Soaps and detergents info Chemical Man

Soaps and detergents are widely used as cleaning agents. Chemically soaps and detergentsare quite different from each other. The common feature of soaps and detergents is thatwhen dissolved in water the molecules of soap and detergent tend to concentrate at thesurface of the solution or at interface. Therefore, the surface tension of the solution isreduced, it causes foaming of the solution.
Soaps and detergents lower the surface tension of the solution. Such substances are calledsurface-active  agents  or  surfactants.To sum up, soaps and detergents:

petrochemicals produced from ethylene are info Chemical Man

Ethylene is obtained by pyrolysis of natural gas or from naphtha by cracking. Ethylene isan unsaturated hydrocarbon and has a carbon-carbon double bond. Therefore, ethylene isvery reactive and can be converted to a variety of petrochemicals and useful end products.

The major petrochemicals produced from ethylene are :

1. Ethyl alcohol
2. Ethylene oxide
3. Ethylene glycol
4. Dichloroethane
5. Vinyl chloride
6. Polyethylene
7. Ethyl benzene

1.  Ethyl Alcohol
