    • A process for the production of dinitrophenyl ethers having the general formula [III]: ##STR1## wherein, one of R.sub.1 and R.sub.2 is a nitro radical, and the other is a hydrogen atom or a straight-chain, branched-chain or cyclic, saturated or unsaturated hydrocarbon radical containing from 1 to 10 carbon atoms, and R.sub.3 is a radical selected from the group consisting of (i) a straight-chain, branched-chain or cyclic, saturated or unsaturated hydrocarbon radical containing from 2 to 10 carbon atoms, (ii) a straight-chain hydrocarbon radical having one phenyl group as a substituent and containing from 1 to 5 carbon atoms, (iii) a phenyl radical, and (iv) a phenyl radical with one or more than one substituents selected from the group consisting of a nitro group, a halogen group, a saturated or unsaturated hydrocarbon group containing from 1 to 5 carbon atoms and an alkoxy group containing from 1 to 4 carbon atoms, by reacting a compound represented by the formula [I]: ##STR2## wherein, R.sub.1 and R.sub.2 have the above-mentioned meanings, and a compound represented by the general formula [II]:R.sub.3 OH [II]wherein, R.sub.3 has the above-mentioned meaning, in the presence of an alkaline compound. This process has greater ease compared with the classical synthetic processes using a halogen compound intermediate.
    • 制备具有通式[III]的二硝基苯基醚的方法:其中,R1和R2之一是硝基,另一个是氢原子或直链,支链或环状的, 含有1至10个碳原子的饱和或不饱和烃基,R 3是选自(i)含有2至10个碳原子的直链,支链或环状,饱和或不饱和烃基的基团 ,(ii)具有一个苯基作为取代基且含有1至5个碳原子的直链烃基,(iii)苯基,和(iv)具有一个或多于一个取代基的苯基,所述取代基选自 通过使式[I]表示的化合物反应,由硝基,卤素基,含有1至5个碳原子的饱和或不饱和烃基和含有1至4个碳原子的烷氧基组成的基团: [I]其中,R1和R2 具有上述含义,和由通式[II]表示的化合物:R3OH [II]其中R3具有上述含义,在碱性化合物的存在下。 与使用卤素化合物中间体的经典合成方法相比,该方法更容易。
