Reaction Steps

66.9 g of 2,4,6-tri-t-butylphenol was dissolved or dispersed into 213.5 g of tri-n-propyl amin. To this solution was added 13.5 of sodium methoxide. The mixture was heated in flask until reflux occurred at about 150° C. When the reflux temperature dropped below 150° C., distillate was condensed and removed from the reaction mixture until the vapor temperature in the flask rose above 150° C. then the mixture was again refluxed. When the vapor temperature dropped below 150° C., distillate was condensed and removed from the reaction mixture until the vapor temperature rose above 150° C. This alternate process of reflux and condensation was repeated until 8.0 g of methyl alcohol, CH3OH had been distilled Away from the reaction mixture. Approximately 112 g of tri-n-propyl amine was stripped from the reaction mixture leaving about 71 g of sodium 2,4,6-tri-t-butyl phenolate in about 100 g of tri-n-propyl amine as a 40 weight percent slurry of the phenolate salt in the amine solvent.
