Description
본 발명은 연료전지와 수소 연소 장치 등의 수소를 이용하는 장치에 수소를 공급하기 위한 수소 저장(Hydrogen Storage) 물질로 사용 가능한, 피리딘 그룹을 포함하는 방향족 화합물의 신규한 제조방법에 관한 것이다.The present invention relates to a novel manufacturing method of an aromatic compound containing a pyridine group that can be used as a hydrogen storage material to supply hydrogen to devices that use hydrogen, such as fuel cells and hydrogen combustion devices.
화석 에너지의 고갈 및 환경 오염 문제로 인하여 신재생 대체 에너지에 대한 요구가 크며, 이에 대한 대체 에너지의 하나로서 수소가 주목받고 있다. 특히 연료전지와 수소 연소 장치의 경우 수소를 반응 가스로 사용하고 있는데, 연료전지와 수소 연소 장치를 예컨대 자동차나 각종 전자 제품 등에 응용하기 위해서는 수소의 안정적이고 지속적인 공급 기술이 요구된다.Due to the depletion of fossil energy and environmental pollution problems, there is a great demand for new and renewable alternative energy, and hydrogen is attracting attention as one of the alternative energies. In particular, fuel cells and hydrogen combustion devices use hydrogen as a reaction gas, and in order to apply fuel cells and hydrogen combustion devices to automobiles and various electronic products, for example, a stable and continuous supply technology for hydrogen is required.
수소를 이용하는 장치에 있어서 수소를 공급하기 위해서는 별도로 설치된 수소 저장 장치 (수소 공급 장치)로부터 수소가 필요할 때마다 수소를 공급받는 방식을 사용할 수 있다. 대표적인 예로는 압축수소저장 및 액화수소저장 방법이 있는데, 이들 기술은 수소 생산처로부터 수소 수요처까지 수소를 이송하는데 가격 및 안전에 대한 이슈가 있을 수 있다.To supply hydrogen in a device using hydrogen, a method can be used in which hydrogen is supplied from a separately installed hydrogen storage device (hydrogen supply device) whenever hydrogen is needed. Representative examples include compressed hydrogen storage and liquefied hydrogen storage. These technologies transport hydrogen from hydrogen producers to hydrogen consumers, but there may be issues regarding price and safety.
예를 들어, 수소는 최대 875 bar의 압력에서 저장하기에 적합한 고압 탱크에 압축된 형태로 저장될 수 있다. 또한 적합한 극저온 용기, 바람직하게는 초절연(superinsulated)된 극저온 용기에 저온 액화 수소의 저장이 공지되어 있다. For example, hydrogen can be stored in compressed form in high-pressure tanks suitable for storage at pressures of up to 875 bar. It is also known to store cold liquefied hydrogen in suitable cryogenic vessels, preferably superinsulated cryogenic vessels.
이외에, 수소를 저장하고 발생시키는 물질을 수소 이용 장치에 탑재하여, 해당 물질을 반응 시켜 수소를 발생시키고, 이를 공급하는 방식을 사용할 수 있다. 이 방식에는 예컨대, 금속수소화물(metal hydride) 이용 방법, 흡착, 탈착/탄소 (absorbents/carbon) 이용 방법, 화학적 수소저장 방법(chemical hydrogen storage) 등이 제안되고 있으며, 암모니아 보레인, 실란 화합물, 개미산 등과 같은 다양한 화학수소화물을 이용한 수소저장 기술이 연구되고 있다.In addition, a method of loading a material that stores and generates hydrogen into a hydrogen utilization device, reacting the material to generate hydrogen, and supplying the hydrogen can be used. For this method, for example, methods using metal hydride, adsorption, desorption/carbon (absorbents/carbon) methods, and chemical hydrogen storage methods are proposed, and ammonia borane, silane compounds, Hydrogen storage technology using various chemical hydrides such as formic acid is being studied.
이와 더불어, 최근에는 가역성이 용이한 유기화합물을 이용한 수소저장기술이 활발하게 이루어지고 있는데, 예로, 일본에서는 경제적 수소 이송을 고려하여 톨루엔 기반의 수소저장기술이 연계된 수소 발전소를 구축하고 있으며, 독일에서는 디벤질 톨루엔 계열의 화합물을 기반으로 하여 가역적 수소저장 특성을 규명하고자 하고 있다. In addition, hydrogen storage technology using easily reversible organic compounds has been actively developed in recent years. For example, Japan is building a hydrogen power plant with toluene-based hydrogen storage technology in consideration of economical hydrogen transport, and Germany is building a hydrogen storage technology using toluene-based hydrogen storage technology. is attempting to identify reversible hydrogen storage characteristics based on dibenzyl toluene series compounds.
상기에서 언급한 화합물을 기반으로 하는 가역적 수소저장기술은 실험적 단계에 있는 것으로, 수소와 화학적으로 결합할 수 있는 수소화(hydrogenation)가 가능한 유기 화합물에서 수소의 저장이 이루어진다. Reversible hydrogen storage technology based on the compounds mentioned above is in the experimental stage, and hydrogen is stored in hydrogenated organic compounds that can chemically combine with hydrogen.
구체적으로 에너지가 부족한 물질(A)에 수소를 로딩하여 에너지가 풍부한 물질(B)을 형성하며, 에너지 로딩 작업은 전형적으로 초대기압 압력(superatmospheric pressure) 하에 촉매 수소화 반응의 종래 기술의 형태를 취한다. 물질(B)은 저압과 고온에서 촉매 수소화에 의해 에너지가 언로딩된다. 공정에서 다시 방출된 수소는, 예를 들어, 연료 전지 또는 연소 엔진에서 에너지 공급원으로 유용하다. 에너지가 부족한 형태(A)는 이 경우 에너지가 풍부한 시간에 에너지가 풍부한 장소에서 수소로 재로딩될 수 있도록 액체로 저장되고 운송될 수 있다. 이러한 유형의 시스템은 액체 유기 수소 운반체(liquid organic hydrogen carriers, LOHCs)로 알려져 있다. Specifically, hydrogen is loaded into an energy-poor material (A) to form an energy-rich material (B), and the energy loading operation typically takes the form of a prior art catalytic hydrogenation reaction under superatmospheric pressure. . Material (B) is unloaded with energy by catalytic hydrogenation at low pressure and high temperature. The hydrogen released again in the process is useful as an energy source, for example in fuel cells or combustion engines. The energy-poor form (A), in this case, can be stored and transported as a liquid so that it can be reloaded with hydrogen at an energy-rich location at an energy-rich time. These types of systems are known as liquid organic hydrogen carriers (LOHCs).
종래 기술 LOHC 시스템은 물질 쌍(substance pairs)인 것이 바람직하고, 여기서, 에너지가 부족한 물질(A)은 에너지 로딩 단계에서 수소화된 끓는 점이 높은 작용기화 방향족 화합물이다. 개시되어 있는 한 가지 특히 바람직한 예는 물질 쌍 N-에틸카바졸/퍼히드로-N-에틸카바졸을 사용하는 것에 관한 것으로, 이는 전형적으로 약 140℃ 및 높은 압력에서 에너지 로딩을 허용하고 230℃ 내지 250℃의 온도에서 에너지 언로딩(energy unloading)을 허용한다. 에너지가 풍부한 물질인 퍼히드로-N-에틸카바졸은 언급된 시스템에서 수소의 질량 기준으로 약 5.8%의 수소 용량(hydrogen capacity)을 갖는다.Prior art LOHC systems are preferably substance pairs, where the energy-deficient substance (A) is a high boiling functionalized aromatic compound that is hydrogenated in the energy loading step. One particularly preferred example disclosed relates to the use of the material pair N-ethylcarbazole/perhydro-N-ethylcarbazole, which typically allows energy loading at about 140° C. and high pressures and has a temperature range of 230° C. to 230° C. Energy unloading is allowed at a temperature of 250°C. Perhydro-N-ethylcarbazole, an energy-rich material, has a hydrogen capacity of about 5.8% by mass of hydrogen in the mentioned system.
이와 관련된 종래기술로서, 한국등록특허 제10-1845515호(공고일: 2018.04.04)에서는 액상 수소저장물질로서, 1,1'-바이페닐과 1,1'-메틸렌다이벤젠을 1:1.8 내지 1:2.5의 중량비율로 포함하는 액상 수소저장물질을 제시하였으며, 또한 한국등록특허 제10-1862012호(공개일: 2018.03.19)에서는 피리딘계 수소저장물질을 활용한 수소 저장 및 방출 시스템에서 피리딘계 수소저장물질을 합성함에 있어서 2-피리딘메탄올을 출발물질로 사용하여 합성한 제조예가 개재되어 있다.As a related prior art, Korea Patent No. 10-1845515 (announcement date: 2018.04.04) uses 1,1'-biphenyl and 1,1'-methylenedibenzene at a ratio of 1:1.8 to 1 as a liquid hydrogen storage material. A liquid hydrogen storage material containing a weight ratio of :2.5 was presented, and in Korea Patent No. 10-1862012 (publication date: 2018.03.19), a pyridine-based hydrogen storage and release system using a pyridine-based hydrogen storage material was proposed. In synthesizing a hydrogen storage material, a production example using 2-pyridinemethanol as a starting material is provided.
그러나 상기 제조예에서 출발물질로 사용된 2-피리딘메탄올보다 낮은 단가를 가지는 피리딘계 유도체를 출발물질로 사용하여 수소저장물질을 합성하는 방법의 개발을 통해서 수소저장물질의 생산단가를 낮출 수 있을 것으로 기대된다.However, it is expected that the production cost of the hydrogen storage material can be lowered through the development of a method of synthesizing the hydrogen storage material using a pyridine-based derivative with a lower cost than 2-pyridine methanol used as the starting material in the above production example. It is expected.
따라서 현재까지는 이러한 불포화고리를 포함하는 수소저장물질을 합성하기 위한 기술개발이 개선의 여지가 있으며, 이에 본 발명자는 피리딘 그룹을 포함하는 방향족 화합물이 상기 연료전지와 수소 연소 장치 등의 수소를 이용하는 장치에 수소를 공급하기 위한 수소 저장(Hydrogen Storage) 물질로서 사용할 수 있음을 알았으며, 또한 상기 피리딘 그룹을 포함하는 방향족 화합물의 신규한 제조방법을 확인하고 본 발명을 완성하였다.

본 발명의 첫 번째 단계인 a) 단계는, [반응식 1]내, 화합물 a로 표시되는 피리딘 유도체의 산화 반응으로부터 화합물 b로 표시되는 화합물을 제조하는 단계이며, 이에 관해 하기에서 설명하도록 한다.Step a), the first step of the present invention, is a step of preparing a compound represented by compound b from the oxidation reaction of a pyridine derivative represented by compound a in [Scheme 1], which will be described below.
<피리딘 유도체의 산화 반응><Oxidation reaction of pyridine derivative>
상기 단계 a)는 하기 [반응식 1]내, 화합물 a로 표시되는 피리딘 유도체의 산화 반응으로부터 화합물 b로 표시되는 피리딘-N-옥사이드 유도체를 합성하는 단계이다.Step a) is a step of synthesizing a pyridine-N-oxide derivative represented by compound b from the oxidation reaction of a pyridine derivative represented by compound a in the following [Scheme 1].
[반응식 1][Scheme 1]
상기 a)단계에서의 화합물 a로 표시되는 피리딘 유도체의 산화 반응은 산화제로 피리딘 또는 피리딘 유도체를 산화시킬 수 있는 산화제는 어떠한 것도 사용할 수 있으며, 산소, 과산화수소(H2O2), 산소, 과산화수소(H2O2), 메타클로로퍼벤조익에시드(m-chloro perbenzoic acid,mCPBA), 디메틸디옥시렌(Dimethyldioxirane) 중에서 선택되는 어느 하나 또는 이들의 혼합물을 이용할 수 있다.In the oxidation reaction of the pyridine derivative represented by compound a in step a), any oxidizing agent capable of oxidizing pyridine or a pyridine derivative can be used, including oxygen, hydrogen peroxide (H 2 O 2 ), oxygen, hydrogen peroxide ( H 2 O 2 ), m -chloro perbenzoic acid (mCPBA), dimethyldioxirane, or a mixture thereof may be used.
이때, 산화제의 사용량은 상기 피리딘 또는 피리딘 유도체 1 몰 당량에 대하여 1 내지 5몰 당량으로 사용하는 것이 바람직하다. 산화제의 사용량이 1몰 당량보다 작을 경우에는 원하는 전환율을 얻을 수 없으며, 5몰 당량을 초과하여 사용하여도 더 이상 전환율이 증가하지 않으므로 더 이상 사용할 필요는 없다.At this time, the oxidizing agent is preferably used in an amount of 1 to 5 mole equivalents per 1 mole equivalent of the pyridine or pyridine derivative. If the amount of oxidizing agent used is less than 1 molar equivalent, the desired conversion rate cannot be obtained, and even if it is used in excess of 5 molar equivalents, the conversion rate does not increase any further, so there is no need to use it any more.
상기 피리딘 유도체의 산화 반응에서 과산화수소를 산화제로 사용할 경우 유기 촉매를 사용할 수 있으며, 아세트산(acetic acid)을 단독으로 촉매로 사용하거나 아세트산과 황산을 함께 촉매로 사용하는 방법이 있다. 다른 방법으로는 말레인산(maleic acid) 또는 무수말레인산(maleic acid anhydride), 프탈산(phthalic acid) 또는 무수프탈산(phthalic acid anhydride)과 같은 카르복실산 유도체를 촉매로 사용하는 방법이 있으나, 이에 제한되는 것은 아니다.When hydrogen peroxide is used as an oxidizing agent in the oxidation reaction of the pyridine derivative, an organic catalyst can be used. There is a method of using acetic acid alone as a catalyst or acetic acid and sulfuric acid together as catalysts. Other methods include, but are limited to, using maleic acid or carboxylic acid derivatives such as maleic acid anhydride, phthalic acid, or phthalic acid anhydride as catalysts. no.
a) 단계에서의 산화 반응의 반응조건은 30~150 ℃ 온도 범위인 것이 바람직하며, 산화 반응을 30℃ 미만의 온도에서 실시하는 경우에는 반응 진행이 매우 느리며, 150℃를 초과하는 온도에서 실시할 경우에는 산화제, 예를 들면 과산화수소의 증발과 분해를 촉진시켜 산화제, 예를 들면 과산화수소의 반응의 참여가 거의 이루어지지 않는다.The reaction conditions for the oxidation reaction in step a) are preferably in the temperature range of 30 to 150 ℃.

Pt 및 Pd 지지 촉매는 탈수소화 반응은 회분식 유리 반응기 (90 cm3)를 사용하였으며. 탄소 혹은 알루미나에 지지된 Pt 혹은 Pd 촉매를 반응 전에 반응 용기의 바닥에 미리 장입한 후, 반응물(7.732 mmol)을 반응기 내에 주입하였다. 여기서 금속 촉매(M)와 반응물(R)의 비율(M/R)은 0.1 내지 0.6 몰% 범위이다. 내부의 수분 및 산소를 제거하기 위해 10분 동안 질소(N2) 가스를 퍼징 한 후, 반응기를 230 ℃에서 19 분간, 250 ℃에서 22 분간 또는 270 ℃에서 25 분간 열전 사식 순환 재킷을 사용하여 가열하였다. 탈수소화 반응이 4 시간 동안 수행되는 동안, 방출된 수소(H2) 가스의 부피는 유리 뷰렛에서 옮겨진 물의 양으로 측정되었다. 교반은 수소 생성 속도에 영향을 미치지 않았으며, 반응이 완료되면 반응기를 실온으로 냉각시켰다. GC 결과로부터 산출된 수소(H2) 가스의 몰수는 뷰렛에 의해 측정된 수소(H2) 가스의 몰과 유사하였다. 탈수소화 생성물에 대한 선택성 및 수소 생성 수율은 하기 표 2 및 도 2에 기재하였다.A batch glass reactor (90 cm 3 ) was used for the dehydrogenation reaction of the Pt and Pd supported catalysts. A Pt or Pd catalyst supported on carbon or alumina was previously charged to the bottom of the reaction vessel before reaction, and then the reactant (7.732 mmol) was injected into the reactor. Here, the ratio (M/R) of the metal catalyst (M) and the reactant (R) is in the range of 0.1 to 0.6 mol%. After purging with nitrogen (N 2 ) gas for 10 min to remove moisture and oxygen inside, the reactor was heated using a thermal circulation jacket at 230 °C for 19 min, 250 °C for 22 min, or 270 °C for 25 min. did. While the dehydrogenation reaction was carried out for 4 hours, the volume of hydrogen (H 2 ) gas released was measured as the amount of water transferred in a glass burette. Agitation did not affect the rate of hydrogen production, and the reactor was cooled to room temperature once the reaction was complete. The number of moles of hydrogen (H 2 ) gas calculated from the GC results was similar to the moles of hydrogen (H 2 ) gas measured by a burette. Selectivity for dehydrogenation products and hydrogen production yields are shown in Table 2 and Figure 2 below.
