Ethyl cellulose solubility ee acetone

Ethyl cellulose waa polymer si ballaaran loo isticmaalo warshado kala duwan, oo ay ku jiraan daawooyinka, cuntada, iyo daryeelka shakhsi ahaaneed. Waxaa lagu yaqaanaa sifooyinkeeda filim-samaynta aadka u wanaagsan, ku habboonaanta sare ee qalabka kale, iyo caabbinta wanaagsan ee kiimikooyinka iyo arrimaha deegaanka. Mid ka mid ah sifooyinka muhiimka ah ee ethyl cellulose waa milmayntiisa, taas oo kala duwanaan karta iyadoo ku xiran dareeraha la isticmaalo.

Acetone waa dareere caadi ah oo inta badan loo isticmaalo soo saarista filimada ethyl cellulose iyo dahaarka. Ethyl cellulose waxay qayb ahaan ku milmi kartaa acetone, taasoo la micno ah inay milmi karto ilaa xad laakiin laga yaabo inaanay si buuxda u milmin. Heerka milanka ee cellulose ethyl ee acetone waxay kuxirantahay arrimo kala duwan sida miisaanka kelli, heerka ethoxylation, iyo diirada polymer.

Guud ahaan, miisaanka unugyadu sareeyo ee ethyl cellulose waxa ay u egtahay in ay ku milmi yartahay acetone marka la barbar dhigo miisaanka molecular hoose ee ethyl cellulose. Tani waa sababta oo ah polymers-ka miisaanka molecular ee sarreeya ayaa leh heer sare oo polymerization ah, taas oo keentay qaab dhismeed aad u adag oo adag oo aad u adkaysta xallinta. Sidoo kale, ethyl cellulose oo leh heer sare oo ethoxylation ah waxay u egtahay inay ku yar tahay milanka acetone sababtoo ah kororka hydrophobicity ee polymer.

Solubility of cellulose ethyl ee acetone sidoo kale waxaa saameyn kara xoojinta polymer ee dareeraha. Heerarka hoose, ethyl cellulose waxay u badan tahay inay ku milmaan acetone, halka xaddi badan, milmayntu ay yarayn karto. Tani waxay sabab u tahay xaqiiqda ah in heerarka sare, molecules ethyl cellulose ay u badan tahay inay is dhexgalaan midba midka kale, sameynta shabakad silsilado polymer ah oo aan ku milmin dareeraha.

Solubility of ethyl cellulose ee acetone waxaa lagu wanaajin karaa iyada oo lagu daro dareerayaasha kale ama balaastikada. Tusaale ahaan, ku darida ethanol ama isopropanol ee acetone waxay kordhin kartaa milanka ethyl cellulose iyada oo la carqaladeynayo isdhexgalka intermolecular ee ka dhexeeya silsiladaha polymer. Sidoo kale, ku darida balaastikada sida triethyl citrate ama dibutyl phthalate waxay kordhin kartaa milanka ethyl cellulose iyadoo la yareynayo xoogagga intermolecular ee u dhexeeya silsiladaha polymer.

Marka la soo koobo, ethyl cellulose waxay qayb ahaan ku milmi kartaa acetone, milmadeeduna way kala duwanaan kartaa iyadoo ku xidhan arrimo kala duwan sida miisaanka kelli, heerka ethoxylation, iyo xoojinta polymerka. Solubility of cellulose ethyl ee acetone waxaa lagu wanaajin karaa iyada oo lagu daro dareerayaasha kale ama balaastikada, taas oo ka dhigaysa polymer ah oo isku dhafan oo loo isticmaalo codsiyada kala duwan.
