<p>Purifying acetone To obtain acetone with a greatly reduced impurities content, the mixture of acetone, water and trace impurities, resulting from treating the raw acetone with basic reagents, is subjected in one operation to vacuum rectification. As a result, the head product is non-purified acetone with light carbonyl compounds, the still product is water and heavy impurities, and the liquid phase side fraction is high purity acetone.</p> |
