Description
본 발명은 1,2,3,4-테트라히드로-9,10-안트라센-디올을 니트로화 함으로서 5-또는 6-모노니트로-1,2,3,4-테트라히드로-안트라퀴논 유도체를 얻음에 관한 것으로 그 출발원료로 1,2,3,4-테트라히드로-9,10-안트라센-디올을 사용하여 니트로화 함을 요지 및 특징으로 하는 방법에 관한 것이다.The present invention provides a 5- or 6-mononitro-1,2,3,4-tetrahydro-anthraquinone derivative by nitrating 1,2,3,4-tetrahydro-9,10-anthracene-diol. And a method characterized by nitrating using 1,2,3,4-tetrahydro-9,10-anthracene-diol as its starting material.
이들의 유도체류는 안트라퀴논의 α 또는 β 위치가 니트로화된 안트라퀴논의 모노니트로 유도체류를 제조함에 사용할 수 있는 중간물이다.These derivatives are intermediates that can be used to prepare mononitro derivatives of anthraquinone in which the α or β position of the anthraquinone is nitrated.
위에서 말한 물질 즉 α- 및 β-모노니트로-안트라퀴논은 염료의 생산하는 공업적 분야에서는 대단히 중요한 중간물이다. α-니트로-안트라퀴논이 안트라퀴논을 니트로화 함에 의하여 제조됨은 이미 잘 알려진 것이다.The above-mentioned materials, namely α- and β-mononitro-anthraquinones, are very important intermediates in the industrial field of producing dyes. It is well known that α-nitro-anthraquinones are prepared by nitrating anthraquinones.
그러나 이 공지의 방법은 반드시 분리하여야 하고 또 바람직하지 못한 디니트로-유도체를 부차적으로 생성하는 폐단이 있다. 2-니트로-1,4,4a,9a-안트라퀴논은 1,4,4a,9a-테트라히드로-안트라퀴논을 니트로화 함으로서도 제조된다(일본특허 공개공보 77,108,429 참조). 그러나 이 방법인 경우는 α-니트로-안트라퀴논을 얻을 수 있는 모노니트로 유도체는 생성되지 아니한다.However, this known method must be isolated and there is a closure which results in the generation of undesirable dinitro-derivatives. 2-nitro-1,4,4a, 9a-anthraquinone is also prepared by nitrating 1,4,4a, 9a-tetrahydro-anthraquinone (see Japanese Patent Laid-Open No. 77,108,429). However, in this method, no mononitro derivatives capable of obtaining α-nitro-anthraquinone are produced.
발명자는 1,2,3,4-테트라히드로-9,10-안트라센-디올을 니트로화함에 의하여 5 및 6 위치의 어느 하나가 모노니트로화된 1,2,3,4-테트라히드로-안트라퀴논을 현저한 고수률로 또 선택적으로 얻음을 발견하였는바 이를 수행함은 바로 본 발명의 목적이다.The inventors have described 1,2,3,4-tetrahydro-anthraquinone in which either of the 5 and 6 positions is mononitrated by nitrating 1,2,3,4-tetrahydro-9,10-anthracene-diol It has been found that is obtained selectively and selectively in a remarkably high yield is the object of the present invention.
5-니트로-1,2,3,4-테트라히드로-안트라퀴논과 6-니트로-1,2,3,4-테트라히드로-안트라퀴논 각기의 수득량은 반응조건에 따라 차이가 있으나, 1회의 반응에서 5-니트로-1,2,3,4-테트라히드로-안트라퀴논이 주요한 생성물이다.Yields of 5-nitro-1,2,3,4-tetrahydro-anthraquinone and 6-nitro-1,2,3,4-tetrahydro-anthraquinone are different depending on the reaction conditions. 5-nitro-1,2,3,4-tetrahydro-anthraquinone is the main product in the reaction.
1,2,3,4-테트라히드로-9,10-안트라센-디올은 1,4,4a,9a-테트라히드로-안트라퀴논을 수소첨가 및 이성화시킴을 요지로 하는 프랑스국 특허출원 1978. 6. 29일자 제78. 19465호에 의하여 유리하게 제조되는 것이며, 후자 즉 1,4,4a,9a-테트라히드로-안트라퀴논은-1,4-나프로퀴논과 부타디엔 상호간의 디일스 알더어반응(Diels slder reaction)에 의하여 제조하는 것이다.1,2,3,4-tetrahydro-9,10-anthracene-diol is a French patent application filed on the subject of hydrogenation and isomerization of 1,4,4a, 9a-tetrahydro-anthraquinone. Article 29 of date 29. Produced advantageously by No. 19465, the latter, i.e., 1,4,4a, 9a-tetrahydro-anthraquinone, is a Diels slder reaction between -1,4-naproquinone and butadiene. To manufacture.
본 발명은 1,2,3,4-테트라히드로-9,10-안트라센-디올을 질산과 황산으로 되는 혼산 또는 순수한 질산으로 처리하여 반응시키는 것이다. 그리고 이 처리에서는 반응에 관여하지 아니하는 종류의 용매를 존재시키고서 처리할 수도 있다. 질산과 황산으로 되는 혼산으로 니트로화하는 경우에 사용하는 황산의 농도는 70%보다 많아야 하며, 90%를 초과한 황산을 사용함이 바람직하다.In the present invention, 1,2,3,4-tetrahydro-9,10-anthracene-diol is reacted by treatment with mixed or pure nitric acid consisting of nitric acid and sulfuric acid. In this treatment, the solvent may be treated by the presence of a solvent that is not involved in the reaction. In the case of nitration with a mixed acid consisting of nitric acid and sulfuric acid, the concentration of sulfuric acid used should be more than 70%, and it is preferable to use sulfuric acid exceeding 90%.
발연황산도 사용된다. 사용하는 질산의 농도는 사용하는 황산의 농도에 의하여 차이가 있는 것이나, 90%를 초과하는 것이 바람직하다. 질산만을 사용하여 니트로화하는 경우에 사용하는 질산의 농도는 적어도 90%를 초과하여야 하며, 적어도 98%를 초과하는 것으로 함이 바람직하다.Fuming sulfuric acid is also used. The concentration of nitric acid to be used differs depending on the concentration of sulfuric acid to be used, but it is preferably more than 90%. In the case of nitrification using only nitric acid, the concentration of nitric acid to be used should be at least 90%, preferably at least 98%.
니트로화의 반응온도는 0° 내지 50℃이며, 0° 내지 30℃가 더 바람직하다.The reaction temperature of nitration is 0 degrees-50 degreeC, and 0 degree-30 degreeC is more preferable.
5-니트로-1,2,3,4-테트라히드로-안트라퀴논은 6-니트로-1,2,3,4-테트라히드로-안트라퀴논 보다 용해성이 대단히 적으므로 이것은 순수한 상태의 것으로 분리수득하기가 극히 용이하다. 니트로화 반응을 질산과 황산의 혼산으로 시키는 경우에는 생성되는 5-니트로-1,2,3,4-테트라히드로-안트라퀴논이 반응액에 불용성이므로 단순히 여과함으로서 분리 수득되는 것이다.Since 5-nitro-1,2,3,4-tetrahydro-anthraquinone is much less soluble than 6-nitro-1,2,3,4-tetrahydro-anthraquinone, it is pure and difficult to obtain. Extremely easy When the nitration reaction is mixed with nitric acid and sulfuric acid, the resulting 5-nitro-1,2,3,4-tetrahydro-anthraquinone is insoluble in the reaction solution and is thus obtained separately by filtration.
그리고 5-니트로-1,2,3,4-테트라히드로-안트라퀴논과 6-니트로-테트라히드로-안트라퀴논과의 혼합물로부터는 적당한 용매로 재결정시킴에 의하여 순수한 5-니트로-1,2,3,4-테트라히드로-안트라퀴논을 분리 수득하는 것이다.And from 5-nitro-1,2,3,4-tetrahydro-anthraquinone and 6-nitro-tetrahydro-anthraquinone, by recrystallization with a suitable solvent, pure 5-nitro-1,2,3 To obtain, 4-tetrahydro-anthraquinone is separated.
