Notes, Exercises, Videos, Tests and Things to Remember on Glycerol and Ether
Please scroll down to get to the study materials.
Ether is a compound which consists of an oxygen atom linked with two alkyl or hydrocarbon group by a single bond. Generally, diethyl ether is simply called ether. Some other ether are diethyl ether (CH3-O-CH3), ethyl methyl ether (CH3-O-C2H5).
The glycerol is one of the trihydric alcohols.
The physical properties of glycerol are:
i. It is colorless, viscous and hygroscopic liquid with the sweet taste.
ii. It is soluble in water but insoluble in ether.
The two uses of glycerol are:
i. It is used medicinally to soften the skin of the body.
ii. It is used to make good quality soaps and cosmetics.
Glycerol was accidentally discovered in 1779 by K. W. Scheel when he was heating a mixture of olive oil and lead monoxide.
The IUPAC name for glycerol is 1,2,3-propanetriol. and its formula is CH2OHCHOHCH2OH
Glycerine is used in the manufacture of papers as a plasticizer/humectant and lubricant. In addition to the softening effect of retained moisture, it also reduces shrinkage.
Solvent: Ethers are quite unreactive and therefore are desirable solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. In addition, vapours of certain ethers are used as insecticides and fumigants for top soil.
Sedative :Ethers also play an important role in pharmacology and medicine, especially for use of anaesthetics.
Industrial Purposes: Ethoxyethane (ethyl ether) is quite volatile and therefore used as a starter fluid for diesel engines and gasoline engines in cold weather.
The molecular formula of glycerol: (CH2OH-CHOH- CH2OH).
Molecular formula of diethyl ether is C2H5-O-C2H5
The two uses of ether or diethyl ether are
The uses of glycerol are:
