Question about nitroethane synthesis

I wasn’t goin to post this but it’s Christmas tomorrow

do not use a flame and use straight pipe not zigzag this was 1937 we more clever in this day and age. Obviously flow rate needs to be spot on and temperature not exceed over 400°c propane automatic flash is 420-450°c you will be seeing god

end product you’ll get 4 nitros simple distillation required for nitroethane

last time I done it was 5 years ago sketchy synthesis

You can be safe with the flash point of the propane because the rxn mixture is supposed to be oxygen free. No oxygen, no flash. So just ensure you have no oxygen in your reaction and everything will be your way. Besides, the industrial way of propane nitration envolves pressures way exceeding the normal (8 to 12 atm) thus increasing flash point temperature anyway.

nitroI keep it at 350-400 seems good takes hours as I run it verry slow

I would like to ask about making nitroethane
K2CO3 + NaNO2 + H2O + C3H5BrO2
Is this correct?
Have you tried it? Can you provide the correct value?

Add 20g of the acid to a solution of K2CO3 in the amount of base that causes the solution to be basic to phenolphthalein. The add 20g of NaNO2--there should be approx. 100ml of solution. Place in a 250ml rb flask and distill quickly- the first 100ml will come over before the rxn takes place. Then the nitroethane comes over. Distill until no more product comes over.(don't distill to dryness)
