Anhydrous polymeric zinc(II) octanoate

Abstract

The structure of the title compound, poly­[zinc(II)‐bis(μ‐octanoato‐O:O′)], [Zn(C8H15O2)2]n, consists of polymeric sheets parallel to (100) in which tetrahedrally coordinated Zn2+ cations are connected by carboxyl­ate bridges in a syn–anti arrangement.

Conservation Issues in Several Twentieth-Century Canadian Oil Paintings: The Role of Zinc Carboxylate Reaction Products

“…The crystal structures of zinc aliphatic carboxylate salts of various chain lengths have been determined, either from single crystal studies or powder diffraction data (Lacouture et al 2000;Peultier et al 1999;Mesbah et al 2006Mesbah et al , 2007. In all cases, the zinc is bonded to the carboxylate groups through a bidentate bridging structure.…”

Isopropyl Octanoate Synthesis Catalyzed by Layered Zinc n-Octanoate

“…19,20 A basal distance of 20.83 Å was obtained (see Figure S1 and Table S1 in Supplementary Information), in perfect agreement with the literature. 18 The structuring of the layer occurs with the coordination of carboxylate groups to zinc, a fact that can be confirmed by analysis of the infrared spectrum from the compound, where there is a predominance of vibrational modes characteristic of the organic part of the structure of octanoic acid salts ( Figure 1B).…”

“…In the present TGA curve, the results were compatible with the ideal formula for zinc octanoate (Zn[C 7 H 15 COO] 2 ), where the observed ZnO percentage was 23.92%, consistent with the theoretical percentage of the proposed formula (23.13%). 18 …”

“…All diffraction peaks were indexed in accordance with the literature. 18 To calculate the basal cell parameters of zinc octanoate while avoiding errors attributed to the sample displacement from the center of the diffraction goniometer and larger errors at peaks positioned at lower diffraction angles, the reported procedure was used. 19,20 A basal distance of 20.83 Å was obtained (see Figure S1 and Table S1 in Supplementary Information), in perfect agreement with the literature.…”

Biodiesel: Raw Materials, Production Technologies and Fuel Properties

“…Existem relatos na literatura de que óxidos, HDLs ou HSLs na presença de ácidos carboxílicos geram carboxilatos lamelares que podem ser recuperados após o término da reação (o mesmo se aplica a óleos ácidos), sendo esses últimos, produzidos in situ, os verdadeiros responsáveis pela atividade catalítica observada. 86 90,91 Para que se possa fazer uma análise completa dos HDLs ou HSLs e seus derivados obtidos por calcinação, é necessária uma caracterização completa desses materiais após o uso, pois somente desta forma se pode afirmar ou não se o catalisador é regenerado intacto após o uso ou transformado in situ em outra forma de alta atividade catalítica.…”
