Abstract
Inventia se refera la un procedeu pentru prepararea bis-(4-trimetiltimidofenil)metanului utilizat la fabricarea de lacuri si materiale electroizolante, prin reactia între anhidrida trimelitica si 4,4-diaminodifenilmetan, la o temperatura cuprinsa între 130 si 190 degree C, în prezenta trietilfosfitului, drept catalizator. Reactia de imidizare are loc prin eliminarea azeotropica a apei cu ajutorul xilenului. Procedeul, conform inventiei, prezinta avantajul eliminarii în procesul de sinteza, a bis-(4-trimelitimidofenil)metanului, a solventilor polari cu temperatura de fierbere ridicata si toxicitate pronuntata.
