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. Now Southwest will offer an additional option to upgrade their position with the open seating at the board gate. The airline continues: Now they have one more way to be among the first to board.
But Southwest calculates the points needed by multiplying the base fare (not the total fare) by 70. That means that on a points booking, you are NOT being charged for all of the additional taxes and fees (except for the security fee of $2.50). The points needed for this booking are $72.56 x 70 = 5,079 Southwest points. But youâre getting a value of $89 â $2.50 = $86.50 for the fare. And ($86.50 cost of flight / 5,079 Southwest points) = ~1.7 cents per point! So Southwest points are still worth more than the advertised value of ~1.43 cents per point!
