IDENTIFICATION OF THE SUBSTANCE/MIXTURE AND OF THE COMPANY/UNDERTAKING Product Name Benzene-chromium(0) tricarbonyl 2.HAZARDS IDENTIFICATION Classification of the substance or mixture According to Regulation (EC) No1272/2008 Acute toxicity, Inhalation (Category 4) (Benzene)chromium tricarbonyl: Class: Small Molecule: Description (Benzene)chromium tricarbonyl is an organometallic compound of chromium. It is a useful catalyst for the hydrogenation of 1,3-dienes. Chromium is a chemical element which has the symbol Cr and atomic number 24. Reaction of exfoliated graphene and ( 6 benzene)Cr(CO) 3 In a typical reaction, ( 6 benzene)Cr(CO) 3 (36 mg, 0.17 mmol, FW = 214.4) was added to a suspension of exfoliated graphene (20 mg, 1.67 mmol of carbon) in THF (4 mL). The reaction mixture was stirred vigorously and refluxed at 72oC under argon, in the absence of light for 48 h.

If the R group is a vinyl or an aryl group, then the resulting carbene complex can react with an acetylene to form a new benzene ring to which is bonded the chromium tricarbonyl fragment. The two acetylene carbon atoms become part of the new ring, as does a carbon from one of the carbonyl ligands.

Project Iron and Steel Industry • EPCRA §313 requires manufacturing facilities included in SIC codes 20 through 39, which have ten or more employees, and which manufacture, process, or use specified chemicals in amounts greater than threshold quantities, to submit an annual toxic chemical release report. This written notification is called the Section 311 report. It is a one-time requirement and no specific form is needed. The company can either provide Material Safety Data Sheets for the chemicals or a list of chemicals. The annual Section 312 report is due by March 1 of each year. You must use a specific form (either a Tier I or Tier II form ...

Material Safety Data Sheets (MSDSs) and container labels are the main sources of chemical information. Wastes do not have MSDSs, but waste analysis, profiles, or manifests may have useful information. Review Appendix I to determine which inventoried items require submission of a Material Safety Data Sheet (MSDS).

Nov 01, 2007 · Not offering such specific health-hazard data in one's Material Safety Data Sheets means that necessary and adequate approaches are not being used. The absence of such information could prove to be indefensible in litigated cases. In the past, MSDS information has been based upon animal models and/or anecdotal occurrences. Introduction. In 1957, Fischer and Öfele published the preparation of tricarbonyl(η 6-benzene)chromium, which was the first arene tricarbonylchromium complex .Since then, a plethora of transition-metal complexes of arenes have been prepared, characterized and described in the literature.
