EPA Vapor Phase EPA Vapor Phase Library Listing – 3,300 spectra This library provides a focused collection of gas phase spectra of interest in environmental monitoring. It contains materials selected for inclusion by the US Environmental Protection Agency (EPA). The EPA Vapor Phase Library was acquired by the Environmental Protection Agency (EPA) in the late 1970s and early 1980s. The collection of 3,300 gas phase spectra was collected with a heated gas cell. The library includes the IUPAC (International Union of Pure and Applied Chemistry) chemical name and the WLN (Wiswesser Line-formula Chemical Notation) code.

  • Retention Indices for Frequently Reported Compounds of Plant Essential Oils
    Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

  • Visible-Light-Driven Photooxidation of Alcohols Using Surface-Doped Graphitic Carbon Nitride
    Electronic Supplementary Material (ESI) for Green Chemistry. This journal is © The Royal Society of Chemistry 2017 Visible-Light-Driven Photooxidation of alcohols using surface-doped graphitic carbon nitride Wuyuan Zhang, Anna Bariotaki, Ioulia Smonou, and Frank Hollmann* Material and Methods Materials Unless stated otherwise all chemicals were purchased from Sigma-Aldrich, Fluka, Acros or Alfa-Aesar with the highest purity available and used without further treatment. Synthesis of g-C3N4 and carbon nanodots doped (CD-C3N4) The g-C3N4 was synthesized via the simple calcination (Carbolite furnace; CWF 12/5, 2400 W) of urea (10.0 g) at 600 °C for 4 h (5 °C/min), a yellowish powder was obtained after the cooling to room temperature.1 The carbon nanodots were synthesized via the thermal decomposition of sucrose with slight modification.2 Briefly, 0.75 g of sucrose was dissolved in 30 mL of MilliQ water and stirred at room temperature for 0.5 h. The solution was transferred into a 45 mL Teflon-lined stainless steel autoclave reactor, and heated at 180 °C for 5 h (10 °C/min). After cooling the reactor to room temperature, a brown mixture was obtained. The mixture was centrifuged (8000 rpm for 20 min), and the pellet was washed with water (3×) and freeze-dried. 3 In order to deposit carbon nanodots to the surface of g-C3N4, Liu et al’s procedures were adopted. Firstly, a stock solution of carbon nanodots (1 mg in 25mL water) was prepared. 15.0 mL of this stock solution was mixed with 15.0 mL of NH4OH (28 %) and sealed in a 45 mL Teflon-lined autoclave reactor.

K. Dangarh Asstt. Prof. of Chemistry, Govt. P. G. College, Neemuch, M.P. ABSTRACT Oxidation of 4-Methoxybenzyl alcohol by different Cr (VI) oxidants [PDC and PCC] has been studied in acetic acid-H2O medium in the presence of PTSA spectrophotometrically. The reactions are found first order with respect to both the oxidants, [H+], and [substrate].Michaelis-Menten type kinetics is observed. The reaction rate decreases with increasing volume percentage of acetic acid in reaction mixture. The reaction was studied at different temperature [298-318 K] and activation parameters were computed. The oxidation product was identified as Cr (III) and corresponding aldehyde. The oxidation rate order was found with respect to the oxidants are: PCC > PDC KEYWORDS Oxidation, 4-Methoxybenzyl alcohol, PTSA, PCC and PDC. 1.

The carboxylic acids not only form an important class of organic compounds but are also the parent compounds of a large group of compounds called the functional derivatives of carboxylic acids which can be further classified as acid halides, acid anhydrides, acid .amides and esters. These classes of compounds \kill be discussed in Unit 17. Carboxylic acids also play an important role in various biological processes. In Unit 16, you will study about some such acids ..Besides carboxylic acids, there is another important class of organic acids, called sulphonic adds. The sulphonic acids are the compounds which contain a S03H group, called the sulphonic acid soup. Sulphonic acids are organic acids related to sulphuric acid. Sulphonic acids and carboxylic acids are closely related in their chemistry. Therefore, in this unit, we will first study the chemistry of carboxylic acids and then that of the sulphonic acids.

Except for formic acid, normal SCFAs with 2 to 8 carbons increased the OF in 6 rat RBCs with increasing number of hydrocarbons in a dose-dependent manner. 7 Replacement of the carboxylic group with sulfonic group inhibited, but did not abolish, 8 the SCFA-mediated increase in OF.

  • Fatty Acid Composition of Milk Fat in Milk of Tzigay Sheep and Their F2 Cross-Breeds with Chios
    Biotechnology in Animal Husbandry 31 (1), p 45-53 , 2015 ISSN 1450-9156 Publisher: Institute for Animal Husbandry, Belgrade-Zemun UDC 637.043:637.12'632 DOI: 10.2298/ BAH1501045G FATTY ACID COMPOSITION OF MILK FAT IN MILK OF TZIGAY SHEEP AND THEIR F2 CROSS-BREEDS WITH CHIOS G. Gerchev1, N. Naydenova2, S. Slavkova1, G. Mihaylova2 1Research Institute of Mountain Stockbreeding and Agriculture, 281 Vasil Levski Str., 5600, Troyan, Bulgaria 2Agrarian Faculty of Thracian University, Students’ campus, 6000, Stara Zagora, Bulgaria Corresponding author: [email protected] Original scientific paper Abstract: The study was conducted on aggregate milk samples, which were taken every month during the milking period from Tzigay sheep and their F2 cross-breeds of Chios, raised in the conditions of the Central Balkan Mountain. The fat extraction of milk samples was done by the Rose-Gottlieb method. Fatty acid composition was determined on a gas chromatograph with flame ionization detector and capillary column. The aim of the study was to follow the changes in the composition of fatty acids in the milk fat of milk of Tzigay sheep and their F2 cross-breeds. The saturated fatty acids in milk of the two groups had high values during both consecutive years, as they varied from 67.05% in milk of Tzigay sheep in the second lactation up to 70.87% at their F2 cross-breeds. The content of myristic acid was correspondingly 8.22-8.88% at Tzigay sheep and 8.45-8.74% at their F2 cross-breeds. The total amount of polyunsaturated fatty acids in the examined milk for the two types of sheep was comparatively low with near concentrations (4.39-5.20%) in the period of the two years.
