Abstract A necessary and sufficient condition for stability of the empty adiabatic tubular reactor with axial mixing is derived which depends upon steady state information alone. The stability conditions require the solution of a linear ordinary differential equation and the character of this solution determines the stability or instability of the system without the use of transient calculation. The lumped constant reactor is always stable. The method of computation requires a minimum amount of memory capacity in a digital computer and could be carried out on an analogue computer with ease.
