  • Specialized
: ciclohexilamina
  • The United States uses two to three million kilograms of cyclohexylamine (CHA) each year as a corrosion inhibitor in steam lines and boilers.

Examples

  • Investigators learned that the corrosion-inhibiting chemicals, cyclohexylamine and diethylaminoethanol (DEAE), were previously added to the boiler water above normal strength.

    Academic text (1993)
  • Some CHA loss is incurred during condensate deaeration because of the volatile nature of cyclohexylamine (15).

    Academic text (1993)
  • Large fluctuations of the cyclohexylamine concentration in steam, however, are known to result from the design of some steam systems (16).

    Academic text (1993)
  • A recent mammalian fertility study suggests that cyclohexylamine targets Sertoli cells in the testes (7).

    Academic text (1993)
  • It is possible to estimate the cyclohexylamine from the data presented in Table I using a simple material balance calculation, assuming no significant internal source of humidity, no internal CHA source, and no significant internal removal of CHA.

    Academic text (1993)
  • Cyclohexylamine (CHA) possesses a probable lethal human oral dose of 50 mg/kg.

    Academic text (1993)
  • Nurses experienced upper respiratory distress and burning eyes after the corrosion inhibitors cyclohexylamine and morpholine were added to boiler water used to humidify the wards.

    Academic text (1993)
  • A 44.2 percent aqueous mixture of cyclohexylamine was fed directly into the boiler water at a rate of approximately 0.45 kg per day by automatic doser.

Morphology

cyclohexylamine = cyclohexyl (opaque) = cyclohexyl + amine

The form is systematic chemical nomenclature ('cyclohexyl' + '-amine'), but the term denotes a specialized organic compound and its meaning is not derivable by an average B1 learner.

Etymology

Cyclohexylamine is made of simple parts you can remember: cyclo- means 'circle', hexyl means 'six', and amine comes from 'ammonia'. So the name describes a chemical with a six‑carbon ring attached to an ammonia-like group, which fits its modern use as a colorless liquid in industry.
