The following amino compounds of formulas (2)
and (3) may be used as starting compounds to produce the
ester amines:

where Po is -(O-CH2-CH) and EO is -(O-CH2-CH2)-,
a is 0 to 20,
c is 0 to 20, and
a, c, b and R6 have the meanings given above,
R6 being more particularly an alkyl group having from 1
to 5 carbon atoms, and c being 0.
These products are produced commercially and
are generally obtained by known processes by reacting
polyoxyalkylene alcohols with ammonia under pressure.
Polyoxyalkylene alcohols are typically prepared
by the addition of an alkylene oxide, especially
propylene oxide, ethylene oxide or a mixture of the two,
by a conventional method to a compound which contains one
or more active hydrogen atoms, or by polymerization of
alkylene oxides.
Illustrative of compounds containing one or
more active hydrogen atoms are monohydric alcohols such
as ethanol, isopropanol, butanol, lauryl alcohol, stearyl
alcohol, and particularly methanol, or glycols such as
ethylene glycol, propylene glycol, diethylene glycol,
glycerol, trimethylolpropane, pentaerythritol, sorbitol,
polyglycerol, and polyvinyl alcohols.
The polyoxyalkylene alcohols have molecular
weights ranging from about 100 to 10,000, and preferably
from about 150 to 5,000, and most preferably from about
150 to 2,000.
The further reaction to give amines is carried
out typically by conventional methods through aminolysis
of the free hydroxyl groups or their esters, particularly
the sulfates. In the case of higher alcohols, the -OH
group is exchanged for the amino group by means of
homogeneous catalysis, and especially of heterogeneous
2510:CMs2510
204423~
catalysis on solid catalysts. For this purpose, at least
two methods in particular are available. One employs
dehydrating catalysts, and the other, catalysts having
hydrogenating/dehydrogenating action.
Alumina with up to about 20% of chromic oxide,
stannous oxide, zinc oxide or ferric oxide is used as
catalyst.
Alumina deposited on silica gel or activated
charcoal is suitable for the conversion at atmospheric
pressure of higher fatty alcohols to fatty amines, for
example. (See British patent 384,714 and U. S. patents
2,017,051 and 2,078,922.) Acids of aluminum phosphate,
or phosphoric acids, either as such or on supports such
as silica gel or diatomaceous earth (U. S. patent
2,073,671), are frequently used in production at standard
or elevated pressure (U.S. patent 2,043,965). The
operating temperatures range from 200 to 600C, depending
on the catalyst. The literature is replete with data on
the effect of temperature and pressure, on an excess of
ammonium, and on the necessary residence times. (See,
for example, Houben-Weyl, Methoden der organischen
Chemie, Georg Thieme Verlag, Stuttgart 1957, vol. II/1,
p. 108 et seq.)
In accordance with the invention, the following
compounds are preferred:
Of formula (2),
a + c = 2 - 6 (I)
b = 0
or
a + c = 2 - 3 (II)
b = 6 - 9
2510:CMS2510
20~4234
and of formula (3),
a + c = 6 - 10 ~III)
b = 1 - 2
R6 = -CH3
The compounds of formulas (2) and t3) are then
alkoxylated, and preferably ethoxylated or propoxylated,
typically by conventional methods. The usual procedure
is to react the amines in a pressurized reactor at
between 120 and 160 C, optionally in the presence of
basic, and more particularly alkaline, catalysts at from
1 to 4 bars with a quantity of alkylene oxide correspond-
ing to the desired degree of alkoxylation, ethylene oxide
and propylene oxide or mixtures thereof being preferred
in accordance with the invention.
What is obtained are compounds of the general
formulas

R6, EO and PO, all have the same meaning as above and
d + e + f ~ g = 2-12, and
R3 R4 R7 and R8 = H
and, independently of each other, may be H or CH3.
Preferred compounds of formula (4) are
compounds where
d + e + f + g = 4-6, and (IV)
R3, R4, R7 and R8 = H
and preferred compounds of formula (5) are compounds
where
d + e = 2-3 (V)

The subsequent esterification of the compounds
(4) or (5) with carbonic acids or derivatives thereof
gives compounds of the general formulas

are, independently of one another, hydrogen, an alkyl
group having from 1 to 5 carbon atoms, or a -C-R11 group,
S 11
R11 being a hydrocarbon group, optionally branched, and
optionally containing multiple bonds or hydroxyl groups,
having from 6 to 21, and preferably from 7 to 17, carbon
atoms, with the proviso that at least one of the groups
Rl, R2, R9 and R10 must be a -C-R11 group.
15 Fatty acids which are suitable for
esterification or transesterification are the monobasic
synthetic fatty acids known and commonly used in this
field, and especially the fatty acids based on natural
plant and animal oils having from 6 to 22, and more
particularly from 8 to 18, carbon atoms, such as those
derived from coconut oil, palm oil, tallow, and castor
oil. These may be used as glycerides, as esters with
short-chain alcohols, or as free acids.
Their esterification or transesterification is
carried out by the known method.
The alkanolamines are thus reacted at from 160
to 240C with a quantity of fatty acid or fatty acid
ester corresponding to the desired degree of
esterification, optionally in the presence of a catalyst,
and the water of reaction or the alcohol is continuously
distilled off, a vacuum being applied if necessary to
complete the reaction.
Preferred compounds of formula (6) are
substances where
2510:CMs2510

R11 being C17H35, and preferred compounds of formula (7),
are where
R1 = H
R2 = C-R11 (VII)

R11 being C17H35.
The quaternization or the preparation of the
salts of the compounds of formulas (6) and (7) typically
are carried out by methods known in this field and yields
the inventive ester amine quaternary ammonium or ester
amine salts of the general formula (1), where R12 and R13
have the meanings indicated, k and 1 are greater than
zero, and k + 1 preferably has values between 0.5 and 2.
As a general rule, the salts are prepared by
adding the acids, optionally as aqueous or alcoholic
solutions, in a quantity corresponding to the desired
degree of salt formation at 20-80C with vigorous
stirring, and optionally with cooling, in portions to the
poly(oxyalkylene)alkanolamine esters introduced as
initial charge. The quaternization is carried out by one
of the generally known methods, the poly(oxyalkylene)-
alkanolamine esters being heated to 40-80C, optionally
with the concurrent use of a solvent, and reacted in
portions with the quaternizing agent in a quantity corre-
sponding to the desired degree of quaternization.

polyepoxies, which find use as flexible coatings, molded
articles, sealing compounds and fiber-reinforced
composite materials.
2510:CMS2510
20~4234
They are also of advantaqe in the formulation
of emulsifiers for use in agriculture, metalworking, and
to some extent in cosmetics.
The inventive compounds of the general formula
(1) with k + 1 > 0 find use especially as antimicrobial
agents. They are suitable for use as preservatives or
disinfectants for all kinds of commercial products used
in crop protection, agriculture and cosmetics.
They further lend themselves to the
preservation of glues, surface coatings or paints based
on organic vehicles. They can also be used as wood
preservatives.
By combining the compounds of the general
formula (1) with surface-active substances, washing and
cleaning agents having antibacterial action are obtained
which can be used as antimicrobial textile finishes.
The analytical methods used in the examples
which follow are those commonly employed in this field.
1 Total amine value and tertiary amine value
.
The total amine value gives the number of
milligrams of potassium hydroxide equivalent to the total
amine basicity of 1 gram of the amino compound (mg
KOH/g). The tertiary amine value gives the number of
milligrams of potassium hydroxide equivalent to the
tertiary amine basicity of 1 gram of the amino compound.
The values are determined by A.O.C.S. Official
Nethod Tf 2a - 64.
2. Sa~onification value
The saponification value is a measure of the
free and combined acids in fats and commercial fatty
acids. It gives the number of milligrams of potassium
hydroxide required for the complete saponification of 1
gram of fat or commercial fatty acid.
2510:CMS2510
204~234
The values are determined by the unit methods
of Deutsche Gesellschaft fur Fettchemie (DGF) (German
Society for Fat Chemistry), DGF C-V3.
3. Hydroxyl value
The hydroxy value is used to determine the
hydroxyl-group content and gives the number of milligrams
of potassium hydroxide required to neutralize the acetic
acid consumed by 1 gram of fat in acetylation (mg KOHtg).
The values are determined by DGF unit method
C-V17a.
4. Acid value
The acid value is a measure of the free-acid
content of a fat or of commercial fatty acids and gives
the milligrams of potassium hydroxide required to
neutralize 1 gram of substance.
The values are determined by DGF unit method
C-V4.
5. Content of cation-active substance. Cat S03
This method is used to determine the content of
cation-active substances. Cation-active substances here
are short- and long-chained compounds containing primary,
secondary and tertiary amino groups or ammonium groups.
The content is expressed as S03 per 100 g of the substance
being tested.
The content is determined by two-phase
titration in conformity with IS0 standards 2871-1 and
2871-2 (1988 edition).
