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!!!!!!!!

MuktikaO 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)

MuktikaIt'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.

can I use Vaseline?
MuktikaYou 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

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?
