Iindlela zovavanyo

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 Tieoulling isisombululo (i-0.02mol / L) Ukulungiselela: thatha i-26g ye-sodium ye-niodium ye-onbondate, yongeza isixa esifanelekileyo se-onhydl sodium, kwaye ubeke i-filter yenyanga enye. Ukulinganisa: Thatha malunga ne-0.15g ye-potassium ye-ratassium dichichromate yomiswe nge-120 ° C ngomthwalo oqhubekayo, yongeza kakuhle i-i-i-i-i-Itch, i-Shake kakuhle i-tid sulthe acid, itywina kakuhle itywina; Emva kwemizuzu eli-10 kwindawo emnyama, yongeza i-250ml yamanzi ukuze ichithelwe, kwaye xa isisombululo sinesisombululo sesalathiso, songeza isitayile esiluhlaza, kwaye isisibiso sisetyenziswa njengolungiso lovavanyo olungenanto. 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.

4. Isisombululo sesalathisi sithatha isisombululo se-0.5g se-starch enyibilikayo, yongeza i-5ml yamanzi kwaye ivuselele i-100ml yamanzi abilayo, emva koko ipholile, igaleleke kakhulu, kwaye igqityiwe.

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 (kunokuba yi-Glycerin), yenza inqanaba le-olwelo lokuhlanjwa kwe-oyile kwibhombu ye-CADMIUR kwiBhowle kwi-BUBBN ukuya kwi-1 yesibini kwi-BUBBLE kwi-1 yesibini kumzuzwana. Ngaphakathi kwemizuzu engama-30, phakamisa iqondo lokuhlambela leoyile ukuya kwi-155ºC, kwaye ugcine i-50 ml ye-Trieddhthalein yesahlulo se-phenolfhalein ye-6.9-7.1. . Inqaku, urekhode 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.
