Description
Polyethylene glycol 2000, ROTIPURAN®, is a polyethylene glycol grade with CAS number 25322-68-3 and EG nr. 500-038-2. The stated molar-mass range is 1800–2200 g/mol, the density is 1,2 g/cm³ and the flash point lies between 240 and 270 °C. This article is of the ROTIPURAN® quality. Polyethylene glycol 2000 is a polymeric glycol whose average molecular weight is defined by the 1800–2200 g/mol window; the density of 1,2 g/cm³ supports conversion between mass and volume from the published figure. The flash-point interval of 240 to 270 °C is recorded for thermal handling of the bulk material. 500-038-2 and the 1800–2200 g/mol range together on one labelled pack. Laboratories that specify Polyethylene glycol 2000 at this molar-mass band can draw on the published density of 1,2 g/cm³ and the 240–270 °C flash point when relating mass, volume and thermal limits for.
