Dehydrocondensation of 1 - hexanol to di - n - hexyl ether ( DNHE ) on Amberlyst 70

Conversion, selectivity, yield and kinetics of 1-hexanol liquid phase dehydrocondensation to di-n-hexyl ether (DNHE) were determined at 150-190 oC on the thermally stable resin Amberlyst 70 in a batch reactor. At 190oC, 1-hexanol conversion of about 71 %, with selectivity to ether of 87 % was obtained after 6-h reaction time. A kinetic model stemming from an Eley-Rideal mechanism in which 1-hex...

Absorption, distribution and elimination of di-ethyl ether in man.

IN 1924 Haggard published a paper on this subject having carried out his study on dogs. The mode of transfer of di-ethyl ether to and from the human subject in clinical anaesthesia has been deduced from the facts derived from his animal experiments. Since there is no assurance that this deduction is right, a human study of this kind has been awaited. The present study is intended to fill this g...

Searching for trans ethyl methyl ether in Orion KL.

We report on the tentative detection of trans ethyl methyl ether (tEME), t-CH3CH2OCH3, through the identification of a large number of rotational lines from each one of the spin states of the molecule towards Orion KL. We also search for gauche-trans-n-propanol, Gt-n-CH3CH2CH2OH, an isomer of tEME in the same source. We have identified lines of both species in the IRAM 30 m line survey and in t...

The Absorption, Distribution, and Elimination of Ethyl Ether

Predicted and experimental crystal structures of ethyl-tert-butyl ether.

Possible crystal structures of ethyl-tert-butyl ether (ETBE) were predicted by global lattice-energy minimizations using the force-field approach. 33 structures were found within an energy range of 2 kJmol(-1) above the global minimum. Low-temperature crystallization experiments were carried out at 80-160 K. The crystal structure was determined from X-ray powder data. ETBE crystallizes in C2/m,...
