Abstract
A commercial javel extract (a sodium hypochlorite solution of between 30 and 70 chlorometric degrees containing sodium chloride) has a molar ratio NaOCl/NaCl of between 1 and 6 and a density of between 1.07 and 1.22, and may be prepared by separating the precipitated sodium chloride from a concentrated javel extract (a sodium hypochlorite solution of between 70 and 140 chlorometric degrees) and appropriately diluting the solution obtained. The concentrated javel extract is prepared by reacting gaseous chlorine with sodium hydroxide in a suspension in sodium hypochlorite solution of sodium chloride crystals such that the sodium chloride precipitated by the reaction increases the size of said crystals. The sodium chloride crystals are preferably maintained in the form of a fluidized bed in the reactants, the bed being situated in a vertical reaction and crystallization vessel to the lower portion of which chlorine and sodium hydroxide are continuously introduced, part of the product being removed from the upper part of the vessel, cooled and recycled to the base of the vessel so as to maintain the fluidized bed. The enlarged NaCl crystals are removed from the lower portion of the vessel. A chlorometric degree is defined as one kilogram of a product which titrates one chlorometric degree and has the same bleaching or oxidizing effect as one litre or 3.2 gms. of gaseous Cl2.
