Abstract
Inventia se refera la un procedeu de obtinere a rutilului sintetic, care se caracterizeaza prin aceea ca, se aduc în contact sub agitare concentratele ilmenitice fin granulate, cu acid clorhidric 20,3-26% concentratie, în raport de greutate de 1:6, dupa care masa de reactie se fierbe sub reflux, timp de 6-9h, cînd se separa prin distilare jumatate din cantitatea de acid clorhidric introdusa initial, se raceste la 30-40 degree C, se îndeparteaza prin filtrare clorurile ferice solubilizate, si insolubilul se spala cu acidul clorhidric rezultat prin diatilare si cu apa, la un raport total L:S de 1:1.
