| titleOfInvention | A kind of polyethylene glycol containing acetal bond, derivative and synthesis method thereof |
| abstract | The invention discloses a polyethylene glycol containing an acetal bond, a derivative and a synthesis method thereof. Under the condition of anhydrous inert gas, 2-ethyleneoxyethanol and acetyl chloride are used as substrates to synthesize 2-ethyleneoxyethanol Ethyl acetate; then react with allyl alcohol under ice-water bath conditions, add catalyst p-toluenesulfonic acid hydrate to synthesize 2-(1-(allyloxy) ethoxy) ethyl acetate; then under alkaline conditions Hydrolyze to obtain 2‑(1‑(allyloxy)ethoxy)ethanol; finally, in the presence of catalyst DPMK, add ethylene oxide to polymerize to obtain polyethylene glycol containing acetal bonds. The invention provides a preparation method for synthesizing polyethylene glycol containing acetal bonds and its derivatives. The double bonds at the end of the synthesized polyethylene glycol can be replaced by functional groups such as mercapto groups, and the hydroxyl groups can also be condensed by other functional groups. Substituted to obtain a series of polyethylene glycols with different functional groups at the end. Moreover, the raw materials used are relatively common, the synthesis route is simple, the pollution is low, and the reaction has high efficiency, which is beneficial to its popularization and application. |
