Development of an extraction method for the determination of inorganic anions (chloride, sulfate and phosphate) in edible oils from different origins by ion chromatography
(2018)
The present work reports the development of ion chromatography conductivity based detection analytical method for the determination of some inorganic anions (chloride, sulfate and phosphate) in vegetable oils. The analytes ...
Microwave-Assisted Extraction of Chloride Followed by Ion Chromatography as an Alternative to the ASTM D6470 Method for the Determination of Crude Oil Salinity
(2020)
The presence of chloride in crude oil can result in a number of drawbacks, with technical and economic impacts on
the production of petroleum derivatives. For this reason, it must be carefully monitored in this kind of ...
A new method for the preparation of 1,3-dilithiopropyne: an efficient synthesis of homopropargyl alcohols
(2001)
Controlled dilithiation of propargyl bromide with two equivalents of n-butyllithium, in the presence of TMEDA, produces the operational equivalent of the dianion 1,3-dilithiopropyne. The latter reacts efficiently with ...
Aggregation pheromone of palmetto weevil, Rhynchophorus cruentatus (F.) (Coleoptera: Curculionidae)
(1994)
5-Methyl-4-octanol is the major aggregation pheromone of the palmetto weevil,Rhynchophorus cruentatus (F.). The pheromone (cruentol) was identified by coupled gas chromatographic-electroantennographic (GC-EAD) analysis of ...
Synthesis and Determination of Antitumor Activity of Jacaranone and Synthetic Analogs
(2018)
Natural product jacaranone, 1, and three analog derivatives were synthesized and their apoptotic and necrotic activity against four cancer cell lines was tested. One of these derivatives 7, was more active than the natural ...

Hydrochemistry of the surface waters at the Rincon River Basin, Osa Peninsula, Costa Rica
(2010-12)
The Rincon River Basin is characterized by steep and rugged topography with outcrops of recent sediments as well as igneous and sedimentary rocks. The area is mostly covered by forest (Tropical Wet Forest) and agricultural ...
Heterogeneous Water Oxidation: Surface Activity versus Amorphization Activation in Cobalt Phosphate Catalysts
(2015)
Is water oxidation catalyzed at the surface or within the bulk volume of solid oxide materials? This question is addressed for cobalt phosphate catalysts deposited on inert electrodes, namely crystallites of pakhomovskyite ...
