Kev soj ntsuam ntxaws ntawm benzaldehyde ntom
Raws li ib qho tseem ceeb organic compound nyob rau hauv kev lag luam tshuaj, benzaldehyde yog dav siv nyob rau hauv zus tau tej cov txuj lom, tshuaj thiab tshuaj intermediates. Nkag siab txog qhov ntom ntom ntawm benzaldehyde yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm zoo thaum khaws cia, thauj thiab siv. Hauv tsab xov xwm no, peb yuav tshawb xyuas kom meej txog kev paub txog benzaldehyde ntom ntom thiab piav qhia nws qhov tseem ceeb hauv kev siv tswv yim.
benzaldehyde ceev yog dab tsi?
Benzaldehyde ceev yog qhov loj ntawm benzaldehyde ib chav tsev ntim, feem ntau qhia hauv g / cm³. Qhov ceev tsis yog tsuas yog ib qho tseem ceeb ntawm cov khoom ntawm lub cev ntawm benzaldehyde, tab sis kuj yog ib qho tseem ceeb ntsuas ntawm purity thiab zoo ntawm benzaldehyde. Ceev yog ze rau qhov kub thiab kub, yog li hauv kev xyaum, nkag siab thiab kev tswj hwm ntawm Benzaldehyde yog qhov tseem ceeb los xyuas kom cov kev ua tau zoo ntawm nws cov kev ua tau zoo.
Kev sib raug zoo ntawm lub cev thiab qhov ceev ntawm benzaldehyde
Benzaldehyde (cov tshuaj formula C7H6O), tseem hu ua benzaldehyde, yog nthuav tawm raws li ib tug tsis muaj xim rau lub teeb daj kua nyob rau hauv chav tsev kub nrog ib tug muaj zog almond tsw. Nws tus qauv ceev ntawm 20 ° C yog 1.044 g / cm³. Tus nqi ceev no qhia txog cov kua dej thiab cov txheeb ze ntawm benzaldehyde nyob rau hauv chav tsev kub, yog li nyob rau hauv tus txheej txheem ntawm kev siv, qhov kev hloov ntawm kub yuav cuam tshuam qhov ceev ntawm benzaldehyde. Piv txwv li, qhov ceev ntawm benzaldehyde txo me ntsis ntawm qhov kub thiab txias vim tias qhov ntim ntawm cov kua nthuav dav thaum qhov kub nce.
Impact ntawm Benzaldehyde Ceev ntawm Daim Ntawv Thov
Kev nkag siab txog qhov ceev ntawm benzaldehyde yog qhov tseem ceeb rau nws daim ntawv thov hauv kev lag luam. Piv txwv li, nyob rau hauv zus tau tej cov flavours thiab fragrances, qhov ceev ntawm benzaldehyde txiav txim nws feem thiab homogeneity nyob rau hauv cov sib tov. Yog li ntawd, ntsuas kev ntsuas ntawm qhov ceev yog qhov tseem ceeb ntawm kev tsim qauv ua kom cov khoom lag luam zoo.
Benzaldehyde ntom kuj cuam tshuam nws txoj kev nyab xeeb thaum khaws cia thiab thauj. Cov dej siab dua yuav tsum tau ua tib zoo saib xyuas hloov thiab cov thawv xaiv thaum thauj kom tsis txhob muaj kev huam yuaj lossis thawv breakage. Los ntawm kev nkag siab qhov ceev ntawm benzaldehyde kom raug, kev cia khoom thiab kev thauj mus los tuaj yeem ua kom zoo dua los ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov khoom siv tshuaj.
Cov ntsiab lus
Qhov ceev ntawm benzaldehyde tsis yog tsuas yog ib qho ntawm cov khoom tseem ceeb ntawm lub cev ntawm benzaldehyde ua cov tshuaj lom neeg, tab sis kuj yog ib qho tseem ceeb tsis tuaj yeem tsis quav ntsej hauv nws daim ntawv thov thiab tuav. Los ntawm kev nkag siab tob txog qhov ceev ntawm benzaldehyde, peb tuaj yeem tswj hwm nws cov kev ua tau zoo hauv ntau daim ntawv thov kev lag luam kom ntseeg tau cov khoom zoo thiab kev nyab xeeb. Hauv kev xyaum, kev ntsuas qhov tseeb thiab kev tswj xyuas qhov ntom ntom kuj yog lub hauv paus rau kev txhim kho kev tsim khoom thiab ua kom muaj kev nyab xeeb. Yog li ntawd, nws yog ib qho tseem ceeb kom ua tib zoo saib xyuas qhov ceev ntawm benzaldehyde, ob qho tib si hauv chav kuaj thiab hauv kev tsim khoom.
