The production process of ethyl 2,3-dihydro-3-oxo-4-pyridazinecarboxylate is a multi-step process that involves several chemical reactions.
The starting material for the production of this compound is acetylene, which is a colorless gas with a distinct smell.
The production process can be broken down into several main stages, each of which involves a specific set of chemical reactions.

The first stage of the production process involves the reaction of acetylene with hydrogen chloride gas to form ethyl chloride.
This reaction is exothermic, meaning that it releases heat, and it is typically carried out in the presence of a solvent, such as water or ether.
The reaction is as follows:

C2H2 + HCl → C2H4 + H2O

The second stage of the production process involves the reaction of ethyl chloride with sodium hydroxide to form 2-chloroethanol.
This reaction is also exothermic and is typically carried out in the presence of a solvent, such as water or ether.
The reaction is as follows:

C2H4 + 2NaOH → 2NaCl + C2H5OH

The third stage of the production process involves the reaction of 2-chloroethanol with pyridine to form 2,3-dichloro-4-pyridinecarboxylic acid.
This reaction is carried out in the presence of a solvent, such as ether or benzene, and requires careful control of the reaction conditions, as the pyridine compound can be sensitive to air and moisture.
The reaction is as follows:

C2H5OH + C5H5N → C5H8Cl2N2 + H2O

The final stage of the production process involves the treatment of 2,3-dichloro-4-pyridinecarboxylic acid with sodium hydroxide to form ethyl 2,3-dihydro-3-oxo-4-pyridazinecarboxylate.
This reaction is exothermic and requires careful control of the reaction conditions, as the sodium hydroxide can cause the pyridine compound to degrade.
The reaction is as follows:

C5H8Cl2N2 + 2NaOH → C5H9NO3 + 2NaCl
