Chlorempenthrinimhando itsva yemishonga yezvipembenene inonzi pyrethroid inoshanda zvakanyanya uye ine chepfu shoma, iyo ine mhedzisiro yakanaka paumhutu, nhunzi nemapete.Ine simba guru remhepo, kushanduka-shanduka kwakanaka uye simba guru rekuuraya. Inogona kudonhedza zvipembenene nekukurumidza, kunyanya kana ikapfapfaidzwa kana kupiswa, mhedzisiro yekudonhedza inonyanya kukosha.
Kugadzirira
Nzira yekugadzirira inoshanda zvakanyanyaChlorempenthrinUpfu husina kubikwa hwakakamurwa kuita matanho matatu akatevedzana:
Mumudziyo wekuita reaction wakashongedzwa ne condenser yekudzoreredza, kumutsa, kudonhedza, kudziyisa nekutonhodza, 200g ye dichloroethane uye 200g ye sodium acetylene zvakawedzerwa. Mushure mekumutsa nekutonhodza kusvika pa10.℃, 30g ye sodium hydroxide yakawedzerwa zvishoma nezvishoma muinenge awa imwe chete. Tembiricha yakabva yakwira kusvika pa50℃, uye 100g ye valenal yakadonhedzwa kwemaawa maviri. Mushure mekudonhedzwa, tembiricha yakaramba iripo kwemaawa gumi, uye reaction yapera. Wedzera 100g yemvura kuti iome, paradzanisa organic phase, geza neacid uye geza organic phase nemvura, iomese ne sodium sulfate, woinyungudutsa kuti uwane 120g ye acetylene amyl alcohol. Pokufashaira: 140-160℃, zviri mukati: 98%, goho: 94.8%.
(2)Nyungudutsa 62g yeacetylene amyl alcohol kubva padanho rekare mu460g yetoluene, wedzera 0.1g yetriethylamine sechinokonzeresa, kurunga woitonhodza kusvika pa5.℃, wobva waisa 116g ye all-trans DV inulyl chloride kwemaawa maviri. Kana yawedzerwa, chengeta pa 20℃Kwemaawa matanhatu uye mhinduro yacho yapera. Mvura yakagezwa kaviri, uye solvent yakadzorerwa nekubviswa kwemvura ye reaction kuti iwane mafuta asina kucheneswa echlorenyl pyrethroid. Mugove wemafuta asina kucheneswa waive magiramu 157, negoho re95%.
(3) Nyungudutsa 100g yeChlorempenthrin isina kucheneswa mu200g yeisopropanol, wedzera 0.1g yecatalyst triethylamine, woitonhodza kusvika pa5.℃, kurungai moita makristaro kwemaawa matanhatu, mobvisa centrifuge moburitsa zvinhu zvacho, mozoomesa upfu hwepakutanga kuti muwane upfu hwechlorenethrin mbishi hunoshanda zvakanyanya.
