EPA Method 8315A (SW-846): Determination of Carbonyl Compounds by High Performance Liquid Chromatography (HPLC)
METHOD 8315A DETERMINATION OF CARBONYL COMPOUNDS BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) 1.0 SCOPE AND APPLICATION 1.1 This method provides procedures for the determination of free carbonyl compounds in various matrices by derivatization with 2,4-dinitrophenylhydrazine (DNPH). The method utilizes high performance liquid chromatography (HPLC) with ultraviolet/visible (UV/vis) detection to identify and quantitate the target analytes. This method includes two procedures encompassing all aspects of the analysis (extraction to determination of concentration). Procedure 1 is appropriate for the analysis of aqueous, soil and waste samples and stack samples collected by Method 0011. Procedure 2 is appropriate for the analysis of indoor air samples collected by Method 0100. The list of target analytes differs by procedure.

The Summer Assignment Will Receive a GRADE on the First Day of Class – August 9
Bishop Moore AP Chemistry Summer Assignment June 2017 Future AP Chemistry Student, Welcome to AP Chemistry. In order to ensure the best start for everyone next fall, I have prepared a summer assignment that reviews basic chemistry concepts some of which you may have forgotten you learned. For those topics you need help with there are a multitude of tremendous chemistry resources available on the Internet. With access to hundreds of websites either in your home or at the local library, I am confident that you will have sufficient resources to prepare adequately for the fall semester. The reference text book as part of AP course is “Chemistry: The Central Science” by Brown LeMay 14th Edition for AP. Much of the material in this summer packet will be familiar to you. It will be important for everyone to come to class the first day prepared. While I review throughout the course, extensive remediation is not an option as we work towards our goal of being 100% prepared for the AP Exam in early May. There will be a test covering the basic concepts included in the summer packet during the first or second week of school. You may contact me by email: ([email protected]) this summer. I will do my best to answer your questions ASAP. I hope you are looking forward to an exciting year of chemistry. You are all certainly excellent students, and with plenty of motivation and hard work you should find AP Chemistry a successful and rewarding experience. Finally, I recommend that you spread out the summer assignment. -

Acetonitrile
Fact Sheet Acetonitrile What is Acetonitrile Acetonitrile is a toxic, colorless liquid with an ether-like odor and a sweet, burnt taste. It is an extremely dangerous substance and must be handled with caution as it can cause severe health effects and/or death. It is also known as cyanomethane, ethyl nitrile, ethanenitrile, methanecarbonitrile, acetronitrile cluster and methyl cyanide. Acetonitrile is easily ignited by heat, sparks or flames and gives off highly toxic hydrogen cyanide fumes when heated. It dissolves easily in water. It can react with water, steam or acids to produce flammable vapors that can from explosive mixtures when exposed to air. The vapors are heavier than air and can travel to low or confined areas. Containers of the liquid can explode when heated. Acetonitrile is used to make pharmaceuticals, perfumes, rubber products, pesticides, acrylic nail removers and batteries. It is also used to extract fatty acids from animal and vegetable oils. Before working with acetonitrile, employee training must be provided on safe handling and storage procedures. Pregnant women should avoid contact with acetonitrile. Exposure Exposure usually occurs in the industries where acetonitrile is produced or used. Though unlikely, the general population may be exposed by due to chemical spills, accidents or releases. It is also found in cigarette smoke and automobile exhaust. Acetonitrile changes to cyanide with the body. Route of exposure can occur by: . Breathing ─Inhalation of acetonitrile vapors can cause adverse health effects. Eating/Drinking ─Ingestion of acetonitrile is not a likely route of exposure due to its irritating effects. Skin/Eye Contact ─Acetonitrile vapors and liquids can be absorbed through the skin or eyes. -
An Extractive Distillation System for Benzene-Acetonitrile Separation Using Dimethyl Sulfoxide As an Entrainer Bloch Sohil Y
An Extractive Distillation System for Benzene-Acetonitrile Separation Using Dimethyl Sulfoxide as an Entrainer Bloch Sohil Y. & Mehulkumar Sutariya Sardar Vallabhbhai National Institute of Technology, Surat Email: [email protected] Unit System: Pressure-Kpa; Molar Flow-kg/hr; Other-SI Background Hydrocarbons like Acetonitrile and Benzene are important raw materials in the manufacturing of polymeric products and as a solvent. They often require high-purity Acetonitrile and Benzene. Acetonitrile is widely used mainly as a solvent in the purification of butadiene in refineries it is widely used in battery applications because of its relatively high dielectric constant and ability to dissolve electrolytes. For similar reasons it is a popular solvent in cyclic voltammetry. Acetonitrile plays a significant role as the dominant solvent used in the manufacture of DNA oligonucleotides from monomers.Industrially, it is used as a solvent for the manufacture of pharmaceuticals and photographic film.The mixer of Acetonitrile and Benzene can not be seperated out by the simple distillation column because of the less difference between their boiling point (near 1.5 K) and same boiling point behaviour of azeotrope. Extractive Distillation of Close Boiling Compounds Extractive distillation is the method of separating close boiling compounds from each other by carrying out the distillation in a multiple columns in the presence of an added liquid or liquid mixture.1 This Liquid or Liquid mixture is known as extractive agent or entrainer. The presence of the entrainer alter the volatility of compounds and thus the degree of separation is increase with the same numbers of plate. This entrainer must have high boiling point than the compounds which are going to separated. -
NMR Chemical Shifts of Common Laboratory Solvents As Trace Impurities
7512 J. Org. Chem. 1997, 62, 7512-7515 NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities Hugo E. Gottlieb,* Vadim Kotlyar, and Abraham Nudelman* Department of Chemistry, Bar-Ilan University, Ramat-Gan 52900, Israel Received June 27, 1997 In the course of the routine use of NMR as an aid for organic chemistry, a day-to-day problem is the identifica- tion of signals deriving from common contaminants (water, solvents, stabilizers, oils) in less-than-analyti- cally-pure samples. This data may be available in the literature, but the time involved in searching for it may be considerable. Another issue is the concentration dependence of chemical shifts (especially 1H); results obtained two or three decades ago usually refer to much Figure 1.

Also, any potential hydrogen- shifts of what are, in our experience, the most popular bond acceptor will tend to shift the water signal down- “extra peaks” in a variety of commonly used NMR field; this is particularly true for nonpolar solvents. In solvents, in the hope that this will be of assistance to contrast, in e.g. DMSO the water is already strongly the practicing chemist. hydrogen-bonded to the solvent, and solutes have only a negligible effect on its chemical shift. This is also true Experimental Section for D2O; the chemical shift of the residual HDO is very NMR spectra were taken in a Bruker DPX-300 instrument temperature-dependent (vide infra) but, maybe counter- (300.1 and 75.5 MHz for 1H and 13C, respectively).
