Raw data of "Experimental data for green synthesis of Zn-abietate complex from natural resin" Data article
Description
This data is associated with the work “Experimental data for green synthesis of Zn-abietate complex from natural resin”. The characterization data of the Zn-abietate complex obtained from Pinus elliottii resin and their reactional intermediary (Na-abietate) are reported. The Na-abietate was prepared with purified Pinus resin and sodium hydroxide (≥ 99%) in a stoichiometric ratio of 1:1. For the Zn-abietate synthesis was used ZnSO4 and Na-abietate solutions were at mild temperature and stirring without using organic solvents to ensuring the green character of the synthesis. The XPS spectra were analysed using the CASA-XPS software. X-ray photoelectron spectroscopy (XPS) analysis of the Na-abietate salt confirms the presence of carbonyl groups, carbon-oxygen atoms simple bonds (O-C/O=C), and carboxylate groups oxygen atoms (O-C=O). Analysis of the Zn LMM Auger, for the Zn-abietate complex, indicates the presence of zinc atoms with oxidation state Zn2+, this is supported by the distance between Zn 2p3/2 and 1p1/2 in the XPS spectrum. The energy-dispersive X-ray spectroscopy (EDS) analysis was performed in quadruplicate. The elements can be identified by specific peaks labelled in the raw data. In the Zn-abietate sample was detectable contamination sodium due to the Na-abietate formed in the first stage of synthesis. For the Na-abietate no contaminants were identified by this technique due to the low sensitivity to surface contamination of this method.
