1H,1H,2H,2H-Perfluorohexyl iodide synthesis
- Product Name:1H,1H,2H,2H-Perfluorohexyl iodide
- CAS Number:2043-55-2
- Molecular formula:C6H4F9I
- Molecular Weight:373.99
Yield:2043-55-2 85.3 kg
Reaction Conditions:
with 2,2'-azobis(isobutyronitrile) in isopropyl alcohol at 60 - 70; under 3375.34 Torr; for 3.5 h;Large scale;Green chemistry;Solvent;Temperature;Pressure;
Steps:
1.1; 1; 3.1; 5 Example 3:
(1) In a 100 liter pressure stainless steel reaction kettle, first add 500 g of azobisisovaleronitrile, and then vacuum inhale 80 kg of perfluoroiodobutane 80 kg and 16 kg of isopropyl alcohol, and stir to raise the temperature to 60 ° C. , slowly introduce ethylene to a pressure of 0.45MPa, holdingContinued temperature 65~70 °C reaction for 3.5 hours, the pressure no longer has a significant drop. The heating was removed, and the discharge was followed by distillation to remove isopropanol to obtain 85.3 kg of a 99% purity: C4F9CH2CH2I.
