@Rua Hello, if you want to get NEP hydrochloride salt powder or crystals, you need you use HCl gas or HCl acid anyway.

Ethylmine aqueous solution cas no ??

Ethylmine Aqueous Solution Cas

For those who think it's easier to annoy you than to Google 'Ethylmine aqueous solution cas' themselves.

Hello @G.Patton I will use hydrochloric acid I think I need to use methylamine 40%. I need to add it drop by drop during synthesis. How many degrees should I keep the temperature while adding?

instead of ethylamine ethyl acetateCan I use it?

Hello. Are the proportions shown correct? 1KG
● 2 bromovalerophenone ~770 ml
● ethylamine ~640 ml

Ethylmine aqueous solution %70
was added dropwise to 1-phenyl-2-bromopentan-1-one (72.34 g, 0.3 mol) in 500 mL round bottom flask. this is the process ??

I realy like n_ethylpendotrone
Today i cook again
Have some problem with yield but quality is amazing

 

[olduser]

hello, can you precise what yield you reached and what quantity of a-bvp did you used ? I struggle to reach more than 40% yield, is that your case ?

 

[طهرانmobster]

Hello
Yes
In last synthesis i use about 100 gr of valerophenone and get 30 gr of nep
Quality is perfect but i try to reach 50%yield

 

[olduser]

ok, lemme know if you discover anything interresting

I’ve made some changes to the method and I’m trying out a few new ideas. Today, I conducted the fifth experiment and I’m waiting to see the results. I’ll update you with the details soon.
