I need the cis and trans alcohol % from the attached information received by GC. The solvent was methanol. I believe this is done by using the peak area but I'm not sure about how to go about it.

Q. Preparation and properties of the diastereoisomers of 3,3,5-trimethylcyclohexanol
I need the cis and trans alcohol % from the attached information received by GC. The solvent was methanol. I believe this is done by using the peak area but I'm not sure about how to go about it.

A. Unfortunately I am unable to open .xlsx files at this moment (.xls files are ok), here is the guideline on how to determine cis-trans content from GC plot:

Chromatographic techniques separate mixtures of species based on their interactions with
a stationary phase (e.g. fused silica column) and a mobile phase (e.g. methanol). The column is usually derivatized to control its polarity (ranging from hydrophobic dimethylsiloxane to hydrophilic polyethylene glycol or any of a wide array of specialty coatings). The analyte molecules interact with the surface and exist ...

  • "Thankyou for the feedback. I have a few question though; With the first statistic about cost below... “According to Sigma-Aldrich catalog, cost of 1L octane is AUD $ 392.00, whereas the cost of 1L ethanol is AUD $196.00. Moreover, if ethanol is obtained from sugar industry as a by-product, it may cost even less. Source of oxygen is ambient atmosphere, so it costs nothing. So ethanol is much cheaper than petrol, in fact it is half-priced: AUD $ (392-196) = $ 196.” I didn't think it made sense because the cost of petrol per litre is normally a dollar something or even less than a dollar not a couple of hundred of dollars. For example, a statistic that I found in america was: "U.S. ethanol production costs are about $1.20 per gallon of ethanol, or $1.82 per gallon on a gasoline-equivalent basis." However, I was wondering whether you could find an Australian statistic. Also, you mentioned that H20 is not a greenhouse gas. However, in the combustion equations it is actually carbon dioxide and water vapour which are produced and they are both greenhouse gases. Finally, how do I calculate the energy efficiency of ethanol and petrol? "
