Abstract
Inventia se refera la un procedeu de preparare a sitelor moleculare zeolitice, prin sinteza hidrotermala din solutie de silicat de sodiu si de aluminat de sodiu, care în scopul reducerii continutului de fier pîna la 10...35 ppm, foloseste ciclohexilamina, ca agent de complexare a fierului, care se adauga fie solutiei de silicat de sodiu, în acest caz complexul format fiind separat din solutia de silicat de sodiu prin decantare, înainte de contactarea acesteia cu solutie de aluminat de sodiu, fie în mediul de sinteza, caz în care complexul este îndepartat, dupa efectuarea cristalizarii, prin filtrare, odata cu solutia muma si apele de spalare.
