Popis:	An investigation has been made of the decomposition of solid and molten azoisobutyronitrile (AIBN). Below the melting point, the decomposition is first very slow; then a brief period of autocatalysis is followed by a gradual reduction in rate; when melting occurs, acceleration occurs again as the proportion of molten material increases. It appears that there is a crystal-form of AIBN favourable for decomposition; the rate for this form is considerably greater than for AIBN in solution. It is proposed that there is an energy-chain decomposition in which there is transfer of energy from excited tetramethylsuccinodinitrile to a neighbouring molecule of AIBN.
