  • Propylene Glycol Production Process Report

    Chapter 3 Process description and modeling 3.1 Process Description of Propylene Glycol Production Process The physical properties of propylene glycol are colourless and clear syrupy liquid when exists at room temperature. Besides than in liquid form, it also may exists in vapor form in air. In order to produce a colourless and odourless chemical, propylene glycol (C3H8O2, PG) involve in the reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide…

  • Isobutylene Research Paper

    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…

  • Essential Oils

    Introduction Essential oils (EOs) are aromatic volatile liquids obtained from plant materials whether they are vascular plant or nonvascular plants including; buds, flowers, fruits, seeds, leaves, twigs, bark, wood ,roots and herbs. Citrus plants constitute one of the main essential oils sources (Burt, 2004; Hammer, 1999). They belong to Rutaceae family, which originated from tropical and subtropical south-eastern parts of the world (Sawamura, 2010). Citrus species were cultivated in China long…

  • Baking Soda Vs Vinegar

    Introduction: A chemical reaction occurs when you mix baking soda and vinegar. The type of reaction that occurs when you mix the two is called a chemical reaction, the chemical property that is used is called reactivity. Some of the evidence that proves that a chemical change is occurring is when you start to hear a sizzle sound and gas starts to be produced. When the gas starts to produce you will see the bubbles start to rise. The two types of matter that are creating this reaction are called…

  • Acetanilide Pyridinium Tribromide

    The experiment began by weighing 2.0g of acetanilide into a round bottom flask and adding a stir bar. 20ml of glacial acetic acid was added to the flask and was covered with a watch glass. The solution was stirred until the acetanilide was dissolved. The flask was brought to the hood and 7.0g of pyridinium tribromide was added and then stirred for about 30 minutes with a watch glass as a cover. While stirring, 10% sodium bisulfite was added in 1ml increments until the orange/red color…

  • Analysis Of Apricot

    Raw material: Two sweet varieties of Apricot (Prunus Armeniaca L.) namely Marghulam and Halman fully ripened fruits were collected from Gilgit Baltistan region in Northern Areas of Pakistan. Apricots were sun dried under open condition (26-34+4 C, RH 41-52%) for 16-19 days. The sun dried Apricots were packed in polyethylene bags containing 01Kg of dried fruit. Further The dried samples obtained were ground to a fine powder and stored at 5°C in air-tight containers prior to further analysis.…

  • Flask Synthesis Lab Report

    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…
