| titleOfInvention | Styrene monomer comprising polymerizable double bond and chain transfer sulfydryl and preparation method thereof |
| abstract | The invention relates to a styrene monomer comprising a polymerizable double bond and chain transfer sulfydryl and a preparation method thereof and belongs to the field of organic synthesis. The structural formula of the styrene monomer is shown in the specifications. The preparation method comprises the following steps of: forming a phase transfer catalytic system by using vinyl benzyl chloride and triethylamine; adding a small amount of phenothiazine; reacting at the temperature of between 70 and 90 DEG C for 1.5 hours under stirring; adding sulfydryl sodium propionate or sulfydryl potassium propionate and continuously reacting for 6 to 25 hours; after the reaction is stopped, extracting by using a proper amount of petroleum ether; washing with a great deal of distilled water for 4 to 5 times until an aqueous phase is clear; separating an oil phase out; adding a proper amount of anhydrous calcium chloride (CaCl2) and drying; cooling to separate a solid product out; and recrystallizing the solid product by using the petroleum ether to obtain sulfydryl propionic acid paravinyl benzyl ester. In the styrene functional monomer obtained by the method, the double bond and sulfydryl cannot be subjected to an addition reaction at normal temperature; and storage stability is extremely high. |
