cyclic hydrocarbons การใช้

• Platinum, a chemically similar catalyst, catalyzes dehydrogenation of five-and six-member cyclic hydrocarbons into benzene.
• Additionally, exposure to chlorinated cyclic hydrocarbons can lead to a deficiency in the activity of uroporphyrinogen decarboxylase, causing the buildup of excess uroporphyrinogen.
• In some cases the sensitization is caused by non-living exogenous irritants such as cyclic hydrocarbons ( for example, resinous vapours ) or pesticides and herbicides.
• "' Quadricyclane "'is a strained, multi-cyclic hydrocarbon with potential uses as an additive for rocket propellants as well in solar energy conversion.
• Enediynes generally undergo the Bergman cyclization at temperatures exceeding 200 癈 . However, incorporating the enediyne into a 10-membered cyclic hydrocarbon makes the reaction more thermodynamically favorable by releasing the ring strain of the reactants.
• However, when the cyclic hydrocarbons would be hypothetically polymerized ( to polyethelene ), still a volume shrinking would appear overall ( as polyethelene has a density of 0.92 g?" cm-3 ).
• The pyrolysis gasoline typically consists of C 6 to C 8 aromatics, heavier aromatics containing 9 to 11 or 12 carbon atoms, and non-aromatic cyclic hydrocarbons ( naphthenes ) containing 6 or more carbon atoms.
• To develop fuels suitable for cold applications, Keasling s laboratory engineered " E . coli " and " S . cerevisiae " to produce branched and cyclic hydrocarbons using the isoprenoid biosynthetic pathway : isopentanol, a drop-in replacement for gasoline; pinene, a replacement for jet fuel; and bisabolene, a replacement for diesel fuel.
