Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
A solution of 1-bromopropane in ether - typically diethyl ether or tetrahydrofuran - is treated with magnesium, which inserts itself into the organohalogen bond. As both the magnesium metal and the product are sensitive to water, the reaction must take place in anhydrous conditions. [3] C 3 H 6 −Br + Mg → C 3 H 6 −Mg−Br
It is somewhat soluble in water and readily evaporates into the air. Bromoform is the main trihalomethane produced in beachfront salt water swimming pools with concentrations as high as 1.2 ppm (parts per million). Concentrations in freshwater pools are 1000 times lower. [9] Occupational skin exposure limits are set at 0.5 ppm. [10]
