Properties of Alcohols and Phenols Experiment #3 Objectives: To observe the solubility of alcohols relative to their chemical structure‚ to perform chemical tests to distinguish primary‚ secondary and tertiary alcohols‚ and a color test for phenol. Introduction The general formula of an alcohol is ROH in which the R is an aliphatic hydrocarbon group. Alcohols may be looked upon as derivatives of water‚ HOH. One hydrogen of water is substituted by an alkyl group‚ R. Like water‚ alcohols show hydrogen

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 and LiCl to form Jacobsen’s catalyst. The synthesized Jacobsen’s catalyst was used to catalyze the epoxidation of dihydronaphthalene.

EFFECTS OF VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile
