SUMMARY

The discussion confirms that 1-butanol acts as a surfactant, effectively reducing the surface tension of water solutions by approximately 50% when present in concentrations below 3% by mass. This reduction in surface tension is attributed to the molecular structure of 1-butanol, which features a larger alkyl group compared to ethyl alcohol, making it a more potent surfactant. The findings highlight the effectiveness of 1-butanol in applications requiring surface tension reduction.

PREREQUISITES
  • Understanding of surfactant properties and functions

Is 1-butanol molecule a surfactant?
 
Chemistry news on Phys.org
Yes, a relatively small amount (less than 3% by mass) of 1-butanol in water solution decreases the surface tension to about half of the surface tension of pure water. Butanol is a stronger surfactant than ethyl alcohol because of it's larger alkyl group.
