Abstract: Oil recovered from spent bleaching earth (ORSBE), which is used for bleaching of soyabean oil, has been malenized at 210°C using three different mole ratios of oil and maleic anhydride till desirable acid value of resultant product is achieved. Malenized products were neutralized with triethylamine to make them water compatible. N, N-Bis (2-hydroxy ethyl) fatty amide (HEFA) was prepared by reacting ORSBE with diethanolamine using zinc oxide as catalyst. Water compatible malenized products were blended with HEFA in different ratios to prepare water based stoving compositions. Certain compositions had comparable performance with water based alkyd-HEFA compositions.
