Modern MDA. How do you make MDA from helional?

[kamikaze3030]

I am achieving 60% yield in the synthesis of MDA Helional + Hydroxylamine. The best way for large-scale production.

There is no fucking way you, or anyone, is getting 60% overall yields on this entire scheme from helional to MDA. This place is a shitshow. I can do consults, and would be willing to for the right price. Maybe a mod can help me help these lost fellows.

Hello friends. I have a question
1. In the final step, you use the crystallization method with a stream of HCl gas. Is that right or does it burn?

2. Amide.

100 g aldoxime is mixed with 300 mL xylene and 2 g nickel acetate, added and refluxed for 5 hours. Distill approximately 100 mL xylene and allow the mixture to cool. Amide approximately 70. The grams are separated and filtered and dried. Can be recrystallized with xylene.
=How much heat can you give?
3. Aldoxime.
If aldoxime does not harden Add more hydroxylamine and base.
How much hydroxylamine and base should I add?

thank you

Hello friend, what do you use?
What method is used to synthesize MDA?
Could you please tell me? about the synthesis process and details of your chemicals

 

[kamikaze3030]

Yes, I succeed. It is the best method to do it on a large scale. Simple and efficient. Few easily accessible equipment and supplies.

Hello friend, I have a question.
In the last step you just use
(NaOH) in case it crystallizes, right?
And the .PH value should be 7.5, right?
I don't know much about chemistry.
If I'm going to confess, it's that I don't know. After adding the substance (NaOH), what must be done to get MDA? I want to ask you Can you tell me?

 

[kamikaze3030]

My method is different from yours. I don't do it that way.

Here, don't use bleach TCCA is a lot better
