Experiment 2: Fractional Distillation of a Mixture of Two Unknowns Background: Boiling is a process familiar to anyone who has cooked pasta or brewed tea. As heat is applied to a pan of water‚ the temperature of the water increases until it reaches 100°C (212°F). At this temperature‚ additional heat causes the water to bubble vigorously as the liquid water is converted into gaseous water‚ or steam. Most organic liquids will behave in a similar fashion. On heating‚ the temperature of the liquid

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

Although time may be recorded in seconds for mathematical or scientific calculations‚ fractions of hours are generally used to convey time as a full rotation of the minute hand on an analog clock signifies one hour. Therefore‚ although both measures produce the exact same answer‚ one would probably benefit from using measure 2 to tell time

Introduction Discovered by Georg Wittig in 1954‚ the Wittig reaction is a robust organic synthesis method for preparing stereospecific alkenes. In general‚ Wittig reactions involve an aldehyde or ketone and a Wittig reagent (triphenylphosphonium ylide) and result in the formation of an alkene product and triphenylphosphine oxide (side product). Stereospecific alkene products can be synthesized by adjusting the reaction reagents and conditions. In the 60 years since the Wittig reaction was discovered

July 14‚ 2009 Experiment 6: Fractional Distillation. Separation of Petroleum Hydrocarbons Abstract: A mixture of cyclohexane and toluene were separate from one another by fractional distillation in order to measure the composition of each fraction and prepare the sample for gas chromatography. Introduction: Distillation has been used since antiquity to separate the components of mixtures. This method has been used to manufacture different organic chemicals but the most recent application
