General description

2-Ethylhexanoic acid (EHXA, 2-EHA) is an industrially important aliphatic carboxylic acid.[1] It is widely employed as a stabilizer[2] and a wood preservative.[2]
It has various industrial applications, such as:[3]
  • coolant in automotives
  • synthetic lubricant
  • wetting agent
  • co-solvent
  • drying of paints
  • defoaming agent in pesticides

Application

  • A review of the environmental fate and aquatic effects of a series of C4 and C8 oxo-process chemicals.: This review assesses the environmental impact of C4 and C8 oxo-process chemicals, including 2-Ethylhexanoic acid, detailing their degradation, persistence, and effects on aquatic ecosystems (Staples, 2001).

This study examines the ability of P450cam to catalyze the formation of 2-ethylhexanoic acid from 2-ethylhexanol relative to its activity on the natural substrate camphor. As is the case for camphor, the P450cam exhibits stereoselectivity for binding (R)- and (S)-2-ethylhexanol.
