| titleOfInvention | A kind of preparation method of chlorobenzene Grignard Reagent crystal product |
| abstract | The present invention discloses a kind of preparation method of chlorobenzene Grignard Reagent crystal product, belongs to Grignard Reagent preparing technical field.The method comprises the steps of firstly, preparing bromobenzene Grignard Reagent and 1, 2 Bromofume Grignard Reagent, then under nitrogen protection, chlorobenzene and magnesium chips are added in anhydrous ether, it is added as the bromobenzene Grignard Reagent bulk crystals of initiator or 1, 2 Bromofume Grignard Reagent bulk crystals, it is then slowly heated to reflux state, keep 2~4h, obtain the crude product containing chlorobenzene Grignard Reagent, after filtering, filtrate containing chlorobenzene Grignard Reagent is made to the saturated solution of ether, then a large amount of blocky chlorobenzene Grignard Reagent crystal is precipitated after preserving 48h under 20 DEG C~25 DEG C low temperature.The present invention has the technical characterstics such as raw material is easy to get, operational sequence is simple, raw material availability is high and product yield is higher, is suitble to industrialized production. |
