Ndeipi nzira yekugadzirira ye-high-effect Chlorempenthrin poda yakasvibirira

Chlorempenthrinrudzi rutsva rwepyrethroid insecticide ine hunyanzvi hwepamusoro uye yakaderera chepfu, iyo ine mhedzisiro yakanaka kune umhutu, nhunzi uye mapete.Iyo inoratidzira yakakwira vapor pressure, yakanaka volatility uye yakasimba kuuraya simba. Inogona kudonhedza tupukanana nekukasira, kunyanya kana ikapfapfaidzwa kana kufifitwa, kugogodza kunonyanya kukosha.

Kugadzirira

Nzira yekugadzirira yepamusoro-soroChlorempenthrinpoda mbishi yakakamurwa kuita nhanho nhatu mukutevedzana:

Mumudziyo wekuita wakashongedzerwa ne condenser ye reflux, kubvongodza, kudonha kuwedzera, kupisa uye kutonhora, 200g ye dichloroethane uye 200g ye sodium acetylene yakawedzerwa. Mushure mekusimudzira uye kutonhora kusvika ku10℃, 30g ye sodium hydroxide yakawedzerwa zvishoma nezvishoma muinenge 1 awa. Zvadaro tembiricha yakawedzera kusvika 50℃, uye 100g yevalenal yakadonhedzwa mukati kwemaawa maviri. Mushure mekudonha kuwedzera, tembiricha yakachengetwa kwemaawa gumi, uye kuita kwakapedzwa. Wedzera 100g yemvura yehydrolysis, patsanura chikamu che organic, acid wash uye mvura geza iyo organic phase, iome ne sodium sulfate, uye nyungudutsa kuti uwane 120g yeacetylene amyl doro. Kubika nzvimbo: 140-160℃, zvirimo: 98%, goho: 94.8%.

(2)Dissolve 62g yeacetylene amyl doro kubva padanho rekare mu460g yetoluene, wedzera 0.1g ye triethylamine sechinhu chinokonzeresa, kurunga uye kutonhorera kusvika pa5.℃, wobva wadonhedza 116g ye all-trans DV inulyl chloride kwemaawa maviri. Mushure mekuwedzera kwapera, chengeta pa20℃kwemaawa matanhatu uye mhinduro yapera. Mvura yakashambidzwa kaviri, uye munyungurutsi wakadzoserwa nekunyungudika kwemvura inoita kuti iwane mafuta akashata echlorenyl pyrethroid. Goho remafuta asina kuoreswa raive 157 gramu, negoho re95%.

(3) Dissolve 100g yecrude Chlorempenthrin mu 200g ye isopropanol, wedzera 0.1g ye catalyst triethylamine, inotonhorera kusvika ku5℃, simbisa uye crystallize kwemaawa matanhatu, centrifuge uye kubudisa zvinhu, wobva waomesa poda yepakutanga kuti uwane yakakwirira-inoshanda chlorenethrin poda yakasvibirira.
