With sodium ethylate in ethyl acetate solution it forms the sodium derivative of benzoyl acetone, from which benzoyl acetone, C6H5.CO.CH2.CO.CH3, can be obtained by acidification with acetic acid.
It combines directly with acetone and with various amines.
With a dissertation on acetone in 1858.
A historic example is that of the condensation of three molecules of acetone, CH 3 CO CH 3, in the presence of sulphuric acid, to s-trimethylbenzene or mesitylene, C 6 H 3 (CH 3) 3, first observed in 1837 by R.
Somewhat similar condensations are: of geranial or citral, (CH 3) 2 CH CH 2 CH :CH C(CH 3) :CH CHO, to p-isopropylmethylbenzene or cymene; of the condensation product of methylethylacrolein and acetone, CH3 CH2 CH:C(CH3) CH:CH CO CH3, to [1.3.
