DCM shortages


Has anyone here heard about a dcm supply chain shortage for next year? I've been hearing rumours, but nothing conclusive. My current understanding is that natural gas from Ukraine was the main feedstock, and that's dwindling. Same thing with liquid helium for the nmrs at work.



There wasn't a fire, we just had an uncontrolled rapid oxidation event at the power plant.

No problem getting DCm so far, but liquid helium is getting harder to find, and will only get worse I think.

But we have had problems getting many random chemicals, but often another source will have it. But it keeps happening, from hexane to ethyl acetate to THF, different each month. But we have been lucky enough to get everything eventually. We couldn't get cloves for almost a year when covid started. Amazingly enough, Enamine (in the ukraine) has reopened at least for a short time...

I dont know where you are but a couple of years ago (it was then already hard to get from chemical suppliers at that time) I got a five liters can from a boating / windsufring company on eBay that also sold all kind of fibers, resins, platicizers etc. They even sold 10l drums !
If you want to make stocks maybe you could look for similar businesses in your area or contact them through eBay. I made great contacts, even people I would now call friends like this. Leonid in Ukraine certainly isnt shipping chemicals at the moment.

Since I use very small quantities, the gallon or so I had has lasted quite a while. I have been substituting chloroform (which I can make) wherever practical.

I've bought this 25 L package more than 1 year ago at a price 55 EUR, few months ago I saw the price was almost 100 EUR and now more than 150 EUR and it is even out of stock (sold out)

If there is a heaven, it seems not to be materially based. Does chemistry exist there and if yes, how does it look like? Are there good souls well supplied with laboratory equipment, glass, chemicals and information?

guys- this might become a very long term problem

http://www.sciencemadness.org/talk/files.php?pid=672164&...
check 541

however, im hearing that MEK has very low solubility in water if Na2CO3 is added to the solution- otherwise ethyl acetate should not be hard to produce in workable yields, ether is also well doable, despite having about 6g/100mL solubility




~25 drops = 1mL @dH2O viscocity - STP
Truth is ever growing - but without context theres barely any such.

Not sure where you're at, but if the U.S.A. like me, this is a Canadian company that ships here:

A bit expensive, but it's the only place I found since the government started making companies take it out of their products.

40 € for 5L is the current DCM price. I must have four litres left, and given that I operate mainly mini or micro scale, that can last me a decade or more, I suppose.

Helium is not produced in Ukraine, as far as I know. The main resources are located in the south of the US. In any case, as you may now, helium is too light to be trapped by Earth’s gravity, so the sole source of it are pockets of gas generated by alpha radioactive decay and trapped into deep caves.

AFAIK it's only for paint strippers destined for the consumer market. Acrylic glues are not affected, so Weld-on #3 is still a good source in the US.
