【Abstract】 This paper introduced an improved experiment for the preparation of Aspirin. The melting point of the product was 133℃ ～135℃ , and the IR spectra of the product matched well with the standard. The method could save time, be convenient in operation and easily controlled. It could produce higher yields.更多还原
