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

Chlorempenthrinwaa nooc cusub oo ah sunta cayayaanka ee pyrethroid oo leh hufnaan sare iyo sun yar, taasoo saameyn wanaagsan ku leh kaneecada, duqsiga iyo baranbarada.Waxay leedahay cadaadis uumi sare, isbeddel wanaagsan iyo awood dil oo xooggan. Waxay si dhakhso ah u burburin kartaa cayayaanka, gaar ahaan marka la buufiyo ama la buufiyo, saameynta garaaca ayaa aad u weyn.

Diyaarinta

Habka diyaarinta ee waxtarka sare lehChlorempenthrinBudada cayriin waxay u qaybsantaa saddex tallaabo oo isku xigxiga:

Weel falcelin ah oo lagu rakibay kondenser loogu talagalay dib-u-soo-celinta, walaaqidda, ku darista, kululaynta iyo qaboojinta, 200g oo dichloroethane ah iyo 200g oo sodium acetylene ah ayaa lagu daray. Ka dib markii la walaaqo oo la qaboojiyo ilaa 10℃, 30g oo sodium hydroxide ah ayaa si tartiib tartiib ah loogu daray qiyaastii 1 saac gudahood. Kadibna heerkulka ayaa kor loo qaaday ilaa 50℃, 100g oo valenal ah ayaa lagu shubay 2 saacadood. Ka dib markii lagu daray, heerkulka ayaa la ilaaliyay 10 saacadood, falcelintuna way dhammaatay. Ku dar 100g oo biyo ah si loo helo hydrolysis, kala saar marxaladda organic-ga, dhaqidda aashitada iyo biyo ku dhaq wejiga organic-ga, ku qalaji sodium sulfate, oo ku milmi si aad u hesho 120g oo acetylene amyl alcohol ah. Barta karkarinta: 140-160℃, waxa ku jira: 98%, wax soo saar: 94.8%.

(2)Ku milmi 62g oo acetylene amyl alcohol ah tallaabadii hore 460g oo toluene ah, ku dar 0.1g oo triethylamine ah oo ah kiciye, walaaq oo qabooji ilaa 5.℃, ka dibna ku rid 116g oo ah all-trans DV inulyl chloride muddo 2 saacadood ah. Ka dib marka lagu daro la dhammeeyo, ku hay 20℃muddo 6 saacadood ah falgalkuna wuu dhammaaday. Biyaha ayaa laba jeer la dhaqay, dareerahana waxaa lagu soo celiyay milanka dareeraha falgalka si loo helo saliid cayriin ah oo chlorenyl pyrethroid ah. Wax soo saarka saliidda cayriin wuxuu ahaa 157 garaam, iyadoo wax soo saarkeedu yahay 95%.

(3) Ku milmi 100g oo Chlorempenthrin cayriin ah 200g oo isopropanol ah, ku dar 0.1g oo kaalshiyam triethylamine ah, qabooji ilaa 5℃, walaaq oo ku shub biyo muddo 6 saacadood ah, ku shub centrifuge oo ka saar walaxda, ka dibna qalaji budada asalka ah si aad u hesho budo cayriin ah oo chlorenethrin ah oo waxtar sare leh.
