Phenol from Toluene, Coproduct Formaldehyde
Published: February 1981
A process for making phenol from toluene with coproduction of paraformaldehyde based on Suntech patents is studied. On the basis of estimated raw material usages and an analogy with a similar process starting from ethylbenzene, we conclude that this process will not be economic unless the selectivity of the process can be improved dramatically.
