Reaction Conditions

Reaction Steps

A 4.1 g (20 mmol) quantity of mono(2-ethylhexyl)maleate manufactured by Aldrich Co. was slowly added dropwise to 4.1 g (20 mmol) of phosphorus pentachloride while maintaining a temperature not greater than 30° C. When the dropwise addition had been completed, stirring was conducted for 1 hr at room temperature. Subsequently, the mixture was heated to 60° C., the pressure was reduced with an aspirator, and the phosphorus oxychloride was distilled off, yielding 4.5 g (yield of 92 percent) of maleic acid mono(2-ethylhexyl)ester monochloride in the form of a tea-colored oily product.
