Abstract
Production of barium oxide compositions is effected by heating together particulate barium oxide and 0,1 to 10% of barium carbonate, at a temperature of at least 950 DEG C. (preferably 1000 DEG to 1200 DEG C.) whilst mixing the particles of barium oxide, for at least 5 minutes. The mixing may be effected by using a rotary kiln, a fluidized bed, or an extended bed. If a fluidized or extended bed is used the fluidizing agent is an inert gas, e.g. nitrogen. The resulting barium oxide compositions may be employed to produce barium detergents (see Group IV(b)). Specifications 759,765, 759,766, 759,821, 836,797 and 845,122 are referred to.ALSO:Barium oxide is treated with methanol to produce a barium methylate solution which is then reacted with a sulphonic acid e.g. benzene sulphonic acid to produce a barium detergent. In an example barium oxide is treated with methanol at 30 DEG to 40 DEG C., and the solution is filtered at 30 DEG to 40 DEG C. Specifications 759,765, 759,766, 759,821, 836,797 and 845,122 are referred to.
