4 4'- Dimethoxybenzophenone (CAS # 90-96-0)

Taw qhia

4,4′-Dimethoxybenzophenone, tseem hu ua DMPK lossis Benzilideneacetone dimethyl acetal, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw no:

Zoo:

4,4'-Dimethoxybenzophenone yog ib qho xim tsis muaj xim daj daj daj nrog cov aroma ntawm benzene. Nws yog flammable, muaj qhov ceev dua, thiab yaj hauv cov organic solvents xws li ethanol, ethers, thiab ketones. Nws tsis ruaj tsis khov rau huab cua thiab lub teeb thiab tuaj yeem raug oxidation tshwm sim.

Siv:

4,4′-dimethoxybenzophenone feem ntau yog siv los ua catalyst lossis reagent hauv organic synthesis thiab muaj kev ua haujlwm siab. Hauv cov organic synthesis, nws tuaj yeem siv rau hauv kev npaj ntawm aldehydes, ketones, thiab lwm yam.

Txoj kev:

Txoj kev npaj ntawm 4,4'-dimethoxybenzophenone tuaj yeem ua tiav los ntawm cov tshuaj tiv thaiv condensation ntawm dimethoxybenzosilane thiab benzophenone. Dimethoxybenzosilane yog reacted nrog sodium borohydride kom tau boranol, thiab ces condensed nrog benzophenone kom tau 4,4'-dimethoxybenzophenone.

Cov ntaub ntawv kev nyab xeeb:

4,4′-Dimethoxybenzophenone yog khaus rau ntawm daim tawv nqaij thiab tej zaum yuav ua rau khaus ntawm lub qhov muag thiab ua pa ib ntsuj av. Kev tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab lub tshuab ua pa yuav tsum tau hnav thaum tuav thiab siv. Thaum lub sij hawm cia, nws yuav tsum tau khaws cia rau hauv qhov chaw txias, qhuav, deb ntawm ignition thiab oxidants. Thov ua raws li cov txheej txheem ua haujlwm nyab xeeb thiab ua raws li tag nrho cov kev cai thiab cov cai. Thaum muaj xwm txheej, kev ntsuas xwm txheej ceev yuav tsum tau ua tam sim ntawd.
