Isobutyl cawv (CAS 78-83-1)yog ib qho xim tsis muaj xim thiab pob tshab organic nrog cov yam ntxwv ntawm cov ntxhiab tsw ntxhiab. Nws yog cov kua dej ntawm chav tsev kub nrog qhov kub ntawm qhov kub ntawm 108℃thiab yog miscible nrog dej, ethanol, ether, thiab ntau lwm cov kuab tshuaj. Raws li ib qho tseem ceeb tshuaj raw khoom, isobutyl cawv muaj ntau yam kev siv hauv kev tsim khoom.
Chemical Structure thiab Properties of Isobutyl Cawv
Lub npe tshuaj ntawm isobutyl cawv yog 2-methyl-1-propanol, nrog rau cov mis mos molecular C₄H₁₀O. Nws cov yam ntxwv tshwj xeeb yog tias pawg hydroxyl (-OH) txuas nrog cov pa roj carbon atom uas muaj methyl sab saw, uas muab cov tshuaj sib txawv me ntsis ntawm n-butanol. Piv txwv li, isobutyl cawv muaj qhov kub qis me ntsis thiab siab dua volatility dua n-butanol. Nws kuj muaj cov solubility zoo thiab tuaj yeem sib tov zoo nrog ntau cov kuab tshuaj organic, ua kom muaj ntau yam hauv kev siv hauv kev lag luam.
Isobutyl cawv hlawv yooj yim hauv huab cua, ua rau carbon dioxide thiab dej vapor thaum combustion. Vim nws cov nplaim taws, nws yuav tsum tau muab khaws cia thiab siv kom deb ntawm cov nplaim taws qhib thiab siab - qhov kub thiab txias. Nws tuaj yeem ua rau tawv nqaij thiab qhov muag, yog li cov hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav thaum tuav.
