摘要： An improved method is disclosed for continuously purifying crude aluminum alkyls containing solid contaminants such as aluminum particles comprising passing crude aluminum alkyls into a first holding vessel, the contents of said vessel being continuously passed under pressure through a tubular filter having an upstream inner surface and a downstream outer surface, solids-containing aluminum alkyls passing through said tubularfilter returning to the holding vessel, and purified aluminum alkyls passing through the filter wall exiting through the downstream outer surface, and recovered; monitoring the solids content of the holding vessel and ceasing crude aluminum alkyl flow into said holding vessel when solid contents reach undesirably high levels, thereafter passing said crude aluminum alkyls into an alternate holding vessel and filter, then further passing the contents of said first holding vessel through said tubular filter until substantially all remaining aluminum alkyls have passed through the filter to recovery, and purging the contents of said first holding vessel before filtration is resumed.
