Description

유독가스 중화제 조성물Toxic Gas Neutralizer Composition

본 발명은 유독가스의 악취성분을 흡수제거하거나 일산화탄소(Co 가스) 중독을 방지하는 유독가스 중화제 조성물에 관한 것이다.The present invention relates to a toxic gas neutralizer composition for absorbing and removing odor components of toxic gases or preventing carbon monoxide (Co gas) poisoning.

좀더 상세히 설명하면 현재 일반가정 및 요식업의 연료로서 주로 프로판가스, 석유 및 연탄등을 사용함으로서 연소중에 필연적으로 발생되는 일산화탄소, 아황산가스등의 유독가스 및 그의 악취성분을 중화제거함으로서 실내 공기정화는 물론 Co가스중독을 예방하는 유용한 약제를 제공하는 것이다.In more detail, it is currently used as propane gas, petroleum and briquettes as fuel for general home and catering industry, and neutralizes toxic gases such as carbon monoxide and sulfurous acid gas and its odorous components generated during combustion. It is to provide a useful drug to prevent gas poisoning.

종래에도 6% 암모니아수와 8% 식초산수용액은 5 : 5(용량비)의 비율로 호합하거나 10% 암모니아수와 5% 식초산수용액을 7 : 1(용량비)의 비율로 혼합한 혼합액을증발 또는 발산공이 뚫려 있는 용기에 주입하고 사용시는 뚜껑을 열어 실내에서 자연발산하거나 흡수력이 우수한 흡수지에 흡수 방산하도록 되어 있는 일산화탄소 중독 방지제가 공지되어 있다(특허공고 번호 79-409호) 그리고 이의 실험결과에 의하면 농도 0.3% 일산화탄소 가스 중독에 대한 동물의 식초산과 암모니아의 영향은 6% 암모니아수와 8% 식초산수용액(용량비 5:5)에서 사망율이 가장 낮아서 전무한 것으로 되어 있으며, 또 인체에 대한 시험에 있어서는 연탄가스 1600-2000PPM에서 밀실의 크기 4방 7자에서 10% 암모니아와 5% 초산수용액(용량비 7:1)을 혼합한 약제의 증발에서 7시간 경과에도 하등 인체에 이상이 없는 것으로 시험 결과 밝혀졌다.Conventionally, 6% ammonia water and 8% vinegar aqueous solution are mixed at a ratio of 5: 5 (volume ratio) or a mixture of 10% ammonia water and 5% vinegar acetic acid at a ratio of 7: 1 (volume ratio) is evaporated or diverted. Carbon monoxide poisoning inhibitors are known that are injected into a perforated container and used to dissipate naturally in the room by opening a lid or absorbing into an absorbent paper having excellent absorbing power (Patent No. 79-409). The effect of animal vinegar and ammonia on% carbon monoxide gas poisoning was the lowest in mortality in 6% aqueous ammonia and 8% aqueous vinegar solution (5: 5), and briquette gas 1600- At 2000PPM, the size of the chamber is 4-7%, and even after 7 hours of evaporation of the drug mixed with 10% ammonia and 5% acetic acid solution (volume ratio 7: 1) The test results revealed that there is no longer a member.

상기의 결과에 의하면 식초산이 연탄가스 중독환자 및 실험동물의 적혈구의 수를 증가시키고 호흡을 향진시키며 뇌에 가는 혈류량을 증가시키고, COHb의 해리를 신속히 진행지키는 것으로 추리될 수 있다.According to the above results, it can be inferred that vinegar acid increases the number of erythrocytes of briquette gas poisoning patients and experimental animals, promotes breathing, increases blood flow to the brain, and rapidly dissociates COHb.

암모니아 또는 연탄가스중독환자 및 실험동물의 뇌혈류량을 증가시키는 것으로 나타났다.It has been shown to increase cerebral blood flow in patients with ammonia or briquette gas poisoning and experimental animals.

그러나 이같은 선행의 일산화탄소 중독방지제는 환자의 적혈구수를 증가시키고 혈류량을 증가시키며 COHb의 해리를 신속하게 진행시킬 뿐으로 인체에 유해한 공기중의 일산화탄소의 총량을 근원적으로 감소시킬 수는 없었다.However, these advanced carbon monoxide inhibitors could not reduce the total amount of carbon monoxide in the air that was harmful to the human body by increasing the number of red blood cells, increasing blood flow, and rapidly dissociating COHb.

본 발명자는 연료연소중에 필연적으로 발생하는 일산화탄소와 아황산가스등의유독가스를 함유하고 있는 실내공기를 정화할 수 있는 유독가스 중화제조성물을 제조하기 위해 연구를 거듭 진행한 결과 본 발명을 환성하기에 이르렀다.The present inventors have made great efforts to produce a toxic gas neutralizer composition capable of purifying indoor air containing toxic gases such as carbon monoxide and sulfurous acid gas, which are inevitably generated during fuel combustion.

본 발명 유독가스 중화제조성물의 중화메카니즘을 구체적으로 설명하는데는 다소 어려움이 있고 또 반응기전 규명은 불명하나 일산화탄소는 그 성질이 산소와 혼합하기 쉬운 환원성이 강한 것으로 식초산을 분해시켜 산소와 환원하여 이산화탄소가 되는 것으로 추리되며 암모니아수는 식초산과 작용하여 초산암모늄으로 되고 이것이 공기중에서 암모니아가스로 휘산되어 일산화탄소의 농도를 희석화하는 것으로 풀이된다.The neutralization mechanism of the toxic gas neutralizer composition of the present invention is somewhat difficult to explain in detail, and the identification of the reactor is unknown, but carbon monoxide has a high reducibility property that is easy to mix with oxygen and decomposes vinegar acid to reduce oxygen with carbon dioxide. Ammonia water acts with vinegar to form ammonium acetate, which is then vaporized with ammonia gas in the air to dilute the concentration of carbon monoxide.

또한 염산이 암모니아수와 작용하여 염화암모늄으로 되고 이것이 상온에서 암모니아와 염화수소가스로 해리 되면서 염산의 일부가 물과 반응하여 염화수(HCIO)로 되고 이 염화수(차아염소산)을 분해하여 산소를 일부발생 [HCIO→HCI+(O)]하여 공기중에서 환원성이 강한 일산화탄소와 결합하여 이산화탄소로 전환되면서 안개와 같은 효소체를 띄우며 그 일부는 발생기의 산소로서 공기중의 유해성분을 산화파괴하여 공기중의 유해성분을 제거하게 됨을 규명하게 된 것이다.In addition, hydrochloric acid reacts with ammonia water to form ammonium chloride, which dissociates into ammonia and hydrogen chloride gas at room temperature, and part of the hydrochloric acid reacts with water to form hydrochloric acid (HCIO) and decomposes this chloride (hypochlorous acid) to generate some oxygen. [HCIO → HCI + (O)] combines with carbon monoxide, which is highly reducible in air, and converts it into carbon dioxide, which releases an enzyme like fog, some of which is oxygen of the generator, oxidizing and destroying harmful components in the air. It is clear that the removal of.

또한 소오다는 이들 Co가스 및 유독가스와의 민감한 중화반응으로 흡수를 강하게 하는 역활로 추리된다.Soda is also inferred from the role of strong absorption by sensitive neutralization with these Co and toxic gases.

본 발명에서 사용되는 염산은 공업적인 제법의 염산(농도 30%)이나 합성염산(농도 35-38%)어느것이라도 사용될 수 있으나, 사용할시 농염산의 농도를 낮게 5-10%정도로 하여 아연, 소오다 백반에 가하여 혼합하고 130℃로 약 60분간 가열하여 수용액으로 녹인 다음 식초산, 암모니아수와 물을 가하여 250℃로 약 10분간 가열하면 연푸른색을 띄우며 액체상태의 유독가스중화제 조성물을 제조한다.The hydrochloric acid used in the present invention may be any of industrial hydrochloric acid (concentration 30%) or synthetic hydrochloric acid (concentration 35-38%). The mixture is added to alum and mixed, heated at 130 ° C. for about 60 minutes, dissolved in an aqueous solution, and then heated to 250 ° C. for 10 minutes by adding vinegar acid, ammonia water and water to give a light blue color.

이와같이 제조되는 본 발명은 일정한 용기에 주입하거나 흡착지에 흡착시켜서 유독가스가 있는 장소에 비치하여 자연발산토록 뚜껑을 열어 휘산시키거나 분무기로 뿌려서 발산시켜 사용하는 것으로 본 발명에 있어 백반은 수용액으로 되는 조성물약제의 증발을 억제시켜 장기간 비치 사용케 하기 위해 사용되며, 염산, 아연, 소오다는 암모니아수, 식초산과 혼합으로 일산화탄소 및 아황산가스중에 민감한 중화반응으로 악취가스 흡수력이 강하고 우수한 그 흡수력과 혼농으로 실내공기 정화는 물론 유독가스중독을 예방할 수 있어 유용하게 이용될 수 있었다.The present invention prepared in this way is injected into a fixed container or adsorbed on a sorbent paper and stored in a place with toxic gas, open the lid to spontaneous divergence, or use it by sprinkling with a nebulizer. It is used to prevent evaporation of chemicals for long-term use, and hydrochloric acid, zinc and soda are neutralized in carbon monoxide and sulfurous acid by mixing with ammonia water and vinegar acid. Of course, it could be useful because it can prevent poisonous gas poisoning.
