ていた。[Conventional technology] Waste animal and vegetable oils such as tempura oil that remain after making fried foods such as tempura can cause contamination of rivers and seawater downstream if they are poured into sewers. When incinerated, a lot of smoke and bad odor were generated, which could cause pollution, and it was difficult to dispose of it. Conventionally, treatment methods to eliminate these harmful effects include adding chemical agents to the waste oil to solidify it, or absorbing it into pulp and disposing of it in the soil, or turning it into soap. .

状等も悪く品質的に問題が有った。[Problems with the Prior Art] However, when the solidified material is absorbed into pulp and disposed of, it is bulky and difficult to handle, and furthermore, if it is incinerated, it causes pollution as described above. In addition, when making soap, heat treatment is usually performed during the treatment process.
Especially when using a gas stove at home, there is a risk of oil spilling and causing a fire, which poses a safety problem.In addition, the soap produced by this method has a strong oily odor that will stick to washed items. It was uncomfortable to use, and the color and appearance were poor, leading to quality issues.

The purpose of the present invention is to provide a waste oil treatment agent and a treatment method thereof that improve the quality of the soap, such as not giving off a bad odor.To achieve this purpose, the general formula Sin, ・nM2O (where n
= 1 to 3, M = Na or K) A waste oil treatment agent prepared by adding a surfactant to an aqueous solution of a silicate, or an aqueous solution of a silicate to which the surfactant is added, and a peroxide salt or the following. A waste oil treatment agent consisting of chlorite and a chelating agent is used, and in the case of the latter, a predetermined amount of waste oil is mixed with
Mix an appropriate amount of a 40% aqueous solution with a surfactant, add several percent of peroxide salt or hypochlorite, and a chelating agent, and perform soaping by stirring at high speed at room temperature with a high-speed stirrer.

After mixing an appropriate amount of a waste oil treatment agent prepared by adding a surfactant to an aqueous solution of the silicate represented by a or K) into the waste oil and stirring, the waste oil is almost completely removed by simply leaving it at room temperature for several days (5 to 7 days). It is turned into soap.

Thus, the oil odor of the soap produced by adding peroxide or hypochlorite almost disappears, and the color of the oil changes from yellowish brown to light yellow, and the chelating agent eliminates the turbidity of the soap. Furthermore, soap can be produced in a very short time by stirring at high speed with a high speed stirrer.

0 g, 90 g of the 40% aqueous solution of potassium orthosilicate and 40 g of polyoxyethylene alkyl ether were mixed, and at the same time, 3 g of sodium percarbonate and 2 g of EDTA (sodium ethylenediaminetetraacetate) as a chelating agent were added.

し透明度を増す。Moreover, the soap had almost no bad odor resulting from the waste oil, and the color changed from yellowish brown to light yellow and also disappeared. In general, waste oil is darkly colored and has a strong odor, so the soap produced from it is yellowish-brown and has a strong odor. Adding it changes the color of the soap to pale yellow and eliminates the odor. Furthermore, by adding ED'TA as a chelating agent, the turbidity of the soap is eliminated and the transparency is increased.

い。Orthosilicate is preferably used as an aqueous solution with a concentration of 30 to 40% in an amount such that the amount of free alkali is 5 to 10% higher than the saponification value of waste oil than the amount of alkali required for soapification. If the amount of water is small, the soap produced will solidify and be difficult to stir, and if the amount of water is large, it will be difficult to soap. Furthermore, if an excessive aqueous solution of orthosilicate is used, the residual alkali in the soap after saponification will become excessively large, which is undesirable.

In addition to ether, polyoxyethylene alkylphenol ethers or fatty acid alkylolamides are preferred, and these are nonionic activators, but anionic activators can also be used, although the quality of the soap produced in this case is slightly inferior. It is possible.

ていた。[Conventional technology] Waste animal and vegetable oils such as tempura oil that remain after making fried foods such as tempura can cause contamination of rivers and seawater downstream if they are poured into sewers. When incinerated, a lot of smoke and bad odor were generated, which could cause pollution, and it was difficult to dispose of it. Conventionally, treatment methods to eliminate these harmful effects include adding chemical agents to the waste oil to solidify it, or absorbing it into pulp and disposing of it in the soil, or turning it into soap. .

うもので色・性状等も悪く品質的に問題が有った。In addition, when making soap, heat treatment is usually performed during the processing process, and especially when it is done at home using a gas stove, there is a risk of oil spilling and a fire, which poses a safety problem. The soap produced by this method had a strong oily odor, and the odor lingered on washed items, giving an unpleasant sensation, and the color and properties were poor, resulting in quality problems.

Using a 30% soap solution, mix 150 g of animal/vegetable tempura waste oil (saponification value 197) with 100 g of the silicic acid aqueous solution and 5 g of the soap solution, stir the whole well, and then store at room temperature (25°C). Leave it for about 7 days. Then, during this time, the soap liquid as the surfactant acts as a catalyst, promoting emulsification of the tempura waste oil and potassium silicate, and uniformly promoting the soapification of the tempura waste oil. After 7 days, a paste-like soap is produced, with a pure soap content of 58% and a petroleum ether soluble content (neutral fat + unsaponifiable content) of 1.1%.

透明度を増す。Furthermore, the soap had almost no bad odor caused by waste oil, and the color changed from yellowish brown to pale yellow, and it also lost its turbidity. In general, waste oil is darkly colored and has a strong odor, so the soap produced from it is yellowish-brown and has a strong odor. Adding it changes the color of the soap to pale yellow and eliminates the odor. Furthermore, by adding EDTA as a chelating agent, the soap becomes less cloudy and more transparent.

If the amount of water is small, the soap produced will harden and become difficult to stir, and if the amount of water is large, it will be difficult to soap. Moreover, if an excessive aqueous solution of silicate is used, the residual alkali in the soap after saponification will become excessively large, which is not preferable.
