Acetyl chloride → HCID 54351123, compound

Participants

Reaction Steps

The same equipment and procedure as in Example 1 was employed. The reaction flask was charged with 100 ml ethylene dichloride and 85 g acetyl chloride (1.1 mole). The addition of 270 g (1.0 mole) tris (β-chloroethyl) phosphite was commenced dropwise and continued for one hour during which there was a slow exotherm to 35° C. After addition of the triphosphite the reaction continued with a self-maintained exotherm at about 40° C. for three hours and then a slow return to ambient temperature while stirring overnight. The pink acetyl bis(β-chloroethyl) phosphite was isolated by rotary evaporatory at 50° C. and 15 torr. The yield was 261 g; acid number 2; purity by infrared analysis was about 75%.
