本文以石蜡对研究对象,对石蜡的催化氧化改性工艺条件进行了研究,考察了空气流量,催化剂用量,反应温度和反应时间对石蜡氧化过程的影响以及反映条件对氧化石蜡性质的影响。并确定了最佳的反应条件催化剂负载量为15%,催化剂用量问0.5g,温度为150℃,空气流量为0.6,反应时间为4小时。可得到色泽浅、气味轻、酸值较高的氧化石蜡产品。
关键词:石蜡,氧化,氧化石蜡,酸值
很明显,楼上的是用翻译软件翻译的
鄙视~~
楼主,如果没有他、满意答案,可以选我吗?many thks!
两分先拿走~~~
Wax is an important industrial raw materials, widely used in food, medicine, household chemicals, leather, textile and other industries and agriculture. Over the years, various sectors of China's use of the special wax is to reconcile some wax, with the industrial structural adjustment and industrial progress. Reconcile the wax has been unable to meet demand. For example, ink used in the beeswax used as a cheap alternative paraffin, oil-film-formed granular skin, because paraffin is not soluble ink base material. In addition, the paraffin emulsion was also difficult, when needed a lot emulsion emulsifier, emulsifying wax so that the application be limited. Paraffin will be modified through the introduction of - OH, COOH, CO, COOR, and other groups. Can change its physical and chemical properties. Of the methods used for chemical modification of paraffin, wax can achieve the high value-
