【Ten Years of Great Progress in Chemical Technology】The key technologies for producing high-purity 1,4-butanediol via the alkyne-aldehyde method from 2014 to 2023 have passed evaluation

Thread Content

Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with you here; we welcome everyone to join in the forum discussions. Be careful with fire as the heat increases in July. ----------------------------------------------On July 6, 2023, the scientific and technological project focused on key areas by the Binguu Regiment, undertaken by Tianye Group’s Tianzhi Chenye Chemical Co., Ltd., namely “Research and Development and Application of Key Technologies for Producing High-Purity 1,4-Butanediol via the Alkyne-Aldehyde Method,” was successfully approved after evaluation. It is reported that this project builds on Tianzhi Chenye’s independently developed dry-process acetylene production technology and calcium carbide furnace gas purification and hydrogen production technology. By focusing on issues such as the sulfur content in the acetylene gas used as raw material for 1,4-butanediol production, the lifespan of hydrogenation catalysts, and the refinement of 1,4-butanediol products, the company carried out scientific research efforts that ultimately resolved the technical barriers to further improving the quality of 1,4-butanediol products, thereby laying the foundation for these products to enter high-end markets in the future. A total of **8 patents** have been applied for in relation to the project’s technical achievements, including 2 invention patents and 6 utility model patents. 6 authorized utility model patents were obtained, and 2 enterprise standards were established. The successful implementation of this project generates annual economic benefits of over 8 million yuan, and enables the products produced by the alkyne-aldehyde process using non-petroleum routes to enter high-end application fields. It has played a positive role in guiding technological innovation within the same industry, and it is also crucial for addressing the overcapacity in 1,4-butanediol production and for exploring foreign markets. At the acceptance meeting, the expert panel concluded that the project had met all the established evaluation criteria and achieved good social and economic benefits, and unanimously agreed to approve its acceptance. The project acceptance expert panel gave high praise to the company’s technical research efforts and the quality of project completion throughout the project implementation process. A responsible official from the company said that they will continue to lead their team in increasing investment in research and development, making greater efforts in technological innovation and quality improvement, so as to further advance technological progress and innovation capabilities within the industry.
