Synthesis of Phenacetin from para-Acetamidophenol

Experimental: Sodium metal was patted dry to remove any oil and was cat into small pieces. A dry 100cm3 round bottom flask was placed on a cork ring, on a balance and tarred sodium metal (0.6g) was placed into the flask. The flask was then attached to the dry reflux condenser and industrial methylated spirits (IMS, 15cm3) was added. Once all of the sodium has dissolved the solution was cooled to room temperature and the para-acetamidophenol (3.5g) was added. Ethyl iodine (3.0cm3) was slowly introduced to the mixture through the top of the condenser and the resulting in the mixture was boiled at reflux temperature for 20 minutes and was placed in a rotary evaporator to remove any excess solvent….

Biology Properties of water lab

Procedure The independent variables for this experiment are the types of water solutions used. The dependent variable is the boiling temperature of the water which will be measured by a thermometer. The control group is the water. The constants are the Stove top and amount of water used in each solution the starting temperature of the water and the Pot. 1. Pour 2 cups of water in the pot add 1 tablespoon of sugar then stir it up until all sugar is dissolved. 2. Turn on the stove, set the stove to it’s highest setting, place the pot on and time it with a stopwatch. Record the time and temperature of the solution as soon as it begins to boil. Record…

Water short essay

‘Water’ is one of the natures precious gifts to mankind. All living things consist mostly of water eg. the human body is of two thirds of water. It is clear, colourless liquid that appears blue when viewed through a thickness of 20 ft. The colour reflects not only from physical causes but also from suspended impurities. The freezing point of water is 0degree centigrade and its boiling point is 100 degree centigrade. Water is the most essential component of life and is vital for sustenance. The importance of water in our diet is apparent as it helps the body to perform specific metabolic tasks and regulates our body temperature, moreover water is unique as it’s density is similar to that…

Audible Thermometer

The objective of our project was to build a Independent audible thermometer, which can speak the body temperature of a person. Our original goal was to build both software and hardware setup of the audible thermometer. We have already finished the software setup and we are currently working on the hardware, which we couldn’t complete because the budget was pretty heavy for us. So, we’ve built a setup which can speak a person’s body temperature using the sensor and a computer. CHAPTER 2 This chapter should give the essential back-ground Theory on the subject of the project and essential derivations or the like. CHAPTER 3 This chapter should normally cover design / programming methodologies or other approaches suggested in the…
