| titleOfInvention | The preparation method of methyl phenyl vinyl silicone oil |
| abstract | The preparation method of methyl phenyl vinyl silicone oil of the present invention is related to LED encapsulation material preparation field, and in particular to the preparation method of methyl phenyl vinyl silicone oil, comprises the following steps：The mixture of dimethoxydiphenylsilane, octamethylcy-clotetrasiloxane, Vinyldimethylethoxysilane, the concentrated sulfuric acid and toluene is added into the four-hole boiling flask equipped with condensation reflux unit, dropping funel, agitating device and thermometer, 1 h is stirred in 30 45 DEG C, then by temperature to 35 50 DEG C, deionized water is added dropwise in 12 h, it is added dropwise to complete the rear h of temperature rising reflux 4 and condensation reaction is hydrolyzed, obtains hydrolysis mixture；Hydrolysis mixture is stood and is cooled to room temperature, organic layer is then demultiplex out and organic layer is washed with deionized to neutrality, then 0.1 1g potassium hydroxide is added to organic layer, heating azeotropic 4 h of backflow, obtains azeotropic phegma；Work flow of the present invention is simple, easy and safe to operate, and can substantially reduce production cost, improves production efficiency and product quality. |
