Taw qhia

2,3-Dichlorobenzoyl Chloride Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Cov tsos mob: 2,3-Dichlorobenzoyl chloride yog xim tsis muaj xim rau lub teeb daj.

- Solubility: 2,3-Dichlorobenzoyl chloride yog soluble hauv organic solvents xws li ethers thiab cawv, tab sis insoluble hauv dej.

 

Siv:

- 2,3-Dichlorobenzoyl chloride yog ib qho tseem ceeb nyob rau hauv nruab nrab compound thiab feem ntau siv nyob rau hauv cov organic synthesis tshuaj.

- 2,3-Dichlorobenzoyl chloride kuj tuaj yeem siv los ua acylation reagent rau hloov cov pab pawg hydroxyl rau acyl pawg.

- Nws kuj tseem siv rau hauv kev npaj cov khoom siv roj hmab thiab cov ntaub ntawv polymer, ntawm lwm yam.

 

Txoj kev:

- 2,3-Dichlorobenzoyl chloride tuaj yeem tau los ntawm reacting 2,3-dichlorobenzoic acid nrog thionyl chloride. Cov tshuaj tiv thaiv yog rhuab nyob rau hauv ib qho chaw inert kom txog thaum cov reactants melted, thiab thionyl chloride maj mam ntxiv.

- Cov kev sib npaug sib npaug yog raws li hauv qab no:

C6H4(Cl)COOH + SO2Cl2 → C6H4(Cl)C(O)Cl + H2SO4

 

Cov ntaub ntawv kev nyab xeeb:

- 2,3-Dichlorobenzoyl chloride yog cov organic compound nrog qee yam tshuaj lom. Kev raug lossis nqus ntawm cov tshuaj tuaj yeem ua rau khaus thiab ua rau daim tawv nqaij, qhov muag, thiab ua pa puas.

- Thaum siv 2,3-dichlorobenzoyl chloride, kev ua pa zoo yuav tsum tau xyaum thiab siv cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb, thiab lub ntsej muag tiv thaiv yuav tsum tau siv.

- Thaum lub sijhawm khaws cia thiab tuav, cov txheej txheem tshuaj lom neeg yuav tsum tau ua raws li nruj me ntsis, thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob yuav tsum tau khaws cia tseg.

- Yog tias 2,3-dichlorobenzoyl chloride nqos los yog raug yuam kev, nrhiav kev kho mob tam sim ntawd thiab nqa cov ntaub ntawv hais txog qhov sib xyaw.
