Iyiphi indlela yokulungiselela i-Chlorempenthrin eluhlaza esebenza kahle kakhulu

I-Chlorempenthrinuhlobo olusha lwesibulala-zinambuzane se-pyrethroid esisebenza kahle kakhulu futhi sinobuthi obuphansi, esinomphumela omuhle komiyane, izimpukane namaphela.Inomfutho ophezulu womusi, ukuguquguquka okuhle kanye namandla okubulala aqinile. Ingawisa izinambuzane ngokushesha, ikakhulukazi uma ifuthwa noma ifuthwa, umphumela wokugoba ubaluleke kakhulu.

Ukulungiselela

Indlela yokulungiselela esebenza kahle kakhuluI-ChlorempenthrinImpuphu eluhlaza ihlukaniswe ngezinyathelo ezintathu ngokulandelana:

Esitsheni sokusabela esifakwe i-condenser yokuvuselela, ukuvuselela, ukwengeza, ukupholisa, ukuhlanganisa, ukufudumala nokupholisa, kufakwe amagremu angu-200 e-dichloroethane kanye namagremu angu-200 e-sodium acetylene. Ngemva kokuvuselela nokupholisa ku-10℃, amagremu angu-30 e-sodium hydroxide afakwa kancane kancane cishe ngehora elilodwa. Bese izinga lokushisa lenyuswa laya ku-50℃, futhi i-100g ye-valenal yafakwa amahora ama-2. Ngemva kokuyibeka, izinga lokushisa lagcinwa amahora ayi-10, futhi ukusabela kwaqedwa. Engeza i-100g yamanzi ukuze i-hydrolysis ihlale, hlukanisa isigaba se-organic, ugeze nge-acid bese ugeza isigaba se-organic ngamanzi, womise nge-sodium sulfate, bese uyincibilikisa ukuze uthole i-120g ye-acetylene amyl alcohol. Iphuzu lokubila: 140-160℃, okuqukethwe: 98%, isivuno: 94.8%.

(2)Ncibilikisa u-62g we-acetylene amyl alcohol esinyathelweni sangaphambilini ku-460g we-toluene, engeza u-0.1g we-triethylamine njenge-catalyst, uvuselele bese upholisa ku-5.℃, bese ufaka u-116g we-all-trans DV inulyl chloride amahora ama-2. Ngemva kokuthi ukwengeza sekuqediwe, gcina ku-20℃Amahora ayi-6 bese ukusabela sekuqediwe. Amanzi agezwa kabili, futhi isinyibilikisi satholwa ngokususa uketshezi lokusabela ukuze kutholakale uwoyela ongahluziwe we-chlorenyl pyrethroid. Isivuno samafutha angahluziwe sasingamagremu ayi-157, kanye nesivuno esingu-95%.

(3) Ncibilikisa i-100g ye-Chlorempenthrin eluhlaza ku-200g ye-isopropanol, engeza u-0.1g we-catalyst triethylamine, uphole ku-5℃, hlanganisa bese uqinisa i-crystal amahora ayi-6, uhlanganise i-centrifuge bese ukhipha izinto, bese womisa i-powder yokuqala ukuze uthole i-chlorenethrin eluhlaza esebenza kahle kakhulu.
