| Abstract: | Synthesis of diisooctyl phthalate (DOP) was presented by esterification of 2-ethyl octanol with phthalic anhydride under the catalyzation of stannous oxide, with no neutralization and no water wash to get the good quality of product. The best technical condition was as follows: stannous oxide (SnO) 0.8% (accounted from phthalic anhydride), reaction temperature 210-220℃, excess alcohol 18%, temperature of separating alcohol 160℃, pressure 20 kpa and active carbon 1‰. |
