Abstract
FATTY TETRAAMINES ARE USED ALONE OR IN ADMIXTURE WITH OTHER SPECIFIED COMPOUNDS AS BIOCIDES FOR VARIOUS PURPOSES.
Description
United States Patent 015cc ABSTRACT OF THE DISCLOSURE Fatty tetraamines are used alone or in admixture with other specified compounds as biocides for various pur poses.
This invention relates to fatty tetraamines and their use as biocides. More particularly, this invention relates to the use of N"',N"-di-(3-aminopropyl) aminofattyamines as biocides.
Much effort has been expended to devise a biocide which is all-purpose. Usually, the biocide is useful against one or more aerobes or anaerobes, but never all of them.
With the recent advent of difunctional fatty compounds, particularly the dicarboxylic acids, chemists and bacteriologists have come closer to such a desire. Copending patent applications, Ser. No. 41,014 filed Nov. 9, 1964, now US. Pat. 3,448,374 issued Dec. 24, 1968, and Ser. No. 398,437 filed Sept. 22, 1964 now US. Pat. 3,354,213 issued Nov. 21, 1967, respectively, are typical examples of such recent work.
Accordingly, an object of this invention is to provide diamino fatty amines which are useful as biocides.
Another object is to provide bactericides which are useful against anaerobes.
Still another object is to provide bactericides which are useful for aerobes.
A further object is to provide novel sulfate reducer bactericides. 40
Other objects of the invention will in part be obvious and will in part appear hereinafter.
It has now been found that fatty tetraamines of the following formula may be used as biocides for anaerobes and aerobes:

or mixtures thereof such as derivable from natural fats and oils such as tallow, soybean oil and coconut oil.
The invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others, and the compound possessing the features, properties, and the relation of elements, which are exemplified in the following detailed disclosure, and the scope of the invention will be indicated in the claims.
Reference is now made to the following examples which illustrate the invention in detail:
EXAMPLE I A number of known biocides and the N"',N"-di-(3- aminopropyl)aminofattyamines are compared as to their algaecidal activity against chlamydomonas (C in Table 1 which follows( and scenedesmus (S). All results shown (expressed in ppm.) are of replicate testing with the highest dilution exhibiting growth and the lowest dilution inhibiting growth being reported as a range. All tests are run at room temperature, the chemical named being tested on an as is basis.

EXAMPLE II A common contaminant of oil injection systems is D- desulfricans, which is an anaerobic bacteria. In the Table 2 which follows, the named diamines and their salts (on an as-is basis) are compared to the named tetraamines and the results are expressed in a lower and upper effective range in a p.p.m. basis. The tests are run at 3132 C. for twenty-eight days in a 3.0% NaCl based media.

The chemical compounds are added to the exposure bottles at appropriate doses for 1 or 2 hours as indicated. After the exposure time, a 1 ml. sample from each bottle is transferred to Diicos sterile nutrient broth bottles and incubated at 37 C. for 78 days.

Exposure bottles containing either sterile distilled water or sterile 3% synthetic brine are inoculated with four day old cultures of D. desuljuricmzs in an anaerobic condition and exposed to the chemical compounds at appropriate doses for 1 or 2 hours as indicated. After the exposure time, a 1 ml. sample from each bottle is transferred to an anaerobic sulfate-reducing medium (API broth) and incubated at 37 C. for -20 days. Growth of sulfate-reducers in the bottles is indicated by blackening of the medium (red to black iron sulfide).
EXAMPLE IV N",N"-di-(3 aminopropylaminomethylstearylamine (DMSA) and homologs are very effective in controlling aerobic bacteria which are common contaminants in oil wells, cooling towers and swimming pools, as evidenced by the data of Table 4. All tests are run for 24 hours at 37 C.
