This organic compound is highly toxic. It is also known as Ethane-1,2-diol or Monoethylene glycol. It has no smell and is viscous. It is colourless and has a sweet taste. It appears as a clear, colourless, liquid. It is widely used as an antifreeze and a raw material in the plastic industry. Ethylene Glycol is produced when ethylene oxide reacts with water.
Ethylene glycol has been the most abundantly produced diol because it is one of the monomers of polyethylene terephthalate. Ethylene glycol has been synthesized by the oxidation of ethylene with O2 to ethylene oxide and the subsequent hydration of ethylene oxide to ethylene glycol. Usually, ethylene is supplied from the thermal cracking of naptha from petroleum refining.
Ethylene glycol is a prominent member of the class of dihydroxy alcohols known as ethylene glycols, dihydric alcohols or diols. Ethylene glycol is prepared by the following methods.
By hydroxylation of ethylene. When the ethylene is treated with Baeyer’s reagent (cold dilute alkaline solution of potassium permanganate), hydroxylation takes place at both the carbon atoms.
Preparation of Ethylene Glycol From Ethylene
By hydrolysis of ethylene oxide. Ethylene oxide obtained after catalytic oxidation of ethylene is hydrolysed in the presence of dilute acid or base at high temperature to ethylene glycol.
Preparation of Ethylene Glycol From Ethylene Oxide.
Oxalic esters on reduction with sodium and alcohol give ethylene glycol.

In a Visual Basic macro, use the Visible property to hide or unhide a sheet. You can set the Visible property to True, False, or xlVeryHidden. True and False have the same effect as using the Unhide or Hide menu commands. The xlVeryHidden argument hides the sheet and also keeps the Unhide dialog box from displaying it.
