Herkese merhaba!

Başlangıçta unum yoksa NaCl kullanarak hazır sulu bir mef çözeltisini nasıl kristalize edebilirim? Diyelim ki, diklorometan içinde bir mef bazım var ve onu 100 mef başına 135 ml su ile asitlendireceğim, mef'i suda çözerken - mef'i una koymuyorum, hemen suya koyuyorum

NaCl hangi aşamada ve hangi oranlarda eklenmelidir. Üstteki tecrübeye göre yazar 100 gram mef için 23 gram diyor ama 100 ml suda çözünmüş 100 gram mef var. Ve benim oksidasyonum 100 g ürün başına 135 ml gibi bir rakamda gerçekleşiyor.

NaCl tuz çözeltisi yönteminde kristaller ne kadar sürede oluşur? Hangi büyüklükte fraksiyonlar elde edilir? Ürün ne kadar süre dondurucuda tutulmalıdır? Maruz kalma süresi kristal boyutunu etkiler mi?

Hepinize teşekkür ederim!

dcm'de bunu böyle yapamazsınız, asitlendirme işleminde su kullanmanız ve ardından hemen kristalizasyon sürecini başlatmak için örneğin ipa kullanmanız gerekir. Naci'ye hiç gerek yok, bu saçmalık. ve donduramazsınız çünkü kristal sadece cam ve kristal tozu şeklinde çıkmaz

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:
