Acetone Reports Samples For Students

Re: A column to separate an Acetone-Methanol mixture

The objective of the project was to optimize the design of a column used to process a supply stream containing 35 percent acetone at 30oC. The optimized design should turn out a distillate product containing 0.75 mole fraction of acetone and 0.0010 fraction of bottoms acetone. The outcome of the experiment produced a distillate product containing 0.0079 molar fraction of acetone.

The molar fraction of acetone in the first inlet stream was determined to be 0.14 lbmol/min. Also, the total flow rate of the second inlet stream and the total gas flow rate were determined to be 61.84 lbmoles/min ...

Abstract
Reliable techniques to meet the needs of patients with peripheral nerve repair injuries need to be refined. One of the strategies often used is to create a nerve guidance channel or build a nerve conduit Silicone is has been found to work well as a conduit from an injury for regenerated axon cells if it does not contain foreign components. The cycle of the cleaning treatment was repeated until the Pentane-Acetone-Heat Procedure was successful and the plated cells survived for several weeks. The duration of the plating and cell count using the cleaned silicone lasted from May 3, 2013 to ...

Introduction and Literature Review

The value for a drug is significantly impacted by the dissolution rate, chemical stability and solubility of the drugs thereby impacting the pharmaceuticals efficiency as well. In the pharmaceutical industry multi-component crystals such as hydrates, solvates, co-crystals and salts have a major role during the design of new solids. Solid does not self-crystallize. It crystallizes in varied forms depicting random crystal properties. Various approaches are used to modify solids like Salting, Solvation, Hydration, and Polymorphism. Apart from these approaches, Co-Crystallization is a promising new approach to modifying solids (Nauha, ...

Lab Report on Aldehydes and Ketones Experiment

Lab Report on Aldehydes and Ketones Experiment

The current experiment aimed at learning properties of some of the common aldehydes and ketones, as well as, the chemical tests used to distinguish the different classes.
Both aldehydes and ketones have the same functional group known as carbonyl group C=O. In the aldehyde compounds, the carbonyl group is located at the end the structure with a general structure shown below (McNaught & Wilkinson, 1997).
The carbonyl carbon is, therefore, the first carbon of the carbon chain. On the other hand, the carbonyl group in ketones is located anywhere on the carbon ...

Introduction
The purpose of this lab was to find the amount and percentage of nickel present in an unknown compound using the "mole method." The unknown nickel compound was dissolved in water and treated with dimethylglyoxime and ammonia solutions to obtain the precipitate of known chemical composition (bis(dimethylglyoximo)nickel(II)), which then was weighed and using this data the amount and percentage of nickel in the initial compound were found. The insoluble Ni(DMG)2 complex is formed in two steps. First, the dimethylglyoxime reacts with hydroxide ion formed through the ammonia hydrolysis to produce dimethylglyoximate anion:
C4H8N2O2( ...

Abstract

The experiment conducted is a palladium catalyzed coupling of a terminal alkyne to 4-Iodonitrobenzene. 1.25 mL of 95% ethanol was added along with 93mg of 4-Iodonitrobenzene, 80mg piperazine hexahydrate and 4 mg CuI, in a 5mL clean and dry conical vial plus spinvane. 80 µL (density 0.898 g/mL) of tetrahydro-2-(2-propynyloxy)-2H-pyran was added to the solution through an automatic pipette. To this add 3 mg of Pd(OAc)2, refluxed and stirred under a water cooled condenser for half an hour until it turned dark brown. The reaction mixture was then poured into a clean and dry evaporating dish and heated gently with a ...

Question 1: Separation of mixtures

1. Extraction

This is a method of separation of two immiscible solvent phases. It is the best method for the separation of a mixture of Cyclohexanone and Acetone (miscible)

Reason:

Cyclohexanone is insoluble in water while Acetone is miscible with water. A mixture of the two compounds forms two distinct layers in water. Distillation cannot be used because the two compounds are highly flammable.

Procedure:

In this method of separation, water is added to the mixture. Acetone completely mixes with water while cyclohexanone does not. A funnel is then used to separate the two.

(Note: the colouration is ...

Component One

The Data Quality Objectives (DQO Process) is a planning process that has been developed by the United States Environmental Protection Agency. This particular planning process is used when environmental information or data is used to make a choice between two specific alternatives or to make a derivation of contamination estimate. The process is also used in the development of acceptance and performance criteria that find use in the clarification of study objectives, defining of appropriate data type and the specification of potential errors of decisions that are then used as the basis for the establishment of the quantity and the quality of ...
