Abstract

Sodium perborat has a great role in industry as bleaching agent and is one of the main components of suntbetic detergent powder formulation. This chemical is produced by a reaction between SODIUM METABORATE and hydrogen peroxide. SODIUM METABORATE, also, is produced by a reaction between caustic soda and BORAX. In this investigation, these two reactions were studied. In reaction of preparation of SODIUM METABORATE, effect of addition time of BORAX powder, as reactant, to caustic soda in presence of three different types of AGITATORs on viscosity of reaction mixture has been investigated. The results show that in presence of anchor AGITATOR variations of addition time of BORAX, even with variation of temperature, prevents the augmentation of viscosity of reaction mixture. For reaction of prepartion of SODIUM PERBORATE, effect of addition time of SODIUM METABORATE to oxygen peroxide, in presence of different AGITATORs on SODIUM PERBORATE crystal SIZE DISTRIBUTION and their porosity has been studied. The results show that increase of addition time of SODIUM METABORATE in presence of anchor AGITATOR, increases precipitation of SODIUM PERBORATE and consequently, yield of reaction and produce low range of SIZE DISTRIBUTION even thought, porosity of product (SODIUM PERBORATE) decreases. The high porosity of product be obtained with anchor AGITATOR and augmentation of SODIUM METABORATE addition to the reaction mixture (minimum flow rate 0.5 gr/min).
