    • A continuous alkoxylation process for the production of polyether polyols is disclosed. The process comprises the use of a plurality of reaction modules each having an outer tube and an inner tube with annular chamber between them. A spiral reaction tube is spaced from the inner tube and winds around the inner tube within the annular chamber. The spiral reaction tube includes an inlet and an outlet, each of which extend through said outer tube. A heat exchange medium flows through the annular chamber and controls the reaction temperature in the spiral reaction tube. The process comprises continuously forming an initial reaction mixture of at least one alkylene oxide and an initiator having at least one reactive hydrogen which is reactive to the alkylene oxide. Continuously flowing the initial reaction mixture through a first spiral reaction tube having an internal diameter and a spiral diameter that promote a pseudo-turbulent flow of the initial reaction mixture through the first spiral reaction tube to form a reaction product. Then flowing the reaction product into a second spiral reaction tube and adding a catalyst and an alkylene oxide to the reaction product, the second spiral reaction tube having an internal diameter and a spiral diameter that promote a pseudo-turbulent flow of the reaction product, the catalyst and the alkylene oxide in the second spiral reaction tube.
    • 公开了用于生产聚醚多元醇的连续烷氧基化方法。 该方法包括使用多个反应模块,每个反应模块具有外管和在它们之间具有环形室的内管。 螺旋反应管与内管间隔开并围绕环形室内的内管缠绕。 螺旋反应管包括入口和出口,每个入口和出口延伸穿过所述外管。 热交换介质流过环形室,并控制螺旋反应管中的反应温度。 该方法包括连续地形成至少一种环氧烷和具有至少一个与环氧烷反应的反应性氢的引发剂的初始反应混合物。 将初始反应混合物连续流过具有内径和螺旋直径的第一螺旋反应管,该第一螺旋反应管促使初始反应混合物通过第一螺旋反应管的假湍流,形成反应产物。 然后将反应产物流入第二螺旋反应管并向反应产物中加入催化剂和烯化氧,第二螺旋反应管具有促进反应产物的假湍流的内径和螺旋直径, 催化剂和第二螺旋反应管中的环氧烷。

    • A continuous process for the formation of sucrose based polyols is disclosed. The process comprises the steps of continuously forming an aqueous sucrose solution which is continuously combined with a catalyst and an alkylene oxide and flowed through a first spiral reaction tube. The alkylene oxide substantially completely reacting with the aqueous sucrose solution occurs to form a pre-polymer reaction product in the first spiral reaction tube. The pre-polymer reaction product is continuously flowed from the first reaction tube and unreacted water from the pre-polymer reaction product is removed. The water stripped pre-polymer reaction product is continuously flowed through a second spiral reaction tube and additional alkylene oxide is continuously added to the second spiral reaction tube. The alkylene oxide reacts with the pre-polymer reaction product in the second spiral reaction tube to form a polyol. The polyol is flowed through additional spiral reaction tubes with addition of alkylene oxide and optionally additional catalyst to each of the additional spiral reaction tubes, thus forming a polyol.
    • 公开了形成蔗糖基多元醇的连续方法。 该方法包括连续形成蔗糖水溶液的步骤,其与催化剂和烯化氧连续地结合并流过第一螺旋反应管。 与蔗糖水溶液基本完全反应的环氧烷发生在第一螺旋反应管中形成预聚物反应产物。 预聚物反应产物从第一反应管连续流出,并且除去预聚物反应产物的未反应水。 水分离的预聚物反应产物连续流过第二螺旋反应管,并将另外的环氧烷连续加入到第二螺旋反应管中。 烯化氧与第二螺旋反应管中的预聚物反应产物反应形成多元醇。 多元醇通过另外的螺旋反应管流动,加入环氧烷和任选的另外的催化剂到每个附加的螺旋反应管,从而形成多元醇。
