Diisooctyl ester and di-n-octyl ester are both octanoic acid ester compounds with slightly different chemical structures, so they may also exhibit different performance in some applications. The molecular formula of diisooctyl ester is C10H20O2, with a structural formula of CH3CH2CH3CH2COOCH3CH2CH3COOCH3. The molecular formula of diisooctyl ester is C10H20O2, with a structural formula of CH3CH24COOCH24

Firstly, from a chemical structure perspective, the main difference between diisooctyl ester and di-n-octyl ester is that they are respectively prepared by the reaction of isooctanol and n-octanol with octanoic acid. The alcohol group of diisooctyl ester is isooctanol, while the alcohol group of diisooctyl ester is n-octanol, which is also the origin of their names. Therefore, diisooctyl and di (n-octyl) esters may differ in certain properties

In terms of physical properties, there are also some differences between diisooctyl and di-n-octyl. For example, in terms of density, the density of diisooctyl ester is slightly lower than that of di-n-octyl ester; In terms of viscosity, the viscosity of diisooctyl ester is also slightly lower than that of di-n-octyl ester. These small differences may have an impact on their industrial production and application

In addition, there are differences in the application fields between diisooctyl and di-n-octyl esters. Diisooctyl ester is commonly used in fields such as inks, coatings, adhesives, etc. Its performance is stable, low volatility, and good weather resistance, so it is widely used in these fields. Dioctyl ester is often used as a solvent and diluent, and is also commonly found in products such as coatings and inks. Due to the strong volatility of di (n-octyl) ester, it poses certain risks to human health. Therefore, safety precautions should be taken during use

Overall, there are some differences in chemical structure, physical properties, and application fields between diisooctyl ester and di-n-octyl ester. Distinguishing their differences is crucial for the correct selection and use of these two substances. Therefore, we need to have a deep understanding of their characteristics and make reasonable choices based on their needs to ensure the safety and stability of production and use processes.
