bis(1-methylheptyl) phthalate - Physico-chemical Properties
| Molecular Formula | C24H38O4 |
| Molar Mass | 390.56 |
| Density | 1.0101 (rough estimate) |
| Boling Point | 435.74°C (rough estimate) |
| Storage Condition | -20°C |
| Refractive Index | 1.4460 (estimate) |
| Physical and Chemical Properties | Chemical properties pale yellow viscous liquid. Freezing point -60 ℃, boiling point 210 ℃(1.33kPa, accompanied by decomposition),190 ℃(0.133kPa), relative density 0.965(25/4 ℃), refractive index 1.480, flash point 201 ℃, soluble in most organic solvents and hydrocarbons, solubility in water at 25 ℃ <0.03%, solubility in water <0.15%. |
| Use | Use of PVC, nitrocellulose resin plasticizer. General performance similar to DOP, but plasticizing efficiency, oil resistance, resistance to gasoline extraction is low, heat resistance, light resistance, weather resistance is better. It is usually used as a substitute for DOP. The product is particularly suitable for plasticizing paste, viscosity stability. |

bis(1-methylheptyl) phthalate - Uses and synthesis methods
production method
From the esterification of phthalic anhydride and secondary octanol. Secondary octanol is a by-product of castor oil cracking to generate sebacic acid. It is esterified with phthalic anhydride under sulfuric acid catalysis, and then neutralized in sodium carbonate solution, reduced pressure rectification, and excess secondary octanol and octanone are recovered, Octene and other by-products, and finally the finished product is filtered by pressure.
