Prelab 3 reduction of a ketone

Use a regular jacketed condenser but do not connect water tubes or run water through as one normally would do. Note that the diastereomers produced by the reaction have different Rf values, unlike enantiomers.

Carbonyl reduction

Using sodium tetrahydridoborate sodium borohydride Sodium tetrahydridoborate is a more gentle and therefore safer reagent than lithium tetrahydridoaluminate. NaBH4 is very reactive.

Choose the first balance. The first quiz will occur on the fourth day of class. Remember that the initial reaction is carried out in carefully dried ethoxyethane. The book is organized based on essays and topics of current interest and covers a large number of traditional organic reactions and syntheses, as well as experiments with a biological or health science focus.

The oxidation occurs in reasonable yield and provides a good introduction to the use of infrared sDectroscoDv. In what follows, I am choosing one out of many different methods. TLC procedures will be similar to those specified in Pavia.

Third, we found ether extractions unnecessary when the acetic acid is neutralized with sodium hydroxide followed by a steam distillation of the cyclohexanone. Overview - You will oxidize a chiral alcohol, borneol endo-1,7,7-trimethylbicyclo[2.

This will take you to another part of the site. The rising cost of common chemicals has prompted most chemistry teachers to reconsider common practices. Bicarbonate Test for an Acid Mix the contents until precipitation is observed.


Since we found it availahle only in 5-gal containers, there was suhstantial waste in small to medium-sized classes. Bleach is available inexpensively in half-gallon and gallon containers and standard brands do not reauire tit r a t i k Recently, the use of hypochlorite bleach has been reported for the oxidaton of secondary alcohols 7.

In reference to the situation mentioned in 2, devise a method to perform a controlled addition of bleach, monitoring temperature, without allowing noxious vapors to escape from the reaction mixture.

Include a descriptive entry for every web site, article, book, handout, or person other than your team members or your professor that is relevant to your project.

Use a very small test tube for this extraction. Three unknown compounds, A, B, and C, were all optically active, all had strong IR bands in the cm—1 region. The end are chloride and the desired ketone; no toxic metal ions are present. Technique 35 see the part on obtaining IR spectra of solid samples.

Biodiesel from Other Oils. Chlorine eas is a resoiratorvand eye irritant.A ketone has two alkyl (or aryl) groups bonded to the carbonyl carbon. An aldehyde has one alkyl Ch18 Ketones and Aldehydes (landscape).doc Page 3 It is very difficult to reduce a carboxylic acid back to an aldehyde and to get the reduction to stop there.

Aldehydes themselves are very easily reduced (more reactive than acids), and so. Mannich Reaction. This multi-component condensation of a nonenolizable aldehyde, a primary or secondary amine and an enolizable carbonyl compound affords aminomethylated products.

Click the structures and reaction arrows in sequence to view the 3D models and animations respectively. Nitration of benzene firstly involves the formation of a very.

Reduction of Camphor

Revision Determination of the Rate Law for the Oxidation of Oxalic Acid Rate of Reaction = - ≅ (Eq. 3- when t ~ small) However, if we are timing how long it takes for all the Permanganate to be consumed, 3. The reaction under study is an Oxidation-Reduction reaction.
