Description

Biodegradable Compositions for Hydrocarbon and Fatty Oils

Eliminating fatty acids such as hydrocarbon waste and metal salts by biological degradation causes problems because natural biodegradation is too slow.

It is well known that in order to promote biodegradation of hydrocarbons or fats against microorganisms, in addition to the carbon supplied as products to be removed, nitrogen and phosphorus resources that cause the growth and development of microorganisms must be supplied to the microorganisms.

Biodegradation, eg in fermenters or breweries, in a closed environment is sufficient using aqueous culture media containing various nutrients in solution or suspension. On the other hand, studies show that in highly diluted media such as spillage and wastes in seas and rivers, nitrogen and phosphorus supplying materials must bind to hydrocarbon molecules and form emulsions with them. If not, the substances are actually diluted in water to their natural content so that their decomposition rate is similar to the natural biodegradation rate. Thus, the material used to enhance hydrocarbon biodegradation should be able to form an aqueous emulsion, whose Emilon must contain molecules of the material to be biodegraded and to supply nitrogen and phosphorus.

It is also necessary to have a detergent powder to clean the contaminated surfaces as the products are scavenged and decomposed into a composition formed by substances comprising nitrogen and / or phosphorus. Finally, the composition should not be detoxified to fauna or flora. Compositions made with hydrocarbons and fats that can biodegrade fats include aliphatic amides, carboxylic acid esters of aliphatic amides, and ammonium salts of carboxylic acids: phospho-amino lipids and petroleum solvents without benzene components. Configure. Generally, the composition consists of 20-30% by weight of aliphatic amide or aliphatic amide carboxylic acid, 2.5-6% by weight of aliphatic carboxylic acid ammonium salt, 2.5-5% by weight of phospho-amino lipid and 55% -75% by weight Contains petroleum solvent without% benzene fraction.

The composition according to the invention reacts an excess of carboxylic acid with a primary or secondary aliphatic amine, or primary or secondary amino-alcohol, neutralizes the mixture with ammonia to bring the pH to about 7, After addition, petroleum solvent from which benzene was removed is added and manufactured. The amines are, for example, monoethylamine, diethylamine, monomethylamine, dimethylamine, dodecylamine, isopropylamine, normal butylamine, di-normal-butylamine, monoamylamine, di-normal-amyl Amine or di-iso-amylamine.

Suitable amino-alcohols such as monoethanolamine, diethanolamine, amino-furopanolamine and aminobutanol can be used.

Carboxylic acids are preferred fatty acids that are liquid at ambient temperature, such as acetic acid, propionic acid, normal-butyl acid, hexanoic acid, caprylic acid, ethyl-2-hexanoic acid, oleic acid, capric acid or linoleic acid or lactic acid. Hydroxy acids or ricinoleic acid, and the like. Phosphorus-amino fats are generally lecithin.

Sodium solvents are white spirit normal-hexane normal-heptane, normal-octane, petroleum etherbenzene in solvents or mixtures thereof without benzene fraction.

In the composition of the invention the amide, in particular the aliphatic ester, acts as a detergent whose detergent capacity will be greater than that of the corresponding amines due to the presence of carbonyl groups, which also supply a portion of the necessary nitrogen. Because of the two lipophilic and hydrophilic groups, the amide guarantees the stability of the Emilon. Ammonium salts form a nitrogen source and lecithin provides the necessary phosphorus.

The present invention is explained in detail by the following examples.

Unless indicated otherwise in the examples, parts means parts by weight.

Example 1

7.5 parts of mono ethanolamine and 36 minutes of 2-ethylhexanoic acid are stirred, mixed, neutralized with ammonia and brought to pH 7 of the mixture. 5 parts lecithin and 102 parts white spirit are added to a 46 parts mixture (corresponding to 40 parts 2-ethylhexane, ethanolamide-2-ethyl hexanoate and 6 parts by weight of ammonium-2-ethylhexanoate). The composition is used to treat hydrocarbon sheets which float in the aquarium constituting the softener, which amounts to 15-20 parts per 100 parts of hydrocarbon.

Emil John rises in the upper layers of the aquarium. The flora and fauna of the aquarium do not show adverse effects due to the presence of Emilon, which is gradually disappearing. Gas chromatography shows complete biodegradation within 6 weeks.

Example 2

After stirring and mixing 7.5 parts of monoethanolamine and 18 parts of 2-ethyl-hexanoic acid, 35 parts of oleic acid are added thereto, and ammonia is added to neutralize to pH 7.

In this way, ethanol amide-2-ethyl-hexanooleate and ammonium oleate are obtained. Ligroin (or petroleum ether) without 18% lecithin and 250% benzene fraction is added to this mixture. The resulting composition is used to accumulate for a long time and to wipe the soil contaminated with oxidized No. 2 Huell. Washes containing Emilon were recovered and their toxicity was demonstrated for their flora and fauna and their biodegradability.

Traces of hydrogen carbohydrate were all removed from the bottom.

Example 3

9 parts of diesel was mixed with 21.5 parts of capric acid and the whole mixture was neutralized with ammonia. Mixtures of capricdiethylamide and ammonium caproate were mixed with lecithin and high spirits to give a composition containing 22% capric diethylamide, 4.5% ammonium caproate, 3.5% lecithin, 70% white spirit. The composition is diluted 5-6 times its weight with water and diluted and neutralized to clean the plant bottom of the plant industry. Its bottom is contaminated with animal and vegetable fats. The bottom was thoroughly cleaned, the washed water was recovered and found to be toxic to the flora or fauna and Emilon was completely stable.

Example 4

After mixing 7 parts of isofurophylamine with 35 parts of oleic acid and completely neutralizing the whole with ammonia, it is a mixture of oleine isofurophylamide and ammonium oleate, again mixed with lecithin and white srifit 29 A composition containing wt% amide and ammonium salt mixture, 3.3 wt% lecithin and 7.7% white spirit is formed. The composition is diluted to six times the weight with water and then used to clean various brews and cisterns, which contain hydrocarbons and fats.

Example 5

13 parts of diethanolamine, 18 parts of capric acid and 35 parts of oleic acid were mixed together to form a mixture of an oleate of caprylic diethanol amide and an ammonium oleate.

35 parts of this mixture was added in 3.5 parts of lecithin and 60.5 parts of petroleum solvents, and used in the same manner as described for the composition of Example 1-4.

Example 6

Lactic acid and 9 parts of 2-ethyl-hexanoic acid were added to 10 parts of dodecylamine, and the whole mixture was neutralized with ammonia to mix 2-ethyl-hexanoate of dodecylamide with ammonium 2-ethyl-hexanoate. Formed.

35 parts of this mixture was mixed with 5 parts of lecithin and 60 parts of n-hexane. The same result was obtained using the obtained composition in the same manner as described for the composition obtained in the above examples.
