Summary: | 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. |
