Abstract
Inventia se refera la un procedeu de obtinere a acidului gluconic sub forma de solutie apoasa de concentratie 50%, din produsul de oxidare chimica sau electrochimica a D-glucozei, conform careia, gluconatul de calciu brut dupa filtrare si spalare este dizolvat în apa distilata la 90....95 degree C, pentru a obtine o solutie 9...10%, care prin filtrare pe strat filtrat este purificata de excesul de carbonat de calciu, iar dupa tratare acestei solutii cu 90% din cantitatea stoichiometrica de acid sulfuric oleum de 60....90 degree C racire, sedimentare si filtrare sulfatul de calciu, solutia de acid gluconic; gluconat de calciu (9:1) rezultata, este trecuta pe coloana de schimbatori de ioni cu un cation pentru retinerea totala a restului ionilor de calciu si eliberarea solutiei de acid gluconic care prin concentrare rapida la 40 degree C este adusa la concentratie de 50%.
