Waa maxay habka diyaarinta ee waxtarka sare leh ee Chlorempentrin budada cayriin

Chlorempentrinwaa nooc cusub oo ah sunta cayayaanka pyrethroid oo leh waxtar sare iyo suntu hooseyso, taas oo saameyn wanaagsan ku leh kaneecada, duqsiga iyo baranbarada.Waxa uu leeyahay cadaadis sare oo uumiga, isbeddel wanaagsan iyo awood dil oo xooggan. Waxay si dhakhso ah u garaaci kartaa cayayaanka, gaar ahaan marka la buufiyo ama la qiiqo, saameynta garaacista ayaa aad muhiim u ah.

Diyaarinta

Habka diyaarinta ee waxtarka sare lehChlorempentrinbudada cayriin waxay u qaybsantaa saddex tallaabo oo isku xigta:

Weel falcelin ah oo ku qalabaysan kondenser-ka dib-u-soo-celinta, walaaqaya, isku-darka hoos u dhaca, kuleylka iyo qaboojinta, 200g oo dichloroethane ah iyo 200g oo sodium acetylene ah ayaa lagu daray. Ka dib markaad walaaqdo oo qaboojiso 10℃, 30g oo sodium hydroxide ah ayaa si tartiib ah loogu daray ilaa 1 saac. Kadibna heerkulku waxa la gaadhsiiyay 50℃100 garaam oo valenal ah ayaa lagu riday 2 saacadood. Ka dib marka la isku daro, heerkulka ayaa la ilaaliyaa 10 saacadood, falcelinta ayaa la dhammeeyey. Ku dar 100g oo biyo ah oo loogu talagalay hydrolysis, kala saar wajiga organic, dhaq aashitada iyo biyaha ku dhaq wajiga organic, ku qalaji sodium sulfate, oo ku milmi si aad u hesho 120g oo ah aalkolada acetylene amyl. Barta karkarinta: 140-160℃, content: 98%, dhalid: 94.8%.

(2)Milaan 62g oo aalkolada acetylene amyl ah talaabadii hore ee 460g ee toluene, ku dar 0.1g of triethylamine si ay u kiciso, walaaq oo qabooji 5℃, ka dibna ku rid 116g oo dhan-trans DV inulyl chloride ilaa 2 saacadood. Ka dib marka isku-darka la dhammeeyo, ku hay 20℃6 saacadood oo falcelintu way dhammaatay. Biyaha ayaa la dhaqay laba jeer, dareeraha waxaa lagu soo celiyay dareeraha falcelinta si ay u helaan saliid cayriin oo ah chlorenyl pyrethroid. Saliida ceyriinka soo saarta waxa ay ahayd 157 garaam, iyada oo wax-soo-saarkeedu dhan yahay 95%.

(3) Ku mil 100g oo Chlorempenthrin cayriin ah 200g oo isopropanol ah, ku dar 0.1g oo ah triethylamine kicinta, qabow ilaa 5℃, walaaq oo crystallize ilaa 6 saacadood, sentrifuge oo bixi walxaha, ka dibna qalaji budada asalka ah si aad u hesho budada cayriin ee chlorenethrin oo tayo sare leh.
