2 3 5-Trichloropyridine (CAS# 16063-70-0) Ulwazi
| intshayelelo | I-2,3, i-5-trichloropyridine yinto eqinileyo etyheli ekhanyayo kunye nekhemikhali ebalulekileyo ephakathi. I-2,3,5-trichloropyridine isabela nge-alkali yensimbi ye-hydroxide ukulungiselela i-3,5-dichloro-2-pyridine phenol, eyona nto ibalulekileyo yezinto ezibonakalayo zokwenziwa kwe-insecticidal mites kunye ne-herbicide oxaloether. I-2,3, i-5-trichloropyridine inokuthi iphinde ifakwe i-fluorinated ukuze idibanise i-2, i-3-difluoro-5-chloropyridine, eyona nto isisiseko sokwenziwa kwe-herbicide alkynurate. |
| ukulungiselela | I-60g ye-methanol yongezwa kwi-1000mL yeflask enemilomo emine, i-100g I-2,3,5,6-tetrachloropyridine kunye ne-31.7g ye-hydrazine hydrate yongezwa, iqondo lokushisa liye lanyuswa laya kwi-60-65 ℃, ukusabela kokugcina ubushushu kwenziwa malunga neeyure ze-2, ukusabela kugqityiwe, ubushushu behliswa. 0-5 ℃, ubushushu behliswa ukuya kwiyure enye, okuqinileyo kwahluzwa, kwaye okuqinileyo kwakuyi-2,3, I-5-trichlor6-hydrazinyl pyridine hydrate yomiswa ukuze ifumane i-101.6g ye-white solid and 96% isivuno kunye ne-98.5% umxholo. Yongeza i-100g I-2,3,5-trichloro 6-hydrazinyl pyridine hydrate, 50g ye-5% ye-sodium hydroxide isisombululo se-aqueous ukuya kwi-1000ml yebhotile yomlomo emine, phakamisa ubushushu ukuya kwi-70-75 ℃, yongeza i-387.6g ye-10% ye-sodium hypochlorite isisombululo se-aqueous dropwise, gcina iqondo lobushushu kwi-70-75 ℃, uphendule iyure enye, uphelise impendulo, ipholile ukuya ku-5-10 ℃, ivuse iyure e-1, ihluzo ukufumana i-2,3, i-5-trichloropyridine ekrwada idityanisiwe phantsi koxinzelelo oluncitshisiweyo lokufumana imveliso, eqinileyo etyheli ekhanyayo enesivuno sama-95% kunye ne umxholo wama-98%. |
Bhala umyalezo wakho apha kwaye uwuthumele kuthi
