WebHá 2 dias · When the temperature was increased to 300 ˚C, the yields of BTX and C 2-C 4 alkenes reached their maximum, whereas less than half the amount of C 2-C 4 alkanes was obtained compared to the value at 250 ˚C; this illustrates a secondary transformation of C 2-C 4 alkanes which can be effectively initiated by an induced MW electric field. WebThis page looks at the polymerisation of alkenes to produce polymers like poly (ethene) (usually known as polythene, and sometimes as polyethylene), poly (propene) (old name: polypropylene), PVC and PTFE. It also looks briefly at how the structure of the polymers affects their properties and uses. Poly (ethene) (polythene or polyethylene) WebAlkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings ), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
