    • 2 Pages

    any impurities such as water, alcohol, alkanes, etc. Methanol is transferred to storage tanks which is specially assigned for crude Methanol. The Methanol will then be feed to the next part of the operation which is purification. In two different distillation columns, Methanol is purify to achieve the product quality which is required. In the first column, low boiling impurities known as light ends are removed. Light ends are materials that have a lower boiling point than Methanol. When heated,…

    point of 100˚C, while the sand’s melting point is at 1650˚C. 2. Sugar and water: Sugar is similar to salt as both are soluble crystals and would easily be separated by distillation because the evaporating point of water is 100˚C and the melting point of sugar is 180˚C. 3. Oil and water: Oil and water can be separated by distillation because the boiling point of water is 100˚C and oil has boiling point of 300˚C. 4. Sand and gravel: To separate sand gravel is. to use a sifter and have a mesh with…

    Introduction In this weeks lab each group is assigned an unknown alcohol and an unknown carboxylic acid for testing. Each group then synthesizes an unknown ester from a Fisher Esterification reaction of the given unknown. Once an ester product is obtained, 1H and 13C NMR, boiling point, and smell testes are run on the final product in order to identify all the given unknowns. Procedures The first step of this week’s lab was to mix 3mL of the unknown alcohol and 6mL of the unknown carboxylic…

    reacted in reactor (R 2301) to produce 95% of MTBE at a pressure that equals 3400 kpagauge and temperature of 120o C. In addition, butane column (V 2304) is available and it has two objectives, which are reaching 98% to 99% of MTBE production and distillation of MTBE from other components such as Methanol and unreacted isobutylene. MTBE transferred to the storage tanks and the other compounds go to Water wash column (V 2306). V 2306 is the next column that extracts Methanol from the mixture of…

    Purpose: As derivatives of carboxylic acids, esters are abundant compounds that often contribute to the fragrances in flowers, fruits, and coffee. Esters are synthesized from either organic or inorganic acids through a process called esterification. In this reaction, a carboxylic acid (RCOOH) and an alcohol (R’OH) mix in the presence of a strong acid catalyst to form a neutral, water-insoluble ester (RCOO’R) that gives off a pleasant smell. The following is an example of this reaction: The…

    of ground nutmeg was transferred to the round-bottom flask (RBF) using the plastic funnel. Three milliliter of tert-butyl methyl ether and two or three boiling chips were added into the flask. The black plastic connector was used just like the distillation column with air condenser set-up. The flask was clamped to the ring stand using 3-pronged clamp. The flask was lowered into a slightly depression in the sand without touching directly to the sand. The mixture was then boiled gently at the…
