The glycol removes water from the natural gas by physical absorption and is carried out the bottom of the column. Upon exiting the absorber the glycol stream is often referred to as rich glycol . The dry natural gas leaves the top of the absorption column and is fed either to a pipeline system or to a gas plant. Glycol absorbers can be either tray columns or packed columns.

Polypropylene glycol or polypropylene oxide is the polymer of propylene glycol . Chemically it is a polyether . The term polypropylene glycol or PPG is reserved for low to medium range molar mass polymer when the nature of the end group , which is usually a hydroxyl group, still matters. The term oxide is used for high molar mass polymer when end groups no longer affect polymer properties. In 2003, 60 of the annual production of propylene oxide of 6.6× 10 sup 6 sup tonne s was converted into the polymer. ref A Highly Active, Isospecific Cobalt Catalyst for Propylene Oxide Polymerization Kathryn L.

Glycol cleavage is a specific type of organic chemistry oxidation . The carbon carbon bond in a vicinal chemistry vicinal diol glycol is cleaved and replaced with two carbon oxygen double bonds. Depending on the substitution pattern in the diol, either ketone s or aldehyde s may be formed. Glycol cleavage is an important reaction in the laboratory because it is useful for determining the structures of sugars. After cleavage takes place the ketone and aldehyde fragments can be inspected and the location of the former hydroxyl groups ascertained. ref Wade, L. G. Organic Chemistry , 6th ed.., Prentice Hall, Upper Saddle River, New Jersey, 2005 pp 358 361, pp 489 490. ISBN 0131478826 ref Reagents Periodic acid HIO sub 4 sub and lead IV acetate lead tetraacetate Pb OAc sub 4 sub are the most common reagents used for glycol cleavage.

Glycol nucleic acid GNA is a polymer similar to DNA or RNA but differing in the composition of its backbone . GNA is not known to occur naturally they are oligonucleotide synthesis synthesized chemically . The 2,3 dihydroxypropylnucleoside analogues were first prepared by Ueda et al. 1971 . Soon thereafter it was shown that phosphate linked oligomers of the analogues do in fact exhibit hypochromicity in the presence of RNA and DNA in solution Seita et al. 1972 . The preparation of the polymers was later described by Cook et al. 1995, 1999 and Acevedo and Andrews 1996 . The GNA GNA self pairing described by Zhang and Meggers is however novel, and the specificity of interaction well demonstrated. DNA and RNA have a deoxyribose and ribose sugar backbone, respectively, whereas GNA s backbone is composed of repeating glycol units linked by phosphodiester bond s. The glycol unit has just three carbon atoms and still shows Watson Crick base pairing. Interestingly, the Watson Crick base pairing is much more stable in GNA than its natural counterparts DNA and RNA as it requires a high temperature to melt a duplex of GNA. It is possibly the simplest of the nucleic acids, so making it a hypothetical precursor to RNA.
