  • Cyclohexene Lab Report

    Cyclohexene distillation A fraction containing primarily cyclohexene primarily cyclohexene and water is separated from raw cyclohexanone in Cyclohexene column. Raw Cyclohexanone is fed from storage tank to Cyclohexene Column via Cyclohexene heater. In Cyclohexene Heater, the feed is heated up to about 1200C with the heat carried by the bottom product from Alcohols column. The Cyclohexene column is operated at atmospheric pressure and temperatures of 850C at top and 1650C at bottom. The vapours…

  • Synthesis Of 4-Methoxyphenyl Cycloalkanol

    1-[Cyano(4-methoxyphenyl)methyl]cycloalkanol (VF-I) synthesized through the reaction of p-methoxyphenylacetonitrile and cyclohexanone using aq. NaOH and tetrabutylammonium hydrogen sulfate as PTC. NaBH4 and CoCl2 in 2:1 THF: H2O used for the reduction of VF-I to obtain 1-(2-amino-1-(4-methoxyphenyl)ethyl)cyclohexanol (VF-II). Further, venlafaxine derivative of the amino acid -carboxamide (VFCA-I toVII ) synthesized through coupling of N-Phthaloyl amino acid chloride derivative (2a-2g-…

  • Steam Distillation Lab Report

    This lab used techniques in steam distillation to extract crude oil from cloves. The cloves were boiled in a round bottom flask and using a hydrodistillation apparatus, the crude oil was separated from the cloves and sent into a clean flask. This step was used to separate the essential oils from the cloves (Setzer, W., 2008). The distillate was poured into a separatory funnel and extracted three times with dichloromethane to extract the water. After being extracted three times, a fifth of the…

  • Biochemical Qualitative Milk Lab

    Objective: In this laboratory experiment three objectives were sought after. These objectives were to first, create a separation scheme. Second, perform basic biochemical qualitative analytical tests. Lastly, identify the major components of milk. Introduction: The three goals in this experiment were desirable due to the fact that it gave knowledge on what is actually digested when milk is consumed. This is notably important to the children and adults that are lactose intolerant. 1 Many…

  • Redox Titration Case Study

    This study involves the use of redox titration to determine the amount of oxalic acid in the sample solution. The analyte solution containing oxalic acid was added with sulfuric acid and heated prior to the titration with permanganate. The persistent pink color signaled the end of the titration. The amount of the oxalic acid in the solution was found to be 8.941%. The redox titration was precise in the quantification of oxalic acid with a standard deviation of 1.327%. Introduction One of the…

  • Recrystallization Lab Report

    I. Abstract The experiment was about using a method of recrystallization to reform benzoic acid and unknown compound, and identifying that compound. The main principle is the polarity and solubility of compound. The compound was dissolved completely with distilled water in hot temperature and reformed back in cold environment. After the experiment, there were up to more than 50% of the compound being recrystallized and the unknown compound had the melting point at 165.2oC. The experiment…

  • Phylenedioxythiophene Case Study

    Abstract: A one dimensional variable range hopping type conduction is observed in Poly (3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT : PSS) films and the mechanism behind enhancement in conductivity in 3% dimethyle sulfoxide (DMSO) doped PEDOT:PSS film is due to the phase segregation of PSS on the surface and reduction of energy barrier between the conducting grains. Enhanced conductivity of PEDOT:PSS films and transparency more than 80% in the visible region makes PEDOT:PSS films…

  • Thermo Gravimetric And Differential Thermal Analysis

    [53]. The direct band gap energy (Eg) of Tb3+: SA crystals grown by SEST and SR methods are found to be 4.20 eV, 4.10 eV respectively, which is in good accordance with the reported values [54]. The value of band gap of Sulfamic acid was found to decrease with increase in impurity concentration and it is found between 4 and 5 [54, 55]. Fig(7). Plot of α vs. photon energy. 3.6 Thermogravimetry (TG) and differential thermal analysis (DTA) Thermogravimetry (TG) and differential thermal…

  • Pros And Cons Of Styrene Butadiene Rubber

    2.7 Styrene Butadiene Rubber Styrene Butadiene Rubber (SBR) belongs to the synthetic rubbers families that are derived from Styrene and Butadiene.[53] SBR is an aqueous dispersion of (25%) Styrene (CH2=CHC6H5) and (75%) Butadiene (CH2=CH-CH=CH2) copolymer as shown in Figure (2-1). The copolymerization of these two polymers may done by different ways. Mostly they copolymerized in an emulsion process, by dispersing a soap like surface acting agent where the materials are in water solution.[54]…
