Description
General description
Oxalic acid dihydrate is a promising candidate as a phase change material (PCM) for use in thermal energy storage (TES) technology due to its high heat of fusion and energy storage density/price ratio in comparison to other salt hydrates PCMs.[4]
Application
Oxalic acid dihydrate may be used:
• As a catalyst in the preparation of tetrahydroquinoline derivatives via imino Diels-Alder reaction.[5]
• As a homogeneous catalyst in the preparation of highly functionalized piperidines via multi-component reaction.[6]
• As an oxidant for the formation of triazolinediones from corresponding urazoles and bisurazoles via oxidation.[7]
• In the transformation of thiols to nitrosothiols by reacting with sodium nitrite.[8]
