THEN CONVERTED TO ETHANOIC ACID, WHICH IS THEN SUBJECT TO A TWO STAGE HYDROGENATION PROCESS BY WHICH AT LEAST A PART OF THE ETHANOIC ACID IS CONVERTED BY A PRIMARY HYDROGENATION PROCESS TO ETHYL ETHANOATE, WHICH ETHYL ETHANOATE IS CONVERTED BY A SECONDARY HYDROGENATION PROCESS TO PRODUCE ETHANOL....
EP02060555 describes a process for esterifying ethanoic acid and an alcohol to form ethanoates. The ethanoates are hydrogenated to produce ethanol. The need remains for improving the recovery of ethanol from a crude product obtained by reducing alkanoic acids, such as acetic acid, and/or other...
nconverted to ethanoic acid, which is then subject to a two\nstage hydrogenation process by which at least a part of the ethanoic acid is\nconverted by a primary hydrogenation process to ethyl\nethanoate, which ethyl ethanoate is converted by a secondary hydrogenation\nprocess to produce ethanol...
then converted to ethanoic acid, which is then subject to a two stage hydrogenation process by which at least a part of the ethanoic acid is converted by a primary hydrogenation process to ethyl ethanoate, which ethyl ethanoate is converted by a secondary hydrogenation process to produce ethanol....
CONSTITUTION:(S)-(-)-2,4,4-Trimethyl-2-cyclohexen-1-ol expressed by formula I is made to reacted with triethyl orthoacetate to form ethyl 2-[(1R)-2, 6, 6- trimethyl-2-cyclohexen-1-yl]-ethanoate expressed by formula II, which is then successively converted into a tosylate and a ...
In those reactions where single carbocation intermediates are to be expected, excellent yields of a single ester are often obtained. For example ethyl ethanoate was prepared in 92% yield (based on ethanoic acid) with 96% selectivity, from ethanoic acid and excess ethene using Al 3+ ion-...
then converted to ethanoic acid, which is then subject to a two stage hydrogenation process by which at least a part of the ethanoic acid is converted by a primary hydrogenation process to ethyl ethanoate, which ethyl cthanoatc is converted by a secondary hydrogenation process to produce ethanol...
Process for the production of ethanol from H2 ethanoic acid, characterized by the following steps: 1) introducing ethanoic acid, together with methanol and / or ethanol, into an esterification reactor containing an esterification catalyst to produce methyl ethanoate and / or ethyl ethanoate, 2) ...
8. A process according to any of the preceding claims wherein the molar ratio of Hto [methyl ethanoate and ethyl ethanoate] that is introduced into the hydrogenation unit, is greater than 2:1; and is less than 100:1. 9. A process according to any of the preceding claims wherein a ...
