(+)- and (-) – Carvones Purpose Compare (+)- carvone from caraway oil to (-)- carvone from spearmint oil‚ using gas chromatography. Experimental Odor: Smell containers of spearmint and caraway oil and two carvones. Analytical Gas Chromatography: Put five individual samples by different group members into Gas Chromatograph to calculate the percent composition. Claudia tested S- (+)- carvone and R- (+) – Limonene‚ Daniel tested Spearmint oil (pure)‚ Greg tested R- (-)- carvone and I tested Caraway

Jacobsen’s Method of Epoxidation of an Alkene | | Abstract Various types of reactions were completed to first create and then use Jacobsen’s catalyst in the asymmetric epoxidation of an unknown alkene with bleach in the laboratory. The chiral epoxide synthesized was then characterized with GC/MS and NMR. With this information the unknown alkene was able to be identified as 4-chlorostyrene. Introduction Organisms have evolved with mechanisms that use specific enantiomers of molecules

Asymmetric Epoxidation of Dihydronaphthalene with a Synthesized Jacobsen’s Catalyst Justin Lindsey 12/08/96 Chem 250 GG Professor Tim Hoyt TA: Andrea Egans Abstract. 1‚2 diaminocyclohexane was reacted with L-(+)-tartaric acid to yield (R‚R)-1‚2-diaminocyclohexane mono-(+)-tartrate salt. The tartrate salt was then reacted with potassium carbonate and 3‚5-di-tert-butylsalicylaldehyde to yield (R‚R)-N‚N’-Bis(3‚5-di-tert-butylsalicylidene)-1‚2-cyclohexanediamine‚ which was then reacted with Mn(OAc)2*4H2O

Activity of Carvones Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 10/29/03 Abstract: The objective of this experiment is to use Gas Chromatography to distinguish between two enantiomers of carvone from caraway oil and spearment oil and to find the 2 carvone’s optical activity as well as percent carvone in spearment and caraway oil. It was found that S-carvone had an optical activity of 0.0047 and R-carvone had an optical activity of 0.516 and that spearment oil is 59% carvone and caraway

R as a Tool for Statistical Analysis Getting Started with R (Part I) The > is called the prompt. If a command is too long to fit on a line‚ a + is used for the continuation prompt. Assign values to an object using the equal sign (=)‚ e.g.‚ >x=11. Note: R is case sensitive Print command allows you to see the value in an object You may also use the less than sign and a dash to create an arrow (<-) to assign values. An equal sign (=) is also used to assign values. R easily overwrites
