PENTAERYTHRITOL (also called Tetramethylolmethane) is a polyalcohol compound containing 4 esterficable hydroxyl groups, which favor its own fuctions. It is a white crystalline odorless solid moderately soluble in cold water, freely soluble in hot water. It is used to make the explosive pentaerythritol tetranitrate (PETN) and in the manufacture of alkyol resins and other coating compounds. It is produced from formaldehyde and acetaldehyde. There are commercially three grades of pentaerythritol: mono ( 98 percent, with di- and tripentaerythritol impurities), technical (88 percent, with 8 to 10 percent dipentaerythritol, balance tri-) and nitration (99 percent, with di- and tripentaerythritol impurities).
