Abstract
Description
본 발명은 수성 클로로옥사이드-용액의 제조방법에 관한 것이다. 미합중국 특허 제 3,585,147호에는 동시에 알카리금속 아연소산염과 알카리-또는 알카리토-염화물을 물에 용해하고 pH의 값을 7 내지 13으로 조정하여 인정한, 수성 클로로옥사이드-용액을 제조하는 방법이 기술되어 있다.The present invention relates to a process for the preparation of an aqueous chlorooxide-solution. U.S. Patent No. 3,585,147 describes a method for preparing an aqueous chlorooxide solution, which is simultaneously recognized by dissolving an alkali metal zinc sulphate and an alkali or alkaline-chloride in water and adjusting the pH value to 7 to 13. .
pH 값을 6 이하로 조절하는 경우, 클로로 디옥사이드가 유리되는데, 클로라이드가 존재하면 다량의 클로로 디옥사이드가 유리될 수 있다. 공지된 방법에서는 클로라이드 부재하에 단지 소량의 클로로디옥사이드만이 유리된다. 그러나 여기에서의 단점은, 상기한 공지된 방법에 의하여 얻어진 알카리성 아염소산나트륨-용액은 비교적 빨리 아염소산나트륨으로 역반응이 진행되어서, 예를 들어서 여러달 동안의 장기간 저장은 불가능하다는 것이다.When the pH value is adjusted to 6 or less, chloro dioxide is liberated, where a large amount of chloro dioxide can be liberated if chloride is present. In known processes only a small amount of chlorodioxide is liberated in the absence of chloride. A disadvantage here, however, is that the alkaline sodium chlorite-solutions obtained by the above known methods undergo a reverse reaction with sodium chlorite relatively quickly, for example, long term storage is impossible for several months.
본 발명의 목적은, 안정하고도 장기간의 저장이 가능하며, 클로로옥사이드가 다량으로 용해된 수성 클로로옥사이드-용액을 제공하는데 있다. 이 목적은 아래의 방법에 의해서 달성되었다. 즉 15 내지 45중량-부의 물에 35 내지 105중량-부의 아염소산염과 10 내지 30중량부의 차아염소산염을 첨가하여, 여기에서 얻어진 수성 용액에 3 내지 9중량-부의 무기산을 서서히 첨가하여서 pH의 값을 3 내지 4로 산성화한 후, 계속해서 1 내지 2중량-부의 탄산나트륨을 첨가하여 pH의 값을 6.5 내지 7.5로 조정한다.It is an object of the present invention to provide an aqueous chlorooxide-solution in which stable and long term storage is possible and in which a large amount of chlorooxide is dissolved. This object was achieved by the following method. That is, 35 to 105 parts by weight of chlorite and 10 to 30 parts by weight of hypochlorite are added to 15 to 45 parts by weight of water, and 3 to 9 parts by weight of inorganic acid is gradually added to the aqueous solution obtained to obtain a pH value. After acidification to 3-4, the pH value is then adjusted to 6.5-7.5 by addition of 1-2 parts by weight sodium carbonate.
본 발명에 따른 방법에서는 클로라이드 부재하에 수행하는데, 미합중국 특허 제3,585,147호에서와 같이 다량의 클로로옥사이드가 생성되어 용액내에 함유된다. 클로로옥사이드-용액을 함유하는 물은 냄새-및 맛에 영향을 끼치지 않으며, 더욱이 클로로아민의 생성도 역시 억제된다. 따라서, 특히 본 발명에 따른 방법에 의해서 제조된 클로로옥사이드-용액을 음료수와 목욕물에 사용할 때에 유리하다. 음료수의 자연적인 냄새와 맛에 전혀 영향을 끼치지 않으며, 또한 목욕물의 경우에는 클로로아민의 생성에 따르는 피부의 가려움증이나 안질환 등에 대한 위험도 없게된다. 무엇보다도 유리한 점은 수성 클로로옥사이드-용액이 단지 탄산나트륨 만으로도 안정화되기 때문에, 부수적으로 과산화물과 같은 안정제의 필요성이 전혀 없다는 것이다. 본 발명에 따라 제조된 클로로옥사이드-용액은 몇달 이상을 두어도 인정하기 때문에, 이 물질의 사용범위를 광범위하게 넓힐 수 있으며, 또 사용시의 인정성도 매우 우수하다. 마지막으로 특히, 음료수 정제에 사용할 수 있다는 점이 중요하다. 본 발명에 따라 제조된 수성 클로로옥사이드-용액은 또한 산화제-및 소독제로서 일반적으로 사용되는 물, 냉각수 및 폐수에 유익하게 사용할 수가 있다.The process according to the invention is carried out in the absence of chloride, in which a large amount of chlorooxide is produced and contained in solution, as in US Pat. No. 3,585,147. Water containing chlorooxide-solutions does not affect odor and taste, and furthermore the production of chloroamine is also inhibited. It is therefore particularly advantageous when the chlorooxide-solutions prepared by the process according to the invention are used in drinking water and bath water. It does not affect the natural smell and taste of the drink at all, and in the case of bathing water, there is no risk of itching or eye disease caused by the production of chloroamine. An advantage above all is that there is no need for stabilizers such as peroxides, since the aqueous chlorooxide-solution is stabilized only with sodium carbonate. Since the chlorooxide-solution prepared according to the present invention can be recognized even after several months, the range of use of this material can be broadly widened, and the recognition at the time of use is also excellent. Last but not least, it can be used for beverage tablets. The aqueous chlorooxide-solutions prepared according to the invention can also be advantageously used in water, cooling water and waste water which are commonly used as oxidant- and disinfectants.
본 발명에 따른 방법의 목적에 따라서 더욱 유리한 변형 방법등은 청구범위에 설명되어 있다. 다음 실시예는 본 발명의 방법을 설명하기 위해 제시한 것이다.Further advantageous modification methods and the like according to the object of the method according to the invention are described in the claims. The following examples are presented to illustrate the method of the present invention.
[실시예]EXAMPLE
30중량-부의 물에 70중량-부의 30%의 아염소산나트륨-용액과 20중량-부의 16%의 차아염소산 나트륨-용액을 첨가하고, 여기에서 얻어진 수성용액에 6중량-부의 10%의 황산용액을 첨가하여 pH의 값을 약4로 조정한다. 이 산성 수성용액은 일정한 반응시간이 경과하면 클로로옥사이드가 형성되는데, 여기에 안정제로서 1.5중량-부의 98% 내지 100%의 탄산나트륨을 첨가하여, pH의 값을 약 7.0으로 조정한다.To 30 parts by weight of water, 70 parts by weight of 30% of sodium chlorite-solution and 20 parts by weight of 16% of sodium hypochlorite-solution are added, and 6 parts by weight of 10% of sulfuric acid solution to the aqueous solution obtained The pH value is adjusted to about 4 by addition. This acidic aqueous solution forms chloro oxide when a certain reaction time has elapsed. The pH value is adjusted to about 7.0 by adding 1.5 parts by weight of 98% to 100% sodium carbonate as a stabilizer.
이러한 방법에 의해서 얻어진 수성용액은 20 내지 25%의 클로로옥사이드를 함유하며, pH의 값은 약 7.0이다.The aqueous solution obtained by this method contains 20 to 25% chlorooxide and the pH value is about 7.0.
