Puas yog ethyl cawv tib yam li isopropyl cawv?
Ethyl cawv (ethanol) thiab isopropyl cawv (isopropanol) tsis zoo ib yam; lawv yog cov tshuaj sib xyaws sib txawv.
Ethyl cawv, tseem hu ua ethanol, yog qhov zoo tshaj plaws - paub cawv. Nws yog hom cawv uas cov neeg haus cawv haus cawv. Cov qauv tshuaj ntawm ethanol yog C2H5OH. Ethanol yog ib txwm tsim los ntawm cov poov xab thaum lawv ferment qab zib. Raws li kev haus dej haus, nws tau siv kho mob ua tshuaj tua kab mob thiab tshuaj tua kab mob. Nws yog ib qho kev sib ntxiv rau cov roj cav. Ntau tshaj 98 feem pua ntawm cov roj av hauv Tebchaws Meskas muaj ethyl cawv.
Isopropyl cawv CAS 67-63-0, feem ntau hu ua IPA lossis Propan-2-ol , yog cov nplaim hluav taws kub hnyiab, ntshiab, tsis muaj xim ua kua nrog cov ntxhiab tsw qab ntxiag me ntsis. Nws muaj lub cev, tshuaj lom neeg thiab kuab tshuaj zoo ib yam li cov ethyl cawv, ua rau nws tag nrho miscible nrog dej thiab soluble hauv feem ntau cov kuab tshuaj organic.
