at 140 u00b0 c the heat of reaction as well as the excess energy of the dispersing apparatus were drawn off at the reflux condenser through the solvent mixture refluxing at 130 u00b0 c immediately after the end of the alcohol addition the reaction mixture was released from pressure and drawn off there was obtained a yellow colored clear solution of sodium tert butylate the reaction was complete in the previously described reactor there were heated 3 5 kg of the solvent mixture according to example 1 to 150 u00b0 c whereupon the pressure adjusted itself to 6 6 5 atmospheres absolute then the dispersing apparatus was switched on and there were fed in uninterruptedly with a pump exactly 92 grams 4 0 mols of liquid sodium metal then there were fed in within 15 minutes 352 5 grams 4 0 mols of dry tert amyl alcohol the reaction was then controlled as in example 1 one minute after the end of the alcohol addition the reaction mixtures were relieved of pressure and drawn off there was obtained a yellow colored clear solution of sodium tert amylate the reaction was complete 3 5 kg of a solvent mixture of 90 cyclohexane and 10 toluene and 296 5 grams 4 0 mols of tert butanol were heated to 150 u00b0 c in the above described reactor then the dispersing apparatus was switched.
