Description
본 발명은, 규소이소시아네이트 화합물 함유 조성물의 제조 방법에 관한 것으로서, 보다 상세하게는, 공비 용제를 사용하여 탈수 공정을 실시하는 것을 특징으로 한 규소이소시아네이트 화합물 함유 조성물의 제조 방법에 관한 것이다.The present invention relates to a method for producing a composition containing a silicon isocyanate compound, and more particularly, to a method for producing a composition containing a silicon isocyanate compound characterized by performing a dehydration step using an azeotropic solvent.
규소이소시아네이트 화합물은, 예를 들어 알코올이나 제 1 아민, 제 2 아민, 카르복실산 등의 활성 수소를 분자 중에 포함하는 화합물과 용이하게 반응하기 때문에, 폴리머의 개질제로서 사용된다. 또한, 규소이소시아네이트 화합물은, 중합물의 성분으로서 용이하게 도입할 수 있어, 규소의 특성을 공업 재료에 부가할 수 있다. 또한, 규소이소시아네이트 화합물은, 물과 신속하게 반응하는 것으로부터, 공기 중의 수분, 또는, 유리, 세라믹스, 금속 등의 표면에 존재하는 흡착수 등과 반응하여, 밀착성이 높은 규소산화물 피막을 형성시킬 수 있다.A silicon isocyanate compound is used as a polymer modifier because it reacts easily with a compound containing active hydrogen in a molecule|numerator, such as alcohol, a primary amine, a secondary amine, and carboxylic acid, for example. Moreover, a silicon isocyanate compound can be easily introduce|transduced as a component of a polymer, and can add the characteristic of silicon to an industrial material. In addition, since the silicon isocyanate compound reacts rapidly with water, it reacts with moisture in the air, or adsorbed water present on the surface of glass, ceramics, metal, etc., to form a silicon oxide film with high adhesion.
규소이소시아네이트 화합물의 제조 방법으로는, 용제 존재하에서 Si-X (X 는 할로겐을 나타낸다) 결합을 갖는 할로겐화실란 화합물과 시안산염 또는 이소시안산염을, 알킬아민, 니트로알칸 또는 크라운 에테르의 존재하에서 반응시켜 제조하는 방법 (특허문헌 1) 이나, 할로겐화실란 화합물과 시안산염 또는 이소시안산염을, 알킬렌글리콜 화합물의 존재하에서 반응시켜 제조하는 방법 (특허문헌 2) 이 알려져 있다.As a method for producing a silicon isocyanate compound, a halogenated silane compound having a Si-X (X represents halogen) bond and a cyanate or isocyanate are reacted in the presence of an alkylamine, nitroalkane or crown ether in the presence of a solvent. A manufacturing method (patent document 1) and a manufacturing method (patent document 2) are known by making a halogenated silane compound and a cyanate or isocyanate react in presence of an alkylene glycol compound.
또한, 헥사오르가노디실라잔을, 염화철의 존재하에서, 탄산 가스와 반응시켜 제조하는 방법 (특허문헌 3), 트리클로로실란과 시안산알칼리를, 아세토니트릴을 소량 함유하는 유기 용매 중에서 반응시켜 제조하는 방법 (특허문헌 4), 유기 주석이소시아네이트류와, 활성 할로겐 원자를 갖는 유기 규소 화합물을 반응시켜 제조하는 방법 (특허문헌 5) 이 알려져 있다.In addition, a method for producing hexaorganodisilazane by reacting it with carbon dioxide gas in the presence of iron chloride (Patent Document 3), trichlorosilane and alkali cyanate in an organic solvent containing a small amount of acetonitrile. A method (patent document 4) and a method (patent document 5) in which organic tin isocyanates are reacted with an organosilicon compound having an active halogen atom are known.
한편, 규소이소시아네이트 화합물은, 물과의 반응에 의해, 다이머 화합물이나 올리고머 화합물을 형성하는 것이 알려져 있고 (예를 들어, 특허문헌 6), 반응계에 물이 혼입되었을 경우, 규소이소시아네이트 화합물 (의 모노머) 의 순도 저하로 연결된다.On the other hand, it is known that a silicon isocyanate compound forms a dimer compound or an oligomer compound by reaction with water (for example, Patent Document 6), and when water is mixed in the reaction system, the silicon isocyanate compound (monomer of) leads to a decrease in the purity of
이 때문에, 고순도의 규소이소시아네이트 화합물의 모노머를 얻기 위해서는, 원료가 되는 화합물로부터 물을 충분히 제거할 필요가 있다.For this reason, in order to obtain the monomer of a high-purity silicon isocyanate compound, it is necessary to fully remove water from the compound used as a raw material.
특허문헌 2 의 실시예에 있어서는, 탈수한 시안산염이나 이소시안산염을 사용하여 규소이소시아네이트 화합물을 제조하고 있지만, 사용하는 용제나 알킬렌글리콜과 같은 반응에 사용하는 다른 화합물의 탈수를 실시하지 않는 한, 할로겐화실란 화합물이 시안산염 또는 이소시안산염과 반응하기 전에, 함유하는 물과 반응하게 된다.In the Example of Patent Document 2, a silicon isocyanate compound is produced using dehydrated cyanate or isocyanate, but unless dehydration of another compound used in the reaction such as a solvent or alkylene glycol is performed. , before the halogenated silane compound reacts with the cyanate or isocyanate, it reacts with the water it contains.
시안산염 또는 이소시안산염의 탈수 방법으로서, 감압하에서 직화로 가열하여 탈수하는 방법이 알려져 있지만, 가열하여 탈수하는 공정과 반응 공정의 2 회의 공정을 거칠 필요가 있다. 또한, 산업 레벨에서의 실시를 고려했을 경우, 제조 가마를 직화로 가열하여 제조하는 공정으로 제조하는 것은 곤란하다. 나아가서는, 균일하게 탈수된 시안산염 또는 이소시안산염을 얻는 것이 어렵다.As a method of dehydration of cyanate or isocyanate, a method of dehydration by heating under a direct fire under reduced pressure is known. In addition, when implementation at the industrial level is considered, it is difficult to manufacture by a process of heating a manufacturing kiln by direct fire. Furthermore, it is difficult to obtain uniformly dehydrated cyanate or isocyanate.
또한, 특허문헌 2 의 방법에 있어서, 반응 촉진제, 용제에 대하여 직화로 가열했을 경우, 열 분해를 회피하면서 탈수하는 것은 곤란하다.Moreover, in the method of patent document 2, when heating with direct fire with respect to a reaction promoter and a solvent, it is difficult to dehydrate, avoiding thermal decomposition.
그 밖의 탈수 방법으로는, 몰레큘러 시브스, 활성 백토, 실리카 겔 등의 고체 흡착제를 사용한 탈수 방법을 들 수 있다. 그러나, 시안산염 또는 이소시안산염, 반응 촉진제, 용제로 이루어지는 용액은 슬러리 상태이며, 이 혼합 용액으로부터 고체 흡착제만을 분리하는 것이 곤란하다. 고체 흡착제가 잔존한 상태에서 할로겐화실란 화합물과 반응시켰을 경우, 고체 흡착제에 포함되는 물과 반응하여, 수율 및/또는 순도의 저하로 연결된다.As another dehydration method, the dehydration method using solid adsorbents, such as molecular sieves, activated clay, and silica gel, is mentioned. However, a solution comprising cyanate or isocyanate, a reaction accelerator, and a solvent is in a slurry state, and it is difficult to separate only the solid adsorbent from the mixed solution. When the solid adsorbent is reacted with the halogenated silane compound while the solid adsorbent remains, it reacts with water contained in the solid adsorbent, leading to a decrease in yield and/or purity.
보다 고품질의 규소 산화물 피막을 얻기 위해서, 단량체의 순도가 높은 규소이소시아네이트 화합물 함유 조성물이 요구되고 있고, 이러한 규소이소시아네이트 화합물 함유 조성물을 제조하기 위한 새로운 제조 방법의 개발이 요구되고 있다.In order to obtain a higher quality silicon oxide film, a composition containing a silicon isocyanate compound with high monomer purity is required, and development of a new manufacturing method for manufacturing such a composition containing a silicon isocyanate compound is required.
