Online Physical Properties of Compunds

Can some point me in the direction of online sites etc that have databases of physical data about any product.

Also MSDS (i found some but they are not very useful)

Looking for something like CRC handbook and Perry tables all rolled into one search system with MSDS attached

Good luck. Back in 1998 I tried searching for a similar source to populate some data tables we were putting together for a new plant. We ended up using Perry's, the CRC, and a couple of college textbooks.

You can try getting abstracts from the internet on individual materials, but back in 98 they made you pay dearly for the info. SteamJetPE
Ejectors, LRVPs, Hybrids
Troubleshooting, startup, design

hi

the physical properties side on the net is bad but the CDC (NIOSH - national institute...occupational safety and health or something like that) in the USA has some info which is usefuly for MSDS.

check it out at

http://www.cdc.gov

then use the search engine

eg of the info supplied

Making a physical handbook is _a lot_ of work, and im not surpriced its not there. Many vedors do however supply information re. the compounds that they sell.

So try to search for something specific on e.g. google and look out for know vendor - or go directly to a vendor site and search here.

Best Regards

Morten

 

you might try chemfinder.com This has some information for you too. I do agree with Morten. The company that produces the chemical is the best source and I believe DOT requires an MSDS for a chemical shipment.

Good luck
