SULFUR TRIOXIDE -- Chemical Fact Sheet
OLEUM/SULFUR TRIOXIDE -- Chemical Fact Sheet 1 What is it? Oleum is a cloudy, gray, fuming, oily, corrosive liquid with a sharp, penetrating odor. When Oleum comes into contact with air following a spill, it releases Sulfur Trioxide. Sulfur Trioxide is a white gas having the appearance of fog. It also has a sharp, penetrating odor that is detectable at low concentrations. Because of the tendency to liberate Sulfur Trioxide on contact with air, Oleum is also known as “fuming Sulfuric Acid”. Where does it Oleum is made by dissolving Sulfur Trioxide into Sulfuric Acid. Sulfur come from? Trioxide is made from Sulfur Dioxide in the presence of a catalyst. What are the It is used in the oil refining process to make crude oil distillates into higher quality materials. common uses for it? Manufacture of soap Manufacture of high purity Sulfuric Acid for the electronic industry Manufacture of catalyst used in production of Sulfuric Acid. How is it Oleum is shipped by truck and pipeline. transported in CCC? How is it stored Oleum is stored in covered tanks. in CCC?

Source Test Method ST-20 SULFUR DIOXIDE, SULFUR TRIOXIDE
Source Test Method ST-20 SULFUR DIOXIDE, SULFUR TRIOXIDE, SULFURIC ACID MIST (Adopted January 20, 1982) REF: Regulations 6-320, 6-330, 9-1-302, 9-1-304 thru 310, 10-1-301, 12-6-301 1. APPLICABILITY 1.1 This method is used to quantify emissions of s ulfur dioxide, sulfur trioxide and sulfuric acid mist. It determines compliance with Regulations 6-320 and 6-330 for SULFUR TRIOXIDE and SULFURIC ACID MIST, and 9-1-302, 9- 1-304 thru 310 and 10-1-301 and 12-6-301 for SULFUR DIOXIDE. 1.2 This method, modified with a glass fiber disc filter as the back-up SO 3 filter, has been given alternate status by the EPA to EPA Method 8. It may be used to determine compliance with oxides of sulfur regulations under Regulation 9. 2. PRINCIPLE 2.1 Sulfuric acid mist, sulfur trioxide and sulfur dioxide are collected in a single extractive sampling train. Acid mist is trapped in a quartz wool plug in the sample probe and is subsequently analyzed with an acid-base titration. Sulfur trioxide is absorbed in an 80% isopropyl alcohol (IPA)/water solution with a quartz wool back-up filter and is analyzed using analytical procedure Lab-12. Sulfur dioxide is absorbed in an aqueous hydrogen peroxide solution and is analyzed using analytical procedure Lab-12. 3. RANGE 3.1 The minimum measurable concentration using this method listed below are: 3 3.1.1 Acid mist - 0.0002 gr/ft as H2SO4 3.1.2 Sulfur trioxide - 7 ppm 3.1.3 Sulfur dioxide - 7 ppm 3.2 The maximum measurable concentrations using this method listed below are: 3.2.1 Acid mist - undetermined 3.2.2 Sulfur trioxide - 350 ppm 3.2.3 Sulfur dioxide - 2.5 % 4. -

Wood Modified by Inorganic Salts: Mechanism and Properties
WOOD MODIFIED BY INORGANIC SALTS: MECHANISM AND PROPERTIES. I. WEATHERING RATE, WATER REPELLENCY, AND IIIMENSIONAL STABILITY OF WOOD MODIFIEID WITH CHROMIUM (111) NITRATE VERSUS CHROMIC ACID' R. S. Willianzs and W. C. Feisl Research Chemists Forest Products Lab~ratory,~Forest Service U.S. Department of Agriculture Madison, WI 53705 (Received October 1983) ABSTRACT Chromic acid treatment of wood improves surface characteristics. A simple dip or brush application of 5% aqueous chromic acid to a wood surface stops extractive staining, improves dimensional stability, retards weathering of unfinished wood, and prolongs the life of finishes. A better understanding of how chromic acid effects these improvements may facilitate the development of even better treatments. The improvements may be due to a combination offactors: oxidation ofwood by hexavalent chromium compounds, formation of coordination coml~lexeswith trivalent chromium, and the presence of insoluble chromium compounds at the surface. Most trivalent chromium compounds do not become fixed in wood (i.e., do not form water-insolublf: wood-chemical complexes). However, chromium (111) nitrate treatment of western redcedar (Thuja plicata), southern pine (Pinus sp.), and ponderosa pine (Pinus ponderosa) produced modified wood with properties similar to chromic acid-treated wood. Evaluation of the chromium (111) nitrate- and chromic acid-modified wood by leaching, Xenon arc- accelerated weathering, and swellometer experiments clearly demonstrated similar fixation, erosion, and water-repellent properties. Based on the results from chromium (111) nitrate-treated wood, fixation through coordination of trivalent chromium with wood hydroxyls an(5 formation of insoluble chromium appear to be the critical factors in improving the performance of the treated wood. -

Department of CMMUTtY The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 ABSTRACT A number of synthetic routes to silver(II) fluorosulfate, Ag(SC>3F)2, were systematically explored. The most suitable and versatile route was found to be the oxidation of silver metal by a solution of bisfluorosulfuryl peroxide, S20gF2, in fluorosulfuric acid, HSO^F, according to: HS03F Ag + S206F2 m- Ag (SC>3F) 2> Additional methods which were found to be suitable involved the oxidation of a wide variety of silver(I) compounds such as S F or the nsert:LOn of S0 Ag20 or AgSO^F by 2°6 2' i- 3 into AgF2. Structural conclusions on Ag(S03F)2 and the other compounds synthesized subsequently were based on the vibrational, elec• tronic and electron spin resonance spectra, as well as on magnetic susceptibility measurements made between 300 and 77 K. -
Chromium Compounds Hazard Summary
Chromium Compounds Hazard Summary Chromium occurs in the environment primarily in two valence states, trivalent chromium (Cr III) and hexavalent chromium (Cr VI). Exposure may occur from natural or industrial sources of chromium. Chromium III is much less toxic than chromium (VI). The respiratory tract is also the major target organ for chromium (III) toxicity, similar to chromium (VI). Chromium (III) is an essential element in humans. The body can detoxify some amount of chromium (VI) to chromium (III). The respiratory tract is the major target organ for chromium (VI) toxicity, for acute (short-term) and chronic (long-term) inhalation exposures. Shortness of breath, coughing, and wheezing were reported from a case of acute exposure to chromium (VI), while perforations and ulcerations of the septum, bronchitis, decreased pulmonary function, pneumonia, and other respiratory effects have been noted from chronic exposure. Human studies have clearly established that inhaled chromium (VI) is a human carcinogen, resulting in an increased risk of lung cancer. Animal studies have shown chromium (VI) to cause lung tumors via inhalation exposure. Please Note: The main sources of information for this fact sheet are EPA's Integrated Risk Information System (IRIS) (7), which contains information on inhalation chronic toxicity and the RfC and oral chronic toxicity and the RfD, and the carcinogenic effects of chromium including the unit cancer risk for inhalation exposure, EPA's Toxicological Review of Trivalent Chromium and Toxicological Review of Hexavalent Chromium (3), and the Agency for Toxic Substances and Disease Registry's (ATSDR's) Toxicological Profile for Chromium. (1) Uses The metal chromium is used mainly for making steel and other alloys. -

Why? When you began chemistry class this year, you probably already knew that the chemical formula for carbon dioxide was CO2. Today you will find out why CO2 is named that way. Naming chemical compounds correctly is of paramount importance. The slight difference between the names carbon monoxide (CO, a poisonous, deadly gas) and carbon dioxide (CO2, a greenhouse gas that we exhale when we breathe out) can be the difference between life and death! In this activity you will learn the naming system for molecular compounds.
