Description of key information
Additional information
Diisopentyl ether is a colorless liquid with a characteristic, fruity odour and has a melting point of below -80°C and a boiling point of 180.4°C at 101.3 kPa. The density of diisopentyl ether at 20°C is 0.7762 g/cm3 (Laus GmbH, 2011).
The vapour pressure is 202 Pa at 20°C.The octanol/water partition coefficient (log Pow) is 5.1, the water solubility is 27.5 mg/L at 20ºC (Laus GmbH, 2011). The viscosity is1.012 mPa.s at 20°C (Lange's Handbook of Chemistry, 2001).
In accordance with column 2 of REACH Annex VII, data on the particle size are not needed as the substance is a liquid. The surface tension is 71.97 mN/m at 20°C and a concentration of 11.9 mg/L. Diisopentyl ether is therefore not considered to be surface active (Laus GmbH, 2011). As the stability of diisopentyl ether is not considered to be critical, the solubility in organic solvents and the identity of relevant degradation products do not need to be determined. Due to a lack of relevant functional groups, the dissociation constant does not need to be determined.
The flash point is 56.3ºC at 101.3 kPa (Laus GmbH, 2011). The classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 is H226, flammable liquid. According to Annex I of Directive 67/584/EEC, the substance is classified as Flammable Liquid (R10).
The self-ignition temperature of the substance is 160°C at 101.3 kPa (Laus GmbH, 2011).
Based on the molecular structure, water reactivity, pyrophoricity, explosive and oxidising properties are not expected (Laus GmbH, 2011).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
