DDT (dichlorodiphenyltrichloroethane) is a synthetic insecticide that gained widespread use in the mid-20th century. The preparation of DDT involves several chemical reactions. Here's a simplified overview:
1. **Starting Materials:**
- Chloral (trichloroacetaldehyde)
- Aniline (phenylamine)
- Sulfuric acid
2. **Reaction Steps:**
- Chloral reacts with aniline in the presence of sulfuric acid to form DDT.
- The specific reactions involve the replacement of hydrogen atoms with chlorine atoms.
3. **Chemical Equations:**
- The reactions can be represented by chemical equations, but these are complex and involve multiple steps.
It's important to note that the synthesis of DDT has significant environmental and health concerns, leading to its ban or severe restrictions in many countries due to its persistence in the environment and harmful effects on wildlife and humans.
DDT is prepared by heating Chloral ( C 2 HCl 3 O ) and Chloro benzene ( c 6 H 5 Cl ) by heating in a ratio of in the presence of conc. Sulphuric acid ( H 2 SO ) 4 .
