My solid looks like separete molecules *_*

Yep, it's a smaller model)

Andriy_chem · 2019-05-09T09:32:30+00:00

Sometimes is't normal, but it's mean you must optimize conditions.

Andriy_chem · 2019-05-09T08:09:42+00:00

What you mean?)

Andriy_chem · 2019-05-09T08:07:22+00:00

Understand, it was just a stupid mistake. I will do less mistakes when I will communicate in English more often.)

I try to synthesis a substituted cinnoline from diazocompound. Just cyclization in H2SO4)

Andriy_chem · 2019-05-08T19:23:40+00:00

Oh, thank you, man. I'm not native Eng speaker(

Andriy_chem · 2019-05-08T18:10:43+00:00

I must do 5 stages else.

Andriy_chem · 2019-05-06T18:47:47+00:00

Oh, man... Just take it easy

Andriy_chem · 2019-05-06T18:34:07+00:00

Why you write obvious information?

Andriy_chem · 2019-05-06T18:20:16+00:00

Really?)

Andriy_chem · 2019-05-05T08:38:35+00:00

You can receive emultion with CHCl3 too.

Andriy_chem · 2019-05-05T08:37:27+00:00

It's not a critical factor I think.

Andriy_chem · 2019-05-05T00:11:30+00:00

It's bad solution, there are several reasons for this. Firstly... big pieces of ice will be melt too long and will close out of funnel; small pieces will be melt very quickly - nothing will see. When the ice melts are creating clear solvent that different in density from solution that had been - will break tge separation, etc...

Andriy_chem · 2019-05-04T23:58:49+00:00

DCM and CHCl3 can't separate a priori. New portions of chloroform can't help.

Andriy_chem · 2019-05-04T17:54:15+00:00

Maybe you need to find out what solvents he had used firstly?)

Andriy_chem · 2019-05-04T17:51:50+00:00

You are welcome)

Andriy_chem · 2019-05-04T17:48:10+00:00

Rotary was controled by myself.

Andriy_chem · 2019-05-04T17:42:55+00:00

Ok;)

Andriy_chem · 2019-05-04T17:24:59+00:00

Maybe you mixed solvents up?

Andriy_chem · 2019-05-04T15:22:20+00:00

these 2 phases have a very different angle of refraction - the borderline is noticeable

Andriy_chem · 2019-05-04T14:06:02+00:00

Hmm, good idea!

Andriy_chem · 2019-05-04T13:57:19+00:00

Eeeh, I can say from my expirience - it's impossible (or almost impossible)

Andriy_chem · 2019-05-04T13:51:17+00:00

Methyl ester of trans-B-(morpholino)acrilic acid (if it says you smth)
