“Sulfide” isn’t a thing without whatever it’s a sulfide of. Hydrogen sulfide is a toxic and terrible-smelling gas. Cadmium sulfide is a bright yellow solid. “Town gas” is typically a mix of carbon monoxide and hydrogen. LPG is also a mix, including propane, butane, and isobutane,...
Explain the method of preparing tert-butyl-chloride from isobutane involving a (Cl2) free radical. Is the cation in MnI3 manganese(II) or manganese(III)? Explain. Explain the origin of the difference between the ground state and excited state bond lengths for ...
Methane (CH4), ethane (C2H6), and propane (C3H8) have no isomers because their is only one way the carbons can hook together. Butane (C4H10) has two isomers (n-butane and isobutane). Decane (C10H22) has seventy five isomers, and a molecule with 20 carbon atoms (C20H42) has over ...
The first coolant 201 is composed of 0.5% methane, 49.5% ethane, 49.5% propane and 0.5% isobutane. The two tables below show the advantages of incorporating ethylene into the second coolant 103. Table 1 relates to a plant operating according to FIG. 1 and Table 2 relates to a plant opera...
Actually, butane is blended into gasoline, and isobutane is used in alkylate units to produce high-octane alkylate which is also blended into gasoline. The others can be used as fuel gas in a refinery if economics dictate. So it isn't like NGLs constitute a low-value product. Even the sh...
The aromatic polyol may be, e.g., bis(4-hydroxyphenyl)-2,2-propane (generally known as bisphenol A), bis(4-hydroxyphenyl)-1,1-ethane, bis(4-hydroxyphenyl)-1,1-isobutane, bis(4-hydroxytertiarybutylphenyl)-2,2-propane, bis(2-hydroxynaphthyl)methane, 4,4′-dihydroxybenzophenone, 1,5-di...
