Research of thermal destruction of aliphatic alcohols in pure state and dissolved in water
By the method of isothermal pressure increasing in a closed system starting temperatures (TS) of thermal decomposition of aliphatic alcohols (methanol, ethanol, 1-propanol and 1-butanol) in their water solutions depending on composition are obtained. Values of TS depending on composition (x) and num...

description | By the method of isothermal pressure increasing in a closed system starting temperatures (TS) of thermal decomposition of aliphatic alcohols (methanol, ethanol, 1-propanol and 1-butanol) in their water solutions depending on composition are obtained. Values of TS depending on composition (x) and number of carbon atom (C) are described by the polynomial equation: 544.258 2 28.826 10 3 2 65.617 6.378 10 2 ( , ) 23.622 + − + ⋅ − T x N = x − x + ⋅ N N . It is shown that the rate of alcohol decomposition depends on temperature and concentration (in water-alcohol solution). To estimate rate of thermal decomposition of alcohols we used change of pressure of system in a unit of time at constant temperature and volume (closed system). Reaction rate constant was calculated by formula: dτ dp p k = 1 ⋅ , where k – reaction rate constant; p – pressure; τ – time; dp/dτ – rate of reaction. Values of kinetic and activation parameters of alcohol decomposition in the range of temperatures 583.15–663.15 К are estimated. |
