Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound primarily used as a raw material in the manufacture of polyester fibers and fabric industry, and polyethylene terephthalate resins (PET) used in bottling.thylene glycol is used as a protecting group for carbonyl groups in organic synthesis. Treating a ketone or aldehyde with ethylene glycol in the presence of an acid catalyst (e.g., p-toluenesulfonic acid; BF3â¢Et2O) gives the corresponding a 1,3-dioxolane, which is resistant to bases and other nucleophiles.
Southwest to charge $40 to upgrade to an earlier âAâ boarding pass on the day of flight. Southwest Airlines (Dallas) customers LUV the coveted âAâ boarding group according to the airline.

When canceling online, you will receive the two options below âHold for future useâ and âRequest a refund of the refundable balanceâ. The âHold for future useâ is automatically selected, so make sure to change that option. Southwest now requires that you cancel or change a ticket prior to the flight departing. This is a new-ish rule for Southwest and you must cancel/change at least 10 minutes prior to take off. If you donât Southwest will not credit you back the amount/points if you miss your flight. I still think this is a VERY reasonable policy as changes/cancelations can still take place day of departure for no fee!
