carbon tetrabromide is an organic compound with the chemical formula cbr4. it can be prepared by reacting methane and bromine, the reaction formula is: ch4 + 4br2 —→ cbr4 +
4hbr. carbon tetrabromide can also be prepared by the reaction between carbon tetrachloride and bromide. carbon tetrabromide has two crystal forms, crystal form ii (or β) below 46.9°c and i (or β) above 46.9°c. or α). the single crystal has the c2/c space group and the unit cell parameter is a
= 20.9, b = 12.1, c = 21.2 (.10−1 nm), β = 110.5°. the bond energy of c-br is 235
kj.mol−1. its symmetry replaces the tetrahedral structure so that its dipole moment is 0 debye.
carbon tetrabromide can be used as a solvent for greases, waxes and oils, in the plastics and rubber industries for blow molding and vulcanization, for further use in polymerization, it can also be used as a tranquilizer and as a manufacturing agrichemical intermediates. as a component of refractory chemicals due to its non-flammability. due to its high density, it can also be used for the separation of minerals.
carbon tetrabromide is a highly toxic and irritating organic compound. it is not flammable but has a risk of explosion. after skin contact, contaminated clothing should be removed and the skin should be washed thoroughly with soap and water.
