Understood. At this point, merely being up late at night is enough to fog my mind more than drugs and alcohol ever did when I was a teen.
From the start of organic chemistry classes, students are told of the dangers of peroxides in ethers, notably THF, DIPE, and diethyl ether. It's natural for all chemists even PhD's to think that all ethers form peroxides, though I'd expect a PhD to be cautious in saying specifically that DME is included.
A quote on peroxidizability, right after trashing safety officers
http://www.bnl.gov/esh/cms/PDF/peroxides.pdf
The auto-peroxidation potential of a compound is greatly influenced by adjacent and nearby functional groups. These relationships were first reported by Jackson et al (6) and subsequently refined by other authors (3, 15, 16, 22). Peroxide-forming compounds invariably contain an autooxidizable hydrogen atom that is activated by adjacent structural components and/or actinic radiation (not necessarily continuous). These compounds react with atmospheric oxygen under ambient conditions to initially form a hydroperoxide (3). Initially, the autocatalytic reaction proceeds very slowly, then the rate gradually increases to a maximum velocity.
Activated hydrogen atoms are often on a:
v Methylene group adjacent to an ethereal oxygen atom (-O-CH2-, e.g. diethyl ether, THF, dioxane, diglyme).
v Methylene group adjacent to a vinyl group or benzene ring (C=C-CH2- or Ph-CH2-, e.g. allyl or benzyl compounds).
v CH group adjacent to two ethereal oxygen atoms (-O-CH-O-, e.g. acetals or methylenedioxy compounds).
v CH group adjacent to two methylene groups (-CH2-CH-CH2-, e.g. isopropyl compounds and decahydronaphthalenes).
v CH group between a benzene ring and a methylene group (-CH2-CH-Ph, e.g. cumene and tetrahydronaphthalenes).
v A vinyl group (-C=CH2, e.g. vinyl compounds, dienes, styrenes or other monomers)
We are not chemists, so that is verbal diarrhea. We read MSDS, which states it is DANGEROUS. Will you accept liability for your recommendation? Or are you like Dr Z, who will skip country when something goes wrong.
Couldn't you be happy with flow through market, where there is no problem????????????
NRN
YOUR ARTICLE PROVES MY POINT, if read!!!!!!!!!!!!!!!!!!!!!!!!!!
Do not want to be rude, but can not see why you would recommend something so sketchy. Their premier product was poison (known cancer causer), and not sold anymore.
Dupont said it causes peroxides!!!! You claim to know more than them?????????????????
It will be safe for one year, in sealed containers, not exposed to water, air, heat , distillation, UV light.
My only vested interest is helping the great people of ICMAG, which have helped my so much, out of the kindness of their hearts. The people I know here, are better than the friends I have in real life.
