Participants

Conditions

Temperature: 90 °C

Procedure

A solution of 313.5 g (1.98 mol) calcium acetate in 1000 ml water was added to a solution of 570 g (1.98 mol) dodecenyl succinic anhydride in 1000 ml isopropanol. The mixture was then heated to 90° C., left at that temperature for 1.5 h and then concentrated in a water jet vacuum. The residue was dried in vacuo in a drying cabinet at 100° C. 680 g of the calcium soap were obtained in the form of a colorless powder.
