Taw qhia

Diiodomethane. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm diiodomethane:

 

Zoo:

Cov tsos mob: Diiodomethane yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw tshwj xeeb.

Qhov ceev: Qhov ceev yog siab, txog 3.33 g / cm³.

Solubility: soluble nyob rau hauv cov organic solvents xws li cawv thiab ethers, insoluble nyob rau hauv dej.

Stability: txheeb ze, tab sis yuav decomposed los ntawm tshav kub.

 

Siv:

Kev tshawb fawb tshuaj: Diiodomethane tuaj yeem siv los ua cov tshuaj reagent hauv chav kuaj rau cov organic synthesis cov tshuaj tiv thaiv thiab kev npaj cov catalysts.

Tshuaj tua kab mob: Diiodomethane muaj cov kab mob bactericidal thiab tuaj yeem siv los ua tshuaj tua kab mob hauv qee lub sijhawm tshwj xeeb.

 

Txoj kev:

Diiodomethane feem ntau tuaj yeem npaj los ntawm:

Cov tshuaj tiv thaiv ntawm methyl iodide nrog tooj liab iodide: Methyl iodide yog reacted nrog tooj liab iodide los tsim diiodomethane.

Methanol thiab iodine cov tshuaj tiv thaiv: methanol yog reacted nrog iodine, thiab cov generated methyl iodide yog reacted nrog tooj liab iodide kom tau diiodomethane.

 

Cov ntaub ntawv kev nyab xeeb:

Toxicity: Diiodomethane ua rau khaus thiab ua rau daim tawv nqaij, qhov muag, thiab ua pa, thiab tej zaum yuav cuam tshuam rau hauv nruab nrab paj hlwb.

Kev tiv thaiv kev tiv thaiv: Hnav cov tsom iav tiv thaiv, hnab looj tes thiab lub npog ntsej muag roj thaum siv los xyuas kom muaj qhov cua zoo hauv chav kuaj.

Cia thiab tuav: Khaws rau hauv qhov chaw kaw, txias, qhov cua zoo, kom deb ntawm hluav taws thiab oxidants. Cov kua dej khib nyiab yuav tsum muab pov tseg raws li cov kev cai ib puag ncig.
