A method of making a benzophenonyl (alk)acrylic ester comprising adding to a mixing chamber of a microflow reactor a benzophenone alcohol, a benzophenone alcohol or substituted benzophenone alcohol comprising at least one hydroxy moiety, one or more bases, a polar liquid, an (alk)acryloyl halide or 3-haloalkylcarboxyl halide, and an organic liquid that is immiscible with the polar liquid; and producing a product stream comprising one or more benzophenonyl (alk)acrylie esters and one or more salts of the one or more bases; wherein the product stream has an organic portion and a polar portion, the organic portion of the product stream comprising the benzophenonyl (alk)acrylic ester, unreacted benzophenone alcohol or substituted benzophenone alcohol, and organic byproducts in the product stream; and further wherein either (a) the organic liquid comprises a compound of Formula (I); or (b) the method further comprises adding a compound of Formula (I) to the product stream; or (c) the organic liquid comprises a compound of Formula (I) and the method further comprises adding a compound of Formula (I) to the product stream (I) wherein R1 is H or C1 to C4 alkyl; and R2 is C1 to C12 alkyl optionally interrupted by one or more O atoms.
制备苯基苯酮基(烯丙)丙烯酸酯的方法包括将苯基酮醇、至少含有一个羟基的苯基酮醇或取代苯基酮醇、一种或多种碱、极性液体、(烯丙)丙烯酰卤或3-卤代烷基羧酰卤添加到微流反应器的混合室中,并产生包含一种或多种苯基苯酮基(烯丙)丙烯酸酯和一种或多种碱盐的产物流;其中产物流具有有机部分和极性部分,产物流的有机部分包括苯基苯酮基(烯丙)丙烯酸酯、未反应的苯基酮醇或取代苯基酮醇以及产物流中的有机副产物;进一步,有机液体包括化合物的情况下(a);或者该方法进一步包括向产物流中添加化合物的情况下(b);或者有机液体包括化合物的情况下(a),并且该方法进一步包括向产物流中添加化合物的情况下(a),其中化合物的化学式为(I),其中R1为H或C1至C4烷基;R2为C1至C12烷基,可以由一个或多个O原子中断。
