dichloriden.

Brit.

/(ˌ)dʌɪˈklɔːrʌɪd/, U.S.

/daɪˈklɔˌraɪd/

Forms: see di- comb. form and chloride n.

Origin: Formed within English, by compounding. Etymons: di- comb. form, chloride n.

Etymology: < di- comb. form + chloride n. Compare bichloride n.

Chemistry.

1. A chloride containing two atoms of chlorine in its molecule or empirical formula. Cf. bichloride n., deuto-chloride at deuto- comb. form 1.In quot. 1812, introduced hypothetically in a discussion of Davy's system of nomenclature (cf. -ane suffix² 1). Otherwise sense 2 is earlier.

1812 Q. Rev. Sept. 76 We do not apprehend that the word ‘chlorid, following the analogy of oxyd’, (p. vii,) would have been a more ‘theoretical expression’ than the termination ane, and we might add to it, if necessary, dichlorid and trichlorid.

1868 H. Watts Dict. Chem. V. 135 The dichloride, RuCl², is produced, together with the trichloride, by igniting pulverised ruthenium in a stream of chlorine.

1906 H. J. H. Fenton Notes Qualitative Anal. (new ed.) 34 Distilled with dry potassium dichromate and concentrated H₂SO₄, chromyl dichloride (‘chlorochromic acid’) is obtained.

2009 Chicago Daily Herald (Nexis) 19 June 5 The mixture of trichloride and dichloride gave off a cloud of chlorine gas.

†2. A compound of chlorine with two atoms of another element (see di- comb. form 2a ⁋). Obsolete.
