Abstract: Disclosed herein are systems and methods for monitoring and controlling a nitroxide-based polymerization inhibitor in vinyl-based monomers. A dosage of the nitroxide-based polymerization inhibitor is provided in the vinyl-based monomers. A residual concentration of the nitroxide-based polymerization inhibitor is measured substantially in real time, and an optimized dosage of the nitroxide-based polymerization inhibitor is provided in response to the measured residual concentration.

Abstract: The present invention generally relates to compounds and methods for preventing fouling caused by the radical polymerization of unsaturated compounds, particularly vinyl monomers. More particularly, it relates to the use of hindered hydroquinones to inhibit the polymerization, which result in the fouling of process equipment, and prematurely consume the vinylic monomer products.

Abstract: Disclosed herein are compositions including between 20 wt % and 50 wt % of a nitroxyl compound such as 2,2,6,6-tetramethylpiperidinyl-1-oxyl. The compositions are stable under field conditions of transportation and storage. The compositions remain homogeneous and pumpable or pourable at temperatures between −20° C. and 60° C., even when temperatures fluctuate in this range over a period of 10 days to 5 years, and even where the container used to transport and store the composition is made from metal or includes a metal surface contacting the composition.

Abstract: Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition, which use an N—O polymerization inhibitor, a quinone methide polymerization retarder, and an amine stabilizer having a primary and/or secondary amine group. In a mixture, the amine-based stabilizer can prevent antagonistic effects and can provide greater antipolymerant activity. In turn, the mixture inhibits apparatus fouling and improves the purity of monomer streams.

Abstract: The present invention generally relates to compounds and methods for inhibiting the radical polymerization of unsaturated compounds, particularly vinyl monomers. More particularly, it relates to the use of cinnamyl quinone methides to inhibit the polymerization of unsaturated hydrocarbon compounds (e.g., vinyl monomers) soluble in organic solvents, particularly hydrocarbon streams.
