Synthesis of Acetaldehyde using Sodium Dichromate
I understand that acetaldehyde or ethanal can be synthesized using ethanol and a sodium dichromate oxidant dissolved in sulfuric acid, but won't the
product of acetaldehyde in turn be oxidized into acetic acid by extra sodium dichromate. Are there any ways to get around this?

distill off your product as it is being formed and avoid using excess dichromate.

Would adding either the dichromate or ethanol dropwise help as well?

i doubt it, when i made ethanal i simple put all the reagents in a RBF and distilled and then distilled the crude product again to obtain ethanal in
good yield.
