Lab report analysis of hydrocarbons

Prepare a small, dry test tube. A brief introductory video clip on this subject is available by clicking here. This is followed by the formation of carbocation which was attacked by the hydrogen sulfate ion.

BirdDog System Support Log-in and system support, including password resets, are available to customers on a 24x7 basis by calling, toll-free, The procedure tells you that if no reaction occurs i. Aluminum chloride is very Lab report analysis of hydrocarbons reactive toward water.

This is usually done only when required for purposes other than energy measurement, such as hydrocarbon dew-point calculations, emissions reporting, process or reservoir modeling, etc.

Petroleum Analysis

System support requests or questions may also be submitted via e-mail to BirdDogSystemSupport birddog. Next, samples are analyzed on the instrument of choice, i.

Lab Report on Hydrocarbons

Addition of the bromine solution to cyclohexene resulted to the disappearance of color of the bromine solution after each drop and agitation. Samples are extracted, injected or thermally desorbed, depending on the sampling media and the analytical method that has been chosen.

Our experienced analysts have broad capabilities related specifically to delivery of air monitoring services. You must close the AlCl3 bottle tightly immediately after use; otherwise the contents become deactivated by reaction with water vapor in the air.

The bromine and toluene reacted partially, leaving only some yellow color instead of a strong red, OR you accidentally added too little bromine. Bromine can react with an alkane, but this reaction requires heat or ultraviolet light to be successful, and the reaction is a substitution, not an addition: Data is quality-reduced, meaning the analyst interprets the data from the machine that has been used.

The procedure was a little vague about how to recognize a reaction although the background explained it better. This may not have been possible if the lab was performed at night, for example.

In general, there will be less of each individual molecular species in the gas for each higher carbon number since the vapor pressure decreases with carbon number i. It is also worth noticeable that cyclohexane and cyclohexene gave a positive result for H2SO4. Then obtain an IR spectrum of your unknown and you will make a positive identification by comparing it to the IR spectra given in appendix 9.

It must be thoroughly dry since AlCl3 reacts with water. Did the red bromine gradually fade to yellow, or was it yellow from the start? After consulting with analysts about samples to analyze, we determine the appropriate instrumentation and correct analytical method to use for each project on a case-by-case basis.

The actual experiment has already been performed and the results have been recorded in the table last page. There are 7 commonly occurring C6 components, 15 common C7 components, and an increasing number for each additional carbon number.

Reaction of hydrocarbons with bromine: It should turn bright orange-red with a compound containing an aromatic ring.

Chemical Analysis [Polycyclic aromatic hydrocarbons] in Crude oil

Once the data has passed scrutiny, it is sent to the client in either a lab report which can detail concentrations, or a more detailed report with recommendations and guidance as to how to mitigate exposures if values are determined to be excessive.

Upon receiving the samples at the lab, we perform an inspection of the chain of custody and match all listed samples with samples that we receive.

Bromine is a reddish brown liquid, so if it reacts with another chemical, the initial red color will disappear or at least fade.

Add 2 mL chloroform CHCl3 and drops of your test compound. Those that have a different chemical formula e. This works because most of the six-carbon hydrocarbons have the same chemical formula and very similar heating values, compressibilities, etc.Experiment #3 Hydrocarbons Page 3 φ φ φ φ v v m m m n = s s = sin sin vacuum l material i g h t b e a m lig h t b e a m Figure 2 - Index of Refraction In some molecules, even though the net charge is 0, the distribution of positive.

ALS Environmental offers PAH testing (polynuclear or polycyclic aromatic hydrocarbons) in air, water, soil, sediment, tissue, industrial products, and analytical procedures use various laboratory techniques and instrumentation, including Gas Chromatography/Mass Spectrometry (GC/MS), and High Performance Liquid.

Lab Analysis VOCs, RSCs, PAHs and Aldehydes Airzone offers laboratory services to support ambient air, occupational health & hygiene, indoor air quality, other projects and external client activities.

SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports.

Three fields of study are composed within this memo that includes Electrical Engineering, Environmental Engineering, and Petroleum Engineering. “Electrical Filters,” (Electrical), written by Joe Schmoe, is a.

Reactions of 3 Hydrocarbons: Cyclohexane, Cyclohexene and Toluene
