Propylene Glycol Synthesis Lab Report

Improved Essays
The propylene glycol is considered to be one of the common organic compounds which can be used in many life applications. It can be used in antifreeze, pharmaceuticals and many applications as well. It can be produced by hydrolysis of propylene oxide that is accelerated by the catalysis of base or acid.
The goal of the experiment is to produce propylene glycol using water and propylene glycol as a reactant to synthesis propylene glycol. The purpose of doing this experiment is to converge and install a conversion reactor, and also to simulate a process having separation and reaction using i-con software. UNIQUAC fluid package is used in this properties package list. The feed stream used in here is 3850kg /h which is propylene oxide and a stream of water feed of about 4890kg/h.

Figure1: - Proses Flow Diagram Production of Propylene Glycol (C3H8O2).

The two streams which are Propylene oxide and water feed were to be set at a temperature of 25 C and a pressure of 100 kPa. A combination of Propylene oxide stream and water feed stream will begin simulation in the mixer equipment that is labelled as MIX-100 shown in the figure1. For the combination or mixing the

Purity of production propylene glycol is (000)% mol at bottom product with (000)% mol water at Product stream. The bottom product does not exist of glycol oxide. For the top product that is stream 5 there is no output propylene glycol due to have been separated at the bottom product. The component at top product just only (000) % mol water and (000)mol% propylene oxide.

Figure2: - Proses Flow Diagram Production of Propylene Glycol (C3H8O2 with recycle).

Mostly at the top product where can reused back water by recycle in order it to prevent waste.
CONCLUSION
As the conclusion, this laboratory work is successful. The conversion was successfully.Thus, this simulation is acceptable due to purity of propylene glycol is above

    Ethyl vinyl ether was used to protect –OH on glycidol based on a literature reported protocal.59 In a typical procedure, 0.675 mol glycidol and 200 mL ethyl vinyl ether were loaded in a round-bottom flask, to which 1.25 g TsOH was then added. The reaction was allowed to proceed at room temperature (RT) for 3h. The resulting mixture was then purified by washing with 100 ml saturated aqueous solution of NaHCO3 for 3 times. The organic layer obtained was dried by MgSO4. After filtration of MgSO4, the excess ethyl vinyl ether was removed by rotary evaporation.…

    Figure 8. shows the response of the carbon chain atoms triglycerides to an infrared radiance, which the fuel with the catalyst responds faster to the transmitted heat is around 31% T, and the fuel without the catalyst is around 40% T. These results indicated that the atom's bond in triglyceride chain is weakened, the viscosity decreases and the fuel readily absorb heat. Moreover, the highest temperatures achieved (see fig 3) and the shorter burnout time (see fig 6) prove that the fuel with the catalyst has a great…

    Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a couple preliminary tests, which include physical state and smell.…

    In this experiment, pinacol was mixed with sulfuric acid, which protonated the pinacol, allowing it to form a better leaving group. Water is the leaving group off of the pinacol and the pinacol becomes a carbocation. The carbocation that is formed is a secondary carbocation so, rearrangement occurs. A methyl shift happens to form a tertiary carbocation, which is more stable than a secondary carbocation. Then, the remaining oxygen forms a double bond causing it to have a positive charge; allowing the carbon that had a positive charge to have a full octet and to be neutral.…

    Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol by using the Grignard reaction.…

    This separation resulted in a HETP value of 8.114cm. Given the large HETP value, with normal value in the range of 3-7cm, this particular column was not very successful in separating toluene and cyclohexane. This could be seen by the low number of theoretical plates, 0.912. A theoretical plate is one cycle of evaporation and condensation in a distillation. In general, having more theoretical plates results in better separation of the components given that there are more vaporization-condensation cycles, thus providing purer distillate.…

    Discussion Graph 1 displays the reaction time (in minutes) of how long it took for the Alka-Seltzer tablet to completely dissolve per trial. Graph 2 displays the averages of the reaction time which showed the higher the water temperature is, the faster the reaction time would be. At 65⁰C the average time for the Alka-Seltzer to completely dissolve was 1 minute 4 seconds followed by 1 minute 20 seconds at 35⁰C and ending with the highest average at 2 minutes 1 second (1.61). The hypothesis stated that hot water temperature would make the Alka-Seltzer tablet dissolve the fastest.…

    Through both simple and fractional distillation an equimolar solution of ethyl acetate and propyl acetate was seperated. After distilling 20 mL of the mixture the samples were collected in fractions, which were then analyzed using gas chromatography. The mole ratios of the distillations were converted to a percentage to analyze percent composition. Simple distillation yielded the following results: S1- 69.88% EA/ 30.12% PA, S2- 66.73% EA/ 33.27% PA, and S3- 46.42% EA, 53.58% PA. Fractional distillation yielded: F1- 82.66% EA/ 17.34% PA, F2- 79.89% EA/ 20.11% PA, F3- 44.50% EA/ 55.50% PA, and 5.65% EA/ 94.35% PA.…
