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

  1. Make sure all valves are closed
  2. Make sure the power is turned off
  3. Connect the reagent valve to the reactor
  4. Reaction nb 1: Put the reagents amount needed in the reactor (amount of reagents: 4.88 kg sodium bicarbonate, 74.4L vinegar)
  5. Reaction nb 2: Put the new reagents amount needed in the reactor (amount o reagents: 3.77 L acetyl chlorie, 5Toluene-Solvent)
  6. 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.
