Steam Distillation: the Isolation of Limonene

move Distillation: The isolation of limonene 1. Purpose The purpose of the essay is to be familiar with the use of steam distillation, to learn how to deplume an native solvent and do away with a volatile smooth-spoken by a rotary evaporator, and to determine the purity of the limonene. steam distillation was utilize because it is a supererogatory type of distillation specially for temperature sensitive materials. Dichloromethane was used to extract the sedimentary intermixture. atomic number 12 sulfate was used to concern water and simple filtration was used to remove atomic number 12 sulfate. rophy evaporator with a steam privy was designed to remove the solvent. in the end gas chromatography was used to signalise the purity of the limonene. 2. Mechanism 3. Procedures rootage I squeeze the orange in order to dumbfound its liquid to tar pee-pee into the 250 mL flask. past I put the thermometer into the thermometer adapter and connect it with Th ree-way adapter. consequently we hardly need it to be distilled. It takes a long time. later that, we will get the distilled water and slabber it. Then we just add magnesium sulfate to absorb water and filter it. What we do bordering is to put it into the rotary evaporation. Then we just give the take to TA in order to get the peak. 4.

Result and preaching Steam distillation is a special type of distillation especially for temperature sensitive materials. Many organic sharpens, in this case, limonene, bleed to decompose at high free burning temperatures. Steam is introduced to the distillation sys tem. Therefore the boiling point of the dee! pen is low and allows it to evaporate at lower temperature before the compound becomes inappreciable. The belongings got for this lab was 0.216 for the solvent and the limonene is 1.000. To extract the solvent, dichloromethane was added and the aqueous mixture was extracted. Then, magnesium sulfate was added as a drying factor to remove water from the organic solvent. Volatile liquid was accordingly take away using rotary evaporator....If you want to get a well(p) essay, order it on our website: OrderCustomPaper.com
