Dioctyl DOA and dioctyl DOP are commonly used plastic softeners and are widely used in the plastics and rubber industries. Although they have similar chemical structures and properties, they differ in some ways. The chemical structures of

dioctyl DOA and DOP are slightly different. DOA refers to dicaprylamide, chemical formula C22H42O4, and DOP refers to dicaprylate, chemical formula C24H38O4. Due to the difference in chemical structure, dioctyl DOA and DOP may exhibit different properties in some applications. The melting points of

dioctyl DOA and DOP are also different. The melting point of DOA is between -68°C and -6°C, while the melting point of DOP is between -50°C and -10°C. This means that at different temperatures, DOA and DOP may have different plasticizing effects. Therefore, when selecting additives, it is necessary to determine which type of additives to use according to specific process conditions and requirements.

Furthermore, the solubility of DOA and DOP are not exactly the same. DOA has a low solubility in water, while DOP has a high solubility in water. This also reflects their differences in different applications. As needed, suitable additives can be selected to meet specific process requirements.

In addition, there is a difference in price between DOA and DOP. In general, the price of DOA is relatively low, while the price of DOP is relatively high. When choosing additives, cost is also one of the factors to consider.

To sum up, dioctyl DOA and DOP are commonly used plastic softeners, and there are some small differences in chemical structure, melting point, solubility and price. When selecting the right additives, it is necessary to consider the specific process conditions, requirements and cost factors to ensure the best plasticizing effect. I hope this article is helpful for you to understand the difference between DOA and DOP.
