APPLICATIONS |
||
|
Glycol: any of a
class of organic chemicals characterized by having separate two hydroxyl (-OH)
groups, contribute to high water solubility, hygroscopicity and reactivity with
many organic compounds, on usually linear and aliphatic carbon chain. The
general formula is CnH2n(OH)2 or
(CH2)n(OH)2. The wider meaning
names include diols, dihydric alcohols, and dihydroxy alcohols. Polyethylene
glycols and polypropylene glycols are sometimes called polyglycols which are
derived by polymerization of ethylene oxide and propylene oxide respectively.
Polyethylene glycols are water-soluble at all molecular weights, but
polypropylene glycols become increasingly less water-soluble at high molecular
weights. Mono-, di- and tripropylene glycol, the first three members of a
homologous series of propylene glycol, are completely water and ethanol soluble;
miscible with most organic solvents including acetone, chloroform and some
essential oils; soluble in 12 parts of ether. Propylene glycol is an odorless
and colorless liquid; boiling point 188 C, freezing point -39 C. Propylene
glycol is prepared by hydrolysis of propylene oxide. Large amount of propylene
glycol is used in the plastics industry for the manufacture of polyester fibers
and alkyd resins. It is used as a main ingredient in automobile antifreeze and
engine-cooling liquids and in brake and hydraulic fluids due to its useful
properties of low freezing point, involatility and low corrosive activity. It is
used in the preparation of body-care surfactants. Propylene glycol is replacing
ethylene glycol and ethanol as it is less toxic than ethylene glycol. Propylene
glycol is described as a "generally recognized as safe for use in food,
cosmetics, and medicines" by FDA. Propylene glycol USP grade is used as a
non-toxic antifreeze in breweries and dairies. It is used as a humectant in
foods and cosmetics. It is used as a solvent for colouring or flavouring agents
as well as in many oral, injectable or topical pharmaceuticals. Its
antibacterial property is applied in the preparation of sanitizing
lotions.
Methoxypropanol's application is similar with propylene glycol as a low volatile solvent, but better dissolving is expected. Methoxypropanol is used to improve dissolving power, drying time, and flow. It is also known to be used as an intermediate for the synthesis of proton pump inhibitor (Rabeprazole Sodium). |
