On June 26, the scientific and technological achievements of the “micro-channel continuous flow technology of sulfenamide promoter TBBS series products” jointly developed by Kemai and Changzhou University passed the appraisal of the expert group of China Petroleum and Chemical Industry Federation. The appraisal committee believes that the results are technologically advanced, technologically innovative, technically and socially significant, reaching the international advanced level and having a high promotion value.
The experts first visited the R&D installation of the technology and listened carefully to the work report of the technicians. At the review meeting, the participating experts listened to the technical research report of the project, and reviewed the technical data such as the scientific research report, test report and economic benefit analysis. It believed that the project initiated the microchannel reaction of the sulfonamide accelerator TBBS and other products. The technology has built a thousand-ton-class device, which is efficient, clean and safe compared with the kettle-type and batch processes.
By designing a unique microchannel reactor, the reaction time was shortened from about 1.5 hours to 3 seconds, and the liquid holding capacity was as low as 0.1‰ of the traditional process. The continuous and automation level was significantly improved. The project solves many problems such as low yield of traditional process, difficult treatment of “three wastes”, and high safety risks. It achieves clean production and intrinsic safety from the source, and has obvious demonstration and driving effects.
The appraisal meeting was organized by the China Petroleum and Chemical Industry Federation. The experts who participated in the review were Li Yongwu, former president of the China Petroleum and Chemical Industry Federation, Xu Chunhua, researcher of the China Chemical Industry Society, Jiang Zhongyi, professor of Tianjin University, and Sinochem Chemical Science and Technology Research. Wu Zhenyi, chief engineer of the General Hospital, Ma Liangqing, vice president of Beijing Rubber Industry Research Institute, and many other domestic authoritative experts.
