  • Additives to remediate DVB cross-linking and insoluble polymer formation in the styrene process
    Patent number: 11661496
    Abstract: A method of reducing the fouling in a process for the production of styrene, the method comprising: introducing an additive into a stream comprising styrene and byproduct divinyl benzene (DVB), wherein the additive comprises: at least one chemical compound comprising one or more functional groups selected from amines, alcohols, amino-alcohols, labile C—C, esters, carbamates, aldehydes, ketones, acids, acetates, benzoates, labile hydrogen, and combinations thereof, and having a boiling point greater than or equal to 170° C. and within 10, 20, 30, 40, 50, or 60° C. of the boiling point of divinyl benzene (DVB) (which is 195° C.), wherein the at least one chemical compound is active to inhibit divinyl benzene (DVB) crosslinking. A system for carrying out the method is also provided.
