Controlling hazardous chemicals in microreactors: Synthesis with iodine azide

Aromatic aldehydes have been converted into the corresponding carbamoyl azides using iodine azide. These reactions have been performed safely under continuous flow reaction conditions in microreactors.

Hazardous Chemicals in Carpets

This study was undertaken to investigate whether certain hazardous chemicals were present as components in new carpets, and if so, in what quantities. The study included analysis of eight new carpet samples that were available for retail in the UK. Some of the carpet samples contained high levels of organotins, in particular TBT (up to 47,500 ppb). One sample contained high levels (1600 ppb) of...

Hazardous Chemicals in PVC Flooring

This study investigated the composition of PVC flooring with respect to certain chemical additives, namely phthalate plasticisers and organotins. The study included analysis of five PVC flooring samples that were available for retail in the UK. Samples were found to contain high levels of several organotin compounds, in particular DBT (37.7 to 569 ppm) and TBT (128 to 17,940 ppb). Two phthalate...

Functionalized inorganic monolithic microreactors for high productivity in fine chemicals catalytic synthesis.

Highly productive: Grafted monolith silica skeleton microreactors process bulky molecules more efficiently than a batch mode reactor. This efficiency is due to a higher contact area, shorter diffusion path, and lower inhibition by products in the thin monolith skeleton. These materials provide a new approach in the field of heterogeneous catalysis for the synthesis of fine chemicals.
