Continued... Chemwatch: 1479-3 Page 3 of 11 Issue Date: 27/06/2017 Version No: 3.1.1.1 SODIUM DICHROMATE, DIHYDRATE Print Date: 29/07/2020 Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Continue flushing until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes. Transport to hospital or doctor without delay. Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. If skin or hair contact occurs: Immediately flush body and clothes with large amounts of water, using safety shower if available. Skin Contact Quickly remove all contaminated clothing, including footwear. Wash skin and hair with running water. Continue flushing with water until advised to stop by the Poisons Information Centre. Transport to hospital, or doctor. If fumes or combustion products are inhaled remove from contaminated area. Lay patient down. Keep warm and rested. Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. Inhalation Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. Transport to hospital, or doctor, without delay. For advice, contact a Poisons Information Centre or a doctor at once. Urgent hospital treatment is likely to be needed. If swallowed do NOT induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. Ingestion Observe the patient carefully. Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious. Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink. Transport to hospital or doctor without delay. Indication of any immediate medical attention and special treatment needed For acute or short term repeated exposures to dichromates and chromates: Absorption occurs from the alimentary tract and lungs. The kidney excretes about 60% of absorbed chromate within 8 hours of ingestion. Urinary excretion may take up to 14 days. Establish airway, breathing and circulation. Assist ventilation. Induce emesis with Ipecac Syrup if patient is not convulsing, in coma or obtunded and if the gag reflex is present. Otherwise use gastric lavage with endotracheal intubation. Fluid balance is critical. Peritoneal dialysis, haemodialysis or exchange transfusion may be effective although available data is limited. British Anti-Lewisite, ascorbic acid, folic acid and EDTA are probably not effective. There are no antidotes. Primary irritation, including chrome ulceration, may be treated with ointments comprising calcium-sodium-EDTA. This, together with the use of frequently renewed dressings, will ensure rapid healing of any ulcer which may develop. The mechanism of action involves the reduction of Cr (VI) to Cr(III) and subsequent chelation; the irritant effect of Cr(III)/ protein complexes is thus avoided. [ILO Encyclopedia] [Ellenhorn and Barceloux: Medical Toxicology] SECTION 5 FIREFIGHTING MEASURES Extinguishing media FOR SMALL FIRE: USE FLOODING QUANTITIES OF WATER. DO NOT use dry chemical, CO2, foam or halogenated-type extinguishers. FOR LARGE FIRE Flood fire area with water from a protected position Special hazards arising from the substrate or mixture Avoid storage with reducing agents. Fire Incompatibility Avoid any contamination of this material as it is very reactive and any contamination is potentially hazardous Advice for firefighters Alert Fire Brigade and tell them location and nature of hazard. May be violently or explosively reactive. Wear full body protective clothing with breathing apparatus. Prevent, by any means available, spillage from entering drains or water courses.

  • Working with Hazardous Chemicals
    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein.

  • Oxidation of 9-Fluorenol to 9-Fluorenone with Sodium Hypochlorite
    CHEM 2229 EXP 1: Oxidation of 9-Fluorenol to 9-Fluorenone with Sodium Hypochlorite Objective: In this experiment you will learn how to perform an oxidation reaction by oxidizing an alcohol (9- hydroxyfluorene) to a ketone (9-fluorenone) using sodium hypochlorite in an acidic environment; how to perform TLC to monitor a reaction; how to perform an extraction to isolate a product; and, how to verify purity of a product using TLC and melting point. * Chromatography is a useful method for separating components of a mixture of compounds based on their polarity. Thin layer chromatography is especially useful for determining the number of components in a mixture, the identity of the compounds, and the purity of a compound. **Solvent Extraction is also known as Liquid–liquid extraction (LLE) or partitioning. It is a method used to separate compounds based on their relative solubilities in two different immiscible liquids: usually the polar solvent water and a non-polar organic solvent. Immiscible means that the liquids do not mix and because of this form two distinct layers. ***The melting point (MP) is a physical property of a solid also used for the purpose of identification and purity determination.

    Chapter 3 Alcohols, Phenols, and Ethers Chapter 3 Alcohols, Phenols, and Ethers Chapter Objectives: • Learn to recognize the alcohol, phenol, and ether functional groups. • Learn the IUPAC system for naming alcohols, phenols, and ethers. • Learn the important physical properties of the alcohols, phenols, and ethers. • Learn the major chemical reaction of alcohols, and learn how to predict the products of dehydration and oxidation reactions. • Learn to recognize the thiol functional group. Mr. Kevin A. Boudreaux Angelo State University CHEM 2353 Fundamentals of Organic Chemistry Organic and Biochemistry for Today (Seager & Slabaugh) www.angelo.edu/faculty/kboudrea Introduction • In this chapter, we will start looking at organic molecules that incorporate C—O bonds. • Oxygen is in Group 6A of the periodic table, and in most of its compounds, contains two single bonds and two lone pairs (or one double bond and two lone pairs), and is sp3-hybridized with a bent molecular shape: O O •The alcohol, phenol, and ether functional groups are found in a number of important naturally occurring molecules: CH3CH2OH Ethanol OH CH3CH2OCH2CH3 Diethyl ether HO Menthol Cholesterol 2 1 Chapter 3 Alcohols, Phenols, and Ethers Alcohols 3 The Hydroxy (—OH) Functional Group •The hydroxyl group (—OH) is found in the alcohol and phenol functional groups. (Note: that’s not the same as hydroxide, OH-, which is ionic.) –in alcohols, a hydroxyl group is connected to a carbon atom. –in phenols, —OH is connected to a benzene ring. (The “parent” molecule of this class is also named phenol: PhOH or C6H5OH.) • When two carbon groups are connected by single bonds to an oxygen, this is classified as the ether functional group.
