Stearoyl chloride → HCID 20249612, compound

Participants

Reaction Steps

16.4 g (0.1 mol) of 4-hydroxymethyl-1-phospha-2,6,7-trioxabicyclo[2,2,2]octane are dissolved in 150 ml of toluene by warming. 30.2 g (0.1 mol) of stearic acid chloride, followed by 10.1 g (0.1 mol) of triethylamine, are added dropwise at room temperature. After the slight evolution of heat has died away, the mixture is stirred for 10 hours under nitrogen at room temperature and the precipitated triethylamine hydrochloride is then filtered off. The filtrate is evaporated with exclusion of moisture, a yellowish oil remaining, which crystallises on being triturated with methanol. After filtering off under suction and drying, stearic acid 1-phospha-2,6,7-trioxabicyclo[2,2,2]oct-4-yl-methyl ester (Stabiliser No. 9), melting point 49°C, is obtained.
