Hey thanks @K-Cyanide, I was still thinking if I could still save my solution but it looks like it's completely decomposed as it is now completely black. I am now looking for a vacuum distillation set to achieve this. Is there any that you would recommend? I'm not too sure how to calibrate our...

The temperature exceeded 220 and hit 280 at one point and now my receiving flask has two layers. Not sure what I’m looking at now too

I’m not too sure if it is P2P as I read in one of your threads that we are not allowed to pour in HCl without being drop wise as it will spoil our product and I’m not sure if exceeding the specified temperature would give me a different product as well. How would I know if it’s pure P2P now?

Hey Patton, sorry for the lack of information. I’ll be more specific here. I followed the steps exactly as shown in the video for this synthesis except I wasn’t able to bring the temperature down to 0-5deg Celsius on the NaBH4 addition step. I also did not add HCl in a drop wise manner but I...

Hey guys, after adding DCM and washing with NaOH, my bottom layer is green instead of red like in the video. I am gonna distill this and see if I can get any P2P but has anyone experienced a similar issue as this? Why is the colour different?

can I replace Toluene with other solvents like DCM or petroleum ether?

I was able to follow the steps until step 4, but once I start heating the solution to evaporate the toluene, the mixture turns red like this with a very dark colour. Any ideas?

Hello, just want to make sure I understand this correctly. step 2: after filtering the dark green suspension, I have a slightly green solution only with a few drop of brown solution. What layers do you mean to separate? step 3: I have to pour toluene into the aqueous layer and extract the...

I'm a little curious on what purpose the water serves in step 3? It seems to go straight through the toluene solution and stays separated.

Read about synthesizing aluminium Amalgam with HgCl2 and MeOH on your thread. Couldn't find anything related to the NaBH4 though, but I did come across a similar question in another thread. where ImOutAlso asked about Question 2 and I'm not very clear on the context. Is the NaBH4 used to...

I was told I could follow method #2 here to obtain crystalline methamphetamine, but this looks like synthesis from methamphetamine free base and NOT amphetamine free base. Can anyone verify if these steps could be followed with amphetamine free base? If not, how can I convert amphetamine to...

Thanks for the tip guys, I’ll experiment around with different ratios and see what works best. I couldn’t find in the forum regards to how I can dry up wet amphetamines though. I’m thinking of putting the wet amphs in a sealed container separated with MgSO4. Would that work? I’ve tried drying it...

I see, I’ll try using an ice bath while slowly adding the sulphuric acid on the next batch. Thanks for the insight. Do you know if the overacidified mixture is recoverable? The NaOH method does not seem to work produce any promising result.

Thanks, I’ll try that. What sulphuric acid concentration do you use? I’m currently using industrial grade 99.8% so I probably won’t be able to use 1:1 ratio with the acetone to prevent this from happening again.

Thanks Patton, I’ll try that. What sulphuric acid concentration do you use? I’m currently using industrial grade 99.8% so I probably won’t be able to use 1:1 ratio with the acetone to prevent this from happening again.

The mixture of amph free base + acetone, after adding sulphuric acid has a boiling-like reaction where the salt formed and started foaming bubbles.

Thanks for the prompt answer Patton. I did another batch and as I added sulphuric acid, after the solution stopped boiling, I got this layered solution, it looks different from the batch above. I followed the ratio of 1:1 of acetone and sulphuric acid. Do you know what this is? It’s Transparent...

I’ve followed the guidelines in AB Extraction and I’ve arrived at the end product. I’m not sure if what I have is correct as it does not look like the powder form end result as shown in pictures. Instead I have this gooey paste that I’m currently waiting to dry up. Does anyone know if this is...
