Description

Gelling agent composition, organic solvent and/or oil-based gelation method, organic solvent and/or oil-based absorber, and organic solvent and/or grease treatment method

The present invention relates to a gelling agent composition, an organic solvent and/or a grease-based gelation method, an organic solvent and/or an oil-based absorber, and an organic solvent and/or a grease. More specifically, it relates to a gelation method of an organic solvent, animal and vegetable oil, mineral oil, or the like.

Gelling agents are widely used in various applications, namely, oil recovery agents, cosmetics, pharmaceutical products, inks and other viscosity modifiers, pesticides, spices and other Xu agent, plastics, rubber processing aids. In recent years, low-molecular organic gelling agents have attracted attention and various studies have been conducted on this function. For example, sorbitol diformaldehyde, 12-hydroxystearic acid, a cholesteryl decylamine compound, a sugar derivative, etc. are mentioned as a low molecular-organic organic gelatinization agent (for example, refer to Non-patent document 1).

However, the known low molecular organic gelling agent does not function adequately. For example, generally, for a gelled object, a high addition amount is not used, and the desired gel strength cannot be produced. In addition, since almost all of the gelling agent is added to the gelled object, it must be heated and dissolved, then cooled and gelatinized. The operation is cumbersome, and the applicable use is very limited. Therefore, there is a strong demand for the development of novel low molecular organic gelling agents or gelling processes which have low added amounts and which do not require heating or cooling operations to form gels of high gel strength.

The present inventors have proposed an organic solvent or a gelatinizing agent which can be gelatinized by adding a resin acid, an alkaline earth metal compound, or an alkaline earth metal salt of a resin acid to a gelled object, or a method of using the same (refer to the patent document) 1. Patent Document 2). Although this method has the advantage of gelatinizing the gelled object at room temperature, when the gelation is carried out, the resin acid dissolved in the gelled object must react with the solid alkaline earth metal compound to form an alkaline earth metal of a resin acid. salt. However, this reaction is a reaction between a resin acid solution dissolved in a gelled object and a solid, and the gel formation time is indefinite depending on the viscosity of the gelled object or the stirring state at the time of gelation, and sometimes it takes a very long time. time.

The best form for implementing the invention

As the resin acids used in the present invention, known materials can be used, but dehydroabietic acid and dihydroabietic acid are preferred from the viewpoint of gelation ability. Dehydroabietic acid is a method described in Journal of Organic Chemistry, 1966, vol. 31, p. 4246 to 4247, and dihydroabietic acid is 138-Δ8-dihydroabietic acid, which is disclosed in JP-A-51-149256. The method described.

The rosin to be used in the present invention is not particularly limited, and known ones can be used. Specifically, rosin which is a raw material of wood rosin, tall oil rosin, gum rosin, etc., and hydrogenated using the raw material rosin can be used. Rosin, disproportionated rosin, polymerized rosin, dehydrogenated rosin, and the like. Among these, it is preferable to use a rosin which is rich in dehydroabietic acid and dihydroabietic acid from the viewpoint of gelation ability. For example, disproportionated rosin or dehydrogenated rosin having dehydroabietic acid as a main component and hydrogenated rosin as a main component of dihydroabietic acid can be mentioned.

The alkaline earth metal salt of the rosin to be used in the present invention is not particularly limited, and known ones can be used. Specifically, for example, the above-mentioned rosin is neutralized with an alkaline earth metal. Among these, as the alkaline earth metal salt, for example, a magnesium salt, a calcium salt, a phosphonium salt, a phosphonium salt or the like can be used. In particular, disproportionated rosin or dehydrogenated rosin or hydrogenated rosin magnesium or calcium salt can be effectively used industrially. These rosin alkaline earth metal salts may be used singly or in combination of two or more kinds as appropriate.

The mixture of the alkaline earth metal salts of rosin and rosin may be prepared by mixing the components, but may also control the neutralization rate when the rosin forms an alkaline earth metal salt. The neutralization ratio in the formation of the alkaline earth metal salt of the rosin is not particularly limited, but is preferably from 5 to 60% with respect to the rosin acid value, and particularly preferably from 15 to 50%. When the neutralization rate is less than 5%, the softening point of the metal salt becomes low, and when mixed with the alkaline earth metal compound or during the storage after the mixing, the metal salt reacts with the alkaline earth metal compound to change the composition, and gelatinizes. The trend of reduced ability. When the neutralization rate exceeds 60%, the gelation ability is lowered, and the dissolution rate of the gelled object tends to be slow.

In addition, the alkaline earth metal compound to be used in the present invention is not particularly limited as long as it reacts with the above-mentioned resin acid or rosin to form an alkaline earth metal compound of a salt, and is oxidized by an alkaline earth metal in consideration of reactivity. Preferably, the earth or alkali metal hydroxide is used. Specific examples of the metal compound include magnesium hydroxide, magnesium oxide, calcium hydroxide, calcium oxide, barium hydroxide, cerium oxide, cerium hydroxide, cerium oxide, and the like. Any of these alkaline earth metal compounds may be used singly or in combination of two or more kinds as appropriate. Among these, from the viewpoint of gelation ability, calcium hydroxide, barium hydroxide, barium hydroxide, calcium oxide, barium oxide and barium oxide are preferred.

Water is indispensable in the gelling process of the present invention. It is considered that the presence of water dissolves an alkaline earth metal oxide or an alkaline earth metal hydroxide in water to accelerate the reaction with the resin acid. The amount of water used is 0.05% by weight or more based on the weight of the gelled object. When it is less than 0.05% by weight, the gelation time becomes long and the practicality is lowered.

The composition of at least one selected from the group consisting of such resin acids, rosins, and alkaline earth metal salts, and the composition of the alkaline earth metal compound is not particularly limited, and the type of gelatinized object or the amount of water used is considered. Etc., the decision can be chosen appropriately. For example, a non-polar to medium-polar organic solvent such as hexane, heptane, cyclohexane, benzene, toluene or xylene (specifically, a solvent having a dielectric constant of 3.0 or less); gasoline, kerosene, light oil, heavy oil, Mineral oils such as crude oil, flowing paraffins, mechanical oils, cutting oils, and engine oils; general animal and vegetable oils such as soybean oil, rapeseed oil, and salad oil, which have excellent gelling ability, and the gelation time is very short and effective. The gelation method of the present invention will be described in detail below.

After the first system is added with water to the gelled object, at least one selected from the group consisting of resin acids, rosins, and alkaline earth metal salts thereof, and a mixture of alkaline earth metal compounds are added. At this time, the alkaline earth metal compound may be dispersed by stirring to form an object to be gelled as a whole, or may be left to stand still after stirring to achieve desired gelation.

The second system is a method in which at least one selected from the group consisting of a resin acid, a rosin, and an alkaline earth metal salt thereof, and a mixture of an alkaline earth metal compound in a gelled object, followed by the addition of water. Stir at this time, and then stir or stand still.

As described above, at least one selected from the group consisting of a resin acid, a rosin, and an alkaline earth metal salt, and a mixture of an alkaline earth metal compound (hereinafter, referred to as a gelling agent, if necessary) ), and the order in which the water is added is arbitrary, and depending on the workability or use, a suitable method can be employed.

Further, as a method of adding at least one selected from the group consisting of a resin acid, a rosin, and an alkaline earth metal salt thereof, an alkaline earth metal compound and water, as described above, a rosin and/or a rosin type is used in advance. A mixture of an alkaline earth metal salt and an alkaline earth metal compound is suitable from the viewpoint of gelation operation, but may not be premixed with an alkali earth metal salt or an alkaline earth metal compound of a resin acid, a rosin, and/or a rosin or a resin acid. And water can be separately added to the gelled object.

According to any of the above methods, the amount of the gelling agent to be added to the gelled object can be appropriately determined depending on the type of the gelatinized object. It is usually from 1 to 30% by weight, preferably from 2 to 10% by weight, and less than 1%, and is not likely to cause gelation, even if it exceeds 30%.

In each of the above methods, at least one selected from the group consisting of resin acids, rosins, and alkaline earth metal salts, and the shape or size of the alkaline earth metal compound are not particularly limited, but are improved to resin acids. The viewpoint of the dissolution rate or dispersibility of the gelled object is preferably selected from the group consisting of resin acids, rosins, and alkaline earth metal salts, and any of the alkaline earth metal compounds is a powder having a relatively uniform shape. The gelling agent is at least one selected from the group consisting of resin acids, rosins, and alkaline earth metal salts thereof, and the mixture ratio with the alkaline earth metal compound is resin acid and/or rosin and/or rosin alkaline earth. The molar ratio of free resin acid (including rosin-based resin acid) to alkaline earth metal compound (free resin acid (mole number) / alkaline earth metal compound (mole number)) remaining in the metal salt is 1/0.5 It is suitable to 1/10. When the molar ratio is less than 1/0.5, sufficient gelation cannot occur. Further, when the molar ratio exceeds 1/10, the desired gelation can be achieved, but the unreacted alkaline earth metal remains in a large amount, resulting in high cost and no particular advantage. Further, depending on the type of the alkaline earth metal salt, no free resin acid is required. For example, in the case of a magnesium salt, a free resin acid is not particularly required. However, in the case of the magnesium salt, as described above, it is preferred to have a free resin acid. On the other hand, in the case of a calcium salt, as described above, it is preferred to have a free resin acid.

In the present invention, the temperature at which the gelation target is gelled is not particularly limited, and usually it can be appropriately set in the range from room temperature to the boiling point of the gelled object, but the gelatinization system can be rapidly formed at room temperature. Features of the invention. In addition, in order to increase the dissolution rate of the resin acid when the gelatinization viscosity of the animal or vegetable oil or mineral oil is increased, the heating can be shortened to the end of the gelation.

According to any of the above methods, at least one selected from the group consisting of resin acids, rosins, and alkaline earth metal salts in the presence of a gelled object, reacts with an alkaline earth metal compound to form an alkaline earth of a resin acid. The metal salt is presumed to function as a gelling agent for the gelled object.

The gelation method of the present invention is applicable to the treatment of a solvent or a grease when it coexists with water. Specifically, the solvent or fat floating on the water is gelatinized, and it can be easily recovered and treated. At this time, the solvent or the mixture of the oil and the water is stirred, and the above gelation method can be employed.

Further, at the time of the gelation, a gelling agent containing at least one selected from the group consisting of a resin acid, a rosin, and an alkaline earth metal salt, and a mixture of an alkaline earth metal compound, and water and an oil absorbing material are coexistent. Since the diffusion of the gelled object such as a solvent or a grease can be increased, the gelled object can be gelled without stirring. The oil absorbing material is not particularly limited as long as it can absorb the oil or fat, and known materials can be used. Specifically, for example, a powder having porosity, a powder having a multilayer structure, and the like can be given.

Examples of the powder having a multilayer structure include vermiculite, mica, and the like. The amount of the oil-absorbing material to be used is not particularly limited, but is usually from 10 to 5,000 parts by weight with respect to 100 parts by weight of the gelled object, and from 50 to 2,000 with respect to 100 parts by weight of the gelled object. The degree of weight is suitable. It is preferable to use 50 parts by weight or more of the oil-absorbing material by using 50 parts by weight or more of the oil-absorbing material, and it is preferable to use 2000 parts by weight or less with respect to 100 parts by weight of the gelled object. Oil-absorbing material, gelled oil-absorbing oil, is suitable because it can increase the strength of the gel.

At least one selected from the group consisting of a resin acid, a rosin, and an alkaline earth metal salt thereof, and an alkaline earth metal compound, and a gelling agent composition of the oil absorbing material, because in the presence of water The gelling ability is high, so that the gelling agent composition can be used as a medium. For example, blending and compounding are equivalent to various fibers or non-woven fabrics, and can be used as an organic solvent and/or an oil-based absorber. Specific examples of the fiber or the nonwoven fabric include natural fibers such as cellulose fibers and kapok fibers, synthetic fibers such as polyethylene, polypropylene, polyester, and polyamide, and non-woven fabrics and the like. In addition, at least one selected from the group consisting of a resin acid, a rosin, and an alkaline earth metal salt thereof, and an alkaline earth metal compound and a water composition are merely mixed and composited in the above-described oil absorbing material. A fiber (for example, a cellulose fiber) can be an absorber of an organic solvent and/or a fat or oil. The absorption system may change the content of the above gelling agent composition for the purpose of use, and may generally contain an oil absorbing material of an amount of from 10 to 5,000 parts by weight based on 100 parts by weight of the gelling agent.
