Dioctyl ether is a chemical compound from the group of dialkyl ethers .

Extraction and presentation

Dioctyl ether can be obtained from furfural and acetone via tetrahydrofurfuryl acetone or by reacting octyl alcohol with 1-bromooctane .

properties

Dioctyl ether is a flammable, hardly inflammable, colorless liquid that is practically insoluble in water. Its flash point is 109 ° C and the ignition temperature is 205 ° C.

use

Dioctyl ether is used as an emollient and solvent in the cosmetics industry ( e.g. for shampoos and sun cream). It is used instead of natural fats, is well absorbed by the skin, does not appear sticky and does not go rancid. It is also used in the production of nanoparticles.
