Yes, there is a question of damage as well as how do you now clean the meteorite of the kerosene?

Perhaps someone with more chemistry knowledge can assess how bad any of the following might be to meteorites: 1. methanol (as Rosie pointed out) -- shouldn't be too bad, given that it's just wood alcohol. 2. ethyl acetate 3. kerosene 4. gasoline 5. benzene 6. methyl isobutyl ketone 7. acetone 8. diethyl phthalate 9. crotonaldehyde 10. brucine sulfate There are others, but these are the most common ones. --Rob _________________________________________________________________ Store more e-mails with MSN Hotmail Extra Storage – 4 plans to choose from! http://click.atdmt.com/AVE/go/onm00200362ave/direct/01/ Received on Sat 13 Mar 2004 01:41:13 AM PST |
