Solubility Ethyl cellulose ee ethanol

Ethyl cellulose waa polymer synthetic oo caadi ahaan loo isticmaalo warshado kala duwan, oo ay ku jiraan daawooyinka, cuntada, iyo daryeelka shakhsi ahaaneed. Mid ka mid ah sifooyinka muhiimka ah ee ethyl cellulose waa milmaheeda kala duwan, taas oo muhiim u ah codsigeeda kala duwan. Ethanol waa mid ka mid ah dareerayaasha loo isticmaali karo in lagu milo ethyl cellulose.

Solubility of cellulose ethyl ee ethanol waxay ku xiran tahay arrimo kala duwan sida heerka ethylation, miisaanka kelli ee polymerka, iyo heerkulka dareeraha. Guud ahaan, ethyl cellulose oo leh heerar sare oo ethylation ah ayaa aad ugu milmay ethanol marka la barbar dhigo kuwa leh heerka hoose ee ethylation. Miisaanka molecular ee polymerka ayaa sidoo kale door ka ciyaara, sababtoo ah miisaanka molecular ee sarreeya ayaa laga yaabaa inay u baahdaan fiirsashada sare ee ethanol ama waqti dheer si ay u milaan.

Heerkulka dareeraha ayaa sidoo kale saameeya milanka ethyl cellulose ee ethanol. Heerkulka sare wuxuu kordhin karaa milanka polymerka sababtoo ah kororka tamarta kinetic ee molecules dareeraha, taas oo gacan ka geysan karta in la jebiyo silsiladaha polymer-ka oo fududeeya habka kala dirida. Si kastaba ha noqotee, heerkulku waa inuusan dhaafin xad go'an sababtoo ah waxay keeni kartaa polymer-ka inuu hoos u dhaco ama lumiyo sharaftiisa qaabdhismeed.

Guud ahaan, ethyl cellulose waxaa loo arkaa inuu aad ugu milmay ethanol marka la barbar dhigo dareerayaasha kale ee caadiga ah sida biyaha, methanol, iyo acetone. Ethanol waa dareere dabaylaha ah, iyo polarity-kiisu wuxuu kaa caawin karaa inuu burburiyo curaarta hydrogen ee u dhexeeya silsiladaha polymer, taas oo u oggolaanaysa polymerku inuu milmo.
