ethyl yog ib qho organic compound nrog cov tshuaj formula C8H6ClNO2. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw. Cov nram qab no yog lwm yam khoom ntawm lub compound:

Xwm:

- Ceev: approx. 1.28 g / ml

- Boiling point: Txog 250 ° C

- Melting point: txog 29 ° C

-Solubility: Soluble nyob rau hauv qee cov organic solvents, xws li ethanol, dichloromethane thiab ether

Siv:

- ethyl L yog dav siv los ua ib qho nruab nrab ntawm cov organic synthesis thiab yog siv rau hauv kev sib txuas ntawm cov tshuaj thiab tshuaj tua kab.

-Nws tseem tuaj yeem siv los ua cov kuab tshuaj thiab cov catalyst hauv cov organic synthesis cov tshuaj tiv thaiv.

Method: Txoj kev npaj ntawm

ethyl L feem ntau suav nrog cov kauj ruam hauv qab no:

1. React 6-chloropyridine nrog sodium cyanide los tsim 6-chloropyridine -2-carbonitrile.

2. React 6-chloropyridine-2-carbonitrile nrog cawv los tsim 6-chloropyridine-2-carbonitrile cawv.

3. Thaum kawg, 6-chloropyridine-2-nitrile cawv yog reacted nrog acid los tsim ethyl L.

Cov ntaub ntawv kev nyab xeeb:

ethyl L yog irritating thiab tej zaum yuav ua rau khaus ntawm daim tawv nqaij, qhov muag thiab ua pa ib ntsuj av. Yog li ntawd, cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb thiab cov cuab yeej tiv thaiv ua pa yuav tsum tau hnav thaum siv tshuaj.

Tsis tas li ntawd, qhov sib xyaw ua ke kuj tseem yog nplaim taws thiab yuav tsum tau ceev kom deb ntawm cov nplaim taws thiab qhov kub thiab txias. Kev coj ua nyab xeeb yuav tsum tau ua raws li thaum khaws cia thiab tuav cov khoom.
