摘要
在光催化下对经甲醇醇解改性的菜油进行空气常温氧化,然后对氧化产物进行亚硫酸化。试验最佳的工艺技术参数为:氧化反应过程中,助剂R1的用量为油脂质量的1.5%,光波为长波(365nm),常温氧化反应4~6h;亚硫酸化反应温度70~75℃,亚硫酸钠用量10%~12%,时间2~3h。应用试验表明,该方法制备的氧化亚硫酸化菜油具有良好的加脂性能。
Catalyzed with ultra violet light ( UV), the alcoholysed rapeseed oil was oxidized with air at room temperature, and then sulphited. The optimized conditions for oxidation are: room temperature, amount of catalyst during oxidation is 1.5%, wave length of light is long wave(365nm) and reaction time is 4 - 6h ; and those for sulphitation are : temperature is 70 - 75℃, amount of sulphite is 10% - 12%, reaction time is 2 -3h. The application experiments show that the oxidized - sulphited rapeseed oil produced with this process has good properties.
