Ethyl cellulose solubility a cikin ethanol

Ethyl cellulose solubility a cikin ethanol

Ethyl cellulose shine polymer roba wanda ake amfani dashi a masana'antu daban-daban, ciki har da magunguna, abinci, da kulawa na sirri. Ɗaya daga cikin mahimman kaddarorin ethyl cellulose shine mai narkewa a cikin kaushi daban-daban, wanda ke da mahimmanci ga aikace-aikacen sa daban-daban. Ethanol yana daya daga cikin abubuwan da za a iya amfani dashi don narkar da ethyl cellulose.

Solubility na ethyl cellulose a cikin ethanol ya dogara da abubuwa daban-daban kamar matakin ethylation, nauyin kwayoyin halitta na polymer, da zafin jiki na sauran ƙarfi. Gabaɗaya, ethyl cellulose tare da digiri mafi girma na ethylation ya fi soluble a cikin ethanol idan aka kwatanta da waɗanda ke da ƙananan digiri na ethylation. Nauyin kwayoyin halitta na polymer shima yana taka rawa, saboda mafi girman nau'in polymers na iya buƙatar haɓakar ethanol mafi girma ko kuma tsawon lokaci don narkewa.

Hakanan zafin jiki na sauran ƙarfi yana rinjayar solubility na ethyl cellulose a cikin ethanol. Yanayin zafi mafi girma na iya ƙara yawan solubility na polymer saboda ƙãra makamashin motsi na ƙwayoyin ƙarfi, wanda zai iya taimakawa wajen karya sarƙoƙin polymer da sauƙaƙe tsarin rushewa. Koyaya, zafin jiki bai kamata ya wuce ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai ba saboda yana iya haifar da polymer ya ragu ko ya rasa amincin tsarin sa.

Gabaɗaya, ana ɗaukar ethyl cellulose don zama mai narkewa a cikin ethanol idan aka kwatanta da sauran abubuwan da aka saba amfani da su kamar ruwa, methanol, da acetone. Ethanol wani kaushi ne na iyakacin duniya, kuma polarity nasa zai iya taimakawa wajen karya haɗin gwiwar hydrogen tsakanin sarƙoƙin polymer, yana barin polymer ya narke.
