Cellulose may be quickly dissolved in a NaOH complex solvent (NaOH/urea/thiourea/H2O). A detailed investigation on the effects of solvent composition and temperature on cellulose solubility has been presented. Optical microscopy and wide-angle X-ray diffraction (WAXD) were used to study the process of dissolution. The highest solubility of cellulose was recorded in NaOH/urea/thiourea/H2O with a...

In this work the structural requirements of both urea and thiourea derivatives were evaluated for optimal antibacterial activity on Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli, using several organic compounds (VI-X) as chemical tools. In order to delineate the structural chemical requirements of studied compounds, the descriptors Log P, π MR and MV were calculated. The res...

1-Benzoylthioureas contain both carbonyl and thiocarbonyl functional groups and are of interest for their biological activity, metal coordination ability and involvement in hydrogen-bond formation. Two novel 1-benzoylthiourea derivatives, namely 1-benzoyl-3-(3,4-dimethoxyphenyl)thiourea, C16H16N2O3S, (I), and 1-benzoyl-3-(2-hydroxypropyl)thiourea, C11H14N2O2S, (II), have been synthesized and ch...

Control of the recombination process and improvement transport charge carriers could be achieved in photocatalysts by modifying catalytic support. In present study, our goal was to study effect nitrogen doping on graphene oxide sheets using sources such as urea, thiourea, or ethylenediamine produce GO-N supports which were used form ZnO/GO-N systems. The synthesis ZnO carried out through a hydr...

In this study, we proposed a new approach to assessing the processes of complexation in aqueous solutions using example interaction lead chloride with thiourea. The goal study was investigation “PbCl2-N2H4CS” and determination regions dominance thiourea coordination compounds, which are precursors during deposition sulphide films.Based on diagrams cross section lines equal fractions constructed...

Detection and removal of metal ion contaminants have attracted great interest due to the health risks that they represent for humans wildlife. Among proposed compounds developed these purposes, thiourea derivatives been shown as quite efficient chelating agents cations heavy components high-selectivity sensors. Understanding nature metal–ionophore activity is thus high relevance. We present a t...

A Michael-type reaction of β,γ-unsaturated α-keto ester and α-nitro ketone was established. With a thiourea catalyst derived from cinchona alkaloid, the reactions afford products in 47-94% yields with 68-96% ee.

2-Thiohydantoin derivatives are produced by heating a mixture of thiourea and an alpha-amino acid. The method described offers the advantages of simplicity, low cost, easy work-up and scalability.
