TETREDM siv tau ua cov kuab tshuaj zoo heev rau alkaline hlau hydride thiab siv rau hauv kev sib xyaw ua ke ntawm alkyl lossis rov ua dua cov tshuaj lom neeg. Nrog Louise Alkalinity, nws tuaj yeem nqus cov roj acid kom ntxuav cov roj synthetic, roj ntuj thiab acetylene. (CEEB TOOM: cov khoom no tsis tuaj yeem raug rau sab nraud ntev, txwv tsis pub nws tuaj yeem tsim cov peroxide.)
