acetate

(ăs`ĭtāt'), one of the most important forms of artificial cellulose-based fibers; the ester of acetic acid. The first patents for the production of fibers from cellulose acetate appeared at the beginning of the 20th cent. During World War I, production of acetylcellulose began on an industrial scale for military applications. Acetate fibers are basically delivered in the form of a continuous textile yarn. Their principal use is in the production of widely used consumer goods, such as men's shirts, women's blouses, underwear, ties, bathing suits, jersey jackets and sweaters, suit fabrics, coats, and sports clothing.

acetate

[′as·ə‚tāt]
(organic chemistry)
One of two species derived from acetic acid, CH3COOH; one type is the acetate ion, CH3COO-; the second type is a compound whose structure contains the acetate ion, such as ethyl acetate.
(textiles)
The official name for the textile fiber produced from partially hydrolyzed cellulose acetate. Formerly known as acetate rayon.

acetate

1. any salt or ester of acetic acid, containing the monovalent ion CH3COO-- or the group CH3COO-
2. consisting of, containing, or concerned with the group CH3COO-
4. a sound recording disc composed of an acetate lacquer coating on an aluminium or plastic base: used for demonstration or other short-term purposes

Figure 3 shows that when acetate ions were replaced by m-HCn ions in ZC-m-HCn, the broad peak (FWHM = 359 [cm.sup.-1)] centered at 3450 [cm.sup.-1] in ZC-Ac was replaced by 2 sharp peaks, a strong peak at 3513 [cm.sup.-1] (FWHM = 14.8 [cm.sup.-1]) and a weak peak at 3574 [cm.sup.-1] (FWHM = 16.3 [cm.sup.-1]).
The molecular ion peaks for Curcumin-Cu(II) complex and Curcumin-Zn(II) complexes were positioned at 508.06 and 509.06 mass units, respectively, in the ESI-MS spectra (see Supplementary Data in Supplementary Material available online at http://dx.doi.org/10.1155/2014/325873) indicating that the acetate ions are one of the additional ligands rather than the hydroxyl group in the ML type complexes.
The cadmium in the molecular structure is a six-coordinate Cd[S.sub.2][O.sub.4] form in which the Cd ion is coordinated to two monodentate diethylthioureas and two chelating acetate ions. The coordination polyhedral around Cd(II) is a distorted octahedron which might be due to the small bite angles of the acetate ions: O(2)-Cd(1)-O(1) [54.51(6)[degrees]] and O(4)-Cd(1)-O(3) [54.20(6)].
