Manufacturing method of sodium D-gluconate
I. INTRODUCTION
Sodium D-gluconate is an important raw material for the production of chemicals, which is widely used in the fields of food, medicine and chemical industry. Due to its unique properties and wide range of applications, the manufacturing method of sodium D-gluconate has attracted much attention. In this paper, the manufacturing method of sodium D-gluconate will be introduced in detail, including the steps of raw material preparation, reaction process, and post-treatment.
II. Raw material preparation
The manufacture of sodium D-gluconate requires a large number of raw materials, mainly including D-glucose, sodium hydroxide and pure water. Among them, the quality of D-glucose has an important influence on the purity and yield of the final product, so it is necessary to choose high-quality D-glucose as raw material. Meanwhile, the purity of sodium hydroxide also needs to be strictly controlled to avoid the introduction of impurities. Pure water, as the solvent, needs to be guaranteed to be pure in order to avoid adverse effects on the reaction.
III. Reaction process
The manufacture of D-gluconate is mainly by chemical synthesis, and the specific steps are as follows:
1. Add D-glucose into pure water and stir well to make glucose solution.
2. Add sodium hydroxide into pure water to make sodium hydroxide solution.
3. Slowly add sodium hydroxide solution into glucose solution while stirring to make the two fully reacted.
4. Control the reaction temperature and time so that D-gluconate is fully generated.
4. Post-treatment
After the reaction, the product needs to be post-treated to obtain pure D-gluconic acid sodium. The specific steps are as follows:
1. Perform filtration on the reaction solution to remove the impurities and unreacted raw materials therein.
2. The filtrate is concentrated to obtain a concentrate.
3. The concentrate was crystallized to obtain sodium D-gluconate crystals.
4. The crystals were dried to obtain pure sodium D-gluconate.
V. Precautions
In the manufacturing process of sodium D-gluconate, the following matters need to be noted:
1. Control the reaction temperature and time to avoid over-reaction or under-reaction.
2. Strictly control the purity of raw materials to avoid introducing impurities.
3. In the post-treatment process, it is necessary to pay attention to the operation specification to avoid the contamination or loss of the product.
VI.CONCLUSION
The manufacturing method of sodium D-gluconate mainly includes the steps of raw material preparation, reaction process and post-treatment. In the manufacturing process, parameters such as raw material purity, reaction temperature and time need to be strictly controlled to ensure the quality and yield of the product. Meanwhile, in the post-treatment process, it is also necessary to pay attention to the operation specification and safety to avoid the contamination or loss of the product. In conclusion, mastering the correct manufacturing method of sodium D-gluconate is of great significance for improving product quality and reducing production cost.
