Yenziwa njani i-hydroxlyproploplopcelcelcelceluplose eyenziwe njani?

I-Hydroxypropylcelcelculose (HPC) yi-polymer eguquguqukayo esetyenziswa kumashishini ahlukeneyo, kubandakanya amayeza, cosmetics, ukutya, kunye neemveliso zononophelo lomntu. Ithathwe kwi-sellyulose, i-PolysacchaacCreacchaacchaacchaacchaaccharaide efumaneka kwiindonga zeseli ezityalo. Inkqubo yemveliso ibandakanya amanyathelo aliqela, kubandakanya ukucocwa, i-ether, kunye nokomisa.

Intshayelelo
I-Hydroxypropylcelcelculose yeyakwintsapho ye-Selesese Tele, ezifumanekayo ngokutshintsha imichiza. I-sellyulose yi-biopolymer eyenziwe ngokuphindaphinda i-β (1 → 4) Glycosidic Bonds. Its abundance in nature and renewable nature make it an excellent starting material for the production of various derivatives like hydroxypropylcellulose.

Inkqubo yemveliso:
Ulukhetho lwezinto ezibonakalayo:
Inyathelo lokuqala ekwenzeni i-hydropylcelcelcelculose iquka ukukhetha ukukhetha i-selsulose ekumgangatho ophezulu njengezixhobo ezibukhali. I-seluplose iqhele ukufunyanwa kwiPulp Pulp okanye i-Cotton Lists, zombini ezityebileyo kwiintsinga zeselfowuni.

Ukuhlanjululwa kweLwimi:
I-sellulose ekhethiweyo ihlambulula ukucoca ukususa ukungcola njenge-LIGIN, HEMOSE, kunye nezinye izinto ezingezizo zeselfowuni. Eli nyathelo liqinisekisa umgangatho nobunyulu lwemveliso yokugqibela.

I-ether:
Isiqinisekiso selona nqanaba liphambili kwimveliso ye-hydroxyproploploplose. Kule nkqubo, i-seluplose iguqulwe ngamachiza ngokusabela nge-propylene oxide phambi komgangatho wesigqibo, ngokwesiseko esifana neSodium hydroxide okanye potassium hydroxide. Iziphumo zokuphendula zikhokelela ekufakweni kweqela le-hydroxyl (---) kwii-selsulose Chains kunye namaqela e-hydroxypropyl

Ukungathathi cala kunye nokuhlamba:
Emva kokuthumeza, umxube wokuphendula awunamacala onke ukuba asuse i-Alkali engaphezulu njengeyona nto iphambili. Oku kufezekiswa ngokudibanisa i-acid efana ne-hydrochloric acid okanye i-sulfuric acid. Umxube ongathathi cala emva koko uhlanjwe ukuze ususe nayiphi na into engcolileyo kunye neemveliso.

Ukomisa kunye nokugaya:
I-hydropylcelcelcelcelcelsele ye-hydropylcelose yomisiwe yeyomisiwe isuse ukufuma kwaye ifumane umxholo wokufuma omfuneko ofanelekileyo ukuqhubekeka nokugcina. Ihlala incitshiswa ukufezekisa ubungakanani obufunekayo kwaye uphucule iipropathi zayo zokuhamba.

Ulawulo lwemeko:
Kuyo yonke inkqubo yokuvelisa, amanyathelo olawulo lomgangatho asetyenziswe ukuqinisekisa ukuba imveliso yokugqibela ifezekisa inkcazo efunekayo ngokubhekisele kubunyulu, uVenkile, ubukhulu becala, kunye neminye imilinganiselo efanelekileyo. Iindlela zokuhlalutya ezifana ne-chromatography, spectroscopy, kunye nokuboniswa zihlala zisetyenziselwa uvavanyo lomgangatho.
