Pentaerythritol

About Pentaerythritol

Pentaerythritol is an organic compound with the chemical formula CHO. It is a white, crystalline, odorless solid with a slightly sweet taste. Structurally, it contains four hydroxyl (OH) groups attached to a central carbon atom, making it a tetrafunctional alcohol.

It is typically produced via the reaction of formaldehyde and acetaldehyde in the presence of a base catalyst. Due to its high functionality and stability, it is widely used in the production of alkyd resins, synthetic lubricants, and explosives like PETN.
