Ethyl cellulose solubility na ethanol

Ethyl cellulose bụ polymer sịntetik nke a na-ejikarị na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, na nlekọta onwe onye. Otu n'ime ihe ndị bụ isi nke ethyl cellulose bụ solubility ya na ihe mgbaze dị iche iche, nke dị mkpa maka ngwa dị iche iche. Ethanol bụ otu n'ime ihe mgbaze enwere ike iji gbazee ethyl cellulose.

Solubility nke ethyl cellulose na ethanol na-adabere n'ihe dị iche iche dị ka ogo ethylation, arọ molecular nke polymer, na okpomọkụ nke ihe mgbaze. N'ozuzu, ethyl cellulose nke nwere ọkwa dị elu nke ethylation na-esiwanye ike na ethanol ma e jiri ya tụnyere ndị nwere obere ọkwa ethylation. Ibu arọ molekụla nke polymer na-arụkwa ọrụ, ebe ọ bụ na polymer arọ molekụla dị elu nwere ike ịchọ ọkwa dị elu nke ethanol ma ọ bụ ogologo oge iji gbazee.

Ọnọdụ okpomọkụ nke ihe mgbaze na-emetụtakwa solubility nke ethyl cellulose na ethanol. Okpomọkụ dị elu nwere ike ịbawanye solubility nke polymer n'ihi ụba ike nke kinetic nke mkpụrụ ndụ ihe mgbaze, nke nwere ike inye aka ịkụda ụdọ polymer ma kwado usoro mgbasa. Otú ọ dị, okpomọkụ ekwesịghị ịfefe ụfọdụ oke n'ihi na ọ nwere ike ime ka polima weda ma ọ bụ tụfuo iguzosi ike n'ezi ihe ya.

N'ozuzu, a na-ewere ethyl cellulose dị ka ihe soluble na ethanol ma e jiri ya tụnyere ihe mgbaze ndị ọzọ dị ka mmiri, methanol, na acetone. Ethanol bụ ihe mgbaze pola, na polarity ya nwere ike inye aka imebi njikọ hydrogen n'etiti ụdọ polymer, na-ekwe ka polymer gbazee.
