    How Does the 12% Efficiency Factor Influence Theoretical Yield in Distillation?

    Hey everybody, I just completed a small distillation lab for my high school chemistry class. We took a sucrose/water solution, added yeast to ferment it, and distilled it into ethanol for about an hour in the lab. I'm trying to write my lab report, and I've hit a huge stumbling block! One of...

    Low temp distillation of metals

    Is practical to employ fractional distillation methods on a mixture of two metallic elements with low BP - for example Hg and Zn? And no, I'm not trying to do this.

    Batch Distillation: Packing vs Plates for Reboiler of 250 Litres

    I need to know a few things. I am doing my internship and have been given a problem with very limited information. I have to decide whether to use packing or plates. The tower is to be used for several different mixtures. So everytime it has to be washed completely, whenever a new separation is...

    Designing a Distillation Column

    If you were to design a distil col and didn't know the feed conditions how would you go about starting. You know xd, xb, xf, R, Eq data. Theres 5 potential q's. Also how would u make enthpy diagram for PS. Thanks.

    How are the plates in a Fractional Distillation Tower regulated?

    My teacher can't explain it. My textbook is awful at it. So can someone explain clearly what the role of the fractionnating columns are; in the Fractional Distillation Tower.

    In general, what is the best type of column used for fractional distillation?

    Many university organic course laboratories use Liebig columns packed with glass beads. This is what I use, but I would like to know if there are better columns that can be used instead of this. I had a problem with this type of apparatuse before. The glass beads shot right through the $30...

    How Does Fractional Distillation Separate Different Hydrocarbons in Crude Oil?

    In the case of oil is that it contains hundreds of different types of hydrocarbons all mixed together can all be separated by distillation. To me is not clear why for a fractional distillation column when is used the differences in boiling temperature in the lower part are collected those...

    Distillation Techniques: Lab Safety and Best Practices

    I am planning on doing some distillation in the very near future; however, it has occurred to me that I have had no formal training in proper laboratory distillation techniques. Since I would very much like to avoid damaging my beautiful new glassware on my first attempt, I figured I would try...

    A distillation procedure, product safe to drink?

    Im attempting to make a distillation procedure with tap water so that i can drink it pure. I got a small can of pvc primer, i emptied it, and scrubbed it clean as best i could. Its sitting on a stop top right now getting as hot as it can possibly get so that all of the alcohols will evaporate...

    Why do different fractions form from fractional distillation?

    Fractions of distillation... Some of the fractions which result from fractional distillation seem to share carbons of the same length - yet these form different fractions. Why? Eg - Petrol is carbon chain length 4 - 12, naptha is 7 - 14 and kerosine is 11 -15; why the overlap when they boil...

    What is the Procrustean method for entanglement distillation?

    Please explain what's entanglement distillation and what's entanglement concentration. I'm mistaken to think that these two techniques are related somehow?
