Conditions

Temperature: 85 °C

Procedure

In a 21-4-necked glass reaction flask, supplied with dispersion wheel (circumference of 8 cm), reflux cooler, nitrogen supply pipe, thermometer and dosage device, 91.9 gr. of styrene =0.88 moles (purity >99%, stabilized with 0.005% 4-tert-butylcatechol), 79.2 gr of maleic acid anhydride =0.808 moles (purity >99%) and 215.2 gr. distilled stearyl amine =0.8 mole (Arneen 18 D , the Akzo Nobel company) are heated while stirring to a temperature of 85° C., until a clear solution of the reaction product, maleic acid monostearyl amide in styrene is formed.
