ʻO ka diethylmethylbenzamide kahi mea hoʻomakeʻe ākea ākea e pale aku i nā ʻano pepeke nahu i nā ʻano like ʻole. Hiki iā ia ke pale aku i nā nalo spiny, midges, nalo ʻeleʻele, chiggers, lele dia, ʻautuʻu, nahu, nalo lio, Namu, nalo one, nalo, nalo paʻa a me nā ʻaʻa.

Na Waiwai Kemika

ʻAʻole waihoʻoluʻu i ka wai amber. He ʻala citrus māmā. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hui pū me ka ethanol, 2-propanol, propylene glycol a me ka ʻaila pulupulu. ʻO ka maʻiʻo meta-isomer o nā huahana ʻoihana ʻo 85 a 95%, d24 ʻo 0.996 a 0.998, a ʻo ka viscosity ma 30 ° C he 13.Chemicalbook 3 centipoise. ʻO ka waiwai LD50 waha waha o nā ʻiole keʻokeʻo kāne ma kahi o 2000mg/kg; ʻO ka hānai ʻana i nā ʻiole me ka hānai i loaʻa ka 1% DEET no 200 mau lā ʻaʻohe hopena ʻino; Hiki i ka hui i hoʻokaʻawale ʻole ke hoʻonāukiuki i nā membrane mucous, akā e hoʻohana i ka neʻe repellent o DEET ma kou alo a me kou alo i kēlā me kēia lā Ma nā lima, e hoʻoulu wale i ka ʻeha.

Ke kumu:

Ma ke ʻano he mea hoʻomake pepeke, ʻo DEET ka mea hoʻoheheʻe nui i loko o nā pūʻulu namu paʻa a me ka wai. Loaʻa iā ia nā hopena kūikawā i ka pale ʻana i nā makika. Loaʻa i nā isomer ʻekolu ka hopena o ka namu, a ʻo ka meta-isomer ka mea ikaika loa. Hoʻomākaukau: 70%, 95% wai.

Hana hana:

Loaʻa mai ka hopena o ka m-toluoyl chloride a me diethylamine. Loaʻa nā huahana ʻenehana i ka 5% -15% isomers.
