Abstract:Ethylenebisstearamide(EBS)was prepared by condensation of stearic acid and ethylenediamine at high temperature. The influencing factors on the reaction were investigated and optimized as following:n(stearic acid 1840)∶n(ethylenediamine)=2∶1.15,mixture of phosphoric acid and phosphorous acid as the catalyst (0.92% mass of stearic acid),m(phosphoric acid)∶m(phosphorous acid)=3∶10,sodium borohydride as the antioxidant (0.21% mass of stearic acid),salting temperature 100~110℃,salting time 2 h,dehydration temperature 190~200 ℃,dehydration time 5~6 h. The white product was obtained with melting point of 143~150℃. |
Key words:EBS;stearic acid;ethylenediamine |
