用于通过甘油的脱氧脱水生产烯丙基化合物的方法
Abstract:
本发明涉及一种用于通过甘油的脱氧脱水生产烯丙基化合物的连续流动方法，所述连续流动方法包括以下步骤：(a)通过混合甘油(1)与以下各项而形成反应溶液：#羧酸(2)，和/或#原酸三乙酯、优选原甲酸三乙酯(TEOF)；(b)将所述反应溶液进料至热分解微型反应器模块的通道的入口，其中所述通道具有不超过1000μm的内水力直径，D＝4A/P，其中A是所述通道的横断面的面积并且P是所述通道的横断面的周长，(c)通过在压力P下并且在大于200℃的热分解温度T下将所述反应溶液的流沿所述通道从所述入口驱动至出口，持续热分解时间t来使所述反应溶液暴露以进行热分解，以形成包含至少一种烯丙基化合物的热分解产物；以及在所述出口处回收所述热分解产物并且将所述至少一种烯丙基化合物与其他热分解产物分离。
Abstract(English):

The present invention concerns acontinuous-flow process for the production of allyl compounds by deoxydehydration of glycerol comprising the following steps: (a)Forming a reactive solution by mixing glycerol (1) with: a carboxylic acid (2), and/or a triethyl orthoester, preferably triethyl orthoformate (TEOF); (b)Feeding the reactive solution to an inlet of a channel of a thermolysis microreactormodule wherein the channel has an inner hydraulic diameter, D=4A/P, wherein A is the area and P the perimeter of a cross-section of the channel, of not more than 1000um, (c)Exposing the reactive solution to thermolysis by driving a flow of the reactive solution along the channel from the inlet to an outlet, for a thermolysis time, t, at a pressure, P, and at a thermolysis temperature, T, larger than 200 deg C, to form thermolysis products including at least one allyl compound; and Recovering the thermolysis products at the outlet and separating the at least one allyl compound from the other thermolysis products
