The pendant group could be chosen from a number of
alkene functionalized systems.
The content of hydrocarbons (mainly
alkenes and aromatics) and also oxygenates (methyl tert-butyl ether, ethanol, etc.) in petrol determines the type and amount of additives to be used.
All chromatograms are dominated by alkanes and
alkenes with 8-32 carbon atoms, and the peak from each n-alkane is accompanied by a peak from the corresponding n-alkene.

alkenes efficiently catalyzed by Mo salen supported on surface-modified halloysite nanotubes," Chinese Journal of Catalysis, vol.
The in situ produced peroxy acid then oxidises the
alkene, affording the respective epoxide and regenerating the carboxylic acid.
Statistical parameters were also calculated for total alkanes [C.sub.2]-[C.sub.5] and total
alkenes [C.sub.2]-[C.sub.4] as well as for geochemical ratios [C.sub.1]/[SIGMA]([C.sub.2]-[C.sub.5]), [C.sub.2][H.sub.6]/[C.sub.3][H.sub.8] ([C.sub.2]/[C.sub.3]), and [C.sub.2][H.sub.6]/[C.sub.2][H.sub.4] ([C.sub.2]/[C.sub.2=]).
Because of the absence of C-C bonds in the C-O chain structure of [PODE.sub.n], there is no pathway leading to the formation of
alkene. Instead of C=C, C=O is formed in the reaction classes (4) and (11).

Alkene Compound," Peter Rulon Stevenson and Jeffrey M.
In this system, II free radical attacked the [beta]-carbon of V free radical to generate VII free radical and alkyl radical with molecular weight of 141, whereas alkyl radical lost H atom and formed the
alkene with molecular weight of 140 (Scheme 1(j and k)).

Regarding alkyne hydrogenation, the major aim is to avoid hydrogenation to single bond and in the case of non-terminal alkynes is to give superiority to the extreme conversion and selectivity to the (Z)-
alkene [3-5].
Generally, aromatic and
alkene compositions were highly contained in JIS No.1 gasoline as a high RON fuel composition.
In addition, the student used
alkene, the low-price and eco-friendly substance, as a prefix substance for interaction rather than the epoxide expensive substance, which is typically used to prepare Cyclic Carbonate through a nano-meter industrial catalytic.
If only the alkyne carboalumination could be modified for discovering the corresponding
alkene carboalumination reaction with suitable chiral zirconocene derivatives, we would most likely discover a catalytic and enantioselective C--C bond-forming reaction, namely the ZACA (Zr-catalyzed asymmetric carboalumination of
alkenes).
Therefore, we report herein the modification process of the epoxy resin with compounds having epoxide, ester and
alkene groups and how the modification process affects mechanical properties of the epoxy resin.
