Voltammetric study of a sulfur contaminant of aviation biokerosene
(2020-08-01)
Butanethiol is a contaminant of aviation biokerosene, and its monitoring is of great importance to evaluate the quality of this biofuel. In this work, the elucidation of the electrochemical behavior of butanethiol was ...
In situ generation of n-butanethiol and its reaction with electron-deficient olefines
(TAYLOR & FRANCIS INC, 2008)
n-Butanethiol is generated in situ by sequential addition of n-butyllithium and water to elemental sulfur. The n-butanethiol formed was reacted with electron-deficient olefines to give Michael-type addition products in ...
Molecularly imprinted electrochemical sensor for monitoring mercaptan sulfur in aviation biofuel
(2022-01-01)
This work reports the development and application of a molecularly imprinted electrochemical sensor based on the electropolymerization of pyrrole film on glassy carbon electrode for monitoring mercaptan sulfur in aviation ...
Gas-phase degradation of 2-butanethiol initiated by OH radicals and Cl atoms: Kinetics, product yields and mechanism at 298 K and atmospheric pressure
(Royal Society of Chemistry, 2019-07)
Relative rate coefficients and product distribution of the reaction of 2-butanethiol (2butSH) with OH radicals and Cl atoms were obtained at atmospheric pressure and 298 K. The experiments were performed in a 480 L ...
Ca(2+)-mediated thiolysis of peptide-resin linkage as an option for preparing protected peptide thioesters
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A mild new procedure for preparing protected peptide thioesters, based oil Ca(2+)-assisted thiolysis of peptide-Kaiser oxime resin (KOR) linkage, is described. Ac-Ile-Ser(Bzl)-Asp(OcHx)-SR (Ac: acetyl; Bzl: benzyl; cHx: ...
Desenvolvimento de eletrodos modificados para determinação de compostos sulfurados em gasolina
(Universidade Estadual Paulista (Unesp), 2008-06-30)
Os compostos sulfurados no petróleo têm causado diversos problemas como os correlacionados à corrosão de equipamentos, envenenamento de catalisadores em processo de refino, qualidade dos produtos, além de liberação de gases ...
Hydrocarbon chain length induces surface structure transitions in alkanethiolate-Au adatom self-assembled monolayers on Au(111)
(American Chemical Society, 2013-01)
A detailed density functional calculation (DFT) study including van der Waals (vdW) dispersion forces of different adatom-containing models (RS−Auad−SR) at saturation coverage for methanethiol (MT), butanethiol (BT), and ...
An electrochemical gas sensor based on paper supported room temperature ionic liquids
(ROYAL SOC CHEMISTRYCAMBRIDGE, 2012)
A sensitive and fast-responding membrane-free amperometric gas sensor is described, consisting of a small filter paper foil soaked with a room temperature ionic liquid (RTIL), upon which three electrodes are screen printed ...
