(1) Proto-type systemProto-type system for computer-aided development of azeotropic distilllation systems has been made on a personal computer.(2) Database and quasi-databaseAn azeotropic database with 1,706 data on pure materials, 18,279 data on binary azotropes and 921 data on ternary azeotropes has been made and quasi-databases have been made for estimating lacked data on pure materials, binary azeotropes and ternary azeotropes.(3) Examination of performance of the systemIn order to examine the performance of the system, selection of the In order to examine the performance of the system, selection of the entrainers for azeotropic distilllation utilizing heterogeneous binary azeotropes has been carried out and the obtained entrainers have been compared with those of existing processes.(4) Extention to heterogeneous ternary azeotropesThe system has been improved to be able to search for the entrainers for azeotropic distilllation processes utilizing heterogeneous ternary azeotropes.

(1)共沸精馏系统的计算机辅助开发原型系统已在个人计算机上完成。(2)数据库和准数据库建立了共沸物数据库，其中纯物质数据1,706个，二元共沸物数据18,279个，三元共沸物数据921个，并建立了准数据库，用于估算纯物质、二元共沸物和三元共沸物的数据。(3)为了考察系统的性能，对利用非均相二元共沸物进行共沸精馏的精馏塔进行了选择，并将所得精馏塔与现有工艺进行了比较。(4)对该系统进行了改进，使其能够搜索利用非均相三元共沸物的共沸精馏过程的共沸剂。
