Alkoxylates and the use thereof
Description
The present invention relates to the use of an alkoxylate based on 2-
propylheptylamine which
has been alkoxylated with ethylene oxide, propylene oxide, butylene oxide,
pentylene oxide,
styrene oxide, cyclohexylene oxide and/or decylene oxide, and/or its
quaternized derivative in
cleaning compositions, as emulsifier, in the manufacture of fibers, for
leather treatment, in
printing inks, in formulations for construction chemistry or in formulations
for flotation.
Furthermore, the present invention relates to a mixture comprising at least
one of the specified
alkoxylates and also at least one surface-active substance and use thereof.
Compositions based on alkoxylated alkylamines are already known from the prior
art.
WO 2009/004044 Al discloses asymmetrically alkoxylated alkylamines which can
be used as
surfactants. The asymmetrically alkoxylated alkylamines are based on
corresponding
alkylamines having one to four carbon atoms, or benzylamines. 1 to 30 units of
ethylene oxide,
propylene oxide and/or butylene oxide are added by alkoxylation. WO
2009/004044 Al
furthermore discloses that these compounds can be used in herbicidally
effective compositions.
US 5,668,085 discloses surface-active compounds comprising alkoxylated amines.
These
alkoxylates are based on alkylamines or alkenylamines having 8 to 22 carbon
atoms and are
obtained by alkoxylation of these amines with ethylene oxide or propylene
oxide. In total, 2 to 8
units of the specified alkylene oxides are present in the compounds according
to US 5,668,085.
It was therefore an object of the present invention to provide an alkoxylate
which can be used in
various technical applications and produces advantageous results. Furthermore,
it is an object
of the present invention that corresponding alkoxylates are used which have
lower toxicity,
especially lower aquatoxicity.
These objects are achieved according to the invention through the use of an
alkoxylate of the
general formula (A)

A process for the preparation of the compounds of the general formula (Q) or

for example, the alkoxylation of 2-propylheptylamine with ethylene oxide,

butylene oxide or a mixture thereof. The preparation of 2-propylheptylamine is
generally known,
for example by reacting ammonia with 2-propylheptanol as described in US
5,808,158. The
alkoxylation can be catalyzed by strong bases, such as alkali metal hydroxides
and alkaline
earth hydroxides, Bronsted acids or Lewis acids, such as AICI3, BF3. For
alcohol alkoxylates
with a narrow distribution it is possible to use catalysts such as
hydrotalcite or DMC. The
alkoxylation preferably takes place at temperatures in the range from about 80
to 250 C,
preferably about 100 to 220 C. The pressure is preferably between ambient
pressure and 600
bar. If desired, the alkylene oxide can comprise an inert gas admixture, e.g.
of about 5 to 60%.
The quaternized derivative (AQ) of the amine alkoxylate (A) can be prepared in
a further
reaction step from the amine alkoxylate (A) by quaternization. To insert the
radical R3 into the
amine alkoxylate (A), it can be reacted for example with an alkylating reagent
such as methyl
chloride, dimethyl sulfate or butyl chloride. To insert an oxygen anion into
the amine alkoxylate
(A), it can be oxidized, for example by reacting the amino group with hydrogen
peroxide,
peracids such as meta-chloroperbenzoic acid or peracetic acid or
peroxomonosulfuric acid. The
preparation of the quaternized derivatives (AQ) where R3 = H can take place by
simple
protonation of starting compounds of the structure (A). The preparation of the
quaternized
derivatives (AQ) where R3 = OH can take place by simple protonation of
starting compounds
(AQ) where R3 = oxygen anion. For the protonation, suitable acids are organic
acids, e.g. C, to
C20 carboxylic acids, for example the carboxylic acids or inorganic acids
specified as component
(C) of the mixture according to the invention, e.g. hydrochloric acid,
phosphoric acid or sulfuric
acid. The protonation can be carried out in a separate synthesis step so that
the quaternized
PF 70102 CA 02801643 2012-12-05
6
derivative (AQ) can be isolated. It is also possible to carry out the
protonation by mixing the
starting compounds with one or more acids in the mixture according to the
invention.

The present invention also relates to a process for the preparation of the
specified mixtures
according to the invention by combining the individual components in the
respective amounts.
Devices for this process according to the invention are known to the person
skilled in the art.
The process according to the invention can be carried out at room temperature
or elevated
temperature.
The present invention also relates to the use of the mixture according to the
invention in
cleaning compositions, as rust remover, as emulsifier, during the manufacture
of fibers, for
leather treatment, in printing inks, in formulations for construction
chemistry or in formulations
for flotation. As regards these uses, that stated in relation to the use of
the compounds of the
general formula (A) and (AQ) is applicable.
The present invention is described in more detail by the examples below.
Examples:
Example 1 (comparative example):
A car washing formulation known from the prior art is used which has the
following composition:
10% by weight of benzenesulfonic acid, C10-13-alkyl derivative, sodium salt in
water (50%)
20% by weight of oleylamine ethoxylate with 12 EO,
12.5% by weight of lauryl/mistryl trimethylammonium methosulfate in water (30%
strength) and
57.5% by weight of demineralized water.
Example 2 (according to the invention):
In the formulation according to example 1, oleylamine ethoxylate having 12 EO
is replaced by
an equivalent amount of 2-propylheptylamine-(EO),o.

Results:
During the preparation of the formulations, it can be observed that the 2-
propylheptylamine
ethoxylate according to the invention can be incorporated into the formulation
considerably
better. Oleylamine ethoxylate having 12 EO needs longer until it has dissolved
in the
formulation.
Furthermore, the cleaning performance of the formulations according to example
1 and
example 2 is determined in accordance with Sheen (multitrack wiping device).
The cleaning
performance is the same for both formulations; the formulation according to
example 2 foams
more, but after rinsing the test plates, both are assessed the same.
In summary, it can be stated that the formulation according to the invention
as in example 2
exhibits an at least equally good cleaning performance as the formulation
known from the prior
art as in example 1. Furthermore, the formulation according to the invention
exhibits better
formulatability without loss of cleaning performance.
