Versuchsvorschrift

A 5 1 glass reactor with stirrer and thermometer was initially charged with 2.5 l of demineralized water. While stirring, 214.2 g of p-toluenesulfonic acid monohydrate and 2.25 g of iron(III) sulfate heptahydrate were introduced. Once everything had dissolved, 85.8 g of 3,4-ethylenedioxythiophene were added and the mixture was stirred for 30 minutes. Subsequently, 192.9 g of sodium peroxodisulfate were introduced with stirring and the mixture was stirred at room temperature for a further 24 hours. After the reaction had ended, the PEDT/p-toluenesulfonate powder formed was filtered off on a porcelain suction filter, washed with 3 l of demineralized water and finally dried at 100° C. for 6 hours. 89 g of a blue-black PEDT-toluenesulfonate powder were obtained.
