Here the question is preparing (4:1) hexane:ethyl acetate.
It is used as mobile phase in chromatography.
Preparation process;
Take 80ml of hexane in a fladk and add 20 ml ethyl acetate. Shake well, use as a mobile phase.
Can any doubt give me comment
Thank you
A TLC plate was run in 1:1 ethyl acetate and hexane, but when developed the plate only showed baseline spots. What change could be made to get the spot(s) to move further up the plate? -Spot a new plate and run again in the same solvent system -Spot a new plate and run in neat hexane -Spot a new plate and run in 1:2 ethyl acetate/hexane -Spot a new plate and run in 2:1 ethyl acetate/hexane
The solvent: 70/30 (hexane/ethyl acetate) Compounds: Hexane, 70/30 (hexane/ethyl acetate), and 95/5 CH2Cl2/CH3OH I r ry Pus uey.UUT TU eu puru The solvent for TLC works well as separating these 3 compounds. Rationalize why it was chosen, discussing polarity of solvent and the 3 ferrocenes.
What would happen if you had used a 1:1 mixture of ethyl acetate instead of hexane to elute your column? Would the product (DEET) have come out faster or slower? Would this have improved your separation, or made it worse?
Common solvents used in TLC analysis are hexane and ethyl acetate, the latter being more polar. A TLC has been performed on a mixture of two compounds. The solvent ran for 3 cm(plate length is 6cm) with 5% ethyl acetate in hexane. The two spots were not resolved, meaning they showed up too close to each other. What can you suggest to possible improve the results of the separation?
Let's say that you need to prepare a 66.8 % (v/v) solution of ethyl acetate (C4H8O2) dissolved in triethylamine (C6H15N). What mass (in g)of ethyl acetate would you need to prepare 560.5 g of this solution? density of ethyl acetate: 0.902 g/mL density of Triethylamine: 0.726 g/mL
Question 2 Predict how NMR can distinguish between ethyl acetate and methyl propanoate? ethyl acetate methyl propionate
How many grams of ethyl alcohol are produced by reaction of 3.4 mol of ethyl acetate with H2H2 ?
How would you know if butyl acetate and ethyl acetate separated by distillation? Explain your answer in detail.
3. A constitutional isomer of ethyl acetate has a retention time somewhat less than ethyl acetate itself. Does this alternate isomer have a stronger or weaker intermolecular interaction with the stationary phase of the GC column? Explain briefly. 4. The literature value for the boiling point of ethyl acetate is 77.1 °C at sea level (standard one atmosphere pressure, 101 kPa). A student wished to purify some ethyl acetate while working on a project at the shore of the Dead...
Question 10 1 pts What hazard classification would you expect a 90% ethyl acetate/10% hexane mixture to have? Flammable liquid Corrosive Toxic Flammable solid Question 16 1 pts The TLC diagram shown represents the analysis of three different compounds. Which of the three columns is/are likely to represent a pure compound, and why? 0 0 2 * 3 Columns 1 and 3, because there is only one spot in each. Column 2 only, because there are two spots present Columns...
