디펜타에리트리톨 C화학적 특성, 용도, 생산
개요
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.화학적 성질
white crystalline powder용도
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.주요 응용
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.제조 방법
Dipentaerythritol is obtained as a byproduct in the manufacture of pentaerythritol; it is separated by fractional distillation.
Dipentaerythritol (DPE) has been prepared from a slurry of Pentaerythritol (PE) in sulfolane catalyzed by a low amount of sulfuric acid and was isolated with 16% yield (72% GPC purity) and 57% isolated selectivity.
