| titleOfInvention | A kind of preparation method of phenyl acetate compound |
| abstract | The invention discloses a preparation method of phenyl acetate compounds. It uses substituted phenol and acetic anhydride shown in formula (I) as reaction raw materials, and uses aqueous sodium hydroxide solution as solvent to carry out esterification in a tubular reactor. chemical reaction to obtain the phenyl acetate compound shown in formula (II), and the reaction formula is as follows: In formula (I) and formula (II), substituent R is hydrogen, C1-C6 alkyl, nitro, cyano, halogen, carboxyl or C1-C12 alkoxycarbonyl. The present invention adopts the method of tubular reaction which approximates plug flow. In the tubular reaction, there is almost no back-mixing of materials, the mass transfer and heat transfer efficiency is high, the occurrence of side reactions is significantly reduced, and the product yield and purity are high. |
