Versuchsvorschrift

A solution of dehydroabietylamine (60%, 100 g, 0.21 mol) in toluene (170 mL) was treated with a second solution of glacial acetic acid (24 mL) in toluene (55 mL) at room temperature. The mixture was stored at room temperature overnight. The crystalline salt was collected by filtration, washed with cold toluene and recrystallized from boiling toluene (152 mL). The crystals were collected by filtration, washed with n-pentane and air-dried to give dehydroabietylamine acetate (47 g, 78%) as a white crystalline solid.
