Introduction

γ- Butyl lactone (GBL) is an important raw material for chemical production, widely used in fields such as medicine, pesticides, plastics, fibers, etc. With the continuous progress of technology, the manufacturing methods of GBL have also been continuously developed and optimized. This article will introduce a common GBL manufacturing method

2. Materials and Methods 

2.1 Materials 

The raw materials required for this experiment are succinic acid, methanol, and sodium hydroxide

2.2 Equipment 

Experimental equipment includes reaction kettle, agitator, thermometer, condenser, water distributor, etc

2.3 Manufacturing Method: Add succinic acid and methanol in a certain molar ratio to a reaction vessel, stir and heat to a certain temperature, then slowly add sodium hydroxide solution, control the reaction temperature within a certain range, and after a certain reaction time, distill and separate to obtain GBL product

3. Results and Discussion 

3.1 Effect of Reaction Temperature 

In the experiment, we found that reaction temperature has a significant impact on the yield of GBL. When the reaction temperature is low, the reaction speed is slower and the yield is lower; When the reaction temperature is high, although the reaction rate accelerates, more by-products are produced, which affects the purity of GBL. Therefore, selecting the appropriate reaction temperature is the key to ensuring yield and purity

3.2 The influence of raw material ratio 

The raw material ratio is also an important factor affecting the yield of GBL. When the molar ratio of succinic acid to methanol is too low, it can lead to an excess of methanol and increase production costs; When the molar ratio is too high, it can lead to an excess of succinic acid, affecting the purity of GBL. Therefore, selecting the appropriate raw material ratio is also the key to improving yield and purity

3.3 Product Purity Detection 

We have tested the purity of GBL products using analytical methods such as high-performance liquid chromatography. The results show that the GBL products obtained by the above manufacturing methods have high purity and meet industrial production requirements

4. Conclusion: This article introduces a common GBL manufacturing method and verifies its feasibility through experiments. The experimental results indicate that selecting the appropriate reaction temperature and raw material ratio is the key to improving the yield and purity of GBL. Meanwhile, the purity of GBL products can be effectively detected using analytical methods such as high-performance liquid chromatography. This method has the advantages of simple operation, easy availability of raw materials, and low cost, making it suitable for industrial production.
