DEET (Ingiriis diethylmethylbenzamide), oo magaceedu kiimikaad yahay diethyltoluamide, waa cayayaan-ka-celiya ballaaran. Kiimikada buuggu waxay saameyn xun ku leedahay cayayaan qaniinyo kala duwan oo degaanno kala duwan ku nool waxayna iska celin kartaa duqsigu. Midges, duqsi madow, chiggers, duqsigu deerada, boodada, kaneecada, dukhsiga fardaha, kaneecada, ciida duqsiga, xabagta, duqsi xasiloon iyo shilin

sifooyinka kiimikada

Midab la'aan ilaa dareere cambar ah. Waxay leedahay udgoon liinta khafiif ah. Dhab ahaantii aan lagu milmi karin biyaha, laakiin waxaa lagu khaldi karaa ethanol, 2-propanol, propylene glycol iyo saliida suufka. Maaddada-meta-isomer-ka ee alaabta warshaduhu waa 85 ilaa 95%, d24 waa 0.996 ilaa 0.998, viscosity at 30°C waa 13.3 sentimitir litirka buuga Kiimikada. Qiimaha ba'an ee afka LD50 ee jiirka cad ee ragga waa qiyaastii 2000mg/kg; quudinta jiirka oo leh quudin ka kooban 1% DEET 200 maalmood ma laha saameyn xun; Isku-xidhka aan la milmin waxay ka xanaajin kartaa xuubka xabkaha, laakiin isticmaal DEET fiirsashada wajigaaga iyo wejigaaga maalin kasta Gacmaha, waxay sababtaa xanaaq fudud oo keliya.

Ujeedo:

Ka-hortagga cayayaanka, DEET waa maadada ugu weyn ee ka hortagga kaneecada ee kala duwan. Waxay saameyn gaar ah ku leedahay ka hortagga kaneecada. Dhammaan seddexda isomers waxay saameyn xun ku leeyihiin kaneecada, iyo meta-isomer-ka ayaa ah kan ugu xooggan. Diyaarinta: 70%, 95% dareere.
