Clariant has teamed up with Lavergne, a leader in the production of sustainable engineering resin from recycled plastic, to develop halogen-free flame-retardant polyester compounds made from ...

It was observed by C. W. Rice in 1944 that the emission of positive ions from a platinum anode heated in air is increased very markedly when vapours of compounds containing halogens such as carbon ...

IN the literature several indications of the existence of directed chemical bonds between organic halogen compounds and molecules containing atoms like nitrogen, oxygen or sulphur may be found.

THE FIRST DIRECT atmospheric measurements of iodine oxide and bromine oxide above the Antarctic snowpack unexpectedly indicate that the chemicals participate in destroying ozone and change the ...

In aliphatic or aromatic compounds, the replacement of hydrogen atom(s) by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene), respectively. In case of ...
