Kinetics of the gas-phase pyrolysis of 1-t-butylbut-3-enyl acetate

The pyrolysis of 1-t-butylbut-3-enyl acetate has been studied in a static system in the temperature range 300–350°C and pressure range 35–300 mmHg. The reaction is homogeneous and of the first order. The rate of the reaction is given by the equation log (k1/s–1)= 14·14 ± 0·01 –(46,400 ± 600) cal mol–1/2·303 RT. The effect of a β-unsaturated substituent in the elimination of secondary acetates is discussed.
