Taw qhia

Benzyl mercaptan yog ib qho organic compound, thiab cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm benzyl mercaptan:

 

Zoo:

1. Cov tsos thiab tsw: Benzyl mercaptan yog cov xim tsis muaj xim rau daj daj daj nrog cov ntxhiab tsw zoo ib yam li cov ntxhiab tsw corrosive.

2. Solubility: Nws yog soluble hauv organic solvents xws li ether thiab cawv, thiab me ntsis soluble hauv dej.

3. Kev ruaj ntseg: Benzyl mercaptan yog qhov ruaj khov rau cov pa oxygen, acids thiab alkalis, tab sis yooj yim oxidized thaum khaws cia thiab cua sov.

 

Siv:

Raws li cov khoom siv raw rau cov tshuaj synthesis: benzyl mercaptan tuaj yeem siv rau hauv cov organic synthesis cov tshuaj tiv thaiv, xws li txo tus neeg sawv cev, sulfiding tus neeg sawv cev thiab reagent hauv organic synthesis.

 

Txoj kev:

Muaj ntau ntau txoj hauv kev los npaj benzyl mercaptan, thiab ntawm no yog ob txoj hauv kev uas feem ntau siv:

1. Catechol txoj kev: catechol thiab sodium sulfide reacted los tsim benzyl mercaptan.

2. Benzyl cawv txoj kev: Benzyl mercaptan yog synthesized los ntawm reacting benzyl cawv nrog sodium hydrosulfide.

 

Cov ntaub ntawv kev nyab xeeb:

1. Ua kom khaus khaus ntawm daim tawv nqaij thiab qhov muag: Benzyl mercaptan tuaj yeem ua rau khaus thiab liab thaum nws los rau ntawm daim tawv nqaij. Yog tias nws los rau hauv qhov muag, nws tuaj yeem ua rau kub hnyiab.

2. Tsis txhob oxidation thaum lub sij hawm thauj mus los thiab cia: Benzyl mercaptan yog ib tug compound uas oxidizes yooj yim thiab spoils yooj yim thaum raug huab cua los yog oxygen. Cov huab cua yuav tsum raug zam thaum thauj thiab khaws cia.

3. Kev tiv thaiv tsim nyog yuav tsum tau ua: Cov iav tiv thaiv, hnab looj tes thiab khaub ncaws tiv thaiv yuav tsum hnav thaum ua haujlwm. Ua haujlwm hauv qhov chaw uas muaj cua zoo thiab tsis txhob nqus cov pa thiab plua plav.
