Oil Distillation Lab Report

11. Methanol was filled in a test tube and placed into a water bath to heat up.

When carrying out this scientific technique you first need filter paper, tubing, clean solvent, and disposable dropper.

Record what the measurement of water in milliliters before placing the unidentified object into the graduated cylinder

Place the thermometer into the water and let it settle in order to ensure that the temperature has remained at 41°C.

We found that unknown 6 was Isopropyl alcohol. Its chemical name is isopropanol and the chemical formula C₃H₈O but is typically called isopropyl alcohol. Isopropyl alcohol is today used as a primary ingredient in rubbing alcohol. Is smells very unpleasant and is used for disinfecting pads used by medical professionals for tasks such as sanitizing small instruments, wiping down surfaces, and cleaning a patient’s skin before an injection. Since it is also a solvent, it has many cleaning uses. We predicted at once that is could be isopropanol because of its smell.

First, the 250-mL graduated cylinder, 100-mL graduated cylinder, and the 10-mL graduated cylinder were observed to see the volume of the liquid in each one. Then, one digit further was estimated, and the results were recorded. After that, the 25-mL graduated cylinder and the 50-mL beaker were cleaned and dried. Next, their masses were measured on the scale, and the results were rounded to the nearest thousands decimal place. Subsequently, the Erlenmeyer flask was filled with 100 mL of distilled water. Using the thermometer, the temperature was measured and recorded. Then, the 25-mL graduated cylinder was filled with 25 mL of distilled water, and its mass was measured and recorded. The density of the water was found using the temperature and the Density of water index. Moreover, the calculated volume of water was calculated using the formula of density, and the difference between observed volume and calculated volume was found. This process was then repeated using the 50-mL beaker and the results were recorded.

When the distillation was proceeding at a moderate speed at about the wanted temperature, the receiver was replaced with a vial as the condensed vapour sample (V) and the thermometer was read. Half of the vial was filled with the sample.

Two sources of error may have affected the experiment. Firstly, the experiment required volumes of liquid to be recorded while the vapours were distilling. It was impossible to accurately measure the volume of liquid at any given moment, as the meniscus was moving side to side. Secondly, the distillation was ended while there was still liquid in to round bottom flask. The composition and volume of this liquid were unaccounted for in the calculated

The experiment was designed to where ethanol can be produced and extracted from a fermentation solution. Fermentation is a necessary step because it converts sugar into acids, gases, or alcohol. It only occurs in yeast or bacteria, which was why yeast was used for the fermentation process in this experiment.

500 mL of distilled water were measured by using a 500 mL measuring cylinder, then is poured inside the 500 mL beaker containing both the powdered.

As the world’s population continues to grow every year, the demand in producing the basic needs of people is becoming high. Producing the basic needs takes a lot of work and energy, cooking oil is what people most of all want since it is made from renewable sources. John Lynch (2011) stated that different cooking oils have different uses, oils with bold flavors such as extra virgin olive oil is used for raw foods while vegetable oils like canola oil is best used for frying. Cooking oil are considered as renewable energy because of its ingredients can be obtained from renewable sources such as vegetables plants and seeds that have oil content like olives peanuts making it affordable and available.

This experiment is to determine the concentration of the solute copper sulfate pentahydrate, and the unknown solution, by passing different wavelengths of light through each solution.

Abstract — This experiment was conducted to familiarize the students with the procedures regarding distillation—to be more precise, the separation of ethanol from an alcoholic beverage—using a distillation set-up consisting of boiling chips, a Bunsen burner, a condenser, a thermometer and several other materials. In the end, it was discovered that one may actually separate a homogeneous mixture, given that the components of said mixture differ in volatility and that they utilize a complete distillation set-up and follow laboratory safety rules and regulations.

Chevron Phillips Chemical Company is the major producer of Cyclohexane. This successful company hoses the three largest cyclohexane plants in the world. Many are puzzled by how the production of cyclohexane seems to have become stagnant. Perhaps this is due to the cost of benzene increasing or the demand increasing. Through thorough investigation, the answer to this question and many more can be answered. There are two methods of obtaining cyclohexane. These two methods are fractional distillation of naphtha and hydrogenation of benzene. Research suggest that the hydrogenation of benzene is the most economical way to create our chemical of choice. According to ICIS, cyclohexane is used in the production of adipic acid used to

Fractional distillation is a method of separating miscible liquids using heat. This technique is used for the separation of liquids which dissolve in each other. Several simple distillations are completed during fractional distillation using only one apparatus. During the process a mixture is separated into several parts called fractions. Mixtures contain different substance with different boiling points, the differences in boiling points is the main reason fractional distillation is effective. The temperature at which a phase change occurs from liquid to vapor is the boiling point.
