我们在这里报道了一种连续的方法，其中葡萄糖通过在400 ° C和30 MPa下与超临界水反应转化为高达50重量%的赤藓糖。该方法是非催化的，并且连续操作，反应停留时间低至0.11 s。赤藓糖在这些条件下是稳定的，并且其选择性在50至90重量%的葡萄糖转化率范围内仅从约50至45重量%轻微变化。该方法与其它常规方法相比具有快速、连续的优点，并可获得较高的赤藓糖产率。此外，减少了有毒化学品的使用，并促进了产物分离。
We here report a continuous method in which glucose is converted by reaction with supercritical water at 400 °C and 30 MPa, to erythrose in as high as 50 wt %. This method is noncatalytic and operates continuously with a reaction residence time of as low as 0.11 s. Erythrose is stable under these conditions and its selectivity changes only slightly from about 50 to 45 wt % over the range of glucose conversion from 50 to 90 wt %. This method has an advantage over other conventional methods in that it is rapid and continuous and results in comparative high yields of erythrose. Furthermore, the use of toxic chemicals is reduced and product separation is facilitated.
