Allgemeine Beschreibung

p-Tolyl isocyanate reacts with human serum albumin to form antigen which helps in detecting IgE antibodies in workers hypersensitive to toluene diisocyanate.

Anwendung

p-Tolyl isocyanate was used to study the catalytic role of supported Rhodium(I) complex toward the reductive carbonylation of nitrobenzene in DMF medium.

Toluene diisocyanate (TDI) sensitivity accompanied by nonspecific bronchial hyperresponsiveness occurs in approximately 5% of occupationally exposed workers. We report the case of a 32-yr-old worker followed longitudinally after removal from isocyanate exposure. TDI reactivity was lost 11 mo after removal

A series of new flame retardants (FR) based on dibenzo[d,f][1,3,2]dioxaphosphepine 6-oxide (BPPO) incorporating acrylates and benzoquinone were developed previously. In this study, we examine the fire behavior of the new flame retardants in polyisocyanurate (PIR) foams. The foam characteristics, thermal
