Cas No. :1615-02-7
It is obtained by reacting p-chlorobenzaldehyde with acetic anhydride. The p-chlorobenzaldehyde, acetic anhydride and sodium acetate were reacted together at 180 ° C for 13 h. After the reaction, it was slightly cold, poured into water, filtered, and the filter cake was washed with water and repeatedly dissolved with ammonia water until only a small amount of brownish yellow viscous remained. The obtained ammonium salt solution was filtered, and p-chlorocinnamic acid was re-precipitated with 3N dilute sulfuric acid, and dried by filtration to obtain a product. The yield is about 80%.
An organic synthesis intermediate for the synthesis of p-chloropropionic acid to produce a herbicide, Mai Di San. For the synthesis of herbicides. It is slightly harmful to water. Do not let undiluted or large quantities of products come into contact with ground water, waterways or sewage systems. If there is no government permission, do not discharge materials into the surrounding environment.Stable under normal temperature and pressure to avoid oxide contact. Acute toxicity: LD50: 1622mg/kg in mice; LD: >350 mg/kg in rats: stimulating effect on skin and mucous membranes. Keep the container sealed and store in a cool, dry place. |
