A method of performing a reaction is disclosed comprising flowing a reaction mixture () comprising HF past a compression seal () within a flow reactor (), wherein the compression seal () includes an O-ring or gasket () and where the O-ring or gasket () comprises fluoroelastomer (to include fluoroelastomers and perfluoroelastomers), while maintaining the reaction mixture comprising HF at a temperature of 50° C. or greater [generally at a temperature in the range of from 50° C. and greater (60, 70, 80, 90, 100, 120, 150, and 180° C.) up to 220° C.], using O-rings or gaskets () that comprise a fluoroelastomer having a pre-use tensile strength in the range of from 0.1 to 14 MPa measured according to IS037, and desirably further having a compressive set in the range of from 0 to 12% measured according to IS0815. 1. A method of performing a reaction having a reaction mixture comprising HF (hydrofluoric acid) in a flow reactor at a temperature of 50° C. or greater , the method comprising:{'b': 50', '40', '20', '22', '40', '30', '32', '22', '30', '32, 'flowing a reaction mixture () comprising HF past a compression seal () within a flow reactor (), the flow reactor comprising first and second reactor components () formed of one or more HF-resistant materials, the compression seal () comprising an O-ring or gasket (, ) positioned between the first and second reactor components (), the O-ring or gasket (, ) comprising a fluoroelastomer; and'}{'b': 50', '30', '32, 'maintaining the reaction mixture () comprising HF at said temperature of 50° C. or greater, advantageously at a temperature in the range of from 50 to 220° C., wherein the O-rings or gaskets (, ) comprise a fluoroelastomer having a pre-use tensile strength in the range of from 0.1 to 14 MPa measured according to ISO37.'}23032. The method according to wherein the O-rings or gaskets ( claim 1 , ) comprise a fluoroelastomer having a pre-use compressive set in the range of from 0 to 12% measured according to ISO815.35050 ...
