Faster way to make crystals

Hello, depends on what do you need (large crystals or small ones)

Faster way to make crystals

DxrkFor fastest way to make crystals you need to put the solution with 4MMC into the freezer thats the fastest way to get the crystals but they will be small.

Faster way to make crystals

DxrkCrystallization technique on the rotary evaporator (always produces a fine fraction).

 

[CristalKing]

4mmc 100g
woda 200ml
aceton 50ml
witamina c 3g

heat the water to 60 ° add 4mmc, stir until it dissolves, add acetone and add vitamine c keep the temperature at 60 °. Pour the solution into a bowl, can be glass or plastic, and in a few days at 22 ° -25 ° you will get a crystal in the form of sticks. thank you so much for your attention

Venom2021Someone has tried it ?

 

[george123]

1 give 1 ml water for 1 g powder cook and let closed in coolbox when I open is nothing crystalize after 1 day.
This must be open or closed and wait which method is good

george123Of course it will not crystalize. You have to evaporate water. Leave your solution at room temperature and let water to evaporate

4-Methylmethcathinone crystallization conditions:

- Constant temperature 22-24 ºC;​

​

- Dry air (<40% relative humidity);​

​

- Container volume;​

​

​

Simple method

Isopropyl alcohol (IPA) or ethanol solution with water is prepared in ratio 30/70, 50/50, 70/30. Proportions are adjusted according with a tasks and a crystallization container volume. Time of crystallization and crystal size depend on amount of water in solution. The more water, the bigger the crystals and longer crystallization procedure. Average proportion of mephedrone hydrochloride to water is 1 g per 2-3 ml of solvent. The solution is heated to a light boiling (small bubbles). Then mephedrone hydrochloride is added in portions so that it has time to dissolve. Next, the product is dissolved, boil for a couple minutes and the solution is poured into a crystallization dish. Plastic and glass dishes are mostly used. The solution layer with height 1-2 cm height gives a fraction with a sugar crystals size. The solution layer 3-5 cm height gives an up to 5 mm fraction. Air-conditioned boxes, fume hoods and air dryers can be used for this procedure. Wet crystals are obtained after solvent evaporation, which are well dried under dry air flow, infrared radiation (IR lamp or IR heater) or in a vacuum desiccator.​

Gradual cooling method View attachment 437

Сrystallization centers are formed in the solution, when solution is evaporated for 50% or more. To accelerate the crystallization process, the mixture is gradually cooled. A crystallization dish is placed into a refrigerator (4 ºC) for 8-12 h, then it is moved into a freezer (-17-20 ºC) for 8-12 h.​

Rotary evaporator crystallization technique (fine fraction)

Mephedrone hydrochloride is dissolved in a solvent in the proportion of 1 g per 1 ml. The solution is placed in the rotary evaporator flask and distilled. The deeper vacuum, the lower the boiling point of the solution. Large amount of fine crystals are obtained by this way.

It is possible to evaporate the solution with a hot air fan from a crystallization dish in the rotary evaporator absence case. In this case, glass or ceramic heat-resistant glassware is used. It is important to prevent overheating of the product and, as a result, its deterioration.​

Crystallization technique with rapid cooling

Mephedrone salt is dissolved in hot water in the proportion 1 g per 1 ml in a boiling hot water. Ethanol 0.5 l or other polar organic solvent is added after complete dissolving. The hot solution is poured into a plastic containers to fill ½ or 2/3 volume, sealed and cooled in a freezer at -17-20 ºC. There is a chance that the product will not precipitate out. In this case crystals are filtered and the solution is additionally evaporated.

Сrystallization method in brine solution
Sodium chloride (NaCl) 23 g is dissolved in distilled water (H2O) 100 ml. Mephedrone hydrochloride 100 g is dissolved in this brine solution, the solution should be heated for better solubility. The solution is poured into a plastic container to fill ½ or 2/3 volume and sealed tightly. Crystals are grown at low temperature -18 ºC. If the temperature is cooled below -18 ºC, the brine solution is frozen.​

Marvin Popcorn SuttonTell me about crystallization in brine, how to separate sodium chloride or calcium chloride from Mephedron? There is no information about this in your main post.

subzero013Why do you need to use this strange method? It looks dirty and ineffective. Probably I can help you with an advice? What do you want to do?

G.PattonI am interested in the crystallization method at negative temperatures. Crystallization in water at a temperature of minus 8 degrees seemed interesting, only now I could not find a freezer chamber, and at a temperature of minus 10 degrees the water itself will freeze. Here is a photo of the product obtained by this method (according to the author) - http://bbzazvqcrqtki6umyxfhni37ybttt7mkbjyxn2pgllzxf2qgyd.onion/atzccw56nma-jpeg.7537/ I don’t care what size there will be crystals, the main thing is that the process takes place in the refrigerator/freezer or in a vacuum. Can you tell you something proven and effective?

There are several method with clear explanation. Do you need something else?

subzero013u get like this crystal because your powder was pure from dirty u cant get like this crystal....

here is my result with this method. The method is quite simple and fast. but NaCl or CaCl is not needed here at all. all you need is water and 4-mmc. bring water to a boil and dissolve 4-mmc (1g per 1ml) in it. continue to boil until the surface of the solution is covered with a film. then pour the solution into a glass container with a layer of ~ 5 cm and leave it completely at rest for 10 hours. I did this at a room temperature of + 8C. after 10 hours the crystals are ready

and this is another method. dissolve 4-mmc in vodka 1g per 2.5ml. and forget about the solution for 4-5 weeks at room temperature. vodka evaporates, crystals remain in the container

ChemDamnu can use 1.7ml water and is also ok

 

[ChemDamn]

minus temperature is not a prerequisite. you can do the same at a temperature of + 20C. but the higher the temperature in the room, the more 4-mmc will remain in the mother liquor. at -8C almost all 4-mmc will fall out of solution. at + 20C about 70% will fall out, about 30% will remain in the water. but what prevents you from driving off the water and getting the remains of 4-mmc, and then repeating the crystallization process again?

ChemDamni was test now your way from dirty powder.We will see for 24h how to get.

ChemDamnFor 4-5 weeks it is too long, the crystal is certainly excellent. Have you tried to use a drying stove/cabinet for crystallization? It may turn out to achieve such a result, only in a shorter period of time.

 

[Didi]

the evaporation must be slow, the slower the better and bigger the crystals. when you use a blow dryer then you will get a crystal powder
