2. **Epoxidation Reaction**
The most common method for producing ESBO is the epoxidation of soybean oil using peracids.Peracids are the most common peracids used to epoxidize soybean oil. For example, performic acid or peracetic acid can be used.Peracetic or performic acids can be used, for example. In the case of using peracetic acid, the reaction is typically carried out in the presence of a catalyst.Peracetic acid is usually used in conjunction with a catalyst. The reaction mechanism involves the attack of the peracid on the double bond of the unsaturated fatty acid in soybean oil, resulting in the formation of an epoxy group.The reaction is triggered by the peracid attacking the double bond in the unsaturated fatty acids in soybean oil. This results in the formation an epoxy group.
The reaction conditions are crucial.The conditions of the reaction are critical. The reaction temperature usually ranges from 50 - 70 degC.The reaction temperature is usually between 50 and 70 degC. If the temperature is too low, the reaction rate will be slow, and incomplete epoxidation may occur.If the temperature is low, the reaction will be slow and incomplete epoxidation can occur. On the other hand, if the temperature is too high, side reactions such as the hydrolysis of the epoxy groups may take place.If the temperature is too low, the reaction rate will be slow and incomplete epoxidation may occur. The reaction time also depends on factors like the reaction temperature and the amount of catalyst used, usually ranging from 2 - 6 hours.The reaction time is also dependent on factors such as the reaction temperature and amount of catalyst, which can range from 2 to 6 hours.
After the reaction is complete, the product needs to be purified.Purification is required after the reaction has been completed. This often involves steps such as washing with water to remove unreacted peracids and other water - soluble impurities, followed by drying to remove any remaining water.Purification often involves washing the product with water to remove peracids that have not yet reacted and other water-soluble impurities.

1. **Compatibility**
ESBO has excellent compatibility with PVC.ESBO is compatible with PVC. When added to PVC, it can evenly disperse within the PVC matrix.When added to PVC it can disperse evenly within the matrix. This compatibility is due to the similar polarities of ESBO and PVC.This compatibility is a result of the similar polarities between ESBO and PVC. The long - chain fatty acid groups in ESBO can interact with the PVC chains through van der Waals forces, allowing for a homogeneous mixture.The van der Waals forces can allow the long-chain fatty acid groups of ESBO to interact with PVC chains, allowing a homogenous mixture.
2. **Plasticizing Effect**
ESBO acts as a plasticizer by reducing the intermolecular forces between PVC chains.ESBO reduces the intermolecular forces that exist between PVC chains. PVC is a relatively rigid polymer due to the strong intermolecular attractions between its chains.PVC is a rigid polymer because of the strong intermolecular attraction between its chains. ESBO molecules insert themselves between the PVC chains, separating them and enabling the chains to move more freely.ESBO molecules insert between the PVC chain, separating them to allow the chains to move freely. As a result, the PVC becomes more flexible, with improved processability during manufacturing.The PVC becomes more flexible and easier to process during manufacturing. It can be easily extruded, molded, or calendered into various products such as pipes, films, and coatings.It can be easily extruded or calendered to create various products, such as pipes, films and coatings.
3. **Benefits over Other Plasticizers**Benefits of Other Plasticizers
One of the major advantages of ESBO as a PVC plasticizer is its low toxicity.ESBO's low toxicity is one of its major advantages as a PVC Plasticizer. In applications where PVC products come into contact with food, medical devices, or the environment, the use of non - toxic plasticizers is crucial.Non-toxic plasticizers are essential in applications where PVC products will come into contact with medical devices, food, or the environment. ESBO meets these requirements, making it a preferred choice.ESBO is a good choice because it meets these requirements. Additionally, it has good heat and light stability, which helps to prevent the degradation of PVC products over time, maintaining their physical and mechanical properties.It also has good heat and lighting stability, which helps prevent degradation of PVC over time.

**III. Boiling Point of Epoxidized Soybean Oil**Boiling point of Epoxidized soybean oil**

The boiling point of epoxidized soybean oil is relatively high.The boiling point of soybean oil epoxidized is relatively high. Due to its complex molecular structure, which consists of large triglyceride - based molecules with added epoxy groups, ESBO has a boiling point in the range of approximately 280 - 310 degC.ESBO's boiling point is in the range 280 - 310 degrees C due to its complex molecular composition, which consists primarily of large triglyceride-based molecules with epoxy groups added. This high boiling point is beneficial in PVC applications.This high boiling temperature is advantageous in PVC applications. It means that ESBO has low volatility during the processing of PVC at elevated temperatures.This means that ESBO is less volatile when processed with PVC at high temperatures. During extrusion or injection molding of PVC, the high - temperature environment would cause low - boiling - point plasticizers to evaporate, leading to problems such as reduced plasticizing efficiency, product shrinkage, and the release of harmful fumes.The high-temperature environment during extrusion or injecting PVC would cause low-boiling-point plasticizers to vaporize, causing problems such as reduced plasticizing effectiveness, product shrinkage and the release harmful fumes. The high boiling point of ESBO ensures its long - term effectiveness as a plasticizer in PVC products, even under conditions of repeated heating and use.The high boiling point ensures that ESBO will remain effective as a PVC plasticizer even after repeated heating and usage.
