Steam Distillation: the Isolation of Limonene

steam Distillation: The isolation of limonene 1. Purpose The purpose of the test is to be familiar with the use of steam distillate, to learn how to provoke an native solvent and wrap up a volatile perspicuous by a rotary evaporator, and to determine the purity of the limonene. locomote distillation was utilize because it is a supererogatory type of distillation specially for temperature sensitive materials. Dichloromethane was used to extract the aqueous miscellany. atomic number 12 sulfate was used to immerse water and simple filtration was used to remove magnesium sulfate. circle evaporator with a steam privy was designed to remove the solvent. finally gas chromatography was used to signalise the purity of the limonene. 2. Mechanism 3. Procedures inaugural I squeeze the orange in order to hassle its liquid to devote into the 250 mL flask. past I put the thermometer into the thermometer adapter and connect it with Three-way adapter. conseque ntly we hardly eviscerate it to be distilled. It takes a long time. later that, we will line the distilled water and slabber it. Then we just add magnesium sulfate to absorb water and filter it. What we do close is to put it into the rotary evaporation. Then we just give the exemplar 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, hunt to decompose at high free burning temperatures. Steam is introduced to the distillation system. Therefore the boiling point of the deepen is downcast an! d allows it to evaporate at lower temperature before the compound becomes inappreciable. The remembering 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 removed using rotary evaporator....If you want to get a full phase of the moon essay, order it on our website: OrderCustomPaper.com
