First of all, greetings to all forum members.
I will tell you a little about myself and the problems I had while learning and applying some syntheses in the forum. I think the professional underground chemists here will solve my problemsI have been examining all the syntheses shared on this forum and some points where people have problems for about 1 month and I have been quietly experiencing the potential problems they encounter. I am very interested in amphetamine and its derivatives because of the department I studied at the university. That's why I try to do research from foreign sources and get the information I want, instead of learning from idiots who have a diploma in my country and don't know anything.
I live in Turkey. Therefore, my mother tongue is Turkish. The terms you use in some transactions here are very different from us. I can't understand what you are trying to do in some syntheses. It is almost impossible to search for a term or word that I do not understand on the internet or in the forum.
I found the synthesis I wrote below on this forum. Unfortunately, our member who shared this synthesis did not share much explanatory information for young chemists
Without further ado, I will write to you, my esteemed professional teachers, questions next to the lines below / by numbering the parts I put. I would appreciate it if you could answer the questions as I numbered them.
4,8g PseudoE /1
2,5g RP
6g I2 /2
1,5ml H3PO4
oil bath
4 Hours Reflux
after reaction:
150ml DH2O /3
add NaOH PH 12+ /3-1
100ml Xylene /3-2
wash with warm, cold DH2O /4
separate funnel /5
+20ml DH2O /6
+20ml DH2O /6-1
add 35%HCL PH 7 /6-2
evaporate in heat /7
washed with cold Acetone /8
recrystalization in Isopropylalcohol with acetone /9
left in the freezer for 12 hours
filtered
MY QUESTİONS:
1: Is it pseudoephedrine that we take out and put directly from the pseudoephedrine drugs mentioned here, or is it pure? (pills that we took out of the box and crushed without any action).. If it is a drug, what drug would you recommend and does it matter how many mg it is? Pseudoephedrine (PEH) is written on some medicine boxes in our country. I guess typing PEH means it's useless for this process.
2: Iodine is mentioned here. but the writing of I2 confused me. When I asked my teacher, he said that it is an iodine compound, but he himself does not know. What does the 2 signify?
3: After the reaction, are we going to do the operations we did here in the bubble where the reaction took place, or do we need to do this in a glass separately?
3-1: As far as I understand, we were asked to raise the pH level above 12 using sodium hydroxide. If I understood correctly, just say YES YOU FOOL
3-2: If we increased the pH level in the previous article, why do we add acid again and disturb the pH balance? What is our purpose in adding this?
4: I don't understand anything done in this article please explain clearly or post an article or video where I can learn.
5: I don't understand anything done in this article please explain clearly or post an article or video where I can learn.
6: where do we add
6-1: where do we add
6:2: I think what we're trying to do here is to neutralize the mixture using HCl. (but I still don't know what mix to add the stuff here)
7: what is our purpose in doing this and what mixture are we trying to evaporate
8: What is the washing process with cold acetone? and why is it done? (I need a clear explanation of how this is done because it is a situation that I will learn for the first time.)
9: This is the question I most want clarification on. I don't know anything about it. I need a clear explanation of how it's done and why.
I think these are all the questions I need. Thank you everyone in advance for your answers. And I would also like to point out that I am trying to understand almost all the syntheses shared by our teacher G.Patton by taking notes in my notebook and working on them. I made a note on the first page of my notebook that you are my secret hero.
If one day I am arrested, I will tell all my friends about you in prison.
