PROCEDEU PENTRU PREPARAREA CLORURII DE ALUMINIU DE MARE PURITATE
摘要
<p>Hot vapors of aluminum chloride and by-products produced in the chlorination of aluminous material to form aluminum chloride are cooled by contacting the vapors with solid aluminum chloride as the vapors exit from the reactor and before the vapors come in contact with filter materials. This cooling reduces the temperature of the vapors from an initial temperature of about 600 DEG -800 DEG C down to about 300 DEG -350 DEG C thereby preventing or inhibiting attack of the filter materials by the hot vapors.</p>
