| titleOfInvention | Method for improving yield of prenol prepared by chlorination process |
| abstract | The invention discloses a method for improving the yield of prenol prepared by a chlorination method. When the prenol is prepared by the existing chlorination method, about 10 percent of 3-chloroprenol generated in the chlorination process is not a target product, the yield of the prenol is limited, and extra more solid wastes are generated. According to the method, 3-chloroisoamylene and 1-chloroisoamylene obtained by chloro addition reaction are not separated, and anhydrous formate or acetate is directly added for esterification; and then carrying out hydrolysis reaction in an alkali solution, converting the prenol formate or prenol acetate into prenol, converting 3-chloroisopentene into methyl butenol, rectifying the obtained organic layer to separate out methyl butenol, toluene and prenol, and recycling the methyl butenol and the toluene to the chloro addition reaction. The invention avoids the traditional rectification of the chloro isoamylene, thereby solving the problems of equipment corrosion, toxic chloride, damage to the chloride due to high temperature and the like caused by the rectification of the chloro isoamylene. |
