Thermal stability and thermal degradation reaction kinetics of 4,4'-diphenylmethane diisocyanatetrimer
The trimer of 4,4'-diphenylmethane diisocyanate (MDI) is synthesized using 2,4,6-tris(dimethylaminomethyl) phenol (DMP-30) as catalyst. The thermal stability of MDI and its trimer and thermal degradation reaction kinetics for MDI trimer are studied by the
Aluminium-catalysed isocyanate trimerization, enhanced by exploiting a dynamic coordination sphere
Main-group metals are inherently labile, hindering their use in catalysis. We exploit this lability in the synthesis of isocyanurates. For the first time we report a highly active catalyst that trimerizes alkyl, allyl and aryl isocyanates, and di-isocyanates, with low catalyst loadings under mild conditions, using a hemi-labile aluminium-pyridyl-bis(iminophenolate) complex.
