Description
본 발명은 칼슘을 함유하지 않은 신규한 보르도액 및 그 제조방법에 관한 것이다. 더욱 상세하게는, 본 발명은 PH12.0 수준의 강알칼리성 수산화 칼륨용액을 제조한 다음 여기에 황산구리와 분산제를 혼합하여 커드상 물질을 제조한 후 PH14.0 수준의 8 노르말농도의 별도로 제조한 수산화칼륨용액에 첨가하여 용해하므로써 맑은 청색(light blue)을 보유하는 신규한 타입의 무칼슘 보르도액을 제조하는 방법에 관한 것이다.The present invention relates to a novel Bordeaux liquid containing no calcium and a method for producing the same. More specifically, the present invention is prepared by preparing a strong alkaline potassium hydroxide solution of PH12.0 level and then mixing copper sulfate and a dispersant therein to prepare a curd material, and prepared separately prepared at pH 8 normal concentration of 8 normal concentration The present invention relates to a process for producing a novel type of calcium-free Bordeaux solution that retains light blue by addition to a potassium solution.
종래 석회가 함유된 보르도액(Bordeaux mixture)의 제조방법은 생석회(CaO)를 물에 첨가하여 24시간 이상 방치해두면 수화반응에 의하여 수산화칼슘[Ca(OH)2]이 되어 PH12.2수준의 강알칼리성 상등수를 얻게되고 상기 상등수에 황산구리(CuSo4)를 첨가하여 반응시키면 일차적으로 황산(H2SO4)이 생성됨과 동시에 살균력이 있는 구리이온(Cu+2)이 유리되며, 점차 반응이 진행되면서 침전되어 있던 상기 수산화칼슘이 다시 상기 황산과 반응하여 수불용성의 황산칼슘(CaSO4)과 물을 생성하며 반응하지 못한 유리된 구리 2가이온은 물중에 존재하게 되고 이것이 음성대전 (Negative charge)하는 미생물세포에 작용하므로서 세포생리를 중단시켜 유전정보 (DNA)의 활성을 교란하므로서 병원미생물이 살균되고 화학적 식물방제 역할을 다하게 된다.In the conventional method of preparing Bordeaux mixture containing lime, quick alkali (CaO) is added to water and left for more than 24 hours to produce calcium hydroxide [Ca (OH) 2 ] by hydration reaction. When the supernatant is obtained and reacted by adding copper sulfate (CuSo 4 ) to the supernatant, sulfuric acid (H 2 SO 4 ) is first generated and copper ions (Cu +2 ) having a bactericidal power are liberated, and the reaction proceeds gradually. The calcium hydroxide reacts with the sulfuric acid again to produce water-insoluble calcium sulfate (CaSO 4 ) and water, and the free copper divalent ions that do not react are present in the water, which is negatively charged. By disrupting cell physiology and disrupting the activity of genetic information (DNA) by acting on the pathogenic microorganisms are sterilized and plays a role in chemical plant control.
종래 보르도액의 제조방법을 반응공정에 따라 도식화하면 하기 반응식과 같이 표현할 수 있다.If the conventional method for preparing Bordeaux liquid is schematized according to the reaction process, it can be expressed as the following reaction formula.
CaO+H2O→Ca(OH)2…①CaO + H 2 O → Ca (OH) 2 ... ①
CuSO4+2H2O→H2SO4+Cu2++2(OH-)…②CuSO 4 + 2H 2 O → H 2 SO 4 + Cu 2+ +2 (OH − )... ②
Ca(OH)2+H2SO4+Cu2+→CaSO4↓+2H2O+Cu 2+…③Ca (OH) 2 + H 2 SO 4 + Cu 2+ → CaSO 4 ↓ + 2H 2 O + Cu 2+ ... ③
상기 반응식에서 보는 바와 같이하여 제조되는 종래 칼슘을 함유한 보르도액은 첫째, 제조과정 중 제1공정에서 냉각시간이 경우에 따라서는 1시간이상 소요된다는 단점이 있고 둘째, 고품질의 수산화칼슘을 사용하지 않으면 양질의 보르도액을 제조할 수 없다는 결점이 있으며 마지막으로 이와 같이 하여 제조된 종래의 보르도액은 포도, 복숭아, 밀감 등의 식물에 살포하였을 경우 미반응된 수산화칼슘이나 불용성의 황산칼슘이 상기 과수식물의 잎에 부착되어 왕성한 호흡작용을 저해하고 그 결과 식물의 광합성율을 저하시켜 과실의 숙성이 다소 불리할 경우가 있고 또 황백색의 상기 수용성 칼슘화합물이나 불용성 칼슘화합물이 과실에 점착되는 경우 상품의 품위에 손실을 입히게 된다.Bordeaux liquid containing a conventional calcium prepared as shown in the reaction scheme has the disadvantage that first, the cooling time in the first step of the manufacturing process in some cases takes more than 1 hour, and secondly, if you do not use high quality calcium hydroxide Finally, the conventional Bordeaux solution prepared in this way has unreacted calcium hydroxide or insoluble calcium sulfate attached to the leaves of the fruit trees when sprayed on plants such as grapes, peaches, and citrus. As a result, vigorous respiratory action is inhibited, and as a result, the photosynthesis rate of the plant is lowered, and the ripening of the fruit may be somewhat disadvantageous, and if the yellow-white water-soluble calcium compound or insoluble calcium compound adheres to the fruit, the product quality is lost. .
본 발명은 상기와 같은 종래 보르도액의 제 단점이나 결점을 해소하여 용이하게 고품질의 신규한 보르도액을 제공하는데 그 목적이 있다.The present invention aims to solve the above-mentioned disadvantages and drawbacks of the conventional Bordeaux liquid and to provide a novel high quality Bordeaux liquid.
본 발명의 다른 목적은 효과적이고 우수한 품질의 신규한 타입의 보르도액 제조방법을 제공함에 있다.Another object of the present invention is to provide a novel type of Bordeaux liquid production method of effective and excellent quality.
이하, 본 발명의 구체적인 구성 및 작용을 설명하지만 본 발명의 공정순서의 변경 및 원료와 수치의 간단한 변경에 의해 본 발명의 상기 목적이 달성될 수 있으므로 본 발명의 권리범위는 이와같은 공정의 변경수치와 원료의 단순한 변경의 모든것에 미치는 것은 물론이다.Hereinafter, the specific constitution and operation of the present invention will be described, but the above object of the present invention can be achieved by a simple change of the process order of the present invention and a raw material and a numerical value, so that the scope of the right of the present invention changes the numerical value of such process. Of course, it affects everything from simple changes of raw materials.
본 발명의 상기 목적은 강알칼리성의 수산화칼륨용액을 제조한 다음 CuSO4와 분산제 ZnSO4를 혼합하여 강산성의 Curd상 물질을 생성시키고 PH14.0수준의 8N의 별도로 제조한 수산화칼륨용액에 투입하여 상기 Curd상 물질을 용해시키고(PH13.8) 이를 평가함으로써 달성하였다.The object of the present invention is to prepare a strongly alkaline potassium hydroxide solution, and then mixed with CuSO 4 and dispersant ZnSO 4 to produce a strongly acidic Curd phase material, and added to 8N prepared separately prepared potassium hydroxide solution of PH14.0 level. This was achieved by dissolving the Curd phase material (PH13.8) and evaluating it.
도 1은 본 발명의 바람직한 공정을 설명한 개략적인 흐름도로서 본 발명의 구성은 KOH를 순수에 용해시켜 강알칼리성의 수산화칼륨용액을 제조하는 단계와; CuSO4와 분산제 ZnSO4를 혼합하여 상기 KOH수용액에 용해하여 Curd상 물질을 제조하는 단계와; 상기 Curd상 물질을 8N의 별도로 준비한 KOH 수용액에 용해하여 등청색(light Blue), 무칼슘의 보르도액을 제조하는 단계로 구성된다1 is a schematic flowchart illustrating a preferred process of the present invention, the composition of the present invention comprises the steps of dissolving KOH in pure water to prepare a strongly alkaline potassium hydroxide solution; Mixing CuSO 4 and a dispersant ZnSO 4 to dissolve in the KOH aqueous solution to prepare a Curd phase material; The Curd phase material is dissolved in 8N separately prepared KOH aqueous solution to prepare a light blue, calcium-free Bordeaux solution.
이하, 본 발명의 구체적인 구성을 실시예를 들어 설명한다.Hereinafter, the specific structure of this invention is given and mentioned an Example.
실시예 1Example 1
본 발명 칼슘을 함유하지 않은 신규한 등청색 보르도액을 제조하기 위하여 제1단계로 KOH 0.4g을 1리터의 H2O에 용해시켜 PH12.0의 수산화칼륨용액을 제조하였다.In order to prepare a novel blue-blue Bordeaux solution containing no calcium of the present invention, 0.4 g of KOH was dissolved in 1 liter of H 2 O in the first step to prepare a potassium hydroxide solution of PH12.0.
이와 별도의 용기에 KOH 450g을 1리터의 H2O에 용해시켜 PH14.0이상이 되도록 8N의 KOH수용액을 제2단계로 제조하였다.The KOH aqueous solution of 8N was prepared in a second step so that 450 g of KOH was dissolved in 1 liter of H 2 O in a separate container so as to have a pH of 14.0 or more.
다음 제3단계로 황산구리(CuSO4) 65g과 분산제로서 황산아연(ZnSO4) 15g을 칭량하여 혼합한 후 상온에서 상기 제1단계에서 제조된 KOH수용액 약 650㎖에 용해하여 PH4.0으로 조정하였다. 이때 이들 화학물질들은 반응하여 Curd상태로 존재하였다.In the third step, 65 g of copper sulfate (CuSO 4 ) and 15 g of zinc sulfate (ZnSO 4 ) as a dispersant were weighed and mixed, and then dissolved in about 650 ml of an aqueous KOH solution prepared in the first step at room temperature, and adjusted to PH 4.0. . At this time, these chemicals reacted and exist in Curd state.
상기 제3단계에서 생성된 Curd상의 물질 150㎖를 취하여 제2단계에서 별도로 제조된 8N 수산화칼륨수용액에 용해하였더니 제4단계 반응결과 등청색(light blue) 무칼슘 보르도액이 되었으며 이때 PH는 13.8로 조정되었다.150 ml of the Curd phase material produced in the third step was taken and dissolved in 8N potassium hydroxide solution prepared separately in the second step. As a result of the fourth step, the result was a light blue calcium-free Bordeaux solution with a pH of 13.8. Adjusted.
상기 제4단계 반응결과 생성된 물질은 물에 2가 구리이온이 완전히 해리된 상태의 칼슘이 없는 신규한 형태의 보르도액이 되는 것이다.The material produced as a result of the fourth step reaction is a novel form of Bordeaux liquid without calcium in a state where divalent copper ions are completely dissociated in water.
만일, 제4단계 반응시 본 발명 공정의 제3단계에서 생성된 Curd상태의 물질을 180㎖이상 가하게 되면 수소이온농도가 PH13.8이상이 되어 검은 수용액이 되어 사용할 수 없는 것이 되고 150㎖이하를 첨가하여 용해하게 되면 PH가 낮아져서 Curd상태의 물질이 용해되지 않아 사용할 수 없으며 제품수율도 현저히 떨어져서 상품가치가 없게 된다.If the Curd material generated in the third step of the process of the present invention is added to 180ml or more, the hydrogen ion concentration becomes PH13.8 or more, so that it cannot be used as a black aqueous solution. When added and dissolved, the pH is lowered, so the Curd substance is not dissolved and cannot be used. Product yield is also significantly reduced, resulting in no product value.
본 발명은 이상 실시예를 통하여 설명한 바와 같이 Ca수용액이나 침전물이 존재하지 않으므로 종래의 보르도액과 같이 불용성의 Ca침전물이 살포되는 식물의 잎에 침적하지 않는 새로운 형태의 보르도액을 제공하는 효과가 있으며 지금까지 존재하지 않던 새로운 타입의 보르도액 제조방법을 제공하는 뛰어난 효과가 있으므로 농약 산업상 매우 유용한 발명인 것이다.The present invention has the effect of providing a new type of Bordeaux solution, which does not deposit on the leaves of plants to which insoluble Ca precipitates are sprayed as in the conventional Bordeaux solution, since there is no Ca aqueous solution or precipitate as described above. It is a very useful invention for the pesticide industry because it has an excellent effect of providing a new type of Bordeaux liquid manufacturing method that did not exist.
