3, {4- dimethoxybenzhoxenone (CAS 4038-14-6}) yog qhov tseem ceeb rau kev noj tshuaj hauv nruab nrab. Nws cov qauv molecular muaj ob pawg benzene muaj ob pawg, thiab txoj haujlwm thib 4 ntawm ib qho ntawm cov pab pawg benzene tau hloov los ntawm cov pab pawg me me. Cov mis molecular yog c₁₅h₁₄o₃, thiab cov molecular hnyav yog 242.27 g \/ mol.
3, {4- dimethoxybenzhobeno zoo li lub teeb daj ua hmoov, nrog lub ntsej muag melting ntawm {2}} degree ntawm 335 degree. Nws yog me ntsis soluble hauv dej tab sis yooj yim soluble hauv cov kuab tshuaj yeeb yaj kiab xws li ethanol thiab acetone.

Siv:

3, {4- dimethoxybenzhobenontone rau cov hluavtaws tseem ceeb rau cov tshuaj tua kab mob methylopa metyl esyl esyroride. Cov nyhuv synergistic ntawm cov pab pawg methoxy thiab carbonyl tuaj yeem tiv thaiv Central -drenergic recenors thiab txhim kho dopaminergic neurotransmission muaj nuj nqi.
Nyob rau hauv cov ntaub ntawv txuj ci, cov ntais ntawv no tuaj yeem siv los ua tus kws yees duab hauv UV-kho cov txheej txheem. Tom qab nqus cov teeb ci ulaviolet, nws tsim tawm cov dawb radicals los pib polymerization kev tawm tsam. Nws kuj tseem siv tau los ua ke los ntawm cov khoom siv ua kua crystal los txhim kho cov lus teb kom ceev thiab sib piv ntawm cov khoom siv.

Txoj kev npaj:

3, {4- dimethebzybenzhodone tuaj yeem npaj los ntawm cov tshuaj tiv thaiv hws ntawm benzophenone nrog methanol thiab formic acid nyob rau hauv lub xub ntiag ntawm ib acid catalyst. Cov tshuaj tiv thaiv yog feem ntau nqa tawm ntawm qhov kub thiab siab. Cov txheej txheem cuam tshuam benzophenone, methanol, thiab formic acid, ua raws li ntawm ntxiv ntawm cov acid catalyst. Tom qab cov tshuaj tiv thaiv, cov kauj ruam lim kom muaj cov khoom ntshiab kom tau txais cov khoom ntshiab.

Tam sim no peb cov khoom raug xa tawm mus rau ntau dua 30 lub teb chaws xws li Holland, Is Nrias teb, Australia muaj lub koob npe nrov hauv International Arena. Peb lub tuam txhab tau tsim kev nrawm thiab tam sim no tau dhau los ua tus neeg yuav khoom ib qho thiab cov muab kev pabcuam rau ntau tus neeg siv khoom thoob ntiaj teb. Ntsib ntxiv cov kev kawm thiab cov kev sib tw yav tom ntej, peb yuav ua kom muaj kev lag luam tshiab thiab pragmatic, thiab ua rau muaj kev siv zog.

Peb yuav ua haujlwm ua ke kom ua tiav qhov teeb meem yeej. Peb yuav yog koj tus khub zoo.

Koj puas tuaj yeem tsim koj cov khoom rau peb cov lus qhia tshwj xeeb?

Yog lawm, yog tias koj tuaj yeem ua tau peb qhov kev txiav txim yam tsawg kawg nkaus, cov xim ntawm cov khoom tuaj yeem kho tau.

Koj muab cov ntaub ntawv dab tsi?

Feem ntau, peb muab cov npe xa mus rau, cov npe thauj khoom, daim ntawv pov thawj, yog tias koj lub lag luam muaj txhua yam tshwj xeeb, thov qhia rau peb paub.

Qhov chaw nres nkoj ntawm chaw thau khoom nyob qhov twg?

Feem ntau Tianjin chaw nres nkoj lossis Qingdao chaw nres nkoj.
