Isopropyl cawv, tseem hu ua isopropanol lossis 2-propanol, yog cov organic hnyav nrog cov mis molecular ntawm C3H8O.Nws cov khoom siv tshuaj lom neeg thiab cov yam ntxwv ntawm lub cev yeej ib txwm yog cov ntsiab lus ntawm kev txaus siab ntawm chemists thiab laymen xwm yeem.Ib qho lus nug tshwj xeeb tshaj yog seb puas yog isopropyl cawv yog soluble hauv dej.Txhawm rau kom nkag siab lo lus nug no, peb yuav tsum nkag siab txog thaj chaw ntawm chemistry thiab tshawb nrhiav kev sib cuam tshuam ntawm ob lub molecules.

Lub solubility ntawm ib yam khoom nyob rau hauv ib tug muab solvent yog txiav txim los ntawm kev sib cuam tshuam ntawm cov kuab tshuaj thiab hnyav molecules.Nyob rau hauv cov ntaub ntawv ntawm isopropyl cawv thiab dej, cov kev sib cuam tshuam yog feem ntau hydrogen bonding thiab van der Waals rog.Isopropyl cawv muaj ib pawg hydroxyl (-OH) uas tuaj yeem tsim hydrogen bonds nrog dej molecules, tab sis nws cov hydrocarbon tail repels dej.Tag nrho cov solubility ntawm isopropyl cawv hauv dej yog qhov sib npaug ntawm ob lub zog.

Interestingly, solubility ntawm isopropyl cawv hauv dej nyob ntawm qhov kub thiab txias.Nyob rau hauv chav tsev kub thiab hauv qab no, isopropyl cawv yog me ntsis soluble nyob rau hauv dej, nrog ib tug solubility ntawm li 20% los ntawm ntim ntawm 20 ° C.Raws li qhov kub nce, lub solubility txo.Thaum qhov kub thiab txias tsis tshua muaj, kev sib cais theem yuav tshwm sim, ua rau ob txheej sib txawv - ib qho nplua nuj ntawm isopropyl cawv thiab lwm yam dej nplua nuj.

Lub xub ntiag ntawm lwm cov tebchaw los yog surfactants tuaj yeem cuam tshuam rau solubility ntawm isopropyl cawv hauv dej.Piv txwv li, surfactants uas muaj kev sib raug zoo rau isopropyl cawv lossis dej tuaj yeem hloov kho lawv cov solubility.Cov cuab yeej no pom cov ntawv thov hauv ntau yam xws li tshuaj pleev ib ce, tshuaj, thiab agrochemicals, qhov twg surfactants feem ntau siv los txhim kho cov solubility ntawm cov khoom xyaw nquag.

Hauv kev xaus, solubility ntawm isopropyl cawv hauv dej yog qhov tshwm sim nyuaj uas cuam tshuam nrog kev sib npaug ntawm hydrogen bonding thiab van der Waals rog.Thaum nws yog me ntsis soluble ntawm chav tsev kub thiab hauv qab no, yam xws li kub, concentration, thiab muaj lwm cov tebchaw tuaj yeem cuam tshuam rau nws cov solubility.Kev nkag siab zoo ntawm cov kev sib cuam tshuam thiab cov xwm txheej no yog qhov tseem ceeb rau kev siv cov isopropyl cawv hauv ntau daim ntawv thov.
