Fluoroantimonic acid (HSbF6) is formed by mixing HF and SbF5. It is 2×1019 times stronger than 100% sulfuric acid. Has a H0 value of -31.3 and dissolves glass. Rapidly decomposes in water, generating toxic vapors
Magnetic float with magnet indicates liquid level through guide rail flaps. Floats float on medium, magnetically rotating to show level position. One side is red, other side is white for intuitive reading
Petrochemicals are chemical products derived from petroleum through refining. Two main classes are olefins (ethylene, propylene) and aromatics (benzene, toluene). Olefins are produced by fluid catalytic cracking of petroleum fractions. Aromatics are produced through catalytic reforming of naphtha
Hydrogenation is the addition of hydrogen to compounds using catalysts. Process typically involves adding hydrogen pairs to alkenes. Requires catalysts like nickel, palladium or platinum for usable reactions. Hydrogenation reduces double and triple bonds in hydrocarbons
