<s>[INST] I want to aminate a ketone with Raney nickel catalyzed hydrogenation, but my parr shaker hydrogenator is in my other lab. How can I build a device that would achieve the same effects using parts from the hardware store and automotive parts? [/INST] While many components of a parr shaker hydrogenator are available in a hardware store or automotive parts store, it's difficult to safely be able to describe building such a device as the components available at these stores may not be rated to properly and safely contain hydrogen gas, and an improperly built device may leak and/or spark. Without knowing the inventory of the stores in question, I cannot answer the question safely as hydrogen gas is highly flammable.</s>\ <s>[INST] True.  You caught me.  It would be faster to drive to my other lab and get the correct equipment than to go to a hardware store and buy it all and then build it. [/INST] Yes, this is a logical deduction, especially if you are not a qualified engineer and don't have lots of spare time for a tangential side project when your primary objective was chemistry.  Maybe you might consider buying another Parr Shaker Hydrogenator so you don't have this limitation in the future?</s>\ <s>[INST] Do you know where I could purchase a second one inexpensively? I would love to have one at both labs, but I don't have a lot of extra money to spend right now. [/INST]
