The exact procedure from:

was followed with the exception of substituting Al powder for foil. The addition of 3ml HCl and 1g Al gave no reaction whatsoever, after an additional 6ml HCl and 2g Al were added over the course of 2 hours, a violent reaction took place for about 30 seconds, where temps rose to 80*C, and most of the ethanol was boiled off.
Additional ethanol was added and the procedure continued. Upon basification, the resulting supernatant was a dark reddish colour rather than the described yellow. What went wrong?
