Abstract: Through an anthropomorphic approach, this article adopts the first-person perspective of Pentaerythritol as a child, narrating its story of making friends and engaging in lively dialogues to introduce the chemical reactions between Pentaerythritol and other compounds, as well as the applications of the resulting products. Detailed explanations are provided on the esterification of Pentaerythritol with fatty acids, its nitration with nitric acid, chelation with zinc oxide, involvement in the synthesis of ibuprofen through ketal condensation, and the preparation of Pentaerythritol and dipentaerythritol. Additionally, the article briefly describes the lubricating properties of Pentaerythritol esters and their applications in daily chemicals and aerospace, the explosive nature of Pentaerythritol nitrate, the thermal stabilizing effect of Pentaerythritol zinc, and the uses of related compounds.

Key words: Pentaerythritol, Lubricant, Explosive, Thermal stability, Popularization of science
