Well, ask me here.
Any questions?

Is it ok to write in Russian ? Maybe, now i am first member from russia, but we have nice (and very old) forum: https://hyperlab.info/
help needed!
when mixing these elements an explosion occurred (4mmc)
4'-Methylpropiophenone - 100g
Benzene - 400 ml
Bromine (Br2) - 100g
then everything in the house was washed and washed, the splashed areas were painted, active ventilation continued for more than 10 days, but the pain in the eyes did not stop completely...
Now I am repainting all the walls and ceilings, changing the flooring!
Do I need to get any air filters?
Plus any other information please!!!!!!!!

O Man!) I directly recognize myself in your mistakes!! 
I had this fatal error with 100 pseud /I2 /P
The ceiling was impossible to clean. I had to cover it with plasterboard.
And your bromine won’t wash off either!
This was a good lesson for me
DO NOT use chemistry in a residential area!!!
An ozone generator will help you solve your odor problem.
Ozone neutralizes tear chemicals. (lachrymators)

what to do if steam escapes through the joint between the reflux condenser and the flask? The dimensions are the same nothing seems to come out through the gas outlet hose

It's good practice, essential actually, to use grease on the joints. Food-grade silicone grease is what I use. It costs practically nothing.
I also mention that if you are doing a reflux, its important there is an outlet for the pressure that builds up, otherwise bad things (pressure explosions) can occur.
I know very little but I do know this. Hit me up if more questions.

You can but when it gets hot it turns to liquid that could drip into your RM potentially ruining it. I use lip balm. I have a shit ton of them around (ChapStick) it melts a little higher and the little container is convenient. I just rub it on the male side about 2 lines, and twist as you put it together to spread it. For vacuum dist. I have actual vacuum grease which is expensive but 1 pea sized amount is plenty for a joint so it goes a long way
1.2D: Greasing Joints
Ground glass joints are manufactured to fit quite well with one another, and yet they are not perfectly airtight. In some situations (e.g. when using reduced pressure inside an apparatus), grease …
chem.libretexts.orgYes, I think Vaseline would be fine.

bbgate.complease tell me, in the step From 9:03 to 11:33, I washed 3 times with 200 ml of 5% solution, now can I proceed to what is written in blue text?
When finishing A-oil what’s the best solvent to use?
1. acetone
2. DCM
3. Petroleum ether
4. D Ether
5 IPA
6 methanol
7. DI water or distilled water… can it just be mixed with water adding acid solution till the water tests ph7. Separate and evaporate water to get your finished product?
Do you dilute it 1/1?
Magnetic stirrer or Glass rod?
What’s the best PH?
Goal is to obtain the cleanest, highest purity and nasal friendly amph sulfate for myself. Not for re sell purpose. I do not have access to be able to do vacuum distillation on the oil so if there’s another process to purify it I’d be interested in knowing.
Any advice is most appreciated!

Why don't you read a dedicated topic? There are answers to your questions...

I have searched but haven’t found all the answers I needed. Seen lots of mixed opinions. None gave me confidence enough to move forward. Obviously I haven’t looked in the correct way.
Need help with a synthesis:
I am planning to synthesize N-Ethylpentedrone.
Now the route is the same as by a-pvp synthesis, but instead of pyrrolidin we will use ethylamine for the amination. Is it possible to use ethylamine hcl 99% or has it to be a solution?

You need your ethylamine as freebase to react with the nucleophile, im an ex chemist and by small tax i can help you throw all the synthesis, i have made NEP numerous times
Is there a section on the site for me to rant about anything and everything. Like my own special little blog corner to just vent about my chemistry failures, disinformation findings and attract like-minded souls on this site to share real-life, real-time chemistry tips?
how to tmake MDMA by using pmk anyone please tell me the whole process
