The scientific and technological achievements appraisal meeting of the "micro-channel continuous flow technology of sulfenamide promoter TBBS series products" jointly developed by Kemai and Changzhou University was held in Tianjin recently. 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, a researcher at the China Chemical Industry Society, and Jiang Zhongyi, a professor at Tianjin University. Wu Zhenyi, chief engineer of the General Hospital, Ma Liangqing, vice president of Beijing Rubber Industry Research Institute, and many other domestic authoritative experts. The experts first visited the R&D installation of the technology and listened carefully to the work report of the technicians. President Li spoke highly of the company's ability to innovate in science and technology.
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. The appraisal committee believes that the results are technologically advanced and technologically innovative, reaching the international advanced level, with remarkable technical and social benefits, high promotion value, and unanimous approval for passing the appraisal.
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 to handle three wastes, and high safety risks. It has achieved clean production and intrinsic safety from the source, with obvious demonstration and driving effects.
