Sulfuric Acid → 2-[Ethyl(phenyl)amino]ethyl hydrogen sulfate

Participants

Reaction Steps

In 1.1, 16.5 grams (g) (0.10 mol) of 2-(N-ethylanilino)ethanol were added to 25.0 milliliters (ml) of concentrated sulfuric acid at a temperature of 35 to 40 degrees Celsius (° C.). The reaction proceeded slightly exothermically and was held within the specified temperature range by cooling with iced water. The mixture was stirred for an additional 2 hours. On completion of the reaction, the mixture was poured onto ice and made up to 250 ml by adding water. The result was a transparent yellow solution, which was used in the next stage with no further processing.
