reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide (C3H6O, PO) with the presence of excess water and a small concentration of catalyst. The catalyst that plays the role in this reaction is the sulphuric acid.
The reaction occurs in the reactor at the reasonable rate which near the ambient temperatures. The temperature of the solution can rises due to the continuous reaction process. The heat reaction because of the temperature of propylene…
Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate
Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used…

The MTBE operation consists of various units; the focal units are De Iso Butanizer (DIB), Butamer, Oleflex and Ethermax. Methanol produced from QAFAC, mixed butane from QP NGL facilities and water with power from KAHRAMAA and small amounts of chemicals to be used such as: 10% Caustic, DMDS, PERC and Chlorine are the required raw materials needed to generate MTBE. Producing MTBE starts with passing the Butane mixture that is in the storage sphere at QAFAC through the DIB unit where the…
Spinach is a leafy green plant that is high in vitamins. Spinach gains its green color from the pigments it contains which help the plant absorb sunlight needed for photosynthesis. The main pigments are chlorophyll a, chlorophyll b, and β-carotene. Chlorophyll presents as a green pigment and is a porphyrin while β-carotene is a red-orange pigment and a carotenoid.  They are both found in all pants and are sensitive to exposure to light and air. β-carotene has been used in the…
It has two isomeric forms 1, 2, 3-triazole and 1,2,4-triazol with common molecular formula C2H3N3,and both have 69.06 molecular weight. ] 1, 2, 4-triazole derivatives simply exist in solid forms. 3, 4, 5-substituted 1, 2, 4-triazole derivatives melts on thermolysis when heated at high temperature3160C for half an hour. 1, 2, 4-Triazole derivatives are easily soluble in polar solvents and slightly soluble in non-polar solvents. However the solubility in non-polar solvents…
Slime is made by mixing together borax, glue, and water. Depending on the amount of borax added to the mixture will determine the density of the slime. For our experiment in class the independent variable was the borax. The dependent variable was slime. The control group was glue. It was important to keep the amount of glue, borax, and water constant throughout the experiment. In an experiment conducted in class it was hypothesized that the more borax added the denser the slime will be.…
Since ammonia is a weak base, it combines with acids to form salts. Liquid ammonia is commonly reacted with hydrogen chloride to form a cloud of ammonium chloride. Salts produced by the reacting ammonia with acids or known as ammonium salts and contain the ammonium ion, NH4+. NH3 also ionizes to a small extent with metal oxides and the halogens. Like water, ammonia undergoes molecular autoionisation to form its acid and base components, decomposing to NH4+ and NH2- (“CHEM-GUIDE”)…
standardize a sodium hydroxide solution as well as determine the molar concentration in as strong acid and the percent by mass of acetic acid in vinegar. We used volumetric analysis, also known as titration, in both experiments. The average molar concentration for NaOH was 0.2749 mol/L while the average molar concentration of the acid solution was .2493 mol/L.The average percent by mass of acetic acid in vinegar was found to be 12.3 %
The Purpose of experiment 9 was to prepare and…
its reaction with vinegar?
Aim: To find out how different amounts of baking soda (soda bicarbonate) affect the length of its chemical reaction with vinegar (acetic acid).
If the amount of baking soda is increased then the length of its reaction with vinegar will increase because there will be more soda bicarbonate for the acetic acid to react with.
