Hola a todos

¿Cómo puedo cristalizar una solución acuosa ya preparada de mef utilizando NaCl si no dispongo de harina inicialmente? Digamos, tengo una base de mef en diclorometano y voy a acidificarla en exceso de agua 135 ml por 100 mef, mientras disuelvo el mef en agua - no pongo el mef en harina, sino inmediatamente en agua

En qué momento añadir NaCl y en qué proporciones. Según la experiencia superior, el autor indica 23 gramos por 100 gramos de mef, pero tiene 100 gramos de mef disueltos en 100 ml de agua. Y mi oxidación se produce a una cifra de 135 ml por 100 g del producto.

¿Cuánto tiempo se forman los cristales en el método de la solución salina de NaCl? ¿Qué fracciones de tamaño se obtienen? ¿Cuánto tiempo debe conservarse el producto en el congelador? ¿Afecta el tiempo de exposición al tamaño del cristal?

¡Gracias a todos!

en dcm no se puede hacer así, hay que usar agua en el proceso de acidificación y luego usar, por ejemplo, ipa para iniciar inmediatamente el proceso de cristalización. Naci no es necesario en absoluto, es una tonteria. y no se puede congelar porque el cristal no saldra en forma de polvo de vidrio y cristal solamente

Brine cristalisation grom yesterday - everything happen in about one hour. But its recrystalisation of 3cmc. At the same time i maked 3 other kind of crystalisation. The biggest crystal (yes one big crystal) is in only vodka. The most beautifull is on 1 ml dh2o/1g powder, boiled few minutes in atomic generator 🤣 and later i used only ceramic lamp

Oh nice, if you break it up more it will help you remove the colouration of the crystal otherwise the acetone won't be able to penetrate the solid mass of that crystal. You could probably get that white if it was broken down more.

My latest crystal, from a failed batch which i put in a beaker and used as container to drip remainders of solvents, acids andsoforth. After some weeks i needed the beaker and while cleaning it, i found these.

Now i want to make these on purpose but how... without using loads of beakers as a waste bin :ROFLMAO:
