Kodi njira yokonzekera ufa wosaphika wa Chlorempenthrin wothandiza kwambiri ndi iti?

Chlorempenthrinndi mtundu watsopano wa mankhwala ophera tizilombo otchedwa pyrethroid omwe amagwira ntchito bwino kwambiri komanso ali ndi poizoni wochepa, womwe umathandiza kwambiri pa udzudzu, ntchentche ndi mphemvu.Ili ndi mphamvu yochuluka ya nthunzi, kusinthasintha kwabwino komanso mphamvu yakupha. Imatha kugwetsa tizilombo mwachangu, makamaka ikapopedwa kapena kutsukidwa, mphamvu yogwetsa imakhala yofunika kwambiri.

Kukonzekera

Njira yokonzekera bwino kwambiriChlorempenthrinUfa wosaphika umagawidwa m'magawo atatu motsatizana:

Mu chotengera choyatsira mpweya chokhala ndi condenser yoti ichotse mpweya, kusakaniza, kugwetsa, kutentha ndi kuziziritsa, 200g ya dichloroethane ndi 200g ya sodium acetylene zinawonjezedwa. Pambuyo posakaniza ndi kuziziritsa mpaka 10g.℃, 30g ya sodium hydroxide inawonjezedwa pang'onopang'ono patatha ola limodzi. Kenako kutentha kunakwezedwa kufika pa 50℃, ndipo 100g ya valenal inalowetsedwa kwa maola awiri. Pambuyo powonjezera, kutentha kunasungidwa kwa maola 10, ndipo yankho linatha. Onjezani 100g ya madzi kuti hydrolysis ichitike, lekanitsani gawo la organic, sambitsani ndi asidi ndi madzi, sambitsani gawo la organic, liume ndi sodium sulfate, ndikusungunula kuti mupeze 120g ya acetylene amyl alcohol. Malo otentha: 140-160℃, zomwe zili: 98%, phindu: 94.8%.

(2)Sungunulani 62g ya acetylene amyl alcohol kuchokera pa sitepe yapitayi mu 460g ya toluene, onjezerani 0.1g ya triethylamine ngati chothandizira, sakanizani ndikuziziritsa mpaka 5℃, kenako tsanulirani 116g ya all-trans DV inulyl chloride kwa maola awiri. Mukamaliza kuwonjezera, sungani pa 20℃Kwa maola 6 ndipo yankho latha. Madziwo anatsukidwa kawiri, ndipo chosungunuliracho chinabwezeretsedwa mwa kuchotsa madzi oyambitsa kuti apeze mafuta osakonzedwa a chlorenyl pyrethroid. Mafuta osakonzedwa anali magalamu 157, ndi phindu la 95%.

(3) Sungunulani 100g ya Chlorempenthrin yosaphikidwa mu 200g ya isopropanol, onjezerani 0.1g ya catalyst triethylamine, muziziziritse mpaka 5℃, sakanizani ndi kusakaniza kwa maola 6, pukutani ndi kutulutsa zinthuzo, kenako muumitse ufa woyambirira kuti mupeze ufa wosaphika wa chlorenethrin wothandiza kwambiri.
