Pilot Plant test specification
Pre-Starting
Please read these instructions thoroughly. This will make sure you obtain full safe use, Keep this instruction manual in a handy place for future reference.
Prepare the reactor
- Make sure all valves are closed
- Make sure the power is turned off
- Connect the reagent valve to the reactor
- Reaction nb 1: Put the reagents amount needed in the reactor (amount of reagents: 4.88 kg sodium bicarbonate, 74.4L vinegar)
- Reaction nb 2: Put the new reagents amount needed in the reactor (amount o reagents: 3.77 L acetyl chlorie, 5L Toluene-Solvent)
- Closed the valve for reagent filling.
Safety precaution
-The hot water (+100 °c) could suffer some burns (tank number 1 = Reactor)
-Toluene: Sweet aroma, hidden dangers - inhalation, skin, and fire risks; long-term impacts on organs, development, and nervous system.
-Acetyl chloride: corrosive, flammable, explosive, lung irritant, potential carcinogen.
-Acetic anhydride: highly corrosive, burns eyes and skin, inhaling damages lungs, potential carcinogen, flammable, and reacts violently with many substances.
(Wear protective gloves/protective clothing/eye protection/face protection).
Acetic Anhydride Production operation method
1-Ensure all sanitary connections
2-Put the dangerous reagents in the "reagents tanks" (tank A= Acetyl chloride and tank B= Acetone)
3-Put the reagents in the reactor (vinegar and sodium bicarbonate)
3.1-Reaction 1: (vinegar or acetic acid 5%, sodium bicarbonate )
3.2-Reaction 2: "solvent : toluene", sodium acetate and Acetyl chloride)
4-Plug the control system
5-check the control system if it's works properly
6-Operate to boiling up the water (+100°c) in the "Jacket Reactor"
7-Operate the mixer to mix the reagents in the "Reactor"
8-Operate the reagents tanks (tank A and tank B) to transfer the reagents (from tank A and tank B to the "Reactor")
9-Operate to warming the water (50-80°c) in the "Jacket Reactor"
10-Operate to circling the water in the condenser
11-After finishing, Operate the pipe to close.
