Taw qhia
3-Fluorophenylhydrazine hydrochloride yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: tsis muaj xim tsis muaj kob lossis dawb crystalline hmoov.
- Solubility: Soluble hauv dej thiab me ntsis soluble hauv cawv thiab ethers.
Siv:
- 3-fluorophenylhydrazine hydrochloride yog dav siv nyob rau hauv cov organic synthesis raws li ib tug txo tus neeg sawv cev los yog reagent rau cov synthesis ntawm cov organic tebchaw xws li tshuaj tua kab, dyes, thiab tshuaj tua kab mob.
- Nws kuj tseem siv rau hauv kev npaj cov khoom siv kho qhov muag uas tsis yog-linear.
Txoj kev:
- 3-Fluorophenylhydrazine hydrochloride feem ntau yog npaj los ntawm reacting 3-fluorophenylhydrazine nrog hydrochloric acid nyob rau hauv cov kev mob tsim nyog.
- Thaum lub sij hawm cov tshuaj tiv thaiv, 3-fluorophenylhydrazine yog yaj nyob rau hauv hydrochloric acid thiab ces maj mam crystallized kom tau crystals, uas yuav recrystallized los yog lwm yam purification kauj ruam los txhim kho lub purity ntawm cov khoom.
Cov ntaub ntawv kev nyab xeeb:
- Nws tuaj yeem ua rau khaus thiab ncaj qha rau ntawm daim tawv nqaij thiab qhov muag yuav tsum zam.
- Hnav cov khoom tiv thaiv tsim nyog, xws li hnab looj tes, tsom iav, thiab lwm yam, thaum siv.
- Tsis txhob tiv tauj nrog cov tshuaj muaj zog oxidizing thiab cov kua qaub uas muaj zog tiv thaiv cov tshuaj tiv thaiv txaus ntshai.
- Thaum khaws cia thiab thauj, ua tib zoo saib xyuas cov dej noo tiv thaiv thiab tsis txhob ya raws.
- Pov tseg cov pov tseg kom raug raws li kev soj ntsuam kev nyab xeeb.
