Experiment 6 Data for Comparison

[Barbara Force]

Here is my data for  Experiment 6

[Kyle O'Connor]

Thank you for posting your data Barbara. Remember everyone, it's vital that you post your data to the google group so it can be shared for the distillation report. I will be paying more close attention to who actually posts their data and who doesn't this time around.

Remember, the data you will want to include is all variations on your specific solvent system. So for example, if you had methyl acetate/ethyl acetate solution, you will want to include all fractional distillations run with that solvent and the simple distillation.

If you have any questions, let me know!

Kyle

I attached my data!

Here is all my data for a fractional distillation (Vigreux) using the 1:1 Methyl Acetate:n-Butyl Acetate solution.

Here's my data using Fractional methyl:propyl and choreboy

[Alison Herendeen]

my data was for the fractional distillation (vigreux) and methy acetate: n-propyl acetate

[Kelly Garcia]

Everyone,

Thank you for sharing your data. Here are my results for fractional, carbonundrum, methyl acetate/ethyl acetate

8 fractions at 3 mL each

Temperature (degrees C)                       Refractive Index

52-57                                                   1.365

57-59                                                   1.3665

59-59                                                   1.367

60-60                                                   1.367

60-63                                                    1.3685

63-65                                                    1.370

65-68                                                    1.371

68-68                                                    1.3725

Boiling points for ethyl acetate seem off--either I wrote down a 6 instead of a 7, or there was some funky activity going on that I must elaborate on in my lab report. Either way, here it is.

Sincerely,

Kelly G.

[Kelly Garcia]

actually, ignore my final message. Just found in my lab notebook that those are, in fact, the true temperatures I observed. So the boiling points calculated (as well as refractive indexes) are correct. My apologies.

[Thomas Flagiello]

Attached is my data for simple distillation, 1:1 methyl acetate:ethyl acetate. My boiling points start out too high because my solution began boiling before the distillation head was set up (methyl acetate should have boiled out sooner)

Here's my data for fractional distillation (choreboy) of  1:1 methyl acetate:ethyl acetate:

Sample #	Refractive Index	Temperature
1	1.363	59
2	1.364	59
3	1.365	59
4	1.366	60
5	1.368	60-63
6	1.371	63-72
7	1.372	72
8	1.372	72

Hey look, it's some data!

[Nancy Ha]

Does anyone have data for the simple distillation of butyl acetate?

Nancy, 

The data I posted yesterday was for simple butyl acetate.

Hey guys. Sorry for taking long, but here's my data for a fractional distillation of n-butyl acetate with choreboy/glass beads. Note that the temperature did drop at certain points

Hey Will, 

Quick question, did you have a mix of Chor Boy and glass beads in the same fractional column? or is that data for one of the two packing materials? 

[William Ingram]

The material assigned was glass beads. A small amount of Chorboy was used to keep the glass beads packed into the column. Without it, the beads would fall straight through. I figured it would be useful to include that in the results. Sorry about any confusion!
