I have diethyl oxalate unnecessarily, and I want to make alcohol from it by basic hydrolysis. I will use 200 g of diethyl oxalate, and according to the stoichiometry I should use 109.4 g of NaOH (I will use a slight excess of about 50 g, so 160 g in total). Then I will reflux for about 2 or 3 hours and distill off the alcohol. The question is, how many ml or g of water should I use to dissolve of 160 g NaOH? I've read that a NAOH solution should always be used for hydrolysis, but I don't know how much.
Thank you very much, chemists. Lukáš S.
