A process for the preparation of percarborato coated with a Sodium borate.

摘要

Process for the preparation of sodium percarbonate coated with borate.Consists of: a) reacting with Hydrogen peroxide, Sodium carbonate, followed by dehydration to produce Sodium percarbonate in a Wet condition, with a Moisture content of between 7 and 18; (b) mixing Wet Sodium percarbonate obtained with an agent recubrimien To containing borateFor this Agent is absorbed by the sodium percarbonate; and (c) Drying the mixture thus obtained at a temperature of between 40 and 160jc. The amount of borate in the coated Sodium percarbonate borate is 0.04 to 10 (weight / weight expressed as Boron Sodium percarbonate, calculated on the dry and / or Taman Particle borate between 50 and 300 microns.It has application as a Detergent.
