METHODS FOR PREPARING ACETIC ACID VIA ETHANE OXIDATION |
摘要 |
The present disclosures and inventions relate to methods for the preparation of acetic acid via the oxidation of ethane, including the preparation of high purity acetic acid that comprises very low concentrations of formic acid impurity. More specifically, described herein are methods for producing acetic acid comprising: a. producing a crude acetic acid composition comprising formic acid from ethane via ethane oxidation; and then b. purifying the crude acetic acid composition by crystallization to remove formic acid to achieve a purified acetic acid composition; wherein the formic acid is present in the purified acetic acid composition in an amount less than 0.2 % by weight, based on the total weight of the purified acetic acid composition. |
