설명

일반 설명

Dowtherm^® A is a thermally stable organic heat transfer fluid composed of a eutectic mixture of highly stable compounds, biphenyl, and diphenyl oxide. Dowtherm^® A is suitable for high-temperature heat transfer applications up to 400 °C. This fluid can be used in both liquid and vapor phase systems.

애플리케이션

Dowtherm^® A can be used as a high boiling solvent in cyclization reactions. For example, it is used to synthesize:      

• 1-Hydroxy-5-methoxy-1,2-dihydrobenzo[f][2,7]naphthyridines from 2-chloro-3-formyl quinolines.     
• Isoindolinone derivatives via intramolecular Diels–Alder cycloaddition reactions of substituted pyridazines.
• Phosphorylated azaheterocycles from 2-diethoxyphosphoryl-3-methoxyacrylate via intramolecular cyclizations under thermal conditions.
