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 guys,

Anyone experience with the synthesis of 3mmc? See mostly 4mmc passing by here on the forum but more interested in the 3mmc variety myself.

Cas 718-08-1
Cas 10250-27-5
These are the new cas numbers for bmk
At least this is what I got from Chinese companies

 

[chef learner]

Have you tried using the phosphoric acid method to convert P2P successfully? Conversion rate %

 

[Cryptos82]

What are the return please my friend?

New bmk powder replacement 5449 i heard from china

Cas 10250-27-8

Name	2-Benzylamino-2-methyl-1-propanol
CAS	10250-27-8

To a solution of 2-amino-2-methylpropan-1-ol (1 g, 11.22 mmol) and benzaldehyde (1.310 g, 12.34 mmol) in DCE (15 mL) at RT was added portionwise sodium triacetoxyborohydride (6.66 g, 31.4 mmol) and the mixture was stirred for 3 hours. The mixture was diluted with EtOAc and washed with saturated aqueous NaHCO3. The organic layer was dried over MgSO4, filtered and concentrated. The crude product 2-Benzylamino-2-methyl-1-propanol (1.247 g, 6.96 mmol, 62% yield) was used without further purification. LCMS (m/z): 180.0 (M+H+).

But has anyone been working on this
And is there any way on phosphorus by chance

New pmk
Cas 718-08-1

The synthesis of Ethyl 3-oxo-4-phenyl butanoate is as follows: Monoethyl monopotassium malonate (12.9 g, 2.3 equivalents) was mixed with tetrahydrofuran (200 mL) and the mixture was cooled to 5°C. Triethylamine (8.2 g, 2.5 equivalents) and magnesium chloride (8.62 g, 2.8 equivalents) were added and the mixture was stirred at 5 to 20°C for 3 hours. The reaction mixture was cooled to 5°C. Phenacyl chloride (5 g, 32 mmol, 1 equivalent) was added gradually and the mixture was stirred for 63 hours at 5 to 20°C. The mixture was cooled to 5°C and 1 N hydrochloric acid (30 ml) was added. Tetrahydrofuran was evaporated under reduced pressure and extraction was performed with ethyl acetate (50 ml). The organic layer was washed with 1 N hydrochloric acid (30 ml), water (10 ml), saturated aqueous solution of sodium hydrogen carbonate (30 ml) and water (10 ml) in sequence. The solvent was evaporated under reduced pressure to obtain the Ethyl 3-oxo-4-phenyl butanoate as a pale yellow oil (5.82 g, yield: 86%).
But has anyone been working on this
And is there any way on phosphorus or lemon

 

[lucas_cash]

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

 

[herman]

Yeah can't find it well on google either and chinese are not very clear
But do you already know the new cas for pmk powder

 

[lucas_cash]

Just bought 5 kilos as a sample. They don't want to give the Cas number yet because they are afraid it will be banned too. I'll let you know here if it's good stuff. Will immediately report who you can buy from.

 

[Houdini1]

Any updates on this?

 

[lucas_cash]

Delivery takes 7-20 days. Didn't get the package yet. Will update as soon as I get it.

 

[Houdini1]

Legend bro!

 

[EpicQuest_246]

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

 

[Tovenaar]

Order in poland they come deliver it in bigger amounts, small amounts just buy in portions in local store

hello is there any word on the new pmk cas number or supplier
