In the production of styrene, butadiene, and vinylacetate, the stabilizer 4-tert-butylcatechol (TBC) plays a crucial role in preventing premature polymerization during storage and transport.
In order not to compromise the product quality, the TBC concentration in styrene has to be maintained above 10–15 mg/L. TBC requires oxygen to prevent the monomers from polymerizing. To control TBC depletion, close monitoring of the concentration is required.
In the case of liquefied 1,3-butadiene, TBC is added to prevent formation of peroxides and popcorn polymer. For the determination, the sample is bubbled through a solvent which absorbs the TBC while the butadiene evaporates.
If you need to monitor TBC levels in styrene, butadiene, or vinylacetate, check out the ADI 2045TI Process Analyzer.
