China is the largest pentaerythritol producer in the world, with capacity accounting for more than 53% of the world's total in 2010. The strong demand of automobile and construction industries in China, together with the great need from overseas market drives China's pentaerythritol to develop quickly. Also, with technology enhancement, the quality of Chinese pentaerythritol has improved significantly in recent years, and China starts producing tripentaerythritol in 2010. With the development of pentaerythritol industry, the product structure adjustment in China will continue. It is a trend that the high-grade monopentaerythritol will dominate the domestic market and dipentaerythritol's production will increase quickly in the near future in China.
Moreover, domestic market of pentaerythritol consumption is huge too. The main consumption fields of pentaerythritol are alkyd resin, polyurethane, lubricant and rosin ester. Take alkyd resin for example, the quick development of China's paint industry stimulates the demand for alkyd resin. Compared with 2009, the consumption in alkyd resin in 2010 is higher than that in 2009. With the industrial development, CCM predicts that the consumption volume of pentaerythritol will continuously increase in the future.

Local:
Pentaerythritol (also called Tetramethylolmethane) is a polyalcohol compound containing 4 esterficable hydroxyl groups which characterize polyol functions. Almost infinite esters are available from polyol. Polyol is essential in polyurethane production. Pentaerythritol is a white crystalline odorless solid; moderately soluble in cold water, freely soluble in hot water; melting point 260 C and boiling point 276 C at 30 mm Hg. It is prepared from aldol condensations of formaldehyde and acetaldehyde. and followed Cannizaro reaction. It is used to make explosives such as pentaerythritol tetranitrate (PETN). PETN, also known as penthrite, is a white crystalline compound; melting point 139 C; explodes at 205-215C; soluble in acetone, insoluble in water. Pentolite is a highly reactive explosive composed of pentaerythritol and trinitrotoluene. Pentaerythritol is a basic material for polymer production. It is used to make alkyol resins, other coating compounds. Pentacite obtained from pentaerythritol is an alkyd resin used in coatings and printing inks. Pentaerythritol is used in the preparation of polyvinyl chloride stabilizers, antioxidants, varnishes, paints, adhesives, and other infinite derivatives. 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).
