Iyintoni indlela yokulungiselela i-high-efficiency Chlorempenthrin powder eluhlaza

Chlorempenthrinluhlobo olutsha lwe-pyrethroid insecticide kunye nokusebenza okuphezulu kunye netyhefu ephantsi, enefuthe elihle kwiingcongconi, iimpukane kunye namaphela.Ibonisa uxinzelelo oluphezulu lomphunga, ukuguquguquka okulungileyo kunye namandla okubulala anamandla. Ingaziwisa izitshabalalisi ngokukhawuleza, ngakumbi xa itshizwe okanye ifumiwe, umphumo wokunkqonkqoza ubaluleke kakhulu.

Ukulungiselela

Indlela yokulungiselela ukusebenza kakuhleChlorempenthrinumgubo okrwada wohlulwe ngokwamanqanaba amathathu ngokulandelelana:

Kwisitya sokusabela esixhotyiswe nge-condenser ye-reflux, ukuvuselela, ukulahla ukongezwa, ukufudumeza kunye nokupholisa, i-200g ye-dichloroethane kunye ne-200g ye-sodium acetylene yongezwa. Emva kokuvuselela kunye nokupholisa ukuya kwi-10℃, I-30g ye-sodium hydroxide yongezwa ngokukhawuleza malunga neyure ye-1. Emva koko iqondo lobushushu lanyuswa laya kutsho kuma-50℃, kunye ne-100g ye-valenal yachithwa kwiiyure ezi-2. Emva kokulahla ukongeza, ubushushu bugcinwe iiyure ezili-10, kwaye ukusabela kwagqitywa. Yongeza i-100g yamanzi kwi-hydrolysis, yahlula isigaba se-organic, ukuhlamba i-asidi kunye namanzi ukuhlamba isigaba se-organic, uyomise nge-sodium sulfate, kwaye uyinyibilikise ukufumana i-120g ye-acetylene amyl alcohol. Indawo yokubilisa: 140-160℃, umxholo: 98%, isivuno: 94,8%.

(2)Dissolve i-62g ye-acetylene amyl alcohol ukusuka kwinqanaba langaphambili kwi-460g ye-toluene, yongeza i-0.1g ye-triethylamine njenge-catalyst, ugxobhoze kwaye upholile ukuya kwi-5℃, emva koko ulahle kwi-116g ye-all-trans DV inulyl chloride kwiiyure ze-2. Emva kokuba ukongeza kugqityiwe, gcina kwi-20℃iiyure ezi-6 kwaye impendulo igqityiwe. Amanzi ahlanjwa kabini, kwaye i-solvent yafunyanwa ngokuchithwa kolwelo olusabelayo ukufumana ioli ekrwada ye-chlorenyl pyrethroid. Isivuno se-oyile ekrwada ibiyi-157 grams, nesivuno se-95%.

(3) Ukunyibilikisa i-100g yeChlorempenthrin ekrwada kwi-200g ye-isopropanol, yongeza i-0.1g ye-catalyst triethylamine, ipholile kwi-5℃, ugxobhoze kwaye ugxininise kwiiyure ze-6, i-centrifuge kwaye ukhuphe izinto eziphathekayo, uze uyomise i-powder yasekuqaleni ukufumana i-high-efficiency chlorenethrin powder eluhlaza.
