N-butyl benzoate, also known as n-butyl benzoate, is an important organic synthetic raw material, which has a wide range of applications in the fields of medicine, perfume, dyes and so on. Below we will introduce the synthesis method of n-butyl benzoate and the matters needing attention in the synthesis process. The synthesis methods of

n-butyl benzoate mainly include ester exchange method and acid anhydride acidification method. The transesterification method is to synthesize n-butyl benzoate by the transesterification reaction of n-butanol and benzoate, which is simple to operate, but the yield is low. The acid anhydride acidification method is to use benzoic acid and n-butanol as raw materials, through the acid anhydride reaction to obtain benzoic acid n-butyl ester, the method has a higher yield, but the catalyst and reaction conditions require higher.

In the synthesis process of n-butyl benzoate, the following matters need to be paid attention to:

1. The purity of raw materials
In the synthesis process of n-butyl benzoate, the purity of raw materials has an important impact on the quality of the final product. Therefore, it is necessary to ensure that the purity of the raw materials meets the requirements before synthesis to avoid the interference of impurities on the reaction products.

2. Control
of reaction conditions In the transesterification process, the reaction temperature and pressure have an important influence on the reaction yield and selectivity. Therefore, it is necessary to strictly control the reaction temperature and pressure during the reaction process to ensure the smooth progress of the reaction. In the acid anhydride acidification method, the choice of catalyst and the reaction temperature have an important influence on the reaction rate and selectivity, so it is necessary to carefully select the catalyst and control the appropriate reaction temperature.

3. Selective
of the reaction In the synthesis of n-butyl benzoate, it is necessary to pay attention to the selectivity of the reaction and avoid the formation of by-products, thereby affecting the purity and yield of the product. Therefore, it is necessary to consider the reaction conditions and catalyst selection to ensure the efficiency and selectivity of the reaction.

n-butyl benzoate is synthesized by various methods, and attention should be paid to the purity of raw materials, the control of reaction conditions and the selectivity of reaction in the synthesis process, so as to obtain high-quality n-butyl benzoate products. It is hoped that this paper will provide reference and guidance to relevant practitioners.
