Im running the same process at the same stage. Don't expectuch help from the team here. They seem to have abandoned this write up. I think a lot of write ups are just copy pasted.
jokerr
Consider, that MEK and Benzaldehyde have different molecular weight and density. Therefore 100ml of MEK is not 100g. This only an issue later when you go to add 100g of h202(50%)
There are several measures in this write up where one side of the reaction is stated in grams and the other in MLS. H2O2 I stated in grams of a 50/50 mixture. So you have to account for the water and the peroxide when calculating the MLS from weight. Unless your going to start weighing liquids.
Let me know how you go, when I did .1M reaction I ended up with such poor yields that i couldn't extract the p2p from the tar crap. This write up doesn't really inform you much along the way of what to expect. You can the impression of just extract and distill.
Let me know how you go extracting the MPB tomorrow. Did your Rx mixture go bright red?
hello masters,
I started from the first stage.
I added 100 g of benzaldehyde and 100 ml of mek, cooled it to 0 degrees and gassed for 1.5 hours.
then I stirred it for another 1.5 hours at room temperature and it will rest overnight.
continue operations tomorrow.
