Acetone harmful to the production of [(iPrO)3Al]?
It is well known that aluminum tri-isopropoxide [(iPrO)3Al]can be obtained by reacting aluminum powder with isopropanol. However, the yield of such
reaction is found to heavily decrease when >0.1% acetone is present in isopropanol.
Is there any scientific explanation for this unfavorable result?

Can you provide references stating this decrease in yield?
I see no reason why propanone would interfere with the reaction other than the propanone being reduced by the isopropoxide formed howver if >0.1%
amounts are present then tis should be insugnificant?

Fine. Thank you for your kind reply.
The phenomenon mentioned above was first detected by a technician on duty. Then we found that there are no reported documents that can exactly support
this point. I wonder whether it is some other factors that cause the drop of yield, although the technician still sticks to his judgment.

That would be the meerwin-pondorf-verley reduction...and the products would be isopropanol and acetone. Mechanistically, this should have absolutely
no effect on the production of isopropoxide. Is there an activator being used to get the aluminum to react that might be effected by having acetone
around?
