    IPC: C07C45/63

    Abstract: The present disclosure relates to a process for the manufacturing of a 3-5 halopropionylhalide, wherein the process comprises the steps of: a) providing a flow reactor comprising a reaction chamber; b) providing reactants comprising: i. acrylic acid; ii. a reaction co-agent selected from the group consisting of N,N-0 disubstituted amides; and iii. a halogenating agent; and c) incorporating the reactants into the reaction chamber of the flow reactor, thereby forming a reaction product stream comprising a 3-halopropionyl-halide; wherein the molar ratio of acrylic acid to the halogenating agent is 1 to at least 5 0.8; wherein the temperature of the reaction chamber of the flow reactor is greater than 60° C.; and wherein the residence time of the reaction product stream comprising the 3-halopropionylhalide in the reaction chamber of the flow reactor is greater than 10 minutes.

    Abstract: The present disclosure relates to a process for the manufacturing of an acid halide, wherein the process comprises the steps of: a) providing a flow reactor comprising a reaction chamber; b) providing reactants comprising: i. a carboxylic acid; ii. a reaction co-agent selected from the group consisting of N,N-disubstituted amides; and iii. a phosphoryl halide; c) incorporating the reactants into the reaction chamber of the flow reactor, wherein the molar ratio of the carboxylic acid to the phosphoryl halide is 1 to at least 0.8, and the molar ratio of the carboxylic acid to the co-agent is 1 to at least 0.5; and d) producing a reaction product stream comprising the acid halide. In another aspect, the present disclosure is directed to the use of a phosphoryl halide for the manufacturing of an acid halide in a flow reactor.

    IPC: C07C67/14

    Abstract: 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)acrylic 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.
