| titleOfInvention | A kind of treatment method of high concentration wastewater in citral synthesis process |
| abstract | The invention provides a method for treating high-concentration wastewater in a citral synthesis process. Using high-concentration wastewater obtained by oxidizing 3-methyl-3-butene-1-alcohol to prepare 3-methyl-3-butene-1-aldehyde as raw material, the steps include: stripping and separating alcohols contained in the high-concentration wastewater compound and aldehyde compounds, converting high-concentration wastewater into low-concentration wastewater containing acetal compounds; converting the acetal compounds in the low-concentration wastewater into 3-methyl-3-butene-1 alcohol and 3-methyl-3-butene-1-aldehyde to obtain low-concentration waste water containing hydrolyzate; the low-concentration waste water containing hydrolyzate is separated from 3-methyl-3-butene-1 alcohol and 3-methyl by stripping base-3-butene-1-aldehyde, reducing the COD of the treated wastewater to below 200ppm. The method is economical, has high processing efficiency, and converts heavy component impurities into process raw materials and products, thereby improving the separation yield. |
