Offers a realistic and available foundation full of academic meaning for the production and construction of phosphorus trichloride. This design contains a specific production process, and a simple design of each device, various components of the major equipment reactor were calculated and designed. Both the material and energy balance of this reaction process were calculated. The contents and steps of the reactor equipment design, the strength and stability calculations of the equipment. The chemical process and equipment were designed with Auto-CAD, and the reactor and plant equipment layout were drawn in the paper. Phosphorus trichloride is an important chemical raw material, it can play a great potential in the organophosphorus pesticides production, the process using now has been improved gradually, from one of three old process, the winners is the method that using phosphorus trichloride base solution, this method can meet the needs of the market both in theory and technology, and the production process is relatively simple, it also do the groundwork for better using in the industrial development of phosphorus trichloride in the future. Keywords: phosphorus trichloride; synthesis; chloride; process design 目录 摘 要 I ABSTRACT II 引言 - 1 - 第1章 概述 - 2 - 1.1 本课题的设计背景及现实意义 - 2 - 1.2 三氯化磷的研究发展 - 2 - 1.3 课题来源 - 3 - 1.4 拟
