DEET (Chingerezi: diethylmethylbenzamide), yomwe dzina lake ndi diethyltoluamide, ndi mankhwala ophera tizilombo tosiyanasiyana. Chemicalbook ili ndi mphamvu yophera tizilombo tosiyanasiyana toluma m'malo osiyanasiyana ndipo imatha kuphera tizilombo toluma. , midges, black flies, chiggers, deer flies, utitiri, udzudzu, horse flies, udzudzu, sand flies, udzudzu, stable flies ndi nkhupakupa.

katundu wa mankhwala

Madzi osakhala ndi utoto kapena amber. Ali ndi fungo lopepuka la citrus. Sasungunuka m'madzi, koma amatha kusakanikirana ndi ethanol, 2-propanol, propylene glycol ndi mafuta a thonje. Kuchuluka kwa meta-isomer m'zinthu zamafakitale ndi 85 mpaka 95%, d24 ndi 0.996 mpaka 0.998, ndipo kukhuthala pa 30°C ndi 13.3 centimita Chemicalbook poise. Mtengo wa LD50 wa pakamwa wa makoswe oyera aamuna ndi pafupifupi 2000mg/kg; kudyetsa makoswe ndi chakudya chokhala ndi 1% DEET kwa masiku 200 sikuli ndi zotsatirapo zoyipa; mankhwala osasungunuka amatha kukwiyitsa nembanemba ya mucous, koma amagwiritsa ntchito kuchuluka kwa DEET pankhope ndi pankhope panu tsiku lililonse. Pamanja, zimayambitsa kukwiya pang'ono kokha.

Cholinga:

Monga mankhwala ophera tizilombo, DEET ndiye chinthu chachikulu chophera tizilombo m'magulu osiyanasiyana ophera udzudzu olimba komanso amadzimadzi. Ili ndi zotsatira zapadera popewa udzudzu. Ma isomer onse atatu ali ndi mphamvu yophera udzudzu, ndipo meta-isomer ndiye wamphamvu kwambiri. Kukonzekera: 70%, 95% yamadzimadzi.
