Qhov sib txawv tseem ceeb ntawm paraben thiab paraffin yog tias paraben muaj txiaj ntsig zoo hauv kev khaws cov tshuaj pleev ib ce, thaum paraffin muaj txiaj ntsig hauv kev ua cov khoom glossy lossis muab cov khoom siv roj ntau dua.
Parabens yog cov organic tebchaw uas muaj ib pawg ua haujlwm ester thiab ib pawg hydroxyl. Paraffin tebchaw, ntawm qhov tod tes, yog alkanes uas tuaj yeem piav qhia tias yog cov hydrocarbons saturated muaj cov tshuaj formula CnH2n + 2.
YParaben yog dab tsi?
Parabens yog cov organic tebchaw uas muaj ib pawg ua haujlwm ester thiab ib pawg hydroxyl. Parabens muaj ntau, thiab lawv muaj txiaj ntsig zoo li cov tshuaj tua kab mob hauv kev lag luam tshuaj, kev lag luam tshuaj pleev ib ce, thiab lwm yam. Cov qauv tshuaj ntawm cov tshuaj no muaj lub nplhaib benzene txuas nrog ester pawg thiab hydroxyl pawg ntawm para txoj haujlwm. Yog li, cov tshuaj no hu ua esters ntawm para-hydroxybenzoic acid.
Muaj cov khoom lag luam muaj parabens uas yog cov khoom siv hluavtaws. Txawm li cas los xij, kuj tseem muaj qee cov ntaub ntawv paraben uas zoo ib yam rau cov parabens peb tuaj yeem pom hauv qhov xwm txheej. Txoj kev tsim cov tshuaj parabens yog los ntawm esterification ntawm para-hydroxybenzoic acid nrog cawv xws li methanol, ethanol, thiab n-propanol.
Peb tuaj yeem pom cov tshuaj parabens ua cov tshuaj tiv thaiv zoo hauv ntau hom qauv. Cov tshuaj no thiab lawv cov ntsev muaj txiaj ntsig zoo vim lawv cov kab mob bactericidal thiab fungicidal. Peb tuaj yeem pom cov khoom sib xyaw no hauv cov tshuaj zawv plaub hau, cov khoom lag luam muag moisturizers, shaving gels, lubricants tus kheej, pleev, thiab tshuaj txhuam hniav. Qee zaum, peb tuaj yeem siv cov khoom sib xyaw ua zaub mov noj thiab.
YParaffin yog dab tsi?
Paraffin compounds yog alkanes uas tuaj yeem piav qhia raws li saturated hydrocarbons nrog cov tshuaj formula CnH2n+2 (qhov twg n yog ib tag nrho tus lej). Peb tuaj yeem hu cov tebchaw hydrocarbons vim lawv muaj C thiab H atoms. Tag nrho cov atoms no txuas rau ib leeg los ntawm ib qho kev sib cog lus. Txij li tsis muaj ob lossis peb daim ntawv cog lus, paraffins yog saturated hydrocarbons.
Ntxiv mus, paraffin tebchaw yog ib pawg dav ntawm cov organic molecules. Peb tuaj yeem sau npe rau lawv raws li tus naj npawb ntawm cov pa roj carbon atom thiab cov pab pawg sab uas lawv muaj. Qhov tsawg tshaj plaws alkane yog methane. Hauv methane, lub hauv paus carbon atom khi rau plaub hydrogen atoms. IUPAC nomenclature ntawm paraffin yog raws li Greek prefixes.
Txhua tus paraffins tsis muaj xim thiab tsis muaj ntxhiab. Lawv cov ntsiab lus melting thiab cov ntsiab lus kub nce ntxiv nrog qhov nce ntawm cov pa roj carbon atoms. Raws li tus qauv ntsuas kub thiab siab, qee qhov ntawm lawv yog cov kua dej, thaum qee qhov yog gaseous compounds. Qhov sib txawv no yog vim lawv cov ntsiab lus kub sib txawv. Ntxiv mus, alkanes qhia isomerism. Paraffin molecule tej zaum yuav muaj cov qauv isomerism los yog stereoisomerism raws li nws cov qauv thiab spatial kev npaj ntawm lub molecule.
Qhov txawv ntawm Paraben thiab Paraffin yog dab tsi?
Parabens thiab paraffins yog cov organic tebchaw tseem ceeb. Qhov sib txawv tseem ceeb ntawm paraben thiab paraffin yog tias parabens muaj txiaj ntsig zoo hauv kev khaws cov tshuaj pleev ib ce, thaum paraffins muaj txiaj ntsig zoo hauv kev ua cov khoom glossy lossis muab cov khoom siv roj ntau dua. Ntxiv mus, paraben yog tsim los ntawm esterification ntawm para-hydroxybenzoic acid nyob rau hauv lub xub ntiag ntawm cawv thaum paraffin yog tau los ntawm roj av los ntawm dewaxing lub teeb lubricating roj stocks.
Cov hauv qab no qhia txog qhov sib txawv ntawm paraben thiab paraffin hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Paraben vs Paraffin
Parabens yog cov organic tebchaw uas muaj ib pawg ua haujlwm ester thiab ib pawg hydroxyl. Paraffin compounds yog alkanes thiab saturated hydrocarbons uas muaj cov tshuaj formula CnH2n+2 Qhov sib txawv tseem ceeb ntawm paraben thiab paraffin yog tias parabens muaj txiaj ntsig zoo hauv kev khaws cia. tshuaj pleev ib ce, whereas paraffins yog pab tau nyob rau hauv ua cov khoom glossy los yog muab ntau lubricating zog.
