Patent ID: 10710945

Abstract:
Aromatic compositions useful in various applications, such as aromatic fluid solvents and high temperature heat transfer fluids, are provided herein. Also provided are advantageous methods for obtaining the aromatic compositions, utilizing hydroalkylation of precursor aromatic hydrocarbons such as benzene, toluene, xylene, and the like. Particularly preferred aromatic compositions include one or more of cycloalkylaromatic, dicycloalkylaromatic, biphenyl, terphenyl, and diphenyl oxide compounds. The aromatic compositions may be blended with an aromatic solvent or other aromatic fluid comprising one or more of alkylnaphthalenes, alkylbenzenes, and naphthalene, e.g., to form a useful aromatic fluid solvent, or the aromatic compositions may be utilized as high temperature heat transfer fluids (with or without additional blend components).
