Sodium Bicarbonate → 2-Methoxy-4-(phenylamino)-benzenediazonium hexadecyl sulfate

Participants

Reaction Steps

3.25 g of 2-methoxy-4-(phenylamino)-benzenediazonium bisulfate (Diverstec, Fort Collins, Colo.) in 50 ml of water was neutralized with 0.8 g of NaHCO3 in 25 ml water, and marked the container with A. 3.45 g of sodium hexadecyl sulfate (TCI America, Portland, Oreg.) was dissolved in 150 ml of water AT 50° C., and marked the container with B. While stirring, solution A was slowly added into solution B and the precipitate was formed after mixing was completed. The reaction mixture was stored in dark at 0-5° C. for 12 hours. The solid was collected by filtration and then dried by vacuum. The yield was 5.4 g.
