Organochlorine compounds and their reactions in the atmosphere
Ecotoxicology and Environmental Safety, 1978 Abstract To estimate the influence of the chlorinated hydrocarbons on the quality of the environment, primarily chemico-ecological and toxico-ecological data are required. In addition to their level of production, range of application, and distribution tendency, a knowledge of their transformation under environmental conditions is desirable.

Chlorinated Byproducts in Diisocyanates Synthesis From 35Cl Nuclear Quadrupole Resonance
Helvetica Chimica Acta, EarlyView.We combine 35Cl NQR spectroscopy & DFT to identify trace chlorinated impurities in industrial MDI streams, creating a non‐destructive “analytical ruler” for chemical process monitoring. ABSTRACT Chlorinated impurities in industrial diisocyanates production significantly impact product quality and stability, yet their speciation remains an analytical ...
