nitroxyln.

Brit.

/nʌɪˈtrɒksɪl/,

/nʌɪˈtrɒksʌɪl/, U.S.

/naɪˈtrɑks(ə)l/

Origin: Formed within English, by compounding. Etymons: nitro- comb. form, -oxyl comb. form.

Etymology: < nitro- comb. form + -oxyl comb. form. N.E.D. (1907) gives the pronunciation as (nəitrǫ·ksil) /naɪˈtrɒksɪl/.

Chemistry.

1. = nitryl n. Usually attributive. Now rare.
