Procedure

A carbon black with a CTAB surface area of 350 m2 /g and a DBPA of 120 ml/100 g was used. A suspension of 50 g of this carbon black was prepared by stirring it into 450 g of water that contained a few drops of isopropanol. A solution of 5.12 g of NaNO2 in 10 g of cold water was slowly added to a dispersion of 17.91 g of 4-tetradecylaniline, 11.88 g of concentrated nitric acid and 20 ml of acetone in 100 g of water that was cooled in an ice bath. 4-Tetradecylbenzenediazonium nitrate was formed. After 15 minutes of stirring, the mixture was added to the stirring carbon black suspension. Bubbles were released. After 30 minutes, the product was collected by filtration, washed with water and tetrahydrofuran (THF) and dried in an oven at 125° C. The carbon black product had attached p-C6H4C14H29 groups.
