nitroglycerin production Separation:
After the reaction is complete, the mixture contains both nitroglycerin and unreacted acids. The nitroglycerin is typically separated using water, as it is less dense than the acid mixture and will float on top.

1. nitroglycerin production Washing:
   The nitroglycerin is washed with water to remove residual acids. This step is essential to stabilize the nitroglycerin and reduce its sensitivity.
