Good day to everyone.
I ordered from @Vivian Rose 25kg BMK Glycidic Acid (Sodium Salt) CAS 549-12-7. The fact that she claimed that he was in stock in Europe and delivery would be fast, i can add a separate story. Briefly I waited instead of the promised 3-5 days, for a month. But I finally got it, took time to assemble a mobile laboratory and begin synthesis.
Below I will attach a photo of correspondence and photographs of the synthesis of this as it calls "BMK Glycidic Acid" (No). I also ordered a 25 kg BMK CAS 549-12-7 powder from @Simon, there will be a photo of it below.
The BMK Glycidic Acid from Vivian Rose had a vinegar smell and after heating ~ 60c acquired black, also dissolved in water for a very long time in comparison with the real BMK, and did not dissolve after 3 hours of mixing. I spent about 5-7 attempts to extract P2P, with orthophosphoric acid 85%, with diluted hydrochloric acid 15%, with a concentrated 35% hydrochloric acid. With different proportions of water, acid and temperature.
With the BMK Glycidic Acid from Simon, I immediately managed to extract dirty P2P at standard temperatures and proportions(with orthophosphoric acid 85%).
I’m not a chemist, maybe dear experts will be able to draw conclusions according to my vague indications what kind of reagent is, but the fact that this is not a BMK Glycidic Acid.
I’m not really counting on a refund, since I myself have to blame that I made a transaction without Escrow, but at least I will warn the rest for the future whether the service has a reputation or not - it is better to draw up a deal through Escrow.
P.S. The last three photos are Simon BMK. If necessary, I will also post a correspondence with @vivianrose, but I do not think that it will deny the fact of the purchase.
