Zeziphi iindlela zokunyibilikisa i-ether esesele?

Ukuchithwa kwee-Selessese e Seleulose kunokuba linyathelo elibalulekileyo kumashishini ahlukeneyo njengamayeza, ukutya, izilumkiso, nolwakhiwo.I-seluplosezisetyenziswa kakhulu ngenxa yepropathi yabo efana nokutyibilika, ukubopha, ukwenza ifilimu, kunye nokuzinzisa. Nangona kunjalo, ukungoneliseki kwabo kwiindlela ezininzi eziqhelekileyo kunokongeza imiceli mngeni. Iindlela ezininzi ziye zaphuhliswa ukuze zinyibilike ii-selupely.

Izinyibilikisi ze-organic:

I-alcohols: I-Isphals ephantsi kakhulu e-Ethanol, i-Methanol, kunye ne-Iyopropanol inokunyibilikisa ii-selsulose ukuya kuthi ga. Nangona kunjalo, basenokungalungelanga zonke iintlobo zeselpulose
Umxube we-Ether-utywala: Imixube ye-Dietthyl Ether kunye ne-ethanol okanye i-methanol ihlala isetyenziselwa ukunyibilikisa ii-seluples. Ezi zinyibilikisi zibonelela ngokuqina okufanelekileyo kwaye zihlala zisetyenziswa kwizicwangciso zelebhu.
I-ketones: ezinye iiKetones ezinje nge-acetone ne-methyl yeyyl ketone (mek) inokunyibilikisa iintlobo ezithile zeselsese. I-Acetone, ngakumbi, isetyenziswa ngokubanzi ngenxa yeendleko zayo eziphantsi kunye nokusebenza kakuhle.
Esters: Ii-Esters ezinje nge-ethyl acetate kunye ne-butyl acetate inokuchithakala e-Selese. Nangona kunjalo, banokufuna ukufudumeza ukuze kufezekiswe ngokupheleleyo.

Izisombululo eziMvume:

Isisombululo se-Alkaline: I-Selethule inyibilikiswe kwizisombululo zeAlkaline ezinje ngeSodium hydroxide (i-nah) okanye potassium hydroxide (Koh). Ezi zisombululo ze-hydrolyze i-seluplose ifomu ukuze ifomu ye-alkali yentsimbi, enyibilikayo.
Izisombululo ze-Ammonia: I-Ammonia (i-Ammonia (NH3) inokusetyenziswa ukunyibilikisa ii-selupeses ngokutsala iityuwa ze-ammoium.
I-Hydroxalkyl Irea Izisombululo: I-HydroX'sKylkyl Irea Izisombululo, ezinjenge-hydroxyythl you okanye i-hydroxypropy youre, ingayinyibilikisa i-Selease, ngakumbi abo banamanqanaba asezantsi.

Ulwelo lwe-Ionic:

Ulwelo lwe-Ionic luluhlu lwezinto eziphilayo ezilulwelo lwamaqondo obushushu aphantsi, zihlala zingaphantsi kwe-100 ° C. Ezinye izinto ezithile ze-Ionic zifunyenwe zinyibilikisile iiselwase Banika izibonelelo ezifana nokuzinza okusezantsi, uzinzo oluphakameyo, kunye nokuphinda zisebenzise kwakhona.

Iinkqubo zeSolta ezixubileyo:

Ukudibanisa izinyibilikisi ezahlukeneyo kunokubangela ukubethwa kwe-seluplose ye-selese. Umzekelo, umxube wamanzi onesinyibilikisi njenge-Dimthyl SulfoXide (DMSO) okanye i-DMSO) okanye i-N-Methyl-2-Pmetlidone (NMP) inokuphucula iipropathi zokuchitha.
Ingqondo ye-hansen ye-Hissen Solubing ihlala isebenza ngendlela esebenzayo yokuyila inyibilikisi yokuphelisa ii-selsulose Tables ngokujonga iiparamitha zokucoca izinyibilikisi kunye nokusebenzisana kwazo.

Iindlela zomzimba:

Ukucheba koomatshini: Ukudityaniswa kwehetari ephezulu okanye ukunuka kunokunceda ekusasazeni ii-selsulose kuthuntu kwizinyithi kunye nokuphucula ii-kinetics ze-kinetics.
Ulawulo lobushushu: Amaqondo obushushu aphakamileyo anokuthi aphucule i-solubise ye-seluplose eeke iinyibilikisi, kodwa kufuneka kuthathelwe ingqalelo ukunqanda ukonakaliswa kwePolymer.

Ukulungiswa kweekhemikhali:

Ngamanye amaxesha, ukutshintsha kweekhemikhali kweselulose Umzekelo, ukwazisa amaqela e-hydrophobic okanye ukwandisa inqanaba lokufaka endaweni yokufaka i-selsulose khebhu ngakumbi kwiinyibilikisi eziphilayo.

Izisombululo ze-mikeller:

I-surfacapes inokwenza uMilines kwisisombululo, esinokuqinaI-seluplose. Ngokuhlengahlengiswa kwe-surfactions kunye neemeko zesisombululo, kunokwenzeka ukuba inyibilike ii-sesetsese.
Ukuqukumbela, ukhetho lwendlela yokulahla ii-sesesese eeke ixhomekeke kwimiba efana nohlobo lwe-seluplose i-ether, i-strability ye-inting, kunye nenjongo yokusingqongileyo. Indlela nganye inezibonelelo zayo kunye nokusikelwa umda, kwaye abaphandi bayaqhubeka nokuphonononga iindlela ezintsha zokuphucula ukuchitheka kweseluplose
