Igama lendlela

Umda wesicelo: Le ndlela isebenzisa i-hydroxypropoxy yendlela yokumisela umxholo we-hydroxypropoxy in hypromellose. Le ndlela isebenza kwi-hypromellose.

Umgaqo wendlela:Bala iUmxholo we-hydroxypropoxy kwimveliso yovavanyo ngokwendlela yokumiselwa kwe-hydroxypropoxy.

Regent:

I-1. Iipesenti ezingama-30 (G / G) I-chromium yesisombululo

I-2. Hydroxide

I-3. I-Phenolfthalein yesalathisi

I-4. I-Sodium Bicarbonate

I-5. I-dilute sulfuric acid

I-6. I-potassium idider

I-7. I-Sodium Tioulical Timorical isisombululo (i-0.02MOL / L)

8. Isisombululo sesalathisi

Izixhobo:

Ukulungiselela isampulu:

I-1. Isodium ye-sodium hydroxide (0.02MOL / L)

Ukulungiselela: Thatha i-5.6ml yesisombululo se-sodium ye-sodium ye-sodium ye-sodium ye-sodium, yongeza amanzi abandayo ane-boyiweyo ukuba izenze i-1000ml.

Ukulinganisa: Thatha malunga ne-6G ye-potassium ye-chatdrogen phthatalate ye-phthatalate ye-105 ° C ukuya kubunzima, yilinganise ngokuchanekileyo, yongeza i-50ml yamanzi abandayo, anyibilikiswe ukunyibilikisa kangangoko kunokwenzeka; Yongeza amaconsi ama-2 e-phenolfthalein yesalathisi, sebenzisa le cebiso lamanzi, xa usondela kwinqaku lesiphelo, i-potassium hydhalate ifanele ichithwe ngokupheleleyo, kwaye inesisombululo ipinki. Yonke i-1ml ye-sodium ye-sodium hydroxide (1mol / l) ilingana nama-20.42mg ye-potassium hydrhagelate. Bala uxinzelelo lwesisombululo esekwe ekusetyenzisweni kwesisombululo kunye nenani le-potassium hhthagelate ethathwe. Ubungakanani bexesha eli-5 amaxesha ukwenza uxinzelelo lwe-0.02mol / l.

Ukugcina: yibeke kwibhotile yeplastiki yePolythyethne kwaye ugcine ukutywinwa; Kukho imingxunya emi-2 kwiplagi, kwaye i-1 ye-1 yeglasi ifakwe kumngxunya ngamnye, ityhubhu eyi-1 iqhagamshelwe ngetyhubhu ye-soda, kwaye i-1 ityhubhu isetyenziselwa ukuncancisa ulwelo.

2. I-phenolphthalein isalathisi se-1G ye-1G ye-phenolphthalein, yongeza i-100ml ye-ethanol ukuze inyibilike

I-3. I-Sodium Tieoullity ye-SOOLOLLFEATER (0.02MOL / L) Ukulungiselela: thatha i-26g ye-SODIUM ye-SODIIM ye-ADDDAROR, yongeza isixa esifanelekileyo se-odious therbor, inyibilikisi, kwaye ijikeleze inyanga enye isihluzo. Ukulinganisa: Thatha malunga ne-0.15g ye-potassium ye-charsium dichissromate eyomileyo nge-120 ° C ngomthwalo oqhubekayo, yongeza ibhotile ye-I-I-I-I-I-I-I-I-I-I-I-I-I-POTASELUM, yongeza kancinci ukuze unyibilike, yongeza I-40ml ye-diluturic acid, inyikima kakuhle kwaye itywina ngokuqinileyo; Emva kwemizuzu eli-10 kwindawo emnyama, yongeza i-250ml yamanzi ukuze ichithelwe, kwaye xa isisombululo sinesisombululo esikufutshane, yongeza isigqibo se-starch yesitayile, kwaye sibe luhlaza isetyenziswa njengokulungiswa kwetyala elingenanto. Yonke i-1ml ye-sodium ye-sodium ye-sodium (0.1lM / L) ilingana ne-4.903G ye-potassium dichicomama. Bala uxinzelelo lwesisombululo ngokwendlela yokusetyenziswa kwesisombululo kunye nesixa se-potassium dichismamate. Ubungakanani bexesha eli-5 amaxesha ukwenza uxinzelelo lwe-0.02mol / l. Ukuba iqondo lobushushu legumbi lingaphezulu kwe-25 ° C, iqondo lobushushu lesicombululo lokuphendula kunye namanzi okusela kufuneka kuthotyelwe malunga ne-20 ° C.

I-4. Isisombululo sesalathisi sithatha isisombululo se-0.5g se-starch enyibilikayo, yongeza i-5ml yamanzi kwaye ivuselele kakuhle, iqhubekeke i-Toula i-2ml yamanzi, iqhubeke ipholile, igalele i-supermaant, kwaye ilungile.

Esi sisombululo kufuneka silungiswe ngokutsha ngaphambi kokusetyenziswa.

Amanyathelo okusebenza: Thatha i-0.1g yale mveliso, ilinganise ngokuchanekileyo, yibeke kwibhotile yokudibanisa D, yongeza i-10ml ye-10ml ye-30% ye-CADMIUR TRIKISIUR TOCHEMINIUM TRIKISIUR. Gcwalisa ityhubhu ye-Steam Bing b ngamanzi ukuya kwiNtlawulo, kwaye uqhagamshele iYunithi yokuHamba. Ukuntywila bobabini B kunye no-D kwi-oyile yeoyile (inokuba yi-Glycerin), yenza inqanaba le-wolting lokuhlanjwa kwe-oyile ngokuhambelana nebhotile ye-CADMIUR kwiBhotile D, kwaye ukuba kukho imfuneko, vumelana Umjelo we-nitrogen hamba kwaye ulawule ireyithi yokuhamba uye kwi-1 bubble ngomzuzwana. Within 30 minutes, raise the temperature of the oil bath to 155ºC, and maintain this temperature until 50 mL of the distillate is collected, remove the condenser tube from the fractionation column, rinse with water, wash and incorporate into the collected solution, add 3 Isisombululo se-phenolfthalein yesalathisi, kunye nexabiso kwixabiso le-pH ngu-6.9-7.1 (irekhodiwe yi-0.5g ye-WODIUM BODIUM BIDFRIC AID, mayime Kuveliselwa i-carbon diokbon diokside, yongeza i-1.0g ye-potassium ididen, kwaye itywine, yongeza i-1ml yesisombululo se-Starch Staturling (i-0.02l / l) ukuya Inqaku lokugqibela, Rekhoda i-v2 yodlelo v2 (ml). Kolunye uvavanyo olungenanto, shicilela i-VOGOSS VA kunye ne-VB (ML) yeSodium yeSodium yeSodium Hydroxide (i-0.02MOL / L) kunye neSodium yeSisombululo seSodiollite (0.02l / l) ngokulandelelana.
