  1. The research of the pour point depressant in the 10B preparation process Chen Yongpan

  2. Subject Origin The good point of acetone： 1.Higher Separation factor 2.More stable than anisole The weak point of acetone： Freezing point of complex compound close to normal temperature So acetone will be a good complex agent if we can solve the problem

  3. Subject Origin • Pour Point Depressant（PPD） • Allows diesel freezing point lower 15-30 ℃, to achieve the purpose of improving the low temperature flow of the diesel. • We could use an agent like PPD to reduce the freezing point of acetone·BF3

  4. The mechanism of PPD • 1. Nucleation theory • 2. Adsorption theory • 3. Eutectic theory • 4.Adsorption-eutectic theory • 5. Improve the solubility theory

  5. The require of acetone·BF3’s PPD • 1. stability • 2. withstand high temperature • 3. make the freezing point lower nearly 10 ℃

  6. Model building TANK transfer piping engine For diesel: Hightempureture TANK transfer piping and column Schizolysis column For acetone: Reaction happens

  7. Problems • 1. PPD usually is a macromolecular, and acetone·BF3is micromolecule, PPD may fail. • 2. The crystallize mechanism of acetone·BF3 is not clear. There are a lot of work to do if we want to find a new PPD.
