Dipentaerythritol Usage And Synthesis |
Description | Dipentaerythritol, also known as 2,2-[oxybis(methylene)- bis[2-hydroxymethyl]-1,3-propanediol, is a byproduct of pentaerythritol production. Because of its low solubility in water (0.22 g/ 100 g H2O at 20 ℃ and 10.0 g/100 g H2O at 100 ℃) it can be separated from pentaerythritol by fractional crystallization. The yield can be increased by changing the ratio of formaldehyde/ acetaldehyde towards stoichiometric. Adding pentaerythritol before starting the reaction also increases the yield. An effective method is to use acrolein instead of acetaldehyde. Dipentaerythritol can be produced intentionally from pentaerythritol by acid catalysis. Dipentaerythritol is purified as a coproduct by many pentaerythritol producers. |
Chemical Properties | white crystalline powder |
Uses | 2,2''-(Oxybis(methylene))bis(2-(hydroxymethyl)-propane-1,3-diol) is used in preparation of new type of explosion-proof and flame-retardant tape material for cables. |
Application | Dipentaerythritol (DPE) is an attractive raw material used for the production of polyesters, polyethers, polyurethanes, alkyd resins, photosensitive resin film. DPE is also employed in a wide range synthesis of specialty chemicals such as lubricants, coatings, adhesives, plasticizers and cosmetics. |
Application | PVC stabilizers based on calcium – zinc carboxylates use micronized dipentaerythritol as costabilizer to improve the thermal stability of PVC during processing. This system grows fast in economic significance at the expense of leadbased stabilizers due to environmental reasons. Micronized dipentaerythritol is also used in intumescent paints. Synthetic lubricants are another important application for dipentaerythritol. The C5 – C10 esters are used as lubricants in jet engines and refrigerators. Rosin esters made from dipentaerythritol have a higher softening point than rosin esters from pentaerythritol. |
