Yes, I also want to know, is ethyl acetate good in this, or ...?

46 g benzald. (~95% [43 ml]) + 36.8 g MEK (29.4 ml) + 45 g hydrochloric acid (18% [41 ml]). 100°C to 115°C degrees. Time: 4 hours. After washing: About 45 ml of crystal solution.

I don't understand why you gas it.

I haven't done that exactly. I have to be at work, so mostly I do my synthesis at night time...

What OrgUnikum will say about this, I don't care, but I have papers, that shows that ZnCl2 and AlCl3 are good catalysts in Leuckart reaction.

Can I use anhydrous copper sulfate in the drying tube with cotton?

Now with my new heater/stirrer, everything is going with much less hassle. Thank you all.. be back soon..

Now I just have to tell you this. I don't want a lecture how things work in paper. I want to know how they work in real life, in real actual synthesis. I know how to do Leuckart, and I've done it about 10-15 times now. And failed, because my "P2P". Now I just don't want to ***** things up. How...

You did the bubbling, did you? :) Do the heating with hydrochloric acid, and you'll get better results.

Yes, I also support, this whole synthesis works very well.

wael: Do you know why they use DCM in almost every "amine" extraction, even though there is a risk that the amine-containing product will be spoiled by the chlorine in dichloromethane? Is it about the di-polarity of the solvent? If so, why not ethyl acetate rather? Bad for hydrogenations, but...

Wow, I didn't know that! :) Yes, that is the purpose on condensers. I was asking about those pressures with different condensers, because I haven't read anywhere about different pressures, but now I'm thinking yes, I think there is little bit more pressure at 160 C, with spiral condenser than of...

OrgUnikum: I didn't get it now. Should I use very cold water, that I use, or should I put "not-so cold" water in the condenser? And: Should I use: That condenser that have spiral in it, or fractional column (made so it haves some shards inside), or straight and wider condenser, or do I use my...

Can you tell me if the mixer piece was the wrong size, or why it bounced around when I tried to mix? I put a new stirrer piece in the new 500ml rbf. I was preparing diphenidine from deoxybenzoin and piperidine. I'll try again because it's a really simple synthesis. At least on paper..hehh. It...

Yes, I have 85% formic acid, and from ammonium formate, there comes the water, wich have to be removed. The waters that come from the formic acid and ammonium formate must be removed. That's why I use hand-warm water for 2-3 hours in the condenser. When I notice that the melted formate and P2P...

I have to tell you OrgUnikum that of course I didn't think you had all the answers. But that's why it is good to read books, patents, publications from literature etc etc.. Just to you to say the Leuckart reaction doesn't work with lower temperatures, and I've read books, and books (Moore...

First of all, now when I read third time your post, I got it. The "ingersoll reagent" works, but I always put formic acid in there, of course, because I had no clue about "Ingersoll-reagent". And my 85% formic is of course 15% water, so there it went wrong. I have to ask you OrgUnikum: I have...

I noticed that when I first started making formamide in previous reactions, I did it exactly according to the "Inngersoll reagent", i.e. in temperatures of about 170 degrees C and then for 2 hours in temperatures of 150-160 degrees C and finally only in temperatures of 140 degrees C, and I...

Thank you OrgUnikum, for making it clear to me that UF talks a lot of crap in its books, because I trusted them completely, especially when I was at the very beginning, and they were the only books I could find on the subject, before I found this good forum on this very same and many more...

Yes, I think I've read almost the whole Rhodium about P2P and Leuckart. No, i don't read Reddit. I was annoyed the Fester wrote hes books probably too wired from meth, and that's why they were quite difficult to read. But I give him the credit that when i read those, I was also interested to...
