1,2-Dibromopropane Usage And Synthesis
Chemical Properties1,2-Dibromopropane is considered non-flammable and non-explosive liquid.
Uses1,2-Dibromopropane is used in organic synthesis and solvent. It was used to study the effect of reductant concentration, reductant contact time and suspension pH on reductive dechlorination of carbon tetrachloride by soil manipulated with Fe(II) and HS-. It was used as internal standard during the determination of nitrogenous disinfection byproduct trichloronitromethane by gas chromatography mass spectrometry.
ApplicationPhotodissociation dynamics of 1,2-dibromopropane at 234 and 265 nm has been investigated by using velocity map ion imaging method. 1,2-Dibromopropane was used to study the effect of reductant concentration, reductant contact time and suspension pH on reductive dechlorination of carbon tetrachloride by soil manipulated with Fe(II) andHS-. It was used as internal standard during the determination of nitrogenous disinfection byproduct trichloronitromethane by gas chromatography mass spectrometry.
Preparation1,2-Dibromopropane is synthesized from bromopropane by bromination.
First mix bromopropane and iron powder, heat to 40-50°C, slowly add bromine, and continue to reflux for 2h after adding. Then, the iron slag was filtered off, and the filtrate was washed several times with water, once with 5% sodium carbonate solution, and then with 5% sodium thiosulfate solution to remove free bromine. Dry with anhydrous calcium chloride. Fractional distillation, collecting 139-142 ℃ fraction is the finished product of 1,2-dibromopropane.
