Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to water-readily dispersible industrial disinfectant compositions. More specifically, the present invention relates to a powdery, easily dispersible industrial sterilizing composition which is useful for slime gonds in industrial cooling water systems during the papermaking process, and which contains acetic acid ester as an active ingredient.

It is known that haloacetic acid ester μ is effective for slime contamination (0-IK) in industrial cooling water systems during the paper process.

Usually, these haloacetic acid esters are added directly to an aqueous system or diluted with an organic solvent such as acetone, xylene, dimethylformamide, etc., and added in the form of a diuretic preparation. However, in the former case, the haloacetic acid ester has a specific gravity of 1 or more, which is unfavorable in terms of rounding dispersibility, as will be described later, while in the latter liquid preparation, the organic solvent used is generally expensive and the stability of the preparation is poor. There are problems in terms of storage, transportation, and handling, such as insufficiency (particularly in aqueous preparations and in hydrophilic organic solvents, bar acetate easily decomposes).

On the other hand, as a method to efficiently release corrugated materials that have conventionally been misplaced into p-water, the corrugated materials are held in a water-releasable or insoluble carrier such as calcium carbonate, silica sand, burrite, bentonite, etc., and powdered. A method is known in which the formulation is added to water (Japanese Patent Publication No. 5211061 and Japanese Patent Application Laid-open No. 5211061).
(See Publication No. 2-7438). Also, JP-A-58-536
Publication No. 0ji discloses a powder preparation in which a slime agent is adsorbed onto petal-like silica that is insoluble in mineral water, and a dispersion aid such as a surfactant is not used.

However, Kayo 5 & water-soluble or not #1+! When using a carrier of 100%, it is added to the target water system and becomes cloudy due to large dust, and the carrier itself has a hot point that causes scale. In addition, in the case of KMI in the papermaking process, the above-mentioned carrier retains the active ingredients and is incorporated into the paper, which has a negative effect on the paper quality. Atsuku.

Therefore, there is a need for an industrial straw killer that can disperse haloacetic esters with excellent efficiency* without creating scale in the target water system, does not affect the papermaking process, and has good 111I4 stability. This invention has been made in view of these various points. Thus, this departure from WA

Provided is a powdery, water-readily dispersible industrial disinfectant composition comprising eight or more of calcium chloride, iIl lucicum acetate, magnesium sulfate, or these inorganic salts. Point K: The component haloacetic acid ester is rapidly dispersed in water in the form of a finely divided powder preparation without causing cloudiness in the scale due to the carrier.

Next, the boiling point, specific gravity and refractive index of typical haleacetic acid ester μ used in this invention are shown in Table 1. Bromoacetate is preferred. Such haloacetic acid ester is contained in 6 to 40 parts by weight in 100 parts by weight of the preparation.
Although it is possible to formulate a formulation with less than 1 part by weight, it is not suitable due to the economical KsP. Moreover, if it exceeds 40 parts by weight, it is not possible to form a powdered formulation.

It is believed that the sodium bicarbonate and/or potassium bicarbonate used in this invention function to disperse the haloacetic ester into IK particles when added to water. Such bicarbonate contains 5 to #SO in 100 parts by weight of the formulation.
Contains parts by weight. If the amount is less than 60 parts by weight, the dispersibility of the hetetraacetic ester is insufficient; if it is more than 60 parts by weight, the amount of the inorganic salt shown below decreases, making it impossible to obtain a fluid powder.

In this invention, the two components am include sodium carbonate, sodium sulfate, calcium chloride, acetic acid-jI
~Sium, sulfuric acid! Two or more of these inorganic salts are blended. These are made by mixing the above two components to eliminate the base plating, and by using similar fluid inorganic salts such as sodium chloride, sodium nitrate, potassium chloride, ammonium nitrate, etc. Unable to obtain formulation.

It is preferable to use an anhydrous salt as the inorganic salt used in the above invention from the viewpoint of formulation stability. Furthermore, among the inorganic salts, it is most preferable to use anhydrous salts of sodium sulfate and/or magnesium sulfate.

The blending amount of these inorganic salts can vary between 10 and 90 parts by weight depending on the total amount of the two components, but (a) if it is too small, a fluid powder 41 cannot be obtained. It is preferable to add the same amount or more to sodium and/or potassium bicarbonate.

The industrial sterilizing composition of the present invention can be easily obtained by appropriately blending the respective components.

Specifically, for example, a mixing container K equipped with a stirrer is prepared by mixing a predetermined amount of the above-mentioned bicarbonate and a predetermined amount of an inorganic salt (both in powder form), and after death, a predetermined amount of liquid haloacetic acid ester P is mixed. It can be obtained by adding a fixed amount and stirring and mixing.

However, the method for producing the composition of the present invention is not affected by the mixing order of the three components as long as they are mixed in a predetermined ratio. In Maruda Industrial production, it is preferable to add the haloacetic ester last in order to prevent the haloacetic ester from adhering to the mixing container.
o The composition of the present invention obtained in this manner is particularly effective against slime generated in the process water system of the paper manufacturing process, circulation cooling type heat exchangers used in various factories, drainage ditches, etc.
It is useful as a control agent for spheroids that occur in cooling towers, etc. In addition to this, it can be used for various target systems as long as it is bactericidal or bacteriostatic.Although such a composition is in powder form, it can also be used for scale I by itself. Therefore, the antibacterial activity of the haloacetic acid ester is efficiently exhibited. Also, it does not have any effect on paper quality during the paper manufacturing process. Furthermore, it is more economical than conventional liquid formulations, and has far superior formulation stability, which is advantageous in terms of storage, transportation, and handling. In addition, the manufacturing method is simple and industrially useful.The amount of the composition of this invention to be added varies depending on the object to be treated.
JI, but usually, haloacetic acid ester is applied to the water to be treated.
is added in an amount of about 6 to 100 pp.Next, Jin's invention will be explained in more detail with reference to examples, but the invention is not limited thereby.

Example 1 Using 1,4-bromoacetoxybutene-2 as the haloacetic acid ester, and using bicarbonate and various inorganic salts in various ratios, compound preparations were prepared. 9 cases in which a powdered preparation with sexual properties is obtained.

The results are shown in Table 3.

In this way, the formulation Ryu 38 containing 115 1,4-bromoacetoxybutene-2 has an antibacterial activity of 1.
．． When using 4-bromoacetoxybutene-2 alone (100
It can be seen that the antibacterial activity is 1/6 of that of φ), and the antibacterial activity is not reduced in any way even when used as a cram school or powder preparation. Therefore, it can be seen that it has excellent dispersibility.
