Butyne is an alkyne that contains 4 carbon and 6 hydrogen. It contains one triple bond and has two isomeric organic chemical compounds: 1-Butyne (ethylacetylene)
2-Butyne is of interest to physical chemists because of its very low torsional barrier and the problem of determining that barrier using high-resolution infrared spectroscopy. Analysis of its spectrum [ 3 ] leads to a determination that the torsional barrier is only 6 cm −1 (1.2 × 10 −22 J or 72 J mol −1 ).
BHT is also used as an antioxidant in products such as metalworking fluids, cosmetics, pharmaceuticals, rubber, transformer oils, and embalming fluid. [25] [26] In the petroleum industry, where BHT is known as the fuel additive AO-29, it is used in hydraulic fluids, turbine and gear oils, and jet fuels.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane.
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.
Butyrophenone is an organic compound with the formula C 6 H 5 C(O)C 3 H 7. It is a colorless liquid. It is a colorless liquid. The butyrophenone structure—a ketone flanked by a phenyl ring and a butyl chain —forms the basis for many other chemicals containing various substituents .
tert-Butylamine (also erbumine and other names) is an organic chemical compound with the formula (CH 3) 3 CNH 2.It is a colorless liquid with a typical amine-like odor. tert-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, sec-butylamine and isobutylamine.
That implies a stabilization energy of 3.5 kcal/mol. [25] Similarly, the hydrogenation of the terminal double bond of 1,4-pentadiene releases 30.1 kcal/mol of heat, while hydrogenation of the terminal double bond of conjugated (E)-1,3-pentadiene releases only 26.5 kcal/mol, implying a very similar value of 3.6 kcal/mol for the stabilization ...
