  • Process for producing 1,2-dialkoxy-3-fluorobenzene
    申请人:Qiu Mingjian
    公开号:US20090227817A1
    公开(公告)日:2009-09-10
    The present invention relates to a process for producing a 2-fluoro-6-halophenol as an intermediate; a process for producing a 2-alkoxy-3-fluorophenol and further a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; a second process for producing a 1,2-dialkoxy-3-fluorobenzene from the 2-fluoro-6-halophenol; and a 2-alkoxy-3-fluorophenol. The 2-fluoro-6-halophenol can be obtained using a 2-fluorophenol as a starting material and through a sulfonation reaction, a halogenation reaction, and a deprotection reaction. The 2-fluoro-6-halophenol is alkyl-etherified, and subsequently the halogen atom is converted into a hydroxyl group to obtain the 2-alkoxy-3-fluorophenol, which is further alkyl-etherified to thereby obtain the 1,2-dialkoxy-3-fluorobenzene. Alternatively, a 1,2-dialkoxy-3-fluorobenzene is also obtained by converting the halogen atom of the 2-fluoro-6-halophenol into a hydroxyl group to thereby form 3-fluorocatechol and subsequently alkyl-etherifying two hydroxyl groups thereof. The processes of the invention realize low production costs and high process yields, and thus are suitable for industrial production of a 1,2-dialkoxy-3-fluorobenzene.
    本发明涉及一种生产2-氟-6-卤苯酚作为中间体的过程;一种从2-氟-6-卤苯酚生产2-烷氧基-3-氟苯酚,进而从中生产1,2-二烷氧基-3-氟苯的过程;一种从2-氟-6-卤苯酚生产1,2-二烷氧基-3-氟苯的第二过程;以及2-烷氧基-3-氟苯酚。可以使用2-氟苯酚作为起始原料,通过磺化反应、卤代反应和去保护反应获得2-氟-6-卤苯酚。将2-氟-6-卤苯酚烷基醚化,随后将卤原子转化为羟基以获得2-烷氧基-3-氟苯酚,进一步烷基醚化以获得1,2-二烷氧基-3-氟苯。另外,通过将2-氟-6-卤苯酚的卤原子转化为羟基从而形成3-氟邻苯二酚,随后烷基醚化两个羟基,也可以获得1,2-二烷氧基-3-氟苯。本发明的工艺实现了低生产成本和高工艺产率,因此适用于工业生产1,2-二烷氧基-3-氟苯。

    The invention describes an improved method for producing halo-dialkoxybenzenes of formula (I) such as 1-fluoro-2, 3-dialkoxybenzene as well as 2-fluoro-1, 4-dialkoxybenzene, Formula (I) by reacting commercial 2-fluorophenol is reacted with an allyl halide in N-methylpyrrolidone (NMP) followed by rearranging the resultant 2-fluoroallylphenylether to form 2-allyl-6-fluorophenol and its para isomeric counterpart. This compound mixture is then directly alkylated to form isomeric substituted allyl alkoxybenzenes and subjected to isomerization to form the corresponding propenyl derivatives. All the above four steps are carried out without any workup except one filtration. 6-Fluoro-2-propenyl alkyl phenyl ether is separated from the other isomer by a fractional distillation in good yields. The isomers are oxidized to the corresponding benzaldehydes using oxidants in presence of a halo hydrocarbon solvent. The benzaldehydes is further oxidised with an organic or an inorganic peroxide in a halo hydrocarbon solvent to obtain the corresponding phenols, which is thereby alkylated to form compound of formula (I).
    该发明描述了一种改进的生产卤代二烷氧基苯的方法,其中化学式为(I),例如1-氟-2,3-二烷氧基苯和2-氟-1,4-二烷氧基苯。通过将商业2-氟苯酚与烯丙基卤化物在N-甲基吡咯烷酮(NMP)中反应,然后重排得到的2-氟烯丙基苯醚形成2-烯丙基-6-氟苯酚及其对位异构体。然后,将这种化合物混合物直接烷基化以形成异构的烯丙基烷氧基苯,并进行异构化以形成相应的丙烯基衍生物。所有以上四个步骤都在除一个过滤之外不进行任何处理。6-氟-2-丙烯基烷基苯醚通过分馏以高收率与其他异构体分离。这些异构体在存在卤代烃溶剂中使用氧化剂氧化为相应的苯甲醛。苯甲醛进一步在卤代烃溶剂中与有机或无机过氧化物氧化以获得相应的酚,然后烷基化以形成化合物的化学式(I)。
