Considering　the　low　conversion　and　long　reaction　time　in　scaling　up　reaction　in　batch　reactor,　the　organocatalyzed　epoxidation　reaction　of　styrene　was　intensified　under　continuous　flow　conditions　using　a　commercial　fluidic　reactor　(Corning　Advanced　Flow　G1　Reactor).　After　investigating　the　effect　of　reaction　temperature,　catalyst　amount,　MeCN/t-BuOH　ratio,　FO/FAB　(buffer　solution　amount),　total　feed　flow　rate　and　operating　mode　on　the　epoxidation　reaction,　the　optimal　reaction　conditions　were　identified　under　continuous　flow　conditions.　Upon　optimization,　high　conversion　and　excellent　selectivity　with　short　reaction　time　(3.17 min)　can　be　obtained.　We　successfully　developed　a　process　for　the　rapid　and　continuous　epoxidation　of　styrene　using　an　organocatalyst　with　hydrogen　peroxide　as　the　oxidant.　Compared　with　the　batch　conditions,　the　continuous　flow　reactor　can　exhibit　unique　advantages　including　high-speed,　safety,　continuousness　and　absence　of　amplifying　effect,　which　will　be　significant　for　the　industrial　production　of　epoxides.　©　2020,　Akadémiai　Kiadó.
