Pentaerythritol is the organic compound with the formula C(CH2OH)4. This white, crystalline polyol is a versatile building block for the preparation of many polyfunctionalized compounds such as the explosive PETN and pentaerythritol triacrylate[1]. Derivatives of pentaerythritol are components of alkyd resins, varnishes, PVC stabilizers, tall oil esters, and olefin antioxidants.
Preparation
It can be prepared by condensation of acetaldehyde and formaldehyde in a basic environment.[2] The process occurs by successive aldol reactions followed by a Cannizzaro reaction. Impurities include dipentaerythritol and tripentaerythritol.[3]
