The production methods, techuological and economic indexes of MTBE are introduced. Several problems such as reaction conditions, types of reactor, azeotropism etc. in the MTBF process are also discussed. It is feasible and economic the prodnce MTBE employing corresponding processes with steamcracked raffinate and cat-cracked C_4 as feedstocks. New processes should be developed in order to widen the sources of feedstocks. It is considered that the key to the reduction of the MTBE synthesis cost lies in the cutting down of the feedstock consumption. Utilizing the bucket reactor and pressure distillation in commercial plants have advantages.

介绍了MTBE的制取方法,技术经济指标,并对MTBE工艺中的反应条件、反应器型式及共沸等问题进行了初步讨论。利用蒸汽裂解抽余油及催化裂化提供的C_4为原料,采用相应的流程制取MTBE是可行的,经济的。为扩大原料来源,应开发新的技术路线。认为,降低MTBE合成工业成本的关键是降低原料消耗。以筒式反应器作为大工业生产装置中的反应器并采用加压精馏具有优越性。

This article describes a new technique of preparing cyclohexanol and cyclohexanone from benzene: firstly, benzene is converted into cyclohexene or cyclohexylbenzene, from which cyclohexanol and cyclohexanone are prepared. Attention is being paid incresiagly to this technique due to its advantages. The process of hydration of cyclohexene to prepare cyclohexanol was industrialized in Japan in 1990.

介绍了经苯制环已醇、环已酮的新技术路线:苯转化为环已烯或环已基苯,再由此制备环弓醇及环已酮。由苯经环已烯制环已醇及环已酮,由于工艺上的优点,日益引起人们的重视。1990年日本实现了环已烯水合制环已醇的工业化。

The key industrial steps in the new polyamide production processes abroad in recent years, such as partial hydrogenation of benzene to cyclohexene, hydration of cyclohexene to cyclohexanol and direct oxidation of cyclohexene to cyclohexanone, are reviewed. The trends of direct oxidation of cyclohexanone to hexanolactam and developments of different routes in preparation of feed stocks of nylon-66 are also described.

评述了近年来国外在聚酰胺生产中出观的新技术路线中的关键步骤——苯部分加氢生成环己烯、环己烯水合生成环己醇及环己烯一步氧化直接生成环己酮。简介了环己酮直接氧化制己内酰胺的发展趋势及尼龙-66生产原料路线的开发动向。
