An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
Sulfuryl fluoride (also spelled sulphuryl fluoride) is an inorganic compound with the formula SO 2 F 2.It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride, being resistant to hydrolysis even up to 150 °C. [3]
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
The sulfur dioxide then oxidized to sulfur trioxide using oxygen with vanadium(V) oxide as catalyst. 2 SO 2 + O 2 ⇌ 2 SO 3 (−198 kJ/mol) (reaction is reversible) The sulfur trioxide is hydrated into sulfuric acid H 2 SO 4: SO 3 + H 2 O → H 2 SO 4 (g) (−101 kJ/mol) The last step is the condensation of the sulfuric acid to liquid 97–98% ...
Stock indexes drifted to a mixed finish on Wall Street as some heavyweight technology and communications sector stocks offset gains elsewhere in the market. The S&P 500 slipped less than 0.1% ...
Lithium sulfide is prepared by treating lithium with sulfur. This reaction is conveniently conducted in anhydrous ammonia. [3] 2 Li + S → Li 2 S. The THF-soluble triethylborane adduct of lithium sulfide can be generated using superhydride. [4]
