1,3-Propanediol, 2,2'-[oxybis(methylene)]bis[2-(hydroxymethyl)-: ACTIVE
OCCURS IN TECHNICAL PENTAERYTHRITOL. ... THE MOLECULE CONTAINS SIX PRIMARY HYDROXYL GROUPS, ALL ESTERIFIABLE.
CONDENSATION PRODUCTS OF DIPENTAERYTHRITOL WERE TREATED WITH DIOXIRANE CMPD TO GIVE DENATURED POLYESTERS. THE DENATURED POLYESTERS, TOGETHER WITH NITROCELLULOSE WERE DISSOLVED IN ORG SOLVENTS TO PRODUCE NAIL LACQUERS.
MONOBASIC OR DIBASIC ACID DIPENTAERYTHRITOL ESTERS ADDED TO COSMETIC BASES CONTAINING FATTY ACIDS IMPROVE THE PROPERTIES OF THESE BASES WITH RESPECT TO THE CHEMICAL STABILITY & ADHESION TO SKIN.
DIPENTAERYTHRITOL ESTERS ARE USED IN HAIR RINSES.
Anwendungen
BeschreibungDas Bis-[4-(N,N-dimethylamino)-phenyl]-methan bildet schwach gelbe, in Wasser unlösliche Kristalle. Es wird als Reagens auf Blei(IV)-oxid verwendet, mit dem es eine intensiv blaue Verbindung bildet. Das Reagens dient besonders in der qualitativen Analyse
BeschreibungDipentaerythritol, 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.
Verwenden2,2''-(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.
Darstellung
synthetischeDipentaerythritol 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.synthesis of dipentaerythritol from pentaerythritol under acidic conditions
