Popis: 1. Depending on the cyclotrimerization conditions, phenylcyanamide forms two isomeric forms of triphenylmelamine. 2. At temperatures above its melting point, triphenylisomelamine is isomerized to the normal structure, namely 2,4,6-triphenylamino-1,3,5-triazine. 3. In solution the isomerization of triphenylisomelamine to the normal triphenylmelamine proceeds under milder conditions than when the reaction is run in bulk.
