Description

General description

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

Application

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

A study of serum antibody activity in workers with occupational exposure to diphenylmethane diisocyanate.

K S Tse et al.

Allergy, 40(5), 314-320 (1985-07-01)

The prevalence of sensitization was studied in a group of 76 foundry workers with occupational exposure to diphenylmethane diisocyanate (MDI). Ten workers had clinical evidence of asthma, 40 had non-asthmatic respiratory symptoms, and 26 were asymptomatic. Specific IgE antibodies to

Improving the Flame Retardance of Polyisocyanurate Foams by Dibenzo[d,f][1,3,2]dioxaphosphepine 6-Oxide-Containing Additives.

Johannes Lenz et al.

Polymers, 11(8) (2019-07-31)

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
