so order carefully, because the authorities are watching. I did not know . thank you very much . I will try to make it ... but it would be better to buy it. Chinese partner wrote $30 / liter, with delivery. is this a good price?

Formamide 75-12-7 is what is needed. Aqueous solution is not good , I think . Does anyone know where I can buy it in Europe? I haven't found it yet

Hello. Is 37% formamide suitable for synthesis? this is all I found in our country.

6 liters of Ipa at the beginning of the synthesis, 4 liters for layer selection. it is not necessary to add 8 liters at the same time. I use Methanol instead of IPA, the final product will smell less of alcohol. But because of this I can't separate layers (metalon can't do it, so when it asks...

I'm sorry, I've messaged you several times, please delete it..

thank you, it became clear. I knew which layer, but I couldn't explain to myself why that layer?? 😄

If I understand correctly, is the top layer a free base? yellowish oily appearance and 70% of the mixture. and the lower one is denser.

about 2 minutes and two layers are formed, I leave it alone for 30 minutes. 1754g nabh4 1000g p2np 100g cucl2

7. Steps . Which layer do I need? After adding ipa, 2 layers are formed. top layer transparent, clean, slightly oily surface. lower layer white dense jelly. it says Ipa's density changes and separates from the water layer. its density changes, could it mean that it has become a jelly and...

I want almost 1 kg of finished product. can I make it 3x the amount of reagents?

I followed the description here. observing exactly everything. Ipa evaporates, I pour out a mixture from rotovap, the oil starts to freeze, a change takes place: there is no smell of alcohol, but it will be in a jelly state. I understand that the free base needs alcohol to precipitate.

I didn't sleep all night. what my friend wanted to collect was 2 x 1 liter of oil, it did not contain IPA or other alcohol products. the IPA was completely evaporated (rotovap). I did it so that the oil does not smell of alcohol. in both cases he tried to precipitate it without alcohol. he...

a vessel p2np , nabh4, cucl2 ---> a oil I made two syntheses over the weekend. I followed everything step by step. Today I wanted to try it out (acetone and sulfuric acid). After adding sulfuric acid, the mixture just turned blue and the reaction stopped. What could be the problem? Has...

I finally managed to make a-oil. the third time was successful. I am a complete amateur. I am now preparing a 1kg p2np route. I will post pictures in a few hours. I'm very happy if someone needs help, I'm happy to help with oil synthesis. I can explain it in amateur language 😀

I use a double jacketed reactor. with cooling equipment. top mixer. I'm just a beginner, I'm doing my third synthesis. p2np, nabh4, cucl2 route . I want to make oil

but I'm clueless 😄 so mixing is fine. I wasn't sure, but thanks for the answer. I mix it 😄

is it good if I mix it? 100 rpm. the english is bad sorry
