Hej alle sammen!

Hvordan kan jeg krystallisere en færdiglavet vandig opløsning af mef ved hjælp af NaCl, hvis jeg ikke havde mel oprindeligt? Lad os sige, at jeg har en base af mef i dichlormethan, og jeg vil forsure den i overskud af vand 135 ml pr. 100 mef, mens jeg opløser mef i vand - jeg lægger ikke mef i mel, men straks i vand

På hvilket tidspunkt skal du tilføje NaCl og i hvilke proportioner. Ifølge den øverste erfaring angiver forfatteren 23 gram pr. 100 gram mef, men han har 100 gram mef opløst i 100 ml vand. Og min oxidation sker ved et tal på 135 ml pr. 100 g af produktet.

Hvor længe dannes der krystaller i NaCl-saltopløsningsmetoden? Hvilke størrelsesfraktioner opnås? Hvor længe skal produktet opbevares i fryseren? Påvirker eksponeringstiden krystallens størrelse?

Tak til jer alle sammen!

på dcm kan du ikke gøre det på den måde, du skal bruge vand i forsuringsprocessen og derefter bruge f.eks. ipa til straks at starte krystalliseringsprocessen. Naci er slet ikke nødvendigt, det er noget vrøvl. og du kan ikke fryse, fordi krystallen ikke kun kommer ud i form af glas og krystalpulver

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:
