Use of Pentaerythritol

Pentaerythritol, molecular formula C5H12O4, is white crystals or powders, which is flammable, and easily esterified by general organic. It is widely used in paint industry to produce alkyd resins, synthetic high-grade lubricants, plasticizers, surfactants, medicines, explosives and other raw materials.

Storage method:

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. It should be stored separately with oxidants and acids, and should not be mixed. Equipped with the corresponding variety and quantity of fire fighting equipment. The storage area should be equipped with suitable materials to accommodate leakages.

Plastic bags, polypropylene woven bags or gunny bags is used to package, which is 25kg each. Pentaerythritol dust can form an explosive mixture with air when its concentration in the air is over 30g/m3, and explosion occurs when the temperature exceeds 400℃. Therefore, it is advisable to store in a cool, dry and ventilated place, having the features of the damp-proof and fire-proof. Storage and transportation should be in accordance with general chemical regulations.

Main uses:

Pentaerythritol is mainly used in paint industry. It can be used to manufacture alkyd resin coatings. It can improve the hardness, gloss and durability of coatings film. It is also used as raw material of rosin resin for color paint, varnish and printing ink, and can be used to produce dry oil, smoldering paint and aviation lubricant. Fatty acid esters of pentaerythritol are highly effective lubricants and plasticizers of polyvinyl chloride, and their epoxy derivatives are raw materials for the production of non-ionic surfactants. Pentaerythritol is easy to form complex with metal and is also used as hard water softener in detergent formulation. In addition, it is also used in pharmaceutical and pesticide production. Pentaerythritol molecule contains four equivalent hydroxymethyl groups with high symmetry, so it is often used as raw material for the preparation of multifunctional compounds. Pentaerythritol tetranitrate (PETN) can be prepared by nitration. It is a kind of strong explosive. Pentaerythritol triacrylate (PETA) can be obtained by esterification and used as paint.

The intumescent flame retardant can be obtained by mixing with ammonium polyphosphate (APP) as a flame retardant of adhesives. It is also used as a crosslinker of polyurethane to provide branched chains in polyurethane.
