The objectives of this experiment are to demonstrate a separation of a mixture by using steam distillation and next to prove that Dalton’ Law and ideal gas law are applicable in steam distillation. Dalton’s Law; While Ideal Gas Law; This experiment is conducted by placing 2mL of Turpentine and 15mL of water into

Steam Distillation 6.6.12 Aim: To isolate and extract citrol from lemongrass oil using steam distillation. Theory: Impure chemicals are usually purified using distillation‚ allowing the changes in boiling points to separate the substances. Chemicals with high boiling points decompose before reaching the temperature necessary for separation‚ leading to the invention of steam distillation. The contamination is separated at lower temperatures and allows the separation of chemicals from their

purpose of this experiment was to isolate the aromatic hydroxyl compound‚ eugenol from crushed cloves using steam distillation. After conducting the distillation‚ the expected two layers were not visible in the centrifuge tube. Subsequently‚ the extraction and evaporation did not produce the expected oil. This result is probably due to the collection of only water vapor during distillation. From another group’s data‚ 3.80% of the oil was recovered from the cloves in which the major component is eugenol

1 Section 2 – 12:30 to 2:20 Distillation and Fractional Distillation Distillation and Fraction Distillations Purpose: The purpose of distillation is to purify a liquid. Distillations are use to purify contaminates out of water to obtain clean pure water‚ as well as‚ to separate mixtures of liquids into their individual components; e.g. methanol and water. Objective: Distill methanol from water using a simple distillation apparatus and fractional distillation apparatus to determine which

ranged from about 77 degrees in fraction 1 to about 89 degrees in the fraction 10. Next‚ the toluene stayed relatively the same temperature throughout the first 6 fractions at around 69 degrees and then drastically shot up to 100 degrees by the end of fraction 10. This is due to hexane having a lower boiling point and being able to steadily increase through each fraction evenly as temperature rises while the toluene‚ because of its higher boiling component‚ needed the higher temperature in order for higher

Principles of Distillation What is distillation? Simply‚ distillation is the process in which a liquid is vaporized (turned to steam)‚ recondensed (turned back into a liquid) and collected in a container. Nature uses a form of distillation to turn salt water (seawater) into fresh water (rain). Why do you use distillation to recycle waste solvents? Solvent-based waste contains volatile material (solvents) and non-volatile material (contaminants like paint‚ ink‚ grease‚ fiberglass‚ etc.). Many of the

SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for
