Steam Distillation: the Isolation of Limonene

move Distillation: The isolation of limonene 1. Purpose The purpose of the experiment is to be familiar with the use of steam distillment, to learn how to carry an native solvent and impinge on a volatile gas by a rotary evaporator, and to determine the purity of the limonene. move distillation was utilize because it is a supererogatory type of distillation specially for temperature sensitive materials. Dichloromethane was used to extract the sedimentary variety show. atomic number 12 sulfate was used to take over water and simple filtration was used to remove magnesium sulfate. synchronous converter evaporator with a steam privy was designed to remove the solvent. eventually gas chromatography was used to signalise the purity of the limonene. 2. Mechanism 3. Procedures prototypic I squeeze the orange in order to beat out its liquid to put in into the 250 mL flask. past I put the thermometer into the thermometer adapter and connect it with Three -way adapter. consequently we hardly acquit it to be distilled. It takes a long time. later that, we will scramble the distilled water and slabber it. Then we just add magnesium sulfate to absorb water and filter it. What we do following(a) is to put it into the rotary evaporation. Then we just give the test to TA in order to get the peak. 4.

Result and backchat Steam distillation is a special type of distillation especially for temperature sensitive materials. Many organic sharpens, in this case, limonene, feed to decompose at high free burning temperatures. Steam is introduced to the distillati on system. Therefore the boiling point of th! e deepen is deject and allows it to evaporate at lower temperature before the compound becomes inappreciable. The computer storage 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 upstage using rotary evaporator....If you want to get a in effect(p) essay, order it on our website: OrderCustomPaper.com
