Ubungozi Nokuphepha

Izimpawu Eziyingozi Xi - Irritant
Amakhodi Engozi R52/53 – Kuyingozi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini.
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha.
I-S37/39 – Gqoka amagilavu ​​afanelekile kanye nokuvikela iso/ubuso
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

2 3 5-Trichloropyridine (CAS# 16063-70-0) Ulwazi

isingeniso I-2,3, 5-trichloropyridine iqinile ephuzi ngokukhanyayo futhi iyikhemikhali ecolekileyo ephakathi nendawo. I-2,3,5-trichloropyridine ihlangana ne-alkali metal hydroxide ukuze ilungiselele i-3,5-dichloro-2-pyridine phenol, okuyingxenye ebalulekile yokwakhiwa kwezibungu zezinambuzane kanye ne-herbicide oxaloether. I-2,3, 5-trichloropyridine ingaphinda ifakwe i-fluorinated ukuze ihlanganise i-2, 3-difluoro-5-chloropyridine, okuyisisekelo sokusetshenziswa kwe-herbicide alkynurate.
ukulungiselela I-60g ye-methanol yengezwe ku-1000mL yeflask enemilomo emine, i-100g
I-2,3,5,6-tetrachloropyridine kanye ne-31.7g ye-hydrazine hydrate yengezwa, izinga lokushisa lenyuka laya ku-60-65 ℃, ukusabela kokugcina ukushisa kwenziwa cishe amahora ama-2, ukusabela kuqediwe, izinga lokushisa lehliswa 0-5 ℃, izinga lokushisa lehliswa laya ehoreni elingu-1, okuqinile kwahlungwa, futhi okuqinile kwaba ngu-2,3, I-5-trichlor6-hydrazinyl pyridine hydrate yomiswa ukuze kutholwe u-101.6g wokuqinile okumhlophe ngesivuno esingu-96% kanye nokuqukethwe okungu-98.5%. Engeza u-100g
2,3,5-trichloro 6-hydrazinyl pyridine hydrate, 50g we-5% sodium hydroxide isixazululo samanzi ku-1000ml webhodlela lemilomo emine, akhuphule izinga lokushisa libe ku-70-75 ℃, engeza u-387.6g we-10% ye-sodium hypochlorite yesisombululo samanzi esidonsa phansi, gcina izinga lokushisa ku-70-75 ℃, sabela ihora elingu-1, uqedele ukusabela, kuphole ku-5-10 ℃, gudluza ihora elingu-1, ukuhlunga ukuze uthole u-2,3, i-5-trichloropyridine engahluziwe igaywa ngaphansi kwengcindezi encishisiwe ukuze uthole umkhiqizo, okuqinile okuphuzi okukhanyayo okunomkhiqizo we-95% kanye okuqukethwe ngu-98%.
