Gas production reaction (2)

Case 3

According to the literature, a researcher responded as follows:

Reactants and solvents: 500g ethyl chloropropionate , 450g TMSC1, 200g sodium sand, 3L ether

First, we must make various sodium sands

Reason analysis: ①This is a gas production reaction, the gas produced could not be exported in time, and no measures were taken to dilute the flammable and explosive gas; ②The reaction failed to control, resulting in the accumulation of latent heat of the reaction and flushing occurred: ③Reaction flask If it is too small, the effective space left is too small and does not meet the safety requirements; ④When a fire occurs, the fume hood door is pulled down by mistake, causing the fire extinguishing agent to fail to be sprayed, which is an ineffective fire extinguishing; ⑤If the exhaust is not turned off after a fire, the result is continuous supply Oxygen, the more the fire burns, making it extremely difficult to extinguish the fire; ⑥From the perspective of safety heat capacity, it is not appropriate to choose ether as the solvent for this reaction, because the boiling point of ether is low, the specific heat capacity is small, and the higher the temperature will cause flushing.

Case 4

A R&D staff made the following response:

The reaction has been tested several times before, and this time it is magnified 8 times

Reason analysis: the decomposition of hydrogen peroxide produces a large amount of oxygen
