Alkane

Identifying Alkanes Abstract: In this experiment, three unknown alkanes were identified by observing their physical and chemical properties. Alkanes are saturated hydrocarbons. The properties identified were qualitative observations, solubility, mass, fire test, boiling point, and volume, and density. Unknown one was identified as hexane, unknown two as pentane, and unknown three as heptane. The results were as unpredictable but understandable and the properties of the boiling points of the unknowns

Alcanivorax borkumensis is normally found in low abundances in the upper layers of the ocean but can become predominant in oil-contaminated open oceans and coastal waters.3 They have a profound ability to degrade and live predominately on alkanes. They are able to degrade alkanes up to C32, isoprenoid hydrocarbons and alkylcycloalkanes.3 This ability gives Alcanivorax a competitive advantage over other oil-degrading microbes. The third, and final, bacteria that I will be using in my experiment are Cycloclasticus

heat of combustion. The significance behind the scale of this graph where the experimental is lower that the theoretical, is how there is a pattern for which every fuel follows the same trend. Also it shows the average heats of combustion and which alkane has the leading heat output rate. Graph 2 Description: This graph is identical to experiment 1 graph 2 as it shows a pattern between the scales of carbon atoms. The higher amount of carbon in a longer chain results in a higher molar heat of combustion

the distillation of crude oil contains hydrocarbons in the C15 to C19 range. These hydrocarbons can be cracked by strong heating. (i) Write the molecular formula for the alkane with 19 carbon atoms. (ii) Name the type of reaction involved in cracking. (iii) Write an equation for one possible cracking reaction of the alkane C16H34 when the products include ethene and propene in the molar ratio 2:1 and only one other compound. (4) (Total 6 marks) 2. A compound of carbon, hydrogen and nitrogen

creatures trapped in sediments were converted by heat and pressure into crude oil. The most abundant of these mixtures are the ones containing hydrogen and carbon only. These hydrocarbons can take on a number of different forms, i.e. alkanes, alkenes and alkynes. They vary in size and shape and viscosity. By manipulating these chains of hydrocarbons you can create any number of useful substances as they are very adaptable. However there are lots of compounds that also contain

deduced from the experimental data using multiple linear regression. Comparison between measured ignition delay times and numerical predictions by five available kinetic mechanisms, namely NUI Galway pentane isomer model, JetSurF2.0 model, LLNL n-alkanes Model, NUI Galway Mech_56.54 Model and Wang’s DME model, was conducted. NUI Galway pentane isomer model shows good predictions for ignition delay times of DME, n-pentane and their blends which was conducted in this study to interpret the effect of

Kerosene and Gasoline are energy sourcing fuels that are distilled from crude oil. Crude oil is raw material consisting of many hydrocarbons, particularly 84-87% of carbon, 12-14% of hydrogen, oxygen, nitrogen and sulphur (1-2%) (Simanzhenkov, 2003 ) Page 4. It’s formed from fossil remains obtained from reservoir’s thousands of feet below the ground. There are 3 main groups of hydrocarbons; paraffinic, naphthenic and aromatic hydrocarbons. The paraffinic series of hydrocarbons have the general formula

Oil is the lifeblood of the world. Everything that is created by human hands can be related back to it in some way. In an age where there is a dwindling supply of oil it is becoming increasingly important to use every last bit of it to its full potential. After crude oil is removed from the ground it goes through a process called fractionation which separates the hydrocarbons found in oil based on their size. When fractionation is completed the separated hydrocarbons can be manipulated to form more

could have been the installation of insulation to the copper tin to reduce the amount of heat that escapes. If I was to do an experiment like this again I could use a different variable instead of alcohols. Instead I could investigate a chain of alkanes or alkenes, “in order to test alkenes I would have to look into the association double carbon bonds have with one

Purpose The purpose of this lab was to use simple distillation and fractional distillation to separate an unknown mixture of heptane and hexane. Additionally, gas chromatography (GC) was used to analyze and determine the percent composition of three samples taken during fractional distillation. Theory Hexane is mainly produced by refining crude oil and the exact composition depends on the source of the oil and the refining process. A significant amount of hexane is found in gasoline and other
