Hi John, Sure John, the process has been around for quite awhile, (along with the chemists, I might add) but the concern is a student research setting. The questions you present are well considered and appreciated.

Hi John,
Sure John, the process has been around for quite awhile, (a long with the chemists, I might add) but the concern is a student research setting.=A0 The questions you present are well considered and appreciated.< br>
Thank you,

=A0
Some questions :
=A0
Does the resea rcher / lab have experience handling highly toxic volatile liquids or gases?
=A0
Does the resea rcher have the proper equipment? This material should always be handled either in a glove box or a Schlenk line (http://en.wikipedia.org/wiki/Schlenk_line);.
=A0
Is the Schlenk line in a well-functioning hood?
=A0
How will any v apors that come out of the inert gas bubbler or vacuum trap or vacuum pump exhaust be destroyed?
=A0
The decomposit ion if Ni(CO)4 to Ni produces CO - how will this be destroyed or vented?
=A0
If the lab is experienced in air-sensitive techniques and has the proper equipment setup, etc., this should not be a problem. If it is someone (usually an engineer or a physical chemist) who s aw this in the literature and is thinking =91it can=92t be that hard=92 - forget it.

One of our researchers would like to use nickel carb onyl to purify nickel.=A0 We call it liquid death.=A0 Does anyone have first hand knowledge working with with this compound?
Thanks
