A simple method for incorporating amine groups in hydrogenated castor oil (HCO) to produce wax for beeswax or carnauba wax substitution in packaging and coating was developed. From the conversion rate of the products, HCO was reacted with ethanolamine at 150°C for 5 h, and the molar ratio of HCO and ethanolamine was 1:4. The hardness of the final product was seven times higher than that of beeswax, the cohesiveness of the final product was 1.3 times higher than that of beeswax and approximately one half of that of carnauba wax, and the melting point of the final product is 98°C. The Fourier transform Infrared spectroscopy showed that the amide groups were incorporated to form the amide products. In coating application, the results showed that the force of the final product coating cardboard was higher than that of beeswax and paraffin wax and less than that of carnauba wax. After 24 h soaking, the compression forces were decreased. HCO fatty acid wax can be an alternative wax for carnauba wax and beeswax in coating applications.
开发了一种在氢化蓖麻油（HCO）中引入胺基以生产用于包装和涂层中替代蜂蜡或巴西棕榈蜡的蜡的简单方法。根据产物的转化率，HCO在150℃下与乙醇胺反应5小时，HCO与乙醇胺的摩尔比为1:4。最终产物的硬度比蜂蜡高7倍，内聚性比蜂蜡高1.3倍，约为巴西棕榈蜡的一半，最终产物的熔点为98℃。傅里叶变换红外光谱表明酰胺基团被引入形成了酰胺产物。在涂层应用中，结果表明最终产物涂覆纸板的力高于蜂蜡和石蜡，低于巴西棕榈蜡。浸泡24小时后，压缩力降低。HCO脂肪酸蜡可作为涂层应用中巴西棕榈蜡和蜂蜡的替代蜡。
