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.

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).

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.
