21. Potassium reacts violently with halogens and detonates in the presence of bromine . 22. Shandong also produces bromine from underground wells and salt from sea water. 23. An incandescent light bulb is sufficient for bromine radical generation. 24. This compound reacted readily with air, chlorine, bromine and iodine. 25. This isotope decays by the emission of positrons and thus becoming bromine . 26. Bromoacetone is prepared by combining bromine and acetone, with catalytic acid. 27. Aldonic acids are typically prepared by oxidation of the sugar with bromine . 28. Displacement of bromine with the mercapto benzthiazole completes the synthesis of izonsteride. 29. It can be produced by oxybrominating butane with free oxygen and bromine . 30. It can turn chlorine pentafluoride and bromine pentafluoride into and, respectively:
