im bout to atempt the sodium borohydride reaction but have a few concerns regarding the amine i need. I have no way of obtaining Amonium acetate but have shit loads of amonium sulfate. I know i can drip NaoH onto it and buble it into methanol (cold) and use the amonium/methanol solution but i havent seen any info regarding this and for a silly qustion can i use the amonium sulphate as is ???????? Abviously i want MDA and its Amonium Persulfate wich isnt much diferance or is it..........

You are going to make MDA using sodium borohydride as the reducing agent? And most people thought that sodium cyanoborohydride was required!

To paraphrase an engineer joke:

Yes, drip concentrated NaOH onto ammonium sulfate, and lead the gas into chilled methanol to get a methanolic ammonia solution. This can then be used together with a drying agent, MDP2P and NaBH4 to produce MDA. You cannot use ammonium persulfate here.

yes i didnt think you could use the sulfate as is. So for a 500g batch of MDP2P i should have atleast 1kg of amonium in methanol and the drying agent should it anhydrous epson salts??

Just an idea: maybe you should use the search engine, do some small scale experimentation first and then post a detailed writeup before trying industrial scale production.

the 2-1 ratio of amonium to MDP2P is taken from the NaBH4 write up im just replaceing amonium acetate with the amonium solution but im not sure about correct ratios. I did not think that 500g would be clasified as industrial but maby 10kg+. and is a drying agent absolute necesary with out too much loss in yield
