Abstract
The present invention provides a method for purifying an organic compound, by which an organic compound having a reduced lead content is obtained from an organic compound that contains a lead component as an impurity. In this method for purifying an organic compound, the organic compound that contains a lead component is irradiated with ultraviolet light, and the lead component is subsequently removed from the organic compound. The present invention also provides a method for producing an organic compound, said method comprising purification of the organic compound by means of the above-described method for purifying an organic compound.
Claims9
A method for purifying an organic compound, comprising an organic lead component as an impurity,
- the method comprising dissolving the organic compound comprising the organic lead component in an organic solvent to form a solution;
- wherein the organic lead component comprises a lead-carbon bond, and
- wherein a concentration of the organic lead component in the organic compound before dissolving the organic compound in the organic solvent is within the range of 1 ppb to 1000 ppm on a mass basis;
- and
- irradiating the solution with ultraviolet rays thereby cleaving the lead-carbon bond of the organic lead component and thereby forming a second lead component, and
- removing the second lead component from the solution irradiated with ultraviolet rays.
