Cov Khoom Siv Dav Dav ntawm Cawv
Cawv yog ib yam kua tsis muaj xim, pob tshab, yaj tau yooj yim, yoo hluav taws, thiab tsis ua hluav taws xob. Nws muaj ntxhiab zoo li cawv, saj ntsim thiab qab zib me ntsis tom qab. Nws lub npe scientific yog ethanol, nrog rau cov mis molecular C₂H₅OH. Nws hu ua "cawv" vim nws cov qauv molecular muaj ib pawg hydroxyl (-OH).
Qhov chaw khov: ~ -114 ° C
Kub taw tes: 78.3°C
Nws tuaj yeem sib tov nrog dej, ether, chloroform, thiab lwm yam organic solvents hauv txhua qhov piv txwv thiab yog hygroscopic, tsim cov azeotropic sib tov nrog dej.
Cov pa roj ethanol tuaj yeem ua rau muaj kev sib xyaw ua ke nrog huab cua, nrog rau qhov txwv kev tawg hauv huab cua.
Thaum muaj qhov concentration ntawm 70% (v/v), cawv muaj cov nyhuv tua kab mob zoo heev thiab kuj siv tau ua cov tshuaj preservative thiab cov kuab tshuaj.
Hauv lub xeev supercritical (243°C, 60 kg/cm²), ethanol ua rau pom tias nws muaj zog heev, ua rau nws rho tau cov kua dej supercritical tawm tau.
Vim nws qhov chaw khov qis, cov cawv daws teeb meem ntawm qee qhov concentration tuaj yeem siv ua antifreeze thiab refrigerants.
Ethanol tuaj yeem hloov roj av ua roj, ua rau nws yog lub zog rov ua dua tshiab.
