متن کاملThe role of isocyanates in fire toxicity
Isocyanates are a group of low molecular weight, highly reactive compounds with a functional isocyanate group. The main human exposure route is via inhalation of airborne isocyanates, although dermal exposure has also been reported. The inhalation of isocyanates is associated with severely adverse health effects such as asthma, inflammation in the respiratory tract and cancer. During thermal de...
متن کاملA chronic eosinophilic pneumonia case with long exposure to isocyanates.
Chronic eosinophilic pneumonia (CEP) is a disease with unknown etiology, characterized by peripheral blood eosinophilia and abnormal eosinophil accumulation in the lungs. A 43-year-old male with 30 years history of exposure to isocyanates was admitted with the complaint of sputum, cough, progressive dyspnoea, and weight loss. Physical examination revealed bilaterally decreased breath sounds and...
متن کاملRh(III)-Catalyzed C-H Amidation of Indoles with Isocyanates.
The rhodium(III)-catalyzed direct amidation of indoles and pyrroles with aryl and alkyl isocyanates is described. These transformations provide a facile and efficient construction of C2-amidated N-heterocyclic scaffolds.
متن کاملAerosols of Isocyanates, Amines and Anhydrides
This thesis presents methods for air sampling and determination of isocyanates, amines, aminoisocyanates and anhydrides. These organic compounds are generated during production or thermal degradation of polymers such as polyurethane (PUR) or epoxy. Isocyanates, amines and anhydrides are airway irritants known to cause occupational asthma. Some of the isocyanates and diamines are listed as human...
