Taw qhia
β-Naphthalene acetophenone yog cov organic compound. Nws yog ib yam khoom nrog ib tug dawb los yog lub teeb daj crystalline duab nrog ib tug peculiar aromatic tsw.
β-Naphthalene acetophenone muaj ntau yam kev siv tseem ceeb. Nws yog siv los ua cov khoom tseem ceeb pib thiab nruab nrab hauv cov organic synthesis. β-Naphthalene acetophenone tuaj yeem siv los ua cov khoom siv ntxiv hauv roj hmab, yas, xim thiab dyes.
Muaj ntau ntau txoj hauv kev rau kev npaj ntawm β-naphthalene ethyl ketone. Ib txoj hauv kev yog synthesis los ntawm methylation thiab oxidation ntawm naphthalene. Hauv cov qauv no, naphthalene yog thawj methylated rau methylnaphthalene thiab tom qab ntawd oxidized rau β-naphthalene acetophenone. β-naphthalene acetophenone tuaj yeem ua kom huv thiab muab rho tawm los ntawm txoj kev xws li distillation thiab fractionation.
Nws yog ib qho khoom siv hluav taws xob thiab yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab cua sov. Qhov thib ob, nws yuav ua rau khaus thiab puas tsuaj rau ntawm daim tawv nqaij, qhov muag, lossis tom qab noj, yog li ua tib zoo ceev faj thaum sib cuag. Cov txheej txheem kev ua haujlwm nyab xeeb rau cov tshuaj yuav tsum tau ua raws thiab cov cuab yeej tiv thaiv tsim nyog yuav tsum tau siv thiab tuav.
