2-Chloro-4-nitrobenzoic asidhi CAS 99-60-5 Kushandisa

Inowanikwa neklorini uye oxidation yep-nitrotoluene. Isa p-nitrotoluene mu reactor yakaoma, mushure mekupisa nekunyunguduka, wedzera iron wire uye iodine flakes, pa58-62 â, pfuura yakaenzana huwandu hwechlorine gasi, geza nemvura inopisa, neutralize ne sodium carbonate, uye udira mukati. ice water , yakamutswa kuti iparadzanise kunze makristasi, yakasefa kubvisa mvura, uye yakaomeswa mumumvuri kuwana 2-chloro-4-nitrotoluene. Wobva wawedzera 25 nguva dze 1-2% sodium hydroxide solution mu 2-chloro-4-nitrotoluene, kupisa kusvika kuvira Chemicalbook, pasi pesimba rinokurudzira, zvishoma nezvishoma wedzera potassium permanganate, chengetedza tembiricha iri pa100±1â, Mushure mekuwedzera, ramba uchiwedzera. kurunga, reflux kwe30min, rega kutonhorera, uye bvisa manganese dioxide. Iyo filtrate yakagadziridzwa pH 1-2 ine hydrochloric acid, iyo precipitate yakashambidzwa nemvura yechando, yakasvibiswa uye yakaomeswa pa80 ° C kuti iwane chigadzirwa. Iko chlorination operation inogonawo kuitwa pamberi peferric chloride, uye ichiri kupfuudza chlorine pa58-62 ° C. Kuwanda kwegoho reklorini uye oxidation inenge 70%.
