Inkampani ye-Toantai Selese Inkampani ikhethekileyo kuphando, uphuhliso, imveliso kunye nokukhuthaza ukuthengisa kwemveliso ye-hydropyl methmc i-hpmc ye-hpmc seluplose i-hpmc ye-HPMYL. Ukucoceka kwe-HPMC HydroxdPOpyl Methyl Selelose yesona sihloko semveliso echaphazelekayo kubavelisi kunye nabasebenzisi. Apha si-hydroxypropyl methyl abavelisi baseselupyl ukuba banike ingxelo eneenkcukacha, ndinethemba lokufunda ukunceda.
Ukuzimisela kokucoceka kwe-HPMC Hydroxropyl Methyl Sellulose
Umgaqo
I-HydroxyPOpyl Methyl Selelise HPMC i-Insmolline nge-80% ethanol. Emva kokunyibilikisa kunye nokuhlamba kangangezihlandlo ezininzi, ama-80% e-ethanol echithwe kwisampulu eyahlulwe kwaye isuswe ukuze ufumane i-hydropyl ye-hpmc.
Ri-eagent
Ngaphandle kokuba kuchazwe ngenye indlela, kuphela amaRegegementi aqinisekiswe ukuba ahlalutye kwaye anemikhono okanye amanzi okanye amanzi ococeko olwedwa uya kusetyenziswa kuhlalutyo.
I-95% ye-ethanol (GB / T 679).
I-Ethanol, i-80% isisombululo, i-dilute 95% ye-e..2.1) 840ml ngamanzi ukuya kwi-1l.
I-BMI (GB / T 12591).
Isixhobo
Izixhobo eziqhelekileyo zelebhu
Ukufudumeza kwe-magnetic shrirrer, i-skirding ubude malunga ne-3.5cm.
I-fillling ibethelelwe, i-40ml, Aperture 4.5μm ~ 9μm.
Isitya seglasi, φ10cm, umngxunya ophakathi.
Beaker, i-400ml.
Ukuhlamba amanzi rhoqo.
I-oveni, inokulawula ubushushu kwi-105 ℃ ± 2 ℃.
Inkqubo
Ngokuchanekileyo ukulinganisa isampulu ye-3G (ichanekile kwi-0.001g) kwi-Beaker eqhubekayo, faka isitya se-ethanol kwi-squirrs, faka i-thermanol ye-witner, faka i-thermanol ethambileyo, faka iqondo lokufudumeza, kwaye lugcine ubushushu kwi-60 ℃ ~ 65 ℃. Ukuvuselela imiz. 10.
Yekani ukuvuselela, beka i-beaker kwi-60 yeendawo zokuhlamba amanzi rhoqo
Yongeza i-150ml 80% ye-ethanol nge-60 ℃ ~ 65 ℃ kwi-beaker, uphinda-phinde, kwaye emva koko umbamba we-ethanol ngononophelo, kwaye uqhubeke nokuhlamba iziqulatho ezithe tyabayo. Ukunyanzelwa kufuneka kusetyenziswe ngexesha lo msebenzi kwaye ukomisa ikhekhe kufuneka kuthintelwe. Ukuba amasuntswana adlula kwi-filter, intambo kufuneka icothwe.
Qaphela: Kuya kufuneka kuqinisekiswe ukuba i-sodium chloride kwisampulu ihlanjululwe ngokupheleleyo ngama-80% ethanol. Ukuba kukho imfuneko, i-0.1MOL / l isisombululo se-Nil kwaye i-6mol / l nitric acid inokusetyenziselwa ukujonga ukuba ngaba i-finde i-i-chloride ion.
Kumaqondo obushushu egumbi, imixholo etsikwene ihlanjwe kabini nge-95% ye-ethanol kwi-50ml, kwaye ekugqibeleni ine-ethyyl mi20ml ye-Stallery. Ixesha elifanelekileyo akufuneki libe lide kakhulu. Isibetho sabekwa kwi-beaker kwaye sashushu kwibhafu ye-steam de ifumaneke ye-Etimy Mi.
Qaphela: Ukuhlamba nge-Ethyy mi kubalulekile ukuba ususe ngokupheleleyo i-ethanol evela kwinto engafakwanga. Ukuba i-ethanol ayisuswa ngokupheleleyo ngaphambi kokuba i-oveni yomisa, ukususwa ngokupheleleyo akunakwenzeka ngexesha lokumisa i-oven.
I-on esibethelwe kunye ne-beaker yabekwa kwi-oveni ngo-105 ℃ ± ukumisa i-2h, idluliselwe kwi-1h kwaye yomile i-1h kwaye i-1h kwaye yomile i-pienting de i-0.003g. Kwimeko yokwanda kobunzima ngexesha le-1h yomisa, ubunzima obuphantsi kakhulu buya kubakho.
Iziphumo zibaliwe
Ukucoceka kwe-HPMC HydroxdPOpyl Methyl Selelose yabalwa njengeqhezu le-P, kwaye ixabiso lavakaliswa njenge%
M1-Ubunzima boMbono owomileyo owomileyo, kwigram (g);
M0-Ubuninzi becandelo lovavanyo, kwigram (g);
W0-umswakama kunye nomxholo oguquguqukayo wesampulu,%.
Ixabiso le-Arithmetic le-Arithmetic le-Arithmetic lemilinganiselo emibini elifanayo incitshisiwe ibe yindawo enye ye-Desal njengesiphumo soMgangatho.
Pumbono
Umahluko opheleleyo phakathi kwemilinganiselo emibini yezimeleyo efunyenwe phantsi kweemeko zokuphinda-phinda ayikho ngaphezulu kwe-0.3%, inikezwe ukuba i-0.3% ayidluli kwi-5%.
