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: 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 stable hydroxyl amines to inhibit the polymerization of unsaturated compounds (e.g., vinyl monomers) wherein said stable hydroxylamine is soluble in organic solvents, particularly hydrocarbon solvents consisting of unsaturated and, therefore, polymerizable constituents.

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: Described are compositions and methods for inhibiting and retarding polymerization of a monomer composition, which use a naphthoquinone and an oxygenated aminophenol. When present in a monomer-containing composition, the combination of the naphthoquinone and oxygenated aminophenol provides an unexpected beneficial antipolymerant effect inhibiting unwanted formation of fouling polymer. The antipolymerant combination can be added to a hydrocarbon composition, such as a petroleum, that can include a polymerizable components, such as styrene, where the hydrocarbon composition is purified or processed, such as in the case of distillation.

Abstract: The present disclosure generally relates to nonylphenol-free alkoxylated 4-(alkyloxy)phenol/aldehyde resins and processes for making alkoxylated 4-(alkyloxy)phenol/aldehyde resins. The disclosure also relates to methods of breaking emulsions of oil and water comprising the dosing of an effective amount of an emulsion breaker composition into a stable emulsion to destabilize the emulsion, wherein the emulsion breaker composition comprises an alkoxylated 4-(alkyloxy)phenol/aldehyde resin.

Abstract: Described are compounds, compositions, and methods that include a nitrogen- and oxygen-containing aromatic compound, such as an aminophenol-based compound, which can be used for inhibiting polymerization of a monomer (e.g., styrene) composition. The compound includes a tertiary amine group wherein the nitrogen is attached to carbon-containing groups, and at least one of oxygen atom separated from the nitrogen by one or more carbon atoms. The antipolymerant can provide excellent antipolymerant activity in a monomer-containing 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.
