Application of Microstructured Reactor Technology for the Photochemical Chlorination of Alkylaromatics

CHIMIA, 2002
The advantageous application of a falling-film microreactor for a photochemical gas/liquid reaction was demonstrated by the selective photochlorination of toluene-2,4-diisocyanate (TDI). In the microstructured reactor the selectivity to the side-

Silicas with Polyoxyethylene Branches for Modification of Membranes Based on Microporous Block Copolymers

Membranes, 2023
We have synthesized cubic and linear polysiloxanes containing polyoxyethylene branches (ASiP-Cu) using tetraethoxysilane, polyoxyethylene glycol, and copper chloride as precursors; the products are stable to self-condensation.

Expression kinetics of miRNA involved in dermal toluene 2,4-diisocyanate sensitization

Journal of Immunotoxicology, 2013
Allergic disease is an important occupational health concern, with work-related asthma and allergic contact dermatitis being the most frequently diagnosed occupational illnesses. Diisocyanates, particularly toluene 2,4-diisocyanate (TDI), have been the leading cause of occupational asthma for many years.
