Abstract: |
|||
| This invention relates to preparing high-efficient insecticide O-alkyl O-aromatic base S-propyl phosphoric ester (VI). In this process, it makes O,O-dipropyl O-aromatic base thiophosphate and phosphorus oxytrichloride occur isomerization chlorination reaction, and then reacting with alcohol to produce (VI). This process is simple in operating, the product has high purity. | |||
