Description

Cyclohexylamine is an organic compound, belonging to the aliphatic amine class. It is a colorless liquid, although like many amines, samples are often colored due to contaminants. It has a fishy odor and is miscible with water. Like other amines, it is a weak base, compared to strong bases such as NaOH, but it is a stronger base than its aromatic analog, aniline.
It is a useful intermediate in the production of many other organic compounds. It is a metabolite of cyclamate.

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

A 100% theoretical BOD was observed for 10 mg/l of cyclohexylamine in an acclimated sewage inoculum, plant sludge and river mud over a 14 day incubation period(1). The theoretical BOD of cyclohexylamine (50 mg/l) was 79%, 68 % and 0% in an acclimated sewage inoculum, plant sludge and river mud respectively over a 14 day incubation period(1). The theoretical BOD of cyclohexylamine (100 mg/l) was 79%, 0% and 0% in an acclimated sewage inoculum, plant sludge and river mud respectively over a 14 day incubation period(1). A 200 mg/l sample of cyclohexylamine could not be biodegraded by an activated sludge and was assumed to be toxic to the microflora(2). A theoretical oxygen demand between 25 and 45% was observed for cyclohexylamine in a Warburg apparatus during a 5 day incubation period(3).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated for cyclohexylamine(SRC), using a log Kow of 1.49(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of cyclohexylamine is estimated as 150(SRC), using a measured log Kow of 1.49(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that cyclohexylamine is expected to have very high mobility in soil. The pKa of cyclohexylamine is 10.6(4), indicating that the protonated form will be the predominant species in moist soils and cations are expected to adsorb strongly to soil surfaces.

12.5 Other adverse effects
