Qhov sib txawv tseem ceeb ntawm avobenzone thiab benzene yog tias avobenzone yog cov khoom siv hauv cov khoom siv tshuaj pleev thaiv hnub, qhov benzene tsis yog siv los ua cov khoom siv tshuaj pleev thaiv hnub.
Avobenzone thiab benzene yog cov organic tshuaj lom neeg tseem ceeb uas muaj cov tshuaj sib txawv thiab lub cev sib txawv nrog rau kev siv sib txawv. Kab lus no piav txog lawv cov khoom thiab cov kev siv sib txawv.
Avobenzone yog dab tsi?
Avobenzone yog cov organic compound uas muaj cov tshuaj formula C20H22O3 Nws yog cov khoom siv roj-soluble uas muaj txiaj ntsig zoo hauv cov khoom siv tshuaj pleev thaiv hnub rau kev nqus ntawm tag nrho cov spectrum ntawm UVA rays. Nws zoo nkaus li muaj xim tsis muaj kob los yog dawb dawb rau yellowish crystalline hmoov uas muaj ntxhiab tsw. Ntxiv mus, nws tuaj yeem yaj hauv isopropanol, dimethyl sulfoxide, decyl oleate, capric acid, triglycerides, thiab lwm yam roj. Tsis tas li ntawd, nws tsis yog dej-soluble.
Daim duab 01: Cov Qauv Tshuaj ntawm Avobenzone
Peb tuaj yeem npaj avobenzone los ntawm cov tshuaj tiv thaiv ntawm 4-tert-butylbenzoic methyl ester nrog 4-methoxyacetophenone hauv toluene nyob rau hauv muaj sodium amide los ntawm Claisen Condensation.
Thaum xav txog chemistry ntawm cov tshuaj no, nws yog dibenzoyl methane derivative uas yog soluble hauv roj. Cov molar loj ntawm cov tshuaj no yog 310.4 g / mol. Nws muaj hydrogen daim ntawv cog lus lees txais suav ntawm 3, tab sis cov nyiaj pub dawb hydrogen suav yog 0. Lub melting point ntawm no compound yog 83.5 degrees Celsius, thiab solubility ntawm cov dej yog tsis zoo, yog li peb yuav hais tias nws yog insoluble nyob rau hauv dej. Tab sis nws yog soluble hauv isopropanol, decyl oleate, capric triglyceride, thiab castor roj. Ntxiv mus, nws ruaj khov nyob rau hauv cov xwm txheej muab.
Benzene yog dab tsi?
Benzene yog cov organic compound uas muaj cov tshuaj formula C6H6 Cov organic compound no muaj 6-tus tswv cuab lub nplhaib, thiab tag nrho. cov tswv cuab yog carbon atoms. Txhua ntawm cov pa roj carbon atom txuas nrog hydrogen atom. Txij li cov compound no tsuas muaj carbon thiab hydrogen atoms, nws yog hydrocarbon. Ntxiv mus, cov compound no ib txwm tshwm sim raws li cov khoom siv ntawm cov roj crude.
Daim duab 02: Cov Qauv Tshuaj ntawm Benzene
Cov molar loj ntawm benzene yog 78.11 g / mol. Nws melting point thiab boiling point yog 5.53 ° C thiab 80.1 ° C, feem. Benzene yog cov kua tsis muaj xim nyob rau hauv chav tsev kub. Tsis tas li ntawd, nws yog ib qho aromatic hydrocarbon. Raws li qhov tshwm sim, nws muaj qhov tsw ntxhiab tsw. Ntxiv mus, raws li kev txiav txim X-ray diffraction, tag nrho cov ntawv cog lus ntawm rau cov pa roj carbon atom muaj qhov ntev zoo sib xws. Yog li ntawd, nws muaj cov qauv nruab nrab. Peb hu nws ua "hybrid qauv" vim hais tias, raws li daim ntawv cog lus tsim, yuav tsum muaj kev sib hloov ib daim ntawv cog lus thiab ob daim ntawv cog lus ntawm cov pa roj carbon atoms. Tom qab ntawd, cov qauv benzene tiag tiag yog tshwm sim los ntawm ntau cov qauv resonance ntawm benzene molecule.
Qhov txawv ntawm Avobenzone thiab Benzene yog dab tsi?
Avobenzone thiab benzene muaj cov ntawv thov sib txawv raws li lawv cov tshuaj sib txawv thiab lub cev. Avobenzone yog ib qho organic compound uas muaj cov tshuaj formula C20H22O3 thaum benzene yog cov organic compound. muaj cov tshuaj formula C6H6. Qhov sib txawv tseem ceeb ntawm avobenzone thiab benzene yog tias avobenzone yog cov khoom siv hauv cov khoom siv tshuaj pleev thaiv hnub, qhov benzene tsis yog siv los ua cov khoom siv tshuaj pleev thaiv hnub. Ntxiv mus, avobenzone zoo nkaus li muaj xim tsis muaj xim lossis xim dawb rau daj daj crystalline hmoov, thaum benzene zoo nkaus li ntshiab, tsis muaj xim rau lub teeb daj kua hauv chav sov.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm avobenzone thiab benzene hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – Avobenzone vs Benzene
Avobenzone thiab benzene yog cov organic sib xyaw nrog cov khoom sib txawv thiab kev siv. Qhov sib txawv tseem ceeb ntawm avobenzone thiab benzene yog tias avobenzone yog cov khoom siv hauv cov khoom siv tshuaj pleev thaiv hnub, thaum benzene tsis siv los ua cov khoom xyaw hauv cov tshuaj pleev thaiv hnub. Ntxiv mus, lawv muaj qhov sib txawv raws li qhov sib txawv loj thiab cov ntsiab lus kub.
