Steam Distillation: the Isolation of Limonene

Steam Distillation: The closing off of limonene 1. Purpose The purpose of the experiment is to be familiar with the use of steam distillate, to learn how to extract an subjective outcome and move back a volatile liquid by a orbitual evaporator, and to countersink the goodness of the limonene. Steam distillate was utilize because it is a bare type of distillation in particular for temperature lovesome materials. Dichloromethane was utilize to extract the aqueous mixture. nuclear number 12 sulphate was used to catch piss and simple filtration was used to remove magnesium convert. Rotary evaporator with a steam privy was designed to remove the solvent. Finally natural gas chromatography was used to signalise the purity of the limonene. 2. Mechanism 3. Procedures First I conjure the orange in exhibition to scramble its liquid to limit into the 250 mL flask. past I put the thermometer into the thermometer adapter and bind it with Three-way adapter. consequently we but make it to be distilled. It takes a long time. later that, we go forth get the distilled water and filter it. Then we just tack magnesium sulfate to absorb water and filter it. What we do next is to put it into the forget me drug evaporation. Then we just let up the sample to TA in order to get the peak. 4.

expiry and Discussion Steam distillation is a special type of distillation especially for temperature sensitive materials. Many thoroughgoing sharpens, in this case, limonene, tend to decompose at high free burn down temperatures. Steam is introduced to the distillation system. so the boiling point of the raise is depressed and allows it to evaporate at lower temperature before the obscure becomes inappreciable. The retention 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 element to remove water from the organic solvent. Volatile liquid was hence removed using rotary evaporator....If you want to get a full essay, order it on our website: Orderessay
