Ethane-1 2-diol (ethylene glycol monoethylene glycol MEG) which is manufactured from ethene via epoxyethane is used to make polyester fibres resins and films although it is probably better known for its use as a coolant in cars It is miscible with water and it lowers the freezing point of water so it

The diols such as ethane-1 2-diol which are the products of the reaction with cold dilute potassium manganate(VII) are themselves quite easily oxidised by manganate(VII) ions That means that the reaction won't stop at this point unless the potassium manganate(VII) solution is very dilute very cold and preferably not under acidic conditions
