目前国际最先进的碳五烯醇合成技术路线--以异丁烯和甲醛为原料的Prins缩合反应,已被德纳国际企业有限公司研发中心成功掌握。德纳公司副总裁、项目带头人杨建国博士表示,碳五烯醇合成技术的突破,有助于打破国内聚羧酸减水剂产业面临的原料瓶颈。同时该工艺属原子经济性反应,符合绿 At present, the international advanced carbon pentalene synthesis technology route - Prins condensation reaction with isobutylene and formaldehyde as raw materials has been successfully mastered by Dana International Enterprise Co., Ltd. R & D Center. Dr. Dennis Yang, Vice President and Project Leader of Dana Corporation, said that the breakthrough of carbon pentalene synthesis technology will help to break the bottleneck of raw materials for the domestic polycarboxylate superplasticizer industry. At the same time the process is atomic economic response, in line with the green
