Hello everyone!
How can I crystallize a ready-made aqueous solution of mef using NaCl if I didn't have flour initially? Let's say, i have a base of mef in dichloromethane and I'm going to acidify it in excess of water 135 ml per 100 mef, while dissolving mef in water - I do not put mef in flour, but immediately in water
At what stage to add NaCl and in what proportions. According to the upper experience, the author indicates 23 grams per 100 grams of mef, but he has 100 grams of mef dissolved in 100 ml of water. And my oxidation occurs at a figure of 135 ml per 100 g of the product.
How long do crystals form in the NaCl salt solution method? What size fractions are obtained? how long should the product be kept in the freezer? Does the exposure time affect the size of the crystal?
Thank you all!

on dcm you can't do it like that, you need to use water in the acidification process and then use, for example, ipa to immediately start the process of crystallization. Naci is not needed at all, it's nonsense. and you can not freeze because the crystal will not come out in the form of glass and crystal powder only
and later i used only ceramic lamp
