Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an organic matter recovery composition for pulling and recovering various liquid organic matter, including spilled oil, at room temperature.

With the increase in the transportation of oil by oil tankers and other vehicles, accidents are occurring frequently, and oil is often spilled onto the sea, rivers, etc., causing serious social problems. It is expected that a technology for recovering various liquid organic substances, such as edible oil, etc., will be established.In the past, various studies have been conducted on methods for collecting and collecting the spilled oil and the pulling agent used therein. Dibenzylipensolditol and its nuclear substituted products, M-acyl P trinoic acid tridots, w-acylamino acid amine salts, ■-acylamino acid esters, etc., as well as dibenzylidenesolditol, its nuclear substituted products. , M-acylamino acid amides, N-p-acyl P amino acid amine salts and IV-
The present invention relates to a composition for recovering organic matter, characterized in that it contains at least one member selected from the group consisting of 7 amino acid esters.

The composition of the present invention, which contains the above hydrogenated castor oil and other specific compounds alone as a gelling agent component, contains dibenzylidansorpitol, etc., which are known to have the best organic matter recovery effect as a gelling agent component. It exhibits an organic matter recovery effect comparable to that of this type of composition used as a solvent. That is, it exhibits the effect of selectively and easily pulling organic substances by normal current operation. In addition, the composition of the present invention in which the above-mentioned specific compound is used in combination with certain compounds known as gelling agent components such as dibenzylidansolditol, has a synergistic effect. It is possible to achieve extremely excellent pull recovery rate, pull speed, pull hardness, etc. that are impossible to achieve.

In the present invention, as described above, hydrogenated castor oil, 12-hydro'+cystearic acid, 9,10
It is essential to use at least one of -dihydro-distearic acid and these amides. The above amide includes an amide obtained by reacting each of the above compounds with a monovalent or divalent amine. Examples of monovalent or divalent amines that are advantageous for producing the amide include ammonia, polymine, al↑-0-alamine, ethylenediamine, polydilenediamine, and the like.

Sarae: The above amide also includes methylene disamide and the like. The compound used as the gelling agent component of the invention by Jokiki has of course never been used in a composition for recovering organic matter of this type, and the inventors independently discovered that this compound is effective as a gelling agent component. This is a new fact.The above compounds are conventionally known as thickeners, but other compounds known as similar thickeners, such as stearin soap, 12-hydro+distearic acid soap, stearin Acid salts and the like cannot substantially function as a gelling agent component. Further, high melting point solid substances similar in properties to the above compounds, such as paraffin wax, stearic acid, tristicinic acid, and behenic acid, do not act as gelling agents.

The composition for recovering organic substances of the present invention is prepared by dissolving at least ltl of the specific gelling agent component compound in an organic solvent. The organic solvent used here is not particularly limited, provided that it can uniformly dissolve or disperse the gelling agent component compound in the resulting composition and that the composition is in a liquid state. Any of the usual ones used in the preparation of compositions can be used. Preferred solvents include, for example, M9M-dimethylformamide, W
, N-dime-1 acetamide, dimethyl-1-acetamide,
Ethylene carbonate, Surbonran, Methyl SeD Solp, Ethyl/SeD Sorp, ■-Methyl DiD Ridone, N-
zuOpyr-2-pyrrolidone, 〃-ethyl-2-pyrolidone, /l/, #-dimethylacrylic Pmido, N-dinyldiolidone, IV, W-dimethylcols, hydrocarbons, higher fatty acids Esters or ethers, higher unsaturated carboxylates such as oleic acid, vegetable oils, etc., hydrophobic solvents such as Epo + silicides, etc.
1 m of 2-diOridone and the like can be used alone or in combination of two or more. The concentration of the gelling agent component in the composition of the present invention prepared in the form of the above-mentioned solvent solution is usually 2-40
Weight t%, preferably about 5-33 weight t%, is preferable, but of course this concentration depends on the type of gelling agent component and solvent used, as well as the amount of the resulting composition and how it is utilized. It can be increased or decreased as appropriate depending on I[J[, etc., of the organic matter to be recovered. The amount of the thus obtained composition of the present invention to be used is not particularly limited, but the amount of organic matter to be recovered is usually
Parts by volume: about 5-100 parts by volume, preferably about 10-60 parts by volume
It may be a volumetric part, and thereby the organic matter can be almost completely recovered as a pull.

The present invention also provides a specific compound characterized by the above-mentioned hydrogenated castor oil as a gelling agent component, and a certain type of known pulling agent.
The present invention also provides compositions in which the component compounds are used in combination. The gelling agent component compounds used in combination in the above are dibenzylidenesol ditol and its nuclear substituted product, N-! Selected from sylamino acid P-tridos, Ny sylamino acid amine salts and Np sylamino acid esters. Here, the nuclear substituents of dibenzylidansolditol include lower alkyl groups, halogen atoms, and lower alkyl groups as substituents on the aromatic nucleus. Includes those having Ru + Cy groups, etc. Also W-7
Y-syl amino acid! The acyl group in the amide or N-dosyl triphosphate amine salts has 2 to 18 carbon atoms, and the amine component constituting the amide or P triphosphate is ann-7-ion or carbon number 1-is. Preferably, it has an alkyl group of

Further, the acyl group of the N-acyl P trinoic acid ester is the same as above, and the alcohol component constituting the ester preferably has an alkyl group having 8 to 18 carbon atoms. The second gelling agent component compound used in combination is used in a concentration range of about 2-301% by weight, preferably about 3-25% by weight in the resulting composition, and in this case, the above-mentioned hydrogenated castor oil is The particular gelling agent component compound featured may be used in the composition at a concentration of about 2-25% by weight, preferably about 3-20%, bringing the total pulling agent concentration to about 4-25% by weight. 3
The optimum range is 0% by weight.

According to the above-mentioned combined use, both of the pulling agent component compounds act mutually and a composition exhibiting particularly excellent effects can be obtained. That is, the resulting composition not only has a significantly shortened pulling speed and improved pull recovery rate, but also can impart remarkable hardness to the recovered gelled material. These effects can be obtained not only when each gelling agent component compound is used alone, but also when each gelling agent component compound is used alone.
This cannot be achieved no matter how many known gelling agent component compounds are used in combination.

The preparation of the composition of the present invention using two or more gelling agent component compounds belonging to the above-mentioned different groups can be carried out by dissolving or dispersing the same pulling agent component compounds in the same organic solvent in the same manner as described above. The composition for recovering organic matter of the present invention can also contain K, various additives, etc., as well as the known acid compounds. Examples of such additives include nonionic, oxidative, or amphoteric surfactants for dissolving or dispersing the gelling agent component more uniformly in the resulting composition, as well as potassium, sodium, lithium, Examples include salts of metals such as calcium, magnesium, and aluminum, polyolefins, and oligomers such as timer bags. The above-mentioned surfactant can generally be present in the composition in an amount of about 1% by weight or more. The metal salt can improve the storage stability of the resulting composition when added at about 2% by weight or more, and the metal salt can be recovered using the composition when added at about 1% by weight or more. The upper limit of the amount of the secondary additive that may be useful for the stability of the pull is within the range that allows the resulting composition to remain liquid at room temperature. Like the recovery composition, it can be widely used for collecting and recovering organic matter such as oil spilled on water, as well as for pulling and recovering edible oil and the like. Examples of organic substances pulled and recovered by the composition of the present invention include crude oil, heavy oil, naphtha, kerosene,
Various phthalates such as DOP and DHP, lubricating oils, higher alcohols, gasoline, ethyl acetate, bempine, toluene, Shishin, Plu↑Luhenzen, aniline, paraffin, α-olefin, various Epo+Cyto, and phenols. ,
Examples include organic heponic compounds, nido compounds, animal and vegetable oils, amines, nitriles, ketones, and animal and vegetable oil methyl esters. Gelation and recovery of secondary organic substances using the composition of the present invention can be carried out by simply injecting or spraying the composition of the present invention onto the secondary organic substances in accordance with a conventional method. The composition of the present invention can also be colored by injecting it together with water into the organic substance, if necessary. According to the application of the composition of the present invention, organic matter quickly and almost completely gels (assimilates) at room temperature, and in the case of oil spilled on water, only the oil layer or oil film is selectively collected and pulled. The pulled product obtained in this way is strong and has high hardness, and can be collected and recovered very easily using a net, for example, and the oil content can be regenerated from the collected pulled oil by dilution, distillation, etc. can.

As described above, the present invention provides an effective and economical composition and method that can selectively recover only the oil by pulling an organic oil film formed on water, such as oil spilled on water. This is extremely effective as a new technology for dealing with oil spills, which is a problem today.
