4-Valeroylbiphenyl (CAS# 42916-73-4)

Mawu Oyamba

Bifenpentanone, yemwenso amadziwika kuti diphenopylacetone, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha bifenpentanone:

Ubwino:

- Maonekedwe: Bifenpentone ndi kristalo wopanda mtundu kapena wachikasu.

- Kusungunuka: Imasungunuka mu zosungunulira zambiri za organic, monga ma alcohols ndi ether, komanso kusungunuka pang'ono m'madzi.

- Chemical katundu: Bifenpentone ali ndi mphamvu kuchepetsa katundu, ndipo monga pawiri yogwira, akhoza kutenga nawo mbali zosiyanasiyana zochita mankhwala.

Gwiritsani ntchito:

Njira:

Pali njira zingapo zopangira bifenpentanone, ndipo njira zomwe zimagwiritsidwa ntchito nthawi zambiri ndi izi:

- Benzophenone imakhudzidwa ndi acetophenone pansi pa mikhalidwe ya acidic kupanga bifenpentanone.

- Pamaso pa sodium oxychloroxysulfate, benzophenone ndi acetopyl bromoethylketone amakumana ndi etherification m'mikhalidwe yamchere kuti apeze bifenpentanone.

Zambiri Zachitetezo:

Bifenpentone nthawi zambiri imakhala yotetezeka mukamagwiritsa ntchito, koma zotsatirazi ziyenera kudziwidwa:

- Pewani kukhudza khungu ndi maso, ndipo valani zida zoyenera zodzitetezera mukazigwiritsa ntchito.

- Pewani kukhudzana ndi zinthu zoyaka moto ndi ma oxidants posunga kuti mupewe ngozi yamoto ndi kuphulika.

- Muyenera kuyang'anitsitsa mpweya wabwino panthawi yogwiritsira ntchito komanso posungira kuti musapume mpweya wake.

- Mukapuma mwangozi kapena kukhudzana ndi bifenpentanone, sambani khungu lanu nthawi yomweyo ndikupempha thandizo lachipatala.
