Abstract
Official abstract text for this publication.
The invention relates to the extraction of organic compounds from mixtures of said compounds with water, using a nanoporous carbon membrane. The invention can be used in any field where it is desired to separate an organic compound of interest from water, such as the drying of alcohols or alkanes.
First claim
Opening claim text (preview).
1 . A method for extracting an organic compound from a fluid mixture of the organic compound with water, wherein the method comprises: contacting the mixture with one side of a nanoporous carbon membrane; recovering the organic compound from the other side of the nanoporous carbon membrane. 2 . The method of claim 1 , wherein the nanoporous carbon membrane is selected among a carbon nanotube membrane, a nanoporous graphene membrane, or a multilayer GO or rGO membrane. 3 . The method of claim 1 , wherein the nanoporous carbon membrane has pore size greater than about 0.9 nm and less than about 1.5 nm 4 . The method of claim 1 , wherein the nanoporous carbon membrane is activated before its use, by contacting it with a pure preparation of the organic compound to be extracted. 5 . The method of claim 1 , wherein the organic compound is an alcohol or an alkane. 6 . The method of claim 5 , wherein the organic compound is a C 1 -C 12 alcohol or alkane. 7 . The method of claim 6 , wherein the organic compound is selected from the group consisting of methanol, ethanol, propanol, butanol, ethylene glycol, propylene glycol, glycerol, methane, ethane, propane, butane and mixtures thereof. 8 . The method of any of claim 1 , wherein the nanoporous carbon membrane is placed on a porous support layer.
