I ordered a test batch of new bmk. Now I have been told by the seller afterwards that the conversion to p2p would work with NaBH4/citric acid. Does anyone have experience with this case? Or an alternative route for the conversion for this case?
Hey no, I have a white powder. And I processed it according to the dealer's instructions, only instead of NaBH4, I used NaHO. After an hour at 95°C, yellow oil rises to the surface. Then I should add citric acid and heat for another hour at 95°C. After this hour, unfortunately, it doesn't smell a bit like p2p. And as soon as it cools down, the entire oil crystallizes into a hard lump. What could be going on, or does anyone have advice on how I can effectively convert it?
BMK methyl glycidate (CAS 80532-66-7) can be converted to P2P via hydrolysis followed by decarboxylation. The NaBH4/citric acid method is unconventional for this route - typical approaches use acid or base hydrolysis (e.g., HCl or NaOH) to yield the intermediate, which then decarboxylates to P2P. Alternative routes include using H2SO4 or enzymatic hydrolysis. Proceed with caution and verify reaction conditions, as improper methods may lead to low yields or side products. Always prioritize safety and legal compliance.
Thank you for the information, the problem is that it is not a real bmk (CAS 80532-66-7). It's one of those new bmks, a CAS was also mentioned but can send a personal one if needed. It is not water-soluble, has a pH value of 5. What I also noticed is that there is no foaming when adding citric acid, so no decarboxylation has taken place. I suspect there have been some issues with it.
