Abstract
Solutions of per-compounds, for example, sodium perborate, are stabilized by treatment with silica gel. The solution may be merely left standing in contact with the gel and then decanted, or it may be agitated intermittently or continuously with the gel and filtered, or it may be filtered through a bed of the gel. The same batch of gel may be used for the successive treatment of many batches of solution. Its activity can be restored by treatment with a strong acid, e.g. concentrated hydrochloric acid, washing and drying say at 100 or 110 DEG C. Powdered gel is preferred to granular, examples showing the greater stabilizing efficiency of the former in the case of a 2 per cent sodium perborate solution. Specification 282,302, [Class 1 (iii)], is referred to.
