Abstract

Systems and methods are disclosed for synthesizing one or more simple alcohols from mixtures including organic acids, water, and a superparamagnetic catalyst exposed to fluctuating magnetic fields under ambient conditions.

Claims (13)

1. A method for synthesizing an alcohol, the method comprising:

contacting a carboxylic acid with water to form a first mixture;

contacting the first mixture with a superparamagnetic catalyst to form a second mixture, wherein the superparamagnetic catalyst comprises at least one ferromagnetic compound and at least one paramagnetic compound; and

exposing the second mixture to a fluctuating magnetic field to form a third mixture thereby yielding the alcohol,

wherein the method is carried out at ambient conditions.

2. The method of claim 1 , wherein contacting a carboxylic acid with water comprises contacting acetic acid with water, and

wherein yielding the alcohol comprises yielding one of ethanol or methanol.

3. The method of claim 1 , wherein contacting a carboxylic acid with water comprises contacting a dicarboxylic acid with water.

4. The method of claim 1 , wherein contacting a carboxylic acid with water to form a first mixture comprises contacting the carboxylic acid with water to form the first mixture having a molar ratio of water to the carboxylic acid of about 1.5:1 to about 4:1.

5. The method of claim 1 , wherein yielding of the alcohol depends at least in part on the carboxylic acid and a molar ratio of water to the carboxylic acid.

6. The method of claim 1 , wherein exposing the second mixture to a fluctuating magnetic field comprises exposing the second mixture the fluctuating magnetic field having a field strength of at least about 1 milliTesla.

7. The method of claim 1 , wherein exposing the second mixture to a fluctuating magnetic field comprises exposing the second mixture to the fluctuating magnetic field having a fluctuation frequency of about 10 Hz to about 2000 Hz.

8. The method of claim 1 , wherein exposing the second mixture to a fluctuating magnetic field comprises exposing the second mixture to the fluctuating magnetic field for about 10 minutes to about 30 minutes.
