In a post by Aminator (?) I printed out some time ago it is stated that when performing an Al/Hg reduction:
If 40% methylamine in water is used (instead of the MA salt) the following substitutions can be made. In sequence add 128g aqueous methylamine, 302 ml isopropyl alcohol (100%), a suspension of 84g NaCl (table salt) in 42 ml 25% NaOH that has been diluted to 235 ml with water, 89g (0.5 moles) of piperonylacetone, and finally 588ml isopropyl alcohol(100%).
Can someone tell me why the salt is added? Don't understand why it should be added . Well, never did this type of reaction so maybe there is a good reason....
I'm more curious about the things I dream than about things I see when awake!
