| Copy ETHYLENE GLYCOL General Properties: A clear colourless syrupy liquid possessing a sweet taste. As it is colourless, odourless, non-toxic and non-volatile, is easily mixed and has a pleasant taste, the compound is used in the manufacture of flavouring extracts. Specific Gravity: Is about 1.125, being about intermediate between water and glycerol. Boiling Point: About 197°C. Freezing Point: -12°C. Viscosity: Ethylene Glycol, like glycerine, is very hygroscopic. It is more viscous than water and less so than glycerine. Solubility & Inflammability: Ethylene Glycol is miscible in all proportions with water, glycerine, ethyl, methyl or amyl alcohol, acetone, glacial acetic acid, pyridine and furfuraldehyde. It is not miscible with benzene, toluene, xylene, chlorbenzene, chloroform, carbon tetrachloride, carbon bisulphide or ether. Ethylene Glycol is non-inflammable. Toxicity: No pathological symptoms were evident when Ethylene Glycol was administered in moderate doses to rabbits. Germicidal Value: As a preservative against bacterial yeast or mould growth, Ethylene Glycol shows a close approach to ethyl alcohol and is superior to glycerol. The large scale production of Ethylene Glycol has only become an economic proposition during the past few years. It is becoming increasingly important as a solvent, an anti-freezing compound and in the manufacture of Glycol dinitrate in dynamite etc. General speaking, it may be used for most purposes to replace glycerine. | ||
