was also well known to alchemists of the Renaissance. Andreas Libavius (AD 1540–1600) distinguished the properties of vinegar from those of icelike (glacial) acetic acid obtained by dry distillation of copper acetate or similar heavy metal acetates. Numerous attempts to prepare glacial acetic acid by distillation of vinegar proved to be in vain‚ however. Lavoisier believed he could distinguish acetic acid from acetous acid‚ the hypothetical acid of vinegar‚ which he thought was converted into acetic

and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure ethanol. Introduction Fermentation is a metabolic process in which an organism converts a carbohydrate such as starch or sugar‚ into an alcohol or an acid. One particular alcohol‚ ethanol is the least toxic of the alcohols and as such‚ has

sample of cyclohexane and toluene using simple miniscale distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are acquired during the distillation process. It is expected that cyclohexane boils and distils before toluene. By gathering these measurements will allow us to determine refractive index of fractions collected. An Abbe refractometer will be used to accomplish this.

Heather Myers iLab‚ Week #6 CRUDE OIL DISTILLATION Introduction The purpose of this lab is to distill crude oil and learn how the chemical properties influence the temperature. The distillation of a substance is based on the boiling points. When the crude oil is brought to a boil‚ at 275°C‚ the gasoline and kerosene are distilled‚ but the lubricant remains part of the crude oil. Procedure 1. From the Equipment menu‚ select Distillation Equipment and obtain a Round Bottom Flask (100 ml). 2. Select

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

TESTING YOUR COMPREHENSION 1) Why are fossil fuels our most prevalent source of energy today? Why are they considered nonrenewable sources of energy? Today‚ the three main fossil fuels that are in demand are oil‚ coal and natural gas. These fossil fuels are prevalent because they are efficient to burn‚ ship‚ and store based on high energy content. Fossil fuels also provide for our daily needs such as transportation‚ heating‚ cooking and electricity. Based on our current rates of consumption‚ we
