Ethanol, feem ntau hu ua cawv, yog ib qho organic compound nrog cov qauv mis CH₃CH₂OH (lossis C₂H₅OH) thiab cov qauv molecular C₂H₆O. Nws yog cov cawv monohydric feem ntau.
Thaum sov thiab siab, ethanol yog cov kua uas yoo hluav taws, yoo hloov pauv, tsis muaj xim pob tshab thiab tsis muaj tshuaj lom; cov kua ntshiab tsis haus tau ncaj qha. Nws muaj ib qho tsw qab tshwj xeeb nrog me ntsis pungency, me ntsis qab zib, thiab khaus, pungent. Nws yog flammable, thiab nws cov pa tuaj yeem ua rau muaj kev sib xyaw nrog huab cua.

Nrog 20 xyoo ntawm kev paub txog kev xa tawm cov tshuaj lom neeg lag luam, Shandong Pulisi Chemical Co., Ltd. tau tsim nws tus kheej ua tus neeg muab khoom zoo thoob ntiaj teb suav nrog calcium chloride, ethanol, formic acid, sodium formate, thiab sodium hydrosulfide. Peb txoj kev cog lus tsis tu ncua rau qhov zoo sib xws, cov khoom xa tuaj txhim khu kev qha, thiab cov kev daws teeb meem rau cov neeg siv khoom tau ua rau peb pabcuam cov neeg koom tes thoob plaws 30 lub tebchaws, taug kev hauv kev lag luam thoob ntiaj teb nrog kev txawj ntse. Ua tus thawj coj tsim tshuaj lom neeg nyob hauv Shandong, Suav teb, peb txuas ntxiv siv cov chaw tsim khoom siab heev, kev tswj hwm zoo, thiab kev xa khoom zoo kom xa tus nqi thiab xyuas kom meej tias xa khoom raws sijhawm rau txhua tus neeg siv khoom.

Nyem qhov no kom tau txais tus nqi luv nqi.
