Abstract

Procedure for the obtaining of tetrasodic pyrifosphates of average purity from neutralized sodium phosphate. Consists of the transformation of sodium phosphate ph 5.5 and relationship na/p less than 1 in a sodium phosphate ph and relax na/p equal to 2, in two reactions in continuous; by addition of alcali, to a temperature of 90c and continuous agitation in the proportion of 50 per 100, in a first stage, which is given a relacon na/p of 1,5-1,7 and a ph of 7, 1, followed of filtration and addition of alcali, in a second stage, up to a relationship na/p of 2 and ph 9, concentration to empty and calcination. This composite has applications as an additive in textile treatments, dispersant in the manufacture of coloranrtes and pigments, degreaser in the clipping of plates and in the formulation of soaps and detergents.
