Yield:-
Reaction Conditions:
in hexane;
Steps:
3 Synthesis of Potassium Tert-amylate (PTA) in Hexane at 60° C. in the Presence of a Stoichiometric Quantity of Isoprene
25.3 g (648 mmol) of purified potassium crusts (Merck) were melted in 305 g hexane in a 0.5-1 twice clad reactor with a precision glass stirrer, reflux condenser and drip funnel, and then a mixture of 57.1 g (648 mmol) tert-amyl alcohol and 22.1 g (324 mmol) isoprene was added thereto at approximately 60° C. within 100 minutes. During the addition process, the reaction mixture became slightly cloudy, although was easy to stir. At the end of the addition, refluxing was effected for 10 minutes, with a clear, slightly yellowish solution being formed. The filtered solution was concentrated by evaporation in a rotation evaporator under vacuum. 74.8 g (92%) of a colourless powder was obtained that had the expected composition for PTA.
