anhydrous lithium perchlorate is prepared by heating the commercially available anhydrous material or its trihydrate at 160 °C for 48 h under high vacuum (P2O5 trap).

crystd from water or 50% aq MeOH.
Rendered anhydrous by heating the trihydrate at 170-180 OC IN AN AIR OVEN.
RECRYSTD TWICE from acetonitrile and again dried under vacuum.
一往无前
