Abstract
Procedeul pentru obtinerea fosfatului dicalcic pasta, din srot degelatinat, conform inventiei, cu o solutie de acid sulfuric, la temperatura de 80 degree C, sub agitare timp de 2h, dupa care, oprindu-se încalzirea si continuîndu-se agitarea, se adauga apa pîna la atingerea, se adauga apa pîna la atingerea, se adauga apa pîna la atingerea unei concentratii de 12%, iar dupa înca 1h de agitare, amestecul de reactie se lasa în repaus si se decanteaza solutia fosforica care, dupa separare, este tratata cu lapte de var pîna la 1 pH neutru rezultînd fosfat dicalcic care, în final, este separat dupa decantarea apei supernatante.The process for obtaining dicalcium phosphate from the degelatinized slurry according to the invention with a sulfuric acid solution at 80 ° C with stirring for 2h, after which the heating was stopped and the stirring continued, water to the touch, water is added until reaching, water is added until a concentration of 12% is reached, and after another 1h of stirring, the reaction mixture is allowed to stand and decanting the phosphorus solution which after separation is treated with limed milk to 1 neutral pH resulting in dicalcium phosphate which is ultimately separated after decanting the supernatant water.
