摘要(Abstract)：

己二腈是一种重要的化工中间体，作为生产尼龙66的原料之一，其技术长期被国外垄断。丁二烯氰化法作为世界最先进的己二腈生产工艺，需要以高纯氢氰酸为原料，而氢氰酸是一种剧毒化学品，不能进行储运，因此研究高纯氢氰酸的就地生产是十分重要的。自主开发的甲醇氨氧化制取氢氰酸项目已完成实验室阶段开发，但遇到吸收效率低、氢氰酸易聚合的问题。巧妙运用了TRIZ理论提出整改方案，对甲醇氨氧化生产氢氰酸工艺进行改进，成功地解决了两大难题，为后续工业化开发提供重要基础。
Adiponitrile is an important chemical intermediate. As one of the raw materials for the production of nylon 66, its technology has been monopolized abroad for a long time. As the world's most advanced adiponitrile production process, butadiene cyanidation requires high purity hydrocyanic acid as raw material,and hydrocyanic acid is a highly toxic chemical which can't be stored and transported, so it is very important to study the local production of high purity hydrocyanic acid. The self-developed project of ammonia oxidation of methanol to produce hydrocyanic acid has been developed in the laboratory stage, but it has encountered the problems of low absorption efficiency and easy polymerization of hydrocyanic acid. With the clever use of TRIZ theory, the rectification plan was put forward to improve the process of ammonia oxidation of methanol to produce hydrocyanic acid, which successfully solved the two major problems and provided an important foundation for the subsequent industrial development.
