Nhanganyaya

2,3-Diethyl-5-methylpyrazine is an organic compound, inozivikanwawo seDEET (N,N-diethyl-3-methylphenylethylamine).

 

Izvi zvinotevera zvimwe zvezvivakwa zve2,3-diethyl-5-methylpyrazine:

 

1. Chitarisiko: DEET imvura isina ruvara kune yakapenya yero.

2. Hwema: Iine spicy, organic hwema.

3. Solubility: DEET inonyungudika mudoro, ethers uye yakawanda organic solvents, asi ine yakaderera solubility mumvura.

 

Kushandiswa kukuru kwe2,3-diethyl-5-methylpyrazine sechinhu chinodzivirira zvirwere zvezvipembenene uye zvipembenene. Inoshanda kurwisana nekurumwa kwezvipembenene zvakasiyana-siyana zvakadai seumhutu, zvikwekwe, uye nhunzi, nezvimwewo. DEET inowanzoshandiswa pakugadzirwa kwezvinhu zvakadai sezvipembenene, zviputi zvehutu, zvipembenene uye zvipembenene zvinopisa zvipembenene.

 

Iyo nzira yekugadzirira 2,3-diethyl-5-methylpyrazine inowanzoitwa necatalytic kuwedzera reaction ye benzylamine uye chloroacetic acid, pamberi pealkali, kugadzira N-benzyl-N-methylacetamide, uyezve kuburikidza nekupererwa kwemvura kuita kuti uwane.

Ruzivo Rwekuchengetedza: 2,3-Diethyl-5-methylpyrazine inoonekwa seyakachengeteka pasi pemamiriro ekushandiswa. Kuchenjerera kunodiwa kana uchishandisa vamwe vanhu, sevana, vakadzi vane pamuviri uye vanoyamwisa, uye vanhu vane allergies kuDEET. Kugara kwenguva refu kuratidzwa kuDEET kunogona kukonzera mhedzisiro senge ganda allergies uye kutsamwa kweziso, saka geza maoko ako nenzvimbo dzakafumurwa dzeganda mushure mekushandisa. Kana chero kusagadzikana kana kukanganisa kwakashata kuchiitika, rega kushandisa nekukurumidza uye bvunza chiremba.
