| titleOfInvention | A kind of synthetic method of phenethyl acetate |
| abstract | The invention discloses a kind of synthetic method of phenethyl acetate, benzyl carbinol, acetic anhydride, Na 2 SiO 3 ·9H 2 0、Si0 2 、H 2 PtCl 6 、NaBH 4 For primary raw material；Tradition prepares phenethyl acetate and often uses the strong acid catalysts such as sulfuric acid, phosphoric acid, not only because caused by side reaction mostly product quality it is low, but also serious equipment is brought to corrode.Synthesis technology of the invention is using benzyl carbinol and acetic anhydride in catalyst Pt/Si0 2 Under the action of by nucleophilic substitution obtain phenethyl acetate, benzyl carbinol esterification uses effective catalyst, selects dichloroethanes to replace aromatic hydrocarbon as reaction dissolvent, esterification effect is good, and yield and purity all greatly improve. |
