Abstract
Inventia se refera la un procedeu de obtinere a citratului de amoniu bibazic de calitate, reactiv, prin sinteza directa din acid citric si amoniac, caracterizat prin aceea ca acidul citric sub forma de solutie metanolica, purificata, în prealabil, prin filtrare cu carbune activ, este tratat sub agitare si racire, sub 30 degree C, cu o solutie de amoniac sau cu amoniac gazos, pîna la stabilirea unui pH mai mic de 5,5, dupa care se separa produsul format prin centrifugare sau filtrare.
