2-Chloro-4-nitrobenzoic acid CAS 99-60-5

Believe Chemical ndiwopanga China 2-Chloro-4-nitrobenzoic acid CAS 99-60-5 wopanga, wogulitsa ndi wogulitsa kunja. Kutsatira kufunafuna zinthu zabwino kwambiri, kotero kuti 2-Chloro-4-nitrobenzoic acid CAS 99-60-5 yakhutitsidwa ndi makasitomala ambiri. Shandong Khulupirirani

Ndife abwino pa ubwino wa mankhwala mankhwala m'munda. Zogulitsa zathu zimatumizidwa ku Europe, United States, Japan, South Korea, Southeast Asia ndi mayiko ena ndi zigawo. Ndi sayansi ndi luso monga kalozera, kukhulupirika monga maziko, khalidwe moyo, ndi kudalira lingaliro ogwira ntchito za luso ndi chitukuko, ife moona mtima tikuyembekeza kukhazikitsa kusinthanitsa ndi mgwirizano waukulu ndi makasitomala m'nyumba ndi akunja kulenga chitukuko!

2-Chloro-4-nitrobenzoic acid CAS 99-60-5 Ntchito

Amapezeka ndi chlorination ndi okosijeni wa p-nitrotoluene. Ikani p-nitrotoluene mu riyakitala youma, mutatha kutentha ndi kusungunuka, onjezerani waya wachitsulo ndi ayodini flakes, pa 58-62 â, perekani equimolar kuchuluka kwa chlorine mpweya, kusamba ndi madzi otentha, neutralize ndi sodium carbonate, ndi kutsanulira mu. madzi oundana, osonkhezeredwa kuti alekanitse makhiristo, amasefedwa kuchotsa madzi, ndi kuwuma mumthunzi kuti apeze 2-chloro-4-nitrotoluene. Kenaka yikani 25 nthawi za 1-2% sodium hydroxide solution mu 2-chloro-4-nitrotoluene, kutentha mpaka kuwira Chemicalbook, pansi pa kusonkhezera mwamphamvu, pang'onopang'ono kuwonjezera potaziyamu permanganate, kusunga kutentha kwa 100±1â , Pambuyo powonjezera, pitirizani. kusonkhezera, reflux kwa 30min, lolani kuti kuziziritsa, ndi kuchotsa manganese dioxide. Filtrate inasinthidwa kukhala pH 1-2 ndi hydrochloric acid, mpweyawo unatsukidwa ndi madzi oundana, umasefedwa ndikuwumitsa pa 80 ° C kuti upeze mankhwala. Opaleshoni ya klorini imathanso kuchitika pamaso pa ferric chloride, ndikupitilira chlorine pa 58-62 ° C. Zokolola zonse za chlorination ndi oxidation ndi pafupifupi 70%.
