I-diethylmethylbenzamide sisigxobhozo esibanzi sezinambuzane esigxotha iintlobo ngeentlobo zezinambuzane ezilumayo kwiindawo ezahlukeneyo. Iyakwazi ukugxotha iimpukane ze-spiny, i-midges, i-black fly, i-chiggers, i-deer flyes, i-fleas, i-gnat, i-horse fly, i-Mosquitoes, iindiza zesanti, iimbuzane, iimpukane ezizinzileyo kunye namakhalane.

Iipropati zeMichiza

Ulwelo olungenambala ukuya kwi-amber. Inevumba elikhanyayo lesitrasi. Ngokucacileyo ayinyibiliki emanzini, kodwa ixutywe ne-ethanol, i-2-propanol, i-propylene glycol kunye neoli ye-cottonseed. Umxholo we-meta-isomer weemveliso zoshishino yi-85 ukuya kwi-95%, i-d24 yi-0.996 ukuya kwi-0.998, kunye ne-viscosity kwi-30 ° C yi-13.Chemicalbook 3 centipoise. Ixabiso elibukhali lomlomo we-LD50 yeegundane ezimhlophe zamadoda malunga ne-2000mg / kg; ukondla iigundane ngokutya okuqukethe i-1% DEET iintsuku ezingama-200 akukho miphumo emibi; i-compound engaxutywanga inokucaphukisa i-mucous membranes, kodwa sebenzisa i-repellent concentration ye-DEET ebusweni bakho kunye nobuso yonke imihla Kwiingalo, kubangela ukucaphuka okuncinci kuphela.

Injongo:

Njengesigxothi sezinambuzane, i-DEET sesona sithako sigxothayo kwiinkqubo ezahlukeneyo zokugxotha iingcongconi eziqinileyo nezilulwelo. Ineziphumo ezikhethekileyo ekuthinteleni iingcongconi. Zontathu i-isomers zinefuthe lokugxotha kwiingcongconi, kwaye i-meta-isomer yeyona inamandla. Ukulungiselela: 70%, 95% ulwelo.

Indlela yokuvelisa:

Ifunyenwe kwi-reaction ye-m-toluoyl chloride kunye ne-diethylamine. Iimveliso zamashishini ziqulethe i-5% -15% isomers.
