent by weight of five inorganic salts.
