Subject: Re: oxyalkylated alcohols
You are basically talking about a
surface active agent
surfactant
detergent
soap
dispersant
or any of the many names that are
used. They
are
mainly added to commercial product for
solubility
and mixing reasons, to keep the
ingredients of
the
product in one phase. If used
directly, they
can
clean fabric, but usually in a product
those
are
the uses. You can even find them
used as
lubricants.
They basically make water a better
solvent for more
organic materials.
They are not benign in the environment
and in
textiles, we
have to worry about removing them from
wastewater
streams
before discharge.
This book has some of the structures
that can be
used (page 5).
also this one (page 46)

Subject: [DCHAS-L] oxyalkylated
alcohols
OK, professors, I give up on this
class of
chemicals. I am seeing MSDSs on everything from detergents to
pesticides
to photosensitive chemical developers listing this category of
chemical.
Of course, they are hiding an individual chemical by listing a whole
class
probably by a synonym, but I'm even confused about what the generic
structure
looks like.
I know what an alkyl group is, so let's call it
R-
I
know what an alcohol looks like, so lets use ethanol.
Oxy means
an
0=
But how do I fit these together into what they are talking
about?
Thanks.
