Conditions

Temperature
80 °C

Procedure

85% phosphoric acid (1.0 mole) was added to a solution of octadecylamine (1.0 mole) in THF until the pH reached 5. The white precipitate was filtered under reduced pressure with a water aspirator and then washed with water. The white precipitate was dispersed in water at 10% solids. The white dispersion was warmed to a cloudy dispersion at 80° C. before coating.

Workup

  1. filtrationThe white precipitate was filtered under reduced pressure with a water aspirator
