Pentaerythritol

Pentaerythritol is an organic compound that is white, crystalline and solid. It is a quadrivalent alcohol that contains four hydroxyl groups in its structure. The compound is used in the manufacture of alkyd resins, varnishes, polyvinyl chloride stabilizers, olefins antioxidant and rosin ester.

Chemical Structure

Pentaerythritol is a polyol in the neopentyl group. It has the formula C(CH2OH)4. The molecule is symmetric, with the four hydroxyl groups surrounding the central carbon atom.

Production

Pentaerythritol is produced industrially by the condensation of acetaldehyde and formaldehyde in a base-catalyzed reaction. The reaction also produces di-pentaerythritol and tripentaerythritol.

Uses

Pentaerythritol is used in the synthesis of polyesters, paints, adhesives, varnishes, and other products. It is also used as a plasticizer and a stabilizer for polyvinyl chloride.

Safety

Pentaerythritol is generally considered safe for use. However, it can cause irritation to the eyes, skin, and respiratory tract if not handled properly.
