DEET (Chingerezi diethylmethylbenzamide), yemwe dzina lake lamankhwala ndi diethyltoluamide, ndi mankhwala othamangitsa tizilombo. Chemicalbook imakhala ndi mphamvu yothamangitsa tizilombo tosiyanasiyana toluma m'malo osiyanasiyana ndipo imatha kuthamangitsa ntchentche zoluma. , ntchentche zakuda, ntchentche zakuda, ntchentche, utitiri, udzudzu, ntchentche za akavalo, udzudzu, ntchentche za mchenga, udzudzu, ntchentche zokhazikika komanso nkhupakupa

mankhwala katundu

Madzi opanda mtundu mpaka amber. Lili ndi fungo lopepuka la citrus. Pafupifupi osasungunuka m'madzi, koma osakanikirana ndi ethanol, 2-propanol, propylene glycol ndi mafuta a cottonseed. Zomwe zili m'mafakitale a meta-isomer ndi 85 mpaka 95%, d24 ndi 0.996 mpaka 0.998, ndipo kukhuthala kwa 30 ° C ndi 13.3 centimita Chemicalbook poise. The pachimake pakamwa LD50 mtengo wamphongo woyera makoswe ndi za 2000mg/kg; kudyetsa makoswe ndi chakudya chokhala ndi 1% DEET kwa masiku 200 alibe zotsatira zoyipa; chigawo chosasunthika chimatha kukwiyitsa mucous nembanemba, koma gwiritsani ntchito mankhwala osokoneza bongo a DEET pankhope ndi kumaso tsiku lililonse Pamikono, zimayambitsa kupsa mtima pang'ono.

Cholinga:

Monga chothamangitsira tizilombo, DEET ndiye chinthu chachikulu chothamangitsira pamitundu yosiyanasiyana yolimba komanso yamadzimadzi yothamangitsa udzudzu. Ili ndi zotsatira zapadera popewa udzudzu. Ma isomer onse atatu ali ndi mphamvu yothamangitsa udzudzu, ndipo meta-isomer ndi yamphamvu kwambiri. Kukonzekera: 70%, 95% madzi.
