Nubuhe buryo bwo gutegura uburyo bwiza bwa Chlorempenthrin ifu mbisi

Chlorempenthrinni ubwoko bushya bw’udukoko twangiza pyrethroid hamwe nubushobozi buke nuburozi buke, bufite ingaruka nziza kumubu, isazi ninkoko.Igaragaza umuvuduko mwinshi wumuyaga, guhindagurika kwiza nimbaraga zikomeye zo kwica. Irashobora gukubita udukoko vuba, cyane cyane iyo yatewe cyangwa yatewe, ingaruka zo gukomanga ni ngombwa.

Kwitegura

Uburyo bwo gutegura uburyo bwo gukora nezaChlorempenthrinifu mbisi igabanijwemo intambwe eshatu zikurikiranye:

Mu cyombo cya reaction cyashyizwemo kondereseri yo kugaruka, gukurura, guta ibyongeweho, gushyushya no gukonjesha, 200g ya dichloroethane na 200g ya sodium acetylene. Nyuma yo gukurura no gukonja kugeza 10℃, 30g ya sodium hydroxide yongewemo buhoro mumasaha 1. Hanyuma ubushyuhe bwazamutse bugera kuri 50℃, na 100g ya valenal yataye mumasaha 2. Nyuma yo guta ibyongeweho, ubushyuhe bwakomeje kumasaha 10, kandi reaction yararangiye. Ongeramo 100g y'amazi ya hydrolysis, tandukanya icyiciro kama, gukaraba aside hamwe namazi ukarabe kama kama, ukumisha sodium sulfate, hanyuma ukayashonga kugirango ubone 120g yinzoga ya acetylene amyl. Ingingo yo guteka: 140-160℃, ibirimo: 98%, umusaruro: 94.8%.

(2)Kuramo 62g ya alcool ya acetylene amyl uhereye kuntambwe ibanza muri 460g ya toluene, ongeramo 0.1g ya triethylamine nka catalizator, koga kandi ukonje kuri 5℃, hanyuma ugabanuke muri 116g ya trans-trans yose ya DV inulyl chloride mumasaha 2. Inyongera imaze kurangira, komeza kuri 20℃kumasaha 6 kandi reaction irarangiye. Amazi yogejwe kabiri, kandi umusemburo wagaruwe no gusenya amazi ya reaction kugirango ubone amavuta ya peteroli ya chlorenyl pyrethroid. Umusaruro wa peteroli wari garama 157, umusaruro wa 95%.

.℃, kubyutsa no korohereza amasaha 6, centrifuge hanyuma usohore ibikoresho, hanyuma wumishe ifu yumwimerere kugirango ubone ifu mbisi ya chlorenethrin ikora neza.
