Database
| Quote: | | Oekopro is the first interactive chemical database on the Internet. Do you want to know which substances are contained in colors and varnishes, in
printed products, batteries, tires or photo developers? Are you interested in chemical/physical data or toxicological or ecological facts? Do you want
to know, why a substance is used in a product and wether there are alternatives which are more agreeable for the workplace or the environment? Or do
you want to view the structural formula in an animated, three dimensional presentation (requires the Chemscape Chime Plugin) or print out datasheets
with all these informations? All this - and more, is provided by Oekopro. |
Only 5 substances per user and day, registration (e-mail) required. Not bad for free.....
eh, the link of course:

spektrum & oxide
are in english and oekopro has also an english interface - available by clicking on "english"!
My tip is the oxide database - everything available from pottery supplies and heaps of information I never have seen anywhere else.
Have a look!

Did take a look Oeken looked pretty interesting but was in german, i read most of the oxide site, but the many of the info are only the color they
give in glass blowing... pretty interesting though

this is site is free and i use it regularly, it's a large collection of safety data pages. It's from the university of akron it stopped me
from playing potassium permangnate which had a health hazard of 3.

misleading MSDS information
Others have said this better, but it appears to need saying again:
The MSDS generally errs on the side of extreme caution. It errs so much in that direction as to be almost useless at times. For example, according to
the database you linked to, potassium permanganate and sodium cyanide pose the same health hazard (they both get a 3). Curiously, potassium cyanide,
which is essentially identical to sodium cyanide when it comes to hazards, earns a 4 for health. Is this because it is more prominently featured in
murder mysteries?
Even more puzzling, both cyanides are assigned a reactivity rating of zero, even though the text explicitly mentions that they will react with acids
and can react with oxidizers. The text on KCN contains this gem of a sentence: "Reacts with strong oxidizers such as nitrates and chlorates,
nitrogen trichloride; perchloryl fluoride; sodium nitrate; acids; alkaloids; chloral hydrate; iodine." Alkaloids are strong oxidizers?!
Other fun stuff:
"Mercuric chloride may explode with friction or application of heat."
Thionyl chloride, acetic acid, sodium nitrite, and strychnine sulfate are all level 3 health hazards.
Their MSDS for <A HREF="http://www.aflatoxin.info/health.asp">aflatoxin</A> gives it a health rating of 2, putting it on equal
footing with citric acid.
So it appears that this MSDS collection makes no attempt at internal consistency and underestimates threats as well as overestimating them. I'd
bookmark it under "humor."

By my knowledge is every accident related to a chemical to be reported and will go into the MSDS - for assurance reasons of public institutions. So if
a student breaks his toes because a bottle of H2O fell on them during handling another compound and this happens by coincidence twice a year, the
compound will be rated dangerous in connection to water automatically. Just to be sure.
I see it this way: It´s like Marihuana, the campaigns telling grass is a hard and dangerous drug render every reasonable advice related to cocain and
else worthless.
Thats overprotectiveness or "teacherism", the goodwill terror regime of the social workers - sweden was long time leading in this.

Heterocompounds
X-PLOR Topology and Parameter Library for Hetero Compounds
from Sweden!
but english!
thats molecule LEGO! A construction set for .pdb and else 3d files, this makes it very easy to build correct molecules. Handy! Together with the VIEWER lite which is free and converts virtually all chemical formats.
