LCY’s Guide to Pentaerythritol and Dipentaerythritol Application and Properties

2024-04-16

The Application of Pentaerythritol and Dipentaerythritol

Pentaerythritol is a polyol organic compound with the formula C5H12O4. It is soluble in water, methanol, glycerol, etc., with the appearance of white crystals; the molecular formula of dipentaerythritol is C10H22O7. It is slightly soluble in water and has the appearance of white crystalline powder.

Pentaerythritol and dipentaerythritol are used in the production of resins, lubricants, antioxidants, etc. They are also used as a raw material for the synthesis of rosin ester, which is commonly applied in paint, desiccants and adhesives, boasting a wide range of industrial and everyday applications.


Enhance the stability for the Rosin ester by Pentaerythritol and Dipentaerythritol

Rosin esters are compatible with many polymers and are very effective tackifiers. Rosin ester was primarily derived from natural pine trees in the earlier days. Natural rosin ester is yellow and requires the addition of modified additives to enhance stability. Such a requirement has led to the industry’s gradual shift to using chemical raw materials to produce rosin ester, with pentaerythritol and dipentaerythritol being the most popular choices.


High-end applications:Aviation lubricants and photosensitive coatings

Dipentaerythritol is non-toxic and non-hygroscopic, which makes rosin ester made from dipentaerythritol more stable. When high-purity dipentaerythritol is used to produce rosin ester, it significantly reduces the production cost and enhances product quality. It is commonly used in high-end applications such as aviation lubricants and photosensitive coatings.


Environmentally-Friendly Manufacturing Process of Pentaerythritol and Dipentaerythritol

Pentaerythritol is manufactured from formaldehyde and acetaldehyde in the presence of sodium hydroxide, with dipentaerythritol and sodium formate obtained as the byproduct of the manufacturing process. Formaldehyde and acetaldehyde are synthesized from methanol and ethylene respectively:

LCY applies methanol from natural gas. Methanol is then converted into formaldehyde through dehydrogenation, with the separated hydrogen used as fuel. The production process can produce high-purity pentaerythritol and dipentaerythritol while reducing environmental impact


Must-knows before purchasing pentaerythritol or dipentaerythritol

Rosin ester made from pentaerythritol and dipentaerythritol has good thermal stability, making it less susceptible to deterioration due to environmental factors during industrial application or storage. Rosin ester produced from the white translucent pentaerythritol and dipentaerythritol is relatively transparent with a slight pine scent and can be used by a wide range of industries.
