费-托蜡接枝马来酸酐的研究

Fischer-Tropsch Wax Graft With MAH

以过氧化苯甲酰(BPO)为引发剂,采用熔融接枝的方法,将马来酸酐(MAH)接枝到H-1型费-托蜡上,使费-托蜡的硬度等性质得到改善。实验结果表明,反应时间20 min,反应温度140℃,马来酸酐质量5.0 g,引发剂质量4.0 g时,接枝率达到1.53%,所得产品的针入度达到1.6(0.1 mm)。经红外光谱分析,表明马来酸酐确已接枝到费-托蜡上。

In the presence of the initiator benzoyl peroxide （BPO）, maleic anhydride （MAH） was grafted onto a kind of H- I type fischer-tropsch wax by melt grafting process to improve the hardness and other indicators of Fischer-Tropsch wax. The experimental results show that, when the reaction lasted for 20 min at the reaction temperature of 140 ℃, the amount of maleie anhydride （MAH）was 5.0 g and the amount of initiator （BPO）was 4.0 g, the grafting rate reached 1.53% while the product＇s penetration degree was 1. 6 （0. 1 mm）. From the infrared spectroscopy （IR）, we can see that MAH had been successfully grafted to the fischer tropseh wax.
