The Production Process of Ethotoin

Ethotoin is a chemical compound that is commonly used as a intermediate in the production of various pharmaceuticals and agrochemicals.
The production process of ethotoin involves several steps, which are described below in detail.

Step 1: Preparation of raw materials
The production of ethotoin begins with the preparation of raw materials.
The key raw material required for the production of ethotoin is aniline, which is a toxic liquid with a foul odor.
Aniline is a starting material for the production of several chemical compounds, including ethotoin.

Step 2: Diazotization
The next step in the production of ethotoin is diazotization.
In this step, aniline is treated with a mixture of nitric acid and hydrogen peroxide in the presence of a catalyst, such as iron or copper.
This reaction results in the formation of paranitroaniline, which is a yellowish-brown liquid.

Step 3: Reduction
The paranitroaniline obtained from the diazotization step is then reduced to form ethanol.
This reduction step is typically carried out using a reducing agent such as hydrogen in the presence of a catalyst, such as palladium or platinum.
The reduction reaction results in the formation of ethanol, which is a colorless liquid.

Step 4: Chlorination
The ethanol obtained from the reduction step is then subjected to chlorination.
In this step, the ethanol is treated with chlorine gas in the presence of a catalyst, such as aluminum chloride.
This reaction results in the formation of ethyl chloride, which is a colorless gas.

Step 5: Dehydrochlorination
The ethyl chloride obtained from the chlorination step is then treated with hydrogen gas in the presence of a catalyst, such as platinum or palladium.
This reaction results in the formation of ethanol, which is a colorless liquid.

Step 6: Reduction
The ethanol obtained from the dehydrochlorination step is then reduced to form ethotoin.
This reduction step is typically carried out using a reducing agent such as hydrogen in the presence of a catalyst
