Is there any new substance that can replace 5449 (old version of sodium salt)?

Can you tell me the CAS or name of the new sodium salt?

I also want to get some and try to use the new version of sodium salt to make P2P

Misschien leuke.info om te weten over de nieuwe PMK!!

Chinese are ALL selling the ETHYL METHYL form since the ethyl is banned, they dont play when something is banned

Most probably for this;
28578-16-7 pmk ethyl glycidate


1. 50 gr wax and 70 ml dH2O and 12 gr caustic , raise the temp to 80º C , and keep it there under stirring conditions for one hour.

2. add to the mix 32,5 gr of HCL 37% and stir fot another hour keep temp@ 80ºC

3. Decant to a Sep funnel , discard the water layer and add a equal amount of demineralised water with a saturated odium bicarbonate solution swirl or shake when possiblevand let it sit for 30 minutes

4. repeat 2 x more times the saturated solution washing, discard water always and then one time only water washing.
( if an emulsion appears try brine wash)...

5. vacuum distill till all water goes (its just a small quanty who are giving the problems) and could be done in rotovap.
and you will get a dark red-brown oil.

Ik heb gehoord dat de opbrengsten beter moeten zijn dan de oude..

what are you talking? All pmk glycidates were banned in China past August, including obviously the 28578-16-7.

There are no alternatives at the moment, closer to MDP2P.

Hey mannen,

Iemand ervaring met de synthese van 3mmc? Zie vooral dat 4mmc hier op het forum voorbij komt maar zelf meer interesse in de 3mmc variant.

Nieuwe bmk poeder vervanger 5449 hoorde ik van china​

Cas 10250-27-8​

Name2-Benzylamino-2-methyl-1-propanol
CAS10250-27-8

Aan een oplossing van 2-amino-2-methylpropan-1-ol (1 g, 11,22 mmol) en benzaldehyde (1,310 g, 12,34 mmol) in DCE (15 ml) bij RT werd portiegewijs natriumtriacetoxyboorhydride (6,66 g, 31,4 mmol) toegevoegd en het mengsel werd 3 uur geroerd. Het mengsel werd verdund met EtOAc en gewassen met verzadigde waterige NaHCO3. De organische laag werd gedroogd boven MgSO4, gefiltreerd en geconcentreerd. Het ruwe product 2-Benzylamino-2-methyl-1-propanol (1,247 g, 6,96 mmol, 62% opbrengst) werd gebruikt zonder verdere zuivering. LCMS (m/z): 180,0 (M+H+).

Maar is hier al iemand mee bezig geweest
En is er een manier op fosfor toevallig

Nieuwe pmk
Cas 718-08-1

De synthese van Ethyl 3-oxo-4-fenylbutanoaat is als volgt: Monoethylmonokaliummalonaat (12,9 g, 2,3 equivalenten) werd gemengd met tetrahydrofuraan (200 ml) en het mengsel werd afgekoeld tot 5°C. Triethylamine (8,2 g, 2,5 equivalenten) en magnesiumchloride (8,62 g, 2,8 equivalenten) werden toegevoegd en het mengsel werd 3 uur geroerd bij 5 tot 20°C. Het reactiemengsel werd afgekoeld tot 5°C. Fenacylchloride (5 g, 32 mmol, 1 equivalent) werd geleidelijk toegevoegd en het mengsel werd 63 uur geroerd bij 5 tot 20°C. Het mengsel werd afgekoeld tot 5°C en 1 N zoutzuur (30 ml) werd toegevoegd. Tetrahydrofuraan werd onder verminderde druk verdampt en extractie werd uitgevoerd met ethylacetaat (50 ml). De organische laag werd gewassen met 1 N zoutzuur (30 ml), water (10 ml), verzadigde waterige oplossing van natriumwaterstofcarbonaat (30 ml) en water (10 ml) in volgorde. Het oplosmiddel werd onder verminderde druk verdampt om het Ethyl 3-oxo-4-fenylbutanoaat te verkrijgen als een lichtgele olie (5,82 g, opbrengst: 86%).

I heard Cas 718-08-1 is also Bmk and not Pmk.
But there is New Pmk which has the same melting method as the old Pmk 28578-16-7

Heb pas 5 kilo als sample gekocht. Ze willen de Cas nummer nog niet geven omdat ze bang zijn dat die ook verbannen wordt. Ik laat hier weten of het goed spul is. Meld ik me***** bij wie je kan inkopen.

Maybe a rookie question but how do people buy solvents (acetone) in bulk without being suspicious?
