Description
본 발명은 용매로 특정한 복합용매를 사용함으로서 삼할로겐화인화합물과 히드록시가 치환된 방향족 화합물로부터 산화방지제인 트리아릴포스파이트를 고수율로 제조하는 방법에 관한 것이다.The present invention relates to a method of producing triaryl phosphite, an antioxidant, from a phosphorus trihalide compound and a hydroxy substituted aromatic compound in a high yield by using a specific complex solvent as a solvent.
일반적으로 트리아릴포스파이트는 삼할로겐화인과 히드록시 치환방향족 화합물과 반응시켜 제조하게 되며, 특히 아릴기를 치환시킨 히드록시기 화합물을 반응시키는 경우에는 반응성이 낮으므로 130℃의 고온에서 반응시키지 않으면 안된다.In general, triaryl phosphite is prepared by reacting a phosphorus trihalide with a hydroxy substituted aromatic compound. In particular, when the aryl group-substituted hydroxy group compound is reacted, the triaryl phosphite must be reacted at a high temperature of 130 ° C.
그러나 고온에서 장시간 반응시켜도 완전한 반응이 이루어지기는 불충분하며, 반응결과 모노-, 디- 및 트리-아릴포스파이트 등의 혼합물이 얻어진다.However, even after prolonged reaction at high temperature, a complete reaction is insufficient. As a result, a mixture of mono-, di- and tri-aryl phosphites is obtained.
종래 트리아릴포스파이트를 제조하는 방법으로는 일본 공개특허 소 54-30140호를 들 수 있는데, 이 방법에서는 삼할로겐화인과 ROH(식중 R은 아릴기, 알킬기, 사이크로알킬기, 아릴 또는 알킬기의 1종 또는 2종 이상의 기로 치환시킨 아릴기를 의미)로 표현되는 히드록시 치환방향족 화합물을 0,005~5몰%의 아민, 암모늄염, 카르복시산 등의 촉매하에서, 크실렌이 단독용매를 사용하여 트리아릴포스파이트를 제조하는 방법을 제시하고 있다.A conventional method for preparing triaryl phosphite is Japanese Patent Application Laid-Open No. 54-30140, in which phosphorus trihalide and ROH (wherein R is an aryl group, an alkyl group, a cycloalkyl group, an aryl or an alkyl group) Xylene is a triaryl phosphite using a single solvent of 0,005 to 5 mol% of a hydroxy substituted aromatic compound represented by an aryl group substituted with a species or two or more groups) under a catalyst such as amine, ammonium salt, or carboxylic acid. How to do it.
따라서 수율을 높이기 위하여 촉매로서 피리딘과 같은 질소화합물을 사용한 예가 소련 특허 제488821호에 있으나, 어느 정도의 반응성은 증가하지만 역시 크게 효과가 있는 것은 아니었으며, 특히 치환된 아릴을 사용하면 디-혹은 트리아릴포스파이트의 혼합물이 얻어지므로 역시 트리아릴포스파이트가 낮은 수율로 얻어지게 되며, 염의 침전으로 교반이 어려워진다.Thus, there is an example of using a nitrogen compound such as pyridine as a catalyst to increase the yield in US Pat. No. 488821, but the degree of reactivity is increased but also not very effective, especially when substituted aryl is used to di- or tree Since a mixture of arylphosphites is obtained, triaryl phosphites are also obtained in low yields, and the precipitation of salts makes stirring difficult.
그러나 이 방법으로 제조한 트리아릴포스파이트는 수율이 60% 정도로 매우 저조하였다.However, the triaryl phosphite prepared by this method was very low yield of about 60%.
따라서 본 발명의 목적은 삼할로겐화인과 히드록시 치환방향족화합물로부터 보다 낮은 반응온도에서 고수율로 트리아릴포스파이트를 제조하는 방법을 제공하고자 하는 것이다.It is therefore an object of the present invention to provide a process for the production of triaryl phosphites in high yield at lower reaction temperatures from phosphorus trihalide and hydroxy substituted aromatic compounds.
즉, 본 발명은 삼할로겐화인과 히드록시 치환방향족화합물을 테트라메틸헥사메틸렌디아민과 방향족화합물의 복합용매하에서 50~90℃로 반응시켜 다음 구조식(I)로 표시되는 트리아릴포스파이트를 제조하는 방법이다.That is, the present invention is a method for producing a triaryl phosphite represented by the following structural formula (I) by reacting a phosphorus trihalide hydroxy substituted aromatic compound at 50 ~ 90 ℃ in a complex solvent of tetramethylhexamethylenediamine and an aromatic compound to be.
[-R-O-]3, P……………………………………………………(I)[-RO-] 3 , P... … … … … … … … … … … … … … … … … … … … (I)
(여기서, R은 아릴기, 직쇄 가지를 갖는 알킬기, 1종 혹은 2종의 치환기를 갖는 방향족화합물을 나타낸다.)(Wherein R represents an aryl group, an alkyl group having a linear branch, and an aromatic compound having one or two substituents.)
본 발명에서 사용하는 복합용매 성분중 테트라메틸헥사메틸렌디아민(TMHD)은 촉매겸 반응용매로 사용되어 반응속도를 증가시켜 주며, 방향족 용매를 동시에 사용하므로 상승효과(SYNERGY EFFECT)에 의해 50~90℃의 낮은 온도하에서 반응속도가 상승할 뿐 아니라 부생성물이 거의 없는 80~95% 수율의 순수한 트리아릴포스파이트가 제조된다.Tetramethylhexamethylenediamine (TMHD) in the composite solvent component used in the present invention is used as a catalyst and a reaction solvent to increase the reaction rate, 50-90 ℃ by the synergistic effect (SYNERGY EFFECT) by using an aromatic solvent at the same time Under the low temperature of, the reaction rate is increased, and pure triaryl phosphite is produced in 80-95% yield with little byproduct.
본 발명에서는 방향족화합물로는 벤젠, 톨루엔, 크실렌, 에틸벤젠, 메톡시벤젠 등을 사용할 수 있다.In the present invention, as the aromatic compound, benzene, toluene, xylene, ethylbenzene, methoxybenzene and the like can be used.
용매인 테트라메틸헥사메틸렌디아민과 방향족화합물의 사용비는 무게비로 2 : 1이며, 이 수치보다 방향족화합물을 더 사용하면 반응 부생성물이 제조되어 수율이 떨어지게 되며, 테트라메틸헥사메틸렌디아민을 더 사용하게 되면 염의 침전이 생성되어 교반이 어려원진다.The use ratio of tetramethylhexamethylenediamine, which is a solvent, and an aromatic compound is 2: 1 by weight, and when the aromatic compound is used more than this value, the reaction by-products are produced, and the yield is decreased, and the use of tetramethylhexamethylenediamine is more preferable. Precipitation of salts is then generated, making stirring difficult.
본 발명에 의해 제조된 트리아릴포스파이트는 우수한 산화방지효과가 있으므로 열가소성 고분자의 자외선 안정제로 널리 사용된다.The triaryl phosphite prepared by the present invention has excellent anti-oxidation effect and thus is widely used as an ultraviolet light stabilizer of thermoplastic polymers.
이하, 본 발명을 실시예에 의거 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.
단, 본 발명이 실시예로 국한되는 것은 아니다.However, the present invention is not limited to the examples.
