dioxan Chem.
(daɪˈɒksən)
Also dioxane (-eɪn).
[f. dioxy-, diox- + -an, -ane.]
Any of three liquids, C4H8O2, with a molecular structure consisting of a saturated ring of four carbon and two oxygen atoms; spec. 1, 4-dioxan, used in large quantities as a solvent. Also, any of the derivatives of these compounds.
| 1912 Jrnl. Chem. Soc. CI. 1803 This compound rapidly loses dioxan. 1946 Nature 19 Oct. 553/2 Alginic acid diacetate swells, but does not dissolve, in water,..dioxan and glacial acetic acid at ordinary temperatures. 1947 New Biol. III. 124 A solution of Formvar in 1–4 dioxane is commonly used. 1951 A. Grollman Pharmacol. & Therap. xii. 230 A number of dioxane derivatives have been..demonstrated to have an adrenolytic but not a sympatholytic action. 1960 E. H. Rodd Chem. Carbon Compounds IV. xvi. 1525 The 1:3-dioxans are methylene ethers of l:3-glycols and the 1:2-dioxans, of which little is known, are cyclic peroxides. 1965 Phillips & Williams Inorg. Chem. I. xv. 568 Advantages accrue on going to a solvent such as dioxan or dimethyl-formamide which have very low solvolysis constants. |
