PhD-thesis Wageningen University, Wageningen, The Netherlands – with references – with summaries in English and Dutch ISBN: 978-90-8504-787-2 Abstract Due to increasingly stringent environmental legislation car fuels have to be desulfurized to levels below 10 ppm in order to minimize negative effects on the environment as sulfur-containing emissions contribute to acid deposition (‘acid rain’) and to reduce the amount of particulates formed during the burning of the fuel. Moreover, low sulfur specifications are also needed to lengthen the lifetime of car exhaust catalysts.

  • Category Name C2-C4 Aliphatic Thiols Category Chemical Names
    SIAM 30, 20-22 April 2010 US/ICCA Category Name C2-C4 Aliphatic Thiols Category 1-Ethanethiol (CAS No. 75-08-1) Chemical Names 1-Propanethiol (CAS No.107-03-9) and CAS Nos. 1-Butanethiol (CAS No.109-79-5) 2-Propanethiol, 2-Methyl (CAS No. 75-66-1) H2 H2 C HS C C CH HS CH3 3 H2 1-Ethanethiol 1-Propanethiol (Ethyl Mercaptan) (n-Propyl Mercaptan) H H CH Structural Formulae 2 2 3 C C HS C CH 3 H3C SH H2 1-Butanethiol CH3 (n-Butyl Mercaptan) 2-Propanethiol, 2-Methyl (t-Butyl Mercaptan) SUMMARY CONCLUSIONS OF THE SIAR Category Rationale The C2-C4 Aliphatic Thiols contain a sulfhydryl (SH) functional group with a straight or branched aliphatic carbon chain that characterizes the category. The four aliphatic thiols are soluble in water and have reasonably comparable melting points, initial boiling points and vapor pressures, as well as very low and objectionable odor thresholds. The water solubility and narrow range of octanol-water partition coefficients (log Kow) for the three linear C2-C4 Aliphatic Thiols indicate that they will have similar environmental fate and are not expected to bioaccumulate in aquatic organisms. Ecotoxicity is similar for the three linear C2-C4 Aliphatic Thiols with data for fish, invertebrate and algae toxicity indicating a similar order of acute toxicity across the chemicals tested (ecotoxicity is less for t-butyl-mercaptan). ECOSAR has been used to address and support the data gaps for the linear category members. Environmental fate and toxicity data are available for the branched t-butyl mercaptan.

  • 8.6 Acidity of Alcohols and Thiols 355
    08_BRCLoudon_pgs5-1.qxd 12/8/08 11:05 AM Page 355 8.6 ACIDITY OF ALCOHOLS AND THIOLS 355 ural barrier to the passage of ions. However, the hydrocarbon surface of nonactin allows it to enter readily into, and pass through, membranes. Because nonactin binds and thus transports ions, the ion balance crucial to proper cell function is upset, and the cell dies. Ion Channels Ion channels, or “ion gates,” provide passageways for ions into and out of cells. (Recall that ions are not soluble in membrane phospholipids.) The flow of ions is essen- tial for the transmission of nerve impulses and for other biological processes. A typical chan- nel is a large protein molecule imbedded in a cell membrane. Through various mechanisms, ion channels can be opened or closed to regulate the concentration of ions in the interior of the cell. Ions do not diffuse passively through an open channel; rather, an open channel contains regions that bind a specific ion. Such an ion is bound specifically within the channel at one side of the membrane and is somehow expelled from the channel on the other side. Remark- ably, the structures of the ion-binding regions of these channels have much in common with the structures of ionophores such as nonactin. The first X-ray crystal structure of a potassium- ion channel was determined in 1998 by a team of scientists at Rockefeller University led by Prof. Roderick MacKinnon (b. 1956), who shared the 2003 Nobel Prize in Chemistry for this work. The interior of the channel contains binding sites for two potassium ions; these sites are oxygen-rich, much like the interior of nonactin.

  • Recent Developments on the Origin and Nature of Reductive Sulfurous Off-Odours in Wine
    fermentation Review Recent Developments on the Origin and Nature of Reductive Sulfurous Off-Odours in Wine Nikolaus Müller 1,* and Doris Rauhut 2 1 Silvanerweg 9, 55595 Wallhausen, Germany 2 Department of Microbiology and Biochemistry, Hochschule Geisenheim University, Von-Lade-Straße 1, 65366 Geisenheim, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49-6706-913103 Received: 9 July 2018; Accepted: 3 August 2018; Published: 8 August 2018 Abstract: Reductive sulfurous off-odors are still one of the main reasons for rejecting wines by consumers. In 2008 at the International Wine Challenge in London, approximately 6% of the more than 10,000 wines presented were described as faulty. Twenty-eight percent were described as faulty because they presented “reduced characters” similar to those presented by “cork taint” and in nearly the same portion. Reductive off-odors are caused by low volatile sulfurous compounds. Their origin may be traced back to the metabolism of the microorganisms (yeasts and lactic acid bacteria) involved in the fermentation steps during wine making, often followed by chemical conversions. The main source of volatile sulfur compounds (VSCs) are precursors from the sulfate assimilation pathway (SAP, sometimes named as the “sulfate reduction pathway” SRP), used by yeast to assimilate sulfur from the environment and incorporate it into the essential sulfur-containing amino acids methionine and cysteine. Reductive off-odors became of increasing interest within the last few years, and the method to remove them by treatment with copper (II) salts (sulfate or citrate) is more and more questioned: The effectiveness is doubted, and after prolonged bottle storage, they reappear quite often.

Corrosive properties of LPG and problems with their determination. The Archives of automotive Engineering – Archiwum Motoryzacji. 2016; 74(4): 7-17, http://dx.doi.org/10.14669/ AM.VOL74.ART1 CORROSIVE PROPERTIES OF LPG AND PROBLEMS WITH THEIR DETERMINATION PAWEŁ BUKREJEWSKI1, DOROTA WARDZIŃSKA2, MARTA SKOLNIAK3 Automotive Industry Institute (PIMOT) Summary The corrosiveness of gaseous fuels is a known and frequently encountered problem, but the methods employed to explore this issue not always lead to the obtaining of reliable results. This article presents results of interlaboratory comparisons carried out to verify the method of evaluation of the corrosiveness of liquefied petroleum gas (LPG) according to Standard PN-EN ISO 6251. The corrosiveness of LPG to copper was tested for four different samples of the LPG fuel. Keywords: LPG, coper corrosion, degree of corrosion 1. Introduction The liquefied hydrocarbon gas, referred to as LPG (liquefied petroleum gas), is the Poland’s most popular alternative fuel [3]. Both in the production process and during transport, this fuel is exposed to the impact of many unfavourable factors. The LPG quality is particu- larly jeopardized during the transhipment processes in transport, when this fuel may be exposed to the penetration of such substances as water and sulphur compounds into it. The contaminants present in LPG may cause corrosion of the structural materials being in contact with this fuel, e.g. fuel system components, gasholders, or transmission instal- lations. The solid products of corrosion processes are mechanical contaminants, which, having penetrated with the fuel into the gas feeding system of a vehicle, may cause dam- age to system components [1, 6].

The others are multi-starter consortia that include non-Saccharomyces/Saccharomyces mixtures or only non-Saccharomyces species. Several com- mercial yeasts have shown adequate biocompatibility with S. cerevisiae in mixed fermentations, allowing an increased contribution of metabolites of oenological interest, such as glycerol, esters, higher alcohols, acids, thiols, and terpenes, among others, in addition to a lower production of acetic acid, volatile phenols, biogenic amines, or urea. Multi-starter inoculations are also reviewed here, which show adequate biocompatibility and synergy between species. In certain cases, the aromatic profile of wines based on grape varieties considered neutral is improved. In addition, several yeasts show the capacity as biocontrollers against contaminating microorganisms. The studies conducted to Citation: Vejarano, R.; Gil-Calderón, A.
