Ithini indlela yokulungiselela i-Chlorempenthrin powder eluhlaza esebenza kakuhle?

I-Chlorempenthrinluhlobo olutsha lwesibulali-zinambuzane se-pyrethroid esisebenza kakuhle kakhulu kwaye sinobuthi obuphantsi, esinefuthe elihle kwiingcongconi, iimpukane kunye namaphela.Inomphunga ophezulu, ukuguquguquka okuhle kunye namandla okubulala anamandla. Ingaziwisa ngokukhawuleza izinambuzane, ingakumbi xa itshizwa okanye itshizwa, umphumo wokuyiwisa ubaluleke ngakumbi.

Ukulungiselela

Indlela yokulungiselela esebenza kakuhle kakhuluI-Chlorempenthrinumgubo oluhlaza wahlulwe ngamanyathelo amathathu ngokulandelelana:

Kwisitya sokusabela esixhotyiswe nge-condenser yokuvuselela, ukuvuselela, ukongeza, ukufudumeza nokupholisa, kongezwe i-200g ye-dichloroethane kunye ne-200g ye-sodium acetylene. Emva kokuvuselela nokupholisa ukuya kwi-10℃, i-30g ye-sodium hydroxide yongezwa kancinci kancinci malunga neyure e-1. Emva koko ubushushu baphakanyiswa bafikelela kuma-50℃, kwaye i-100g ye-valenal yafakwa iiyure ezi-2. Emva kokuyidibanisa, ubushushu bagcinwa iiyure ezili-10, kwaye impendulo yagqitywa. Yongeza i-100g yamanzi ukuze i-hydrolysis ihlale, yahlule i-organic phase, uhlambe nge-asidi uze uhlambe i-organic phase ngamanzi, uyomise nge-sodium sulfate, uze uyinyibilikise ukuze ufumane i-120g ye-acetylene amyl alcohol. Iqondo lokubila: 140-160℃, umxholo: 98%, isivuno: 94.8%.

(2)Nyibilikisa i-62g ye-acetylene amyl alcohol kwi-460g ye-toluene, yongeza i-0.1g ye-triethylamine njenge-catalyst, uxube uze uyipholise ukuya kwi-5.℃, uze ufake i-116g ye-all-trans DV inulyl chloride iiyure ezi-2. Emva kokuba ukongeza kugqityiwe, gcina kwi-20℃kangangeeyure ezi-6 kwaye impendulo igqityiwe. Amanzi ahlanjwe kabini, kwaye isinyibilikisi safunyanwa ngokunyibilikisa ulwelo lwempendulo ukuze kufunyanwe ioyile eluhlaza ye-chlorenyl pyrethroid. Imveliso yeoyile eluhlaza yayiyi-157 grams, kunye nesivuno se-95%.

(3) Nyibilikisa i-100g ye-Chlorempenthrin eluhlaza kwi-200g ye-isopropanol, yongeza i-0.1g ye-catalyst triethylamine, uyipholise ukuya kwi-5℃, xuba uze udibanise i-crystallize iiyure ezi-6, udibanise i-centrifuge uze ukhuphe izinto, uze womise umgubo wokuqala ukuze ufumane umgubo oluhlaza we-chlorenethrin osebenza kakuhle.
