Deodorization by Combustion of Triethylamine and of Dimethyl Sulfide

Abstract

The rate of combustion reaction either of triethylamine or of dimethyl sulfide was investigated. The reactor was a quartz pipe packed with a bundle of quartz capillary and a reactant gas was prepared by inserting a small amount of liquid triethylamine (or dimethyl sulfide)into a N₂-O₂ mixed gas.
The efficiencies of comiustion of each substance were observed under various conditions: ( 1 ) the initial concentration of triethylamine (or dimethyl sulfide) (700, 2700p pm); ( 2 ) the content of oxygen gas (21-100 mole percent); ( 3 ) temperature (500-610°C). Based on the temperature distribution within the reactor, which was well expressed by a cubic equation with respect to the distance, experimental results were analyzed by the nonlinear least squares method. The following overall rate equations were finally obtained: r=kc'C^0.2_O2C^1.3_A for triethylamine from Fig.8 and Table 2, and r-=kc'C^m_O2C^1.1_A for dimethyl sulfide from Table 3.
