              Metalele alcaline si alcalino-pamantoase trebuie colectate intr-un solvent inert si neutralizate adaugand 2-propanol (Cod Merck 100995), picatura cu picatura si agitand. Daca reactia este prea violenta, transformarea trebuie realizata cu tert-butanol sau octanol. Atentie: Din aceasta reactie se degaja hidrogen, care poate forma amestecuri explozive; se iau masuri corespunzatoare. Cand reactia s-a terminat, se adauga apa sub forma de picaturi; se neutralizeaza; Container D. In cazul borohidrurilor alcaline sau alcalino-pamantoase adaugati metanol (cod Merck 106008), cu agitare; in cazul amidelor si hidrurilor alcaline si alcalino-pamantoase, compusilor organci de aluminiu si staniu, se adauga 2-propanol in picaturi (Cod Merck 100995). Substantele care, de obicei sunt in forma solida, trebuie suspendate, anterior, intr-un eter. Cand reactia a incetat, se hidrolizeaza cu apa, apoi se neutralizeaza. Container D sau E. Hidrurile de aluminiu si litiu trebuie, de asemenea, distruse, prin suspendare in eter. Se dauga, picatura cu picatura, amestec 1:4 acetat de etil (cod Merck 822277) si eterul utilizat pentru prepararea suspensiei. Asigurati intotdeauna amestecarea completa (agitare)! Container A.
