Iyiphi indlela yokulungiselela ukusebenza kahle okuphezulu kwe-Chlorempenthrin powder eluhlaza

I-Chlorempenthrinuhlobo olusha lwezinambuzane ze-pyrethroid olusebenza kahle kakhulu kanye nobuthi obuphansi, obunomthelela omuhle omiyane, izimpukane namaphela.Ifaka umfutho we-vapor ophezulu, ukuguquguquka okuhle namandla okubulala aqinile. Ingakwazi ukuwisa izinambuzane ngokushesha, ikakhulukazi uma ifuthwe noma ifuthwe, umphumela wokungqongqoza ubaluleke kakhulu.

Ukulungiselela

Indlela yokulungiselela ukusebenza kahle kakhuluI-ChlorempenthrinImpushana eluhlaza ihlukaniswe ngezinyathelo ezintathu ngokulandelana:

Emkhunjini wokusabela ofakwe i-condenser ye-reflux, ukugqugquzela, ukudonsa, ukufudumeza nokupholisa, i-200g ye-dichloroethane ne-200g ye-sodium acetylene yengezwe. Ngemuva kokuhlanganisa nokupholisa ku-10℃, i-30g ye-sodium hydroxide yengezwe kancane kancane cishe ngehora elingu-1. Khona-ke izinga lokushisa lakhuphuka laba ngu-50℃, kanye ne-100g ye-valenal yehliswa amahora angu-2. Ngemuva kokunciphisa, izinga lokushisa ligcinwa amahora angu-10, futhi ukusabela kwaqedwa. Engeza u-100g wamanzi we-hydrolysis, uhlukanise isigaba se-organic, ukugeza i-asidi namanzi ugeze isigaba se-organic, usule nge-sodium sulfate, bese uyincibilikisa ukuze uthole u-120g we-acetylene amyl alcohol. Indawo yokubilisa: 140-160℃, okuqukethwe: 98%, isivuno: 94.8%.

(2)Chaza u-62g we-acetylene amyl alcohol kusukela esinyathelweni sangaphambilini ku-460g we-toluene, engeza u-0.1g we-triethylamine njengesisusa, gudluza futhi uphole kuye ku-5.℃, bese uphonsa ku-116g we-all-trans DV inulyl chloride amahora angu-2. Ngemuva kokuqedwa kokwengeza, gcina ku-20℃amahora angu-6 futhi ukusabela sekuphelile. Amanzi ahlanzwa kabili, futhi isincibilikisi satholwa ngokuchithwa koketshezi olusabelayo ukuze kutholwe uwoyela ongahluziwe we-chlorenyl pyrethroid. Isivuno sikawoyela ongahluziwe sasingamagremu angu-157, nesivuno esingu-95%.

(3) Chaza u-100g we-Chlorempenthrin ongahluziwe ku-200g we-isopropanol, engeza u-0.1g we-catalyst triethylamine, upholile ku-5℃, gqugquzela futhi ucwebezele amahora angu-6, i-centrifuge futhi ukhiphe impahla, bese usula impushana yasekuqaleni ukuze uthole ukusebenza kahle okuphezulu kwe-chlorenethrin powder eluhlaza.
