Furanone Acetate (CAS#4166-20-5)

Mawu Oyamba

4-Acetoxy-2,5-dimethyl-3-furanone (yomwe imadziwikanso kuti DEET) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri poletsa udzudzu. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

Ubwino:

- Maonekedwe: Madzi opanda mtundu kapena achikasu

- Kusungunuka: Kusungunuka mu mowa, ethers ndi ketones, osasungunuka m'madzi

Gwiritsani ntchito:

- DEET imagwiritsidwa ntchito makamaka ngati mankhwala oletsa udzudzu, omwe amatha kuthamangitsa udzudzu, nkhupakupa ndi tizilombo tina.

- DEET imagwiritsidwanso ntchito popewa kulumidwa ndi tizilombo tina, monga nsabwe, utitiri, ndi nkhupakupa.

Njira:

4-Acetoxy-2,5-dimethyl-3-furanone ikhoza kukonzedwa ndi izi:

1. 2,5-Dimethyl-3-furanone imakhudzidwa ndi acetic anhydride kupanga 4-acetoxy-2,5-dimethyl-3-furanone.

Zambiri Zachitetezo:

- Pewani kukhudza maso, mkamwa, ndi mabala otseguka.

- DEET imakwiyitsa ndipo kukhudzana kwanthawi yayitali ndi khungu kungayambitse kuyabwa, ziwengo, kapena khungu louma.

- Pewani kukhudzana mwachindunji ndi mapulasitiki, ulusi wopangidwa ndi anthu, ndi zina, zomwe zingayambitse dzimbiri.

- Manja ndi khungu lowonekera ziyenera kutsukidwa bwino mukamagwiritsa ntchito. Ngati kusapeza kumachitika, siyani kugwiritsa ntchito nthawi yomweyo ndipo funsani dokotala.
