摘要
在自制催化剂作用下,对鱼油进行空气氧化,再对氧化产物进行亚硫酸化,这种两步法制备氧化亚硫酸化鱼油工艺是对传统氧化亚硫酸化工艺的改进,该工艺操作简单、生产周期短。最佳的氧化工艺条件为:氧化温度65~70℃,催化剂用量2%,氧化反应时间5~6h;亚硫酸化工艺条件为:反应温度70~75℃,亚硫酸盐用量8%~12%,时间2~3h。应用试验表明,用该方法制备的氧化亚硫酸化鱼油是一种性能优良的皮革加脂剂。
The refined fish oil was catalyzed and oxidized with air, then sulphited. This two - step process to produce oxidized - sulphited fish oil is an improvement of the traditional one - step process. The merits of this process are: more convenient operation and shorter producing period. The optimized conditions for oxidation are: temperature, 65~70℃; amount of catalyst, 2%; reaction time, 5~6h; and those for sulphitation are: temperature, 70~75℃; amount of sulphite, 8~12%; reaction time, 2~3h. It is shown from application experiments that the oxidized - sulphited fish oil fatliquoring agent produced using this process has remarkable properties.
