Aspects of the environmental chemistry of methoxychlor
Preliminary investigations on the Environmental Chemistry of Methoxychlor [2,2-bis (p - methoxyphenyl)-1,1,1- trichloroethane], a potential DDT replacement, have been conducted with emphasis on its degradation by ...
Molecular and intramolecular relaxation processes of small molecules
The dielectric relaxation method was used to determine the activation parameters of some ethane derivatives and simple amides. A General Radio 1615-A capacitance bridge was utilized to obtain the energy barriers of the ...
Thermal decomposition and gasification of cellulose and wood wastes
The thermal decomposition of jack pine bark, white birch sawdust and cellulose has been studied by both isothermal weight-change determinations and dynamic thermogravimetry mostly in inert atmospheres up to 900°C. Gaseous ...
