  • Iodoform Test

    Carbonyl compounds are the compounds the contain C=O group which is called carbonyl group (double bond oxygen to a carbon). There are many types of carbonyl compounds such as aldehydes, ketones, carboxylic acids, esters, amides etc. Aldehydes and ketones are the oxidation products of alcohols. Depending on the alcohol’s structure, the product obtained will be different. Primary alcohols have one carbon and two hydrogen atoms attached will produce aldehyde and then to carboxylic acid in two…

  • Liquid Compounding Process

    are brought from the Pre-weigh area for batching, the compounder assigned the batch must verify the chemicals and quantities brought from the Pre-weigh department and the weigh tickets must be affixed to the back of the Work Order (do not throw away). If there are any missing tickets stop the process and notify your supervisor for prompt follow-up, you may resume once the ticket and chemical is verified (this is an urgent matter and must be addressed immediately by informing the…

  • Feed Flow Rate Essay

    4.2.4 Effect of Feed flow rate (Fgr) on Product Distribution An increase in the flow of gas oil means an increase in the velocity of the gas oil feed, also a decrease in the residence time of the gas oil in the riser; hence a rise in the conversion of gas oil and yields of the products is expected(Akpa et al. 2010). When the flow rate of gas oil is increased, there is an increase in the heat inflow into the reactor, rate of cracking reactions are high, feed also spends less time in the reactor…

  • Contaminant Regeneration Essay

     Used Lubricant Regeneration Technology Most conventional processes for used lubricant regeneration involve physical separation and chemical treatments to remove the contaminants and impurities from used lubricants to make it suitable for re-use. Some of these technologies generate liquid effluents, solid wastes, and air emissions during the regenerating process. The types of wastes, effluents, and wastes vary with the technology and processes used, and the environmental control methods [CEPA,…

  • Sp2750 Experiment 4

    EXSS 2025 Motor Control and Learning Experiment 4: Reaction, Movement& Response Time in Decision-Making Tasks I. Question 3: (i) Why are multiple repeated trials in each task required (ii) Why do we need to complete checks on the data (identify errors etc)? (iii) Why was there a variable fore-period between the start of a trial and the appearance of a stimulus in the tasks? (iv) Why was randomization necessary from Task 1b onwards? (v) Why was 80%(congruent) vs 20%(incongruent) split used in…

  • Sn2-Butanol-2-Methylbutane Lab Report

    The goal of this lab was to conduct the reaction of 2-methyl-2-butanol with HCl to form 2-chloro-2-methylbutane, and to understand Sn1 and Sn2 reactions, in terms of how they are different and why one is more likely to happen over the other. The OH group in 2-methl-2-butanol is attached to a tertiary Carbon, meaning the reaction should occur via Sn1, a two-step reaction, and Cl should replace the OH group, to form a tertiary halide. HCl was added to 2-methyl-2-butanol and then several…

    and DSC analysis. The solubility revise in aqueous system showed an improvement within the solubility of conjugates. The dissolution studies showed an accurate acid–base catalysis prototype reliant on the pH of the medium. This indicated a fine chemical constancy in aqueous buffer solution of acidic medium and the comprehensive discharge performance was found in prodrug…

  • Atsuete Beets Experiment

    Results and Discussion A. Diffusion of selected plant pigments In conducting the diffusion of 4 different kinds of treatments (distilled water, distilled water placed in boiling bath, vegetable oil, heated vegetable oil), the researchers made use of the atsuete and sugar beets. The different kinds of treatments determined how the temperature will affect the color intensity of the atsuete and sugar beets. There were 4 test tubes used in each atsuete and sugar beets with each having a…

  • Tetrahydrocarbazole Synthesis Lab Report

    The heterocyclic compounds naming tetrahydrocarbazoles having the significant biological properties. The newly substituted tetrahydrocarbazole derivatives were prepared from substituted phenylhydrazine and cyclohexanone in glacial acetic acid under reflux. These intermediates on reaction with substituted aromatic acid chlorides in alkaline media finally converted to N-Substituted tetrahydrocarbazoles. Fifteen compounds are synthesized and charaterized by their melting point (MP), IR, NMR, MS…
