6. Amanzi:
Umthombo: Amanzi licandelo eliphambili kwi-HPMC Synthesi, obambeleyo njengendlela yokuphendula kunye nokukhuthaza i-hydrolysis yeseluplose.
Ukulungiswa: Amanzi asetyenziswa kumanqanaba ohlukeneyo enkqubo yokwenziwa, kubandakanya i-hydrolysis ye-sellulose kunye nokuhlamba kunye namanyathelo okuhlambulula.

Inkqubo yeMveliso:
Ukuveliswa kwe-hydroxypropyl methylcelgalose ibandakanya uthotho lwamanyathelo, apho izinto ezingafunwanga ngasentla zidlala indima kwi-synthesis
Indima ephambili.

Ukulungiswa kwe-seluplose:
I-selsulose yahlulwe kwiintsinga zezityalo (i-pulp yenkuni okanye umqhaphu) kwaye iqhubeke nothotho lweenkqubo zokunciphisa ubunzima bayo, yenza kube lula ukuguqula.

Unyango lwe-Alkali:
I-seluplose inyangwa nge-sodium hydroxide ukuba yenze imeko ye-alkaline efanelekileyo yokuphendula nge-propylene oxide.

Intshayelelo kwi-HydroxyPLLYL:
I-propylene oxide yongezwa kwi-Alkali-eKali ePhezulu ukuze ikwazise amaqela e-hydroxypropy kwi-selsulose i-selbone.

Intshayelelo yeMethyl Intshayelelo:
I-methyl chloride ingeniswe kumxube wokuphendula, okukhokelela ekongezani amaqela e-methyl kwi-hydroxyproplopy.

Nxibelelana:
Sebenzisa i-hydrochloric acid ukuba ungathathi cala umxube wokuphendula ukuqinisekisa ukuba imveliso yokugqibela ayisisiseko kakhulu.

Ukuhlamba nokuhlanjululwa:
Isiphumo se-hydroxypropyl methylcelcelculose ihlanjwa kwaye ihlanjululwe ukuze isuse izinto ezingcolileyo, ezingekho mthethweni kunye neemveliso.

Ukomisa:
I-HPMC ehlanjululwe imisiwe ukuze ifumane imveliso yokugqibela, emhlophe ukuya kwi-powder emhlophe.
Izicelo ze-hydroxypropyl methylcelceluplose:
