Abstract
Procedure for the obtaining of sodium tripolyphosphate with high percentage of isomero i from phosphoric acid via humeda. Consists in the neutralization of phosphoric acid via huneda with alcali at 50 per 100 to a ph of 4.5-4.7, with a na/p ratio greater than 1, in a first stage; rebose to a second react, where neutralizes with alcali up to ph 7.1 and na/p relationship between 1.5 and 1.7; filtration in rotary vacuum filter; adjustment of the na/p relationship with a basic salt of alkaline positive cation and calcination in rotary oven to about 500 c. The temperature of neutralization in the two stages is maintained at 90 c. This composite has applications in the textile industry, paperwork, of portland cement and as dispersant of coloring and pigments. (Machine-translation by Google Translate, not legally binding)
