Taw qhia
m-Tolylhydrazine hydrochloride (m-Tolylhydrazine hydrochloride) yog cov organic tebchaw nrog cov tshuaj formula C7H10N2 · HCl. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev tsim thiab cov ntaub ntawv kev nyab xeeb:
Xwm:
-Zoo: Dawb crystalline khoom
- melting point: 180-184 ℃
-Solubility: Soluble nyob rau hauv dej thiab cawv solvents, me ntsis soluble nyob rau hauv ether solvents
Siv:
- m-Tolylhydrazine hydrochloride tuaj yeem siv los ua tus thawj coj rau kev hloov pauv hlau hauv cov organic synthesis thiab siv los npaj ntau yam sib xyaw uas muaj nitrogen.
-Nws kuj tseem siv tau ua fluorescent sojntsuam, dye, tshuaj intermediate, thiab lwm yam.
Txoj Kev Npaj:
- m-Tolylhydrazine hydrochloride tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm toluidine thiab hydrazine. Ua ntej, toluidine yog tov nrog ntau tshaj acetic acid thiab hydrochloric acid thiab rhuab mus boiling; ces hydrazine ntxiv, cua sov yog txuas ntxiv, thiab thaum kawg cov khoom yog crystallized los ntawm txias.
Cov ntaub ntawv kev nyab xeeb:
- m-Tolylhydrazine hydrochloride yog khaus, yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Yog tias koj tau ntsib nrog cov khoom no, yaug tam sim ntawd nrog dej.
-Tsis txhob sib cuag nrog oxidants thaum siv thiab khaws cia kom tsis txhob muaj hluav taws kub thiab tawg.
-Thaum muaj kev ua haujlwm tsis zoo, yuav tsum siv cov cuab yeej tiv thaiv tsim nyog, xws li cov hnab looj tes kuaj thiab tsom iav.
Nco tseg: Cov ntaub ntawv no tsuas yog siv rau kev siv xwb thiab tsis sawv cev rau kev nyab xeeb thiab raug ntawm kev siv cov khoom siv. Ua ntej siv cov tshuaj lom neeg, nco ntsoov nyeem thiab ua raws li cov cai tswj kev nyab xeeb thiab kev tuav pov hwm, thiab siv cov kev tiv thaiv tsim nyog.
