- The name polyols
refers to alcohols containing multiple hydroxyl groups.
- In polymer chemistry,
polyols are compounds with multiple hydroxyl functional groups available
for organic reactions.
- A sugar alcohol (also
known as a polyol, polyhydric alcohol, or polyalcohol) is a hydrogenated
form of carbohydrate, whose carbonyl group (aldehyde or ketone, reducing
sugar) has been reduced to a primary or secondary hydroxyl group.
- Polyols are
- Since “polyols” is
not a consumer friendly term, many nutritionists and health educators
refer to polyols as “sugar replacers” when communicating with consumers.
- Polyether polyols are
produced by the catalysed addition of epoxides, mainly propylene oxide
or ethylene oxide, to an initiator having active hydrogens.
- Natural materials
such as sugar, glycerin and sorbitol have been used for many years in
the production of polyols.
- New soy-based polyols
produced by enzymatic routes and having good reactivity with isocyanate
in polyurethane foam production.
- Production of polyols
by the yeastlike fungus Moniliella tomentosa could be increased by
growing the organism at constant low pH.
- Most polyether
polyols production involve the handling of hazardous air pollutants(HAP)
in two main areas: the polymerization reaction area and the polyol
- Polyether polyols
based on propylene oxide (PO) are produced by the base-catalyzed
reaction of propylene oxide with an initiator compound having active
- Soy epoxy polyols
with different OH contents were prepared through a one-step reaction
using the method of in situ performic acid generation.
- The composition of
polyester polyols can be derived from terephthalic acid (TPA) and
diethylene glycol (DEG).
Cobalt and Co80Ni20 metal particles were prepared by reduction of
acetate salts in a liquid polyol.
- Soy-based polyol used
in polyurethane applications are sustainable and renewable materials.
- Polyols are used to
react with isocyanates and form urethane functional groups in polyurethane
characterization and in vitro properties of UV curable polyester polyol
acrylates intended for tissue sealant applications.
- It is shown that
polyols, such as sorbitol and xylitol, markedly reduce the
dehydrochlorination rate and improve Congo Red values.
- The market potential
for bio-based polyol in USA is 700–900 million pounds/year, and the
global market potential for bio-based polyols is approximately 2.1-2.7
- A major producer was
seeking an 8 cents/lb ($176/tonne) polyether polyols increase for all
customers, to be implemented on all market segments and end-use
- According to BCC more
than one million tons of sorbitol liquid and crystalline are sold in the
US, Europe and Asia. All other polyols are relatively small in volume,
with sales ranging from 20,000 ton 200,000 tons.
