Qhov sib txawv tseem ceeb ntawm paraffin thiab isoparaffin yog tias paraffin yog ib tsob ntoo zoo li cov qauv uas muaj cov pa roj carbon thiab hydrogen atoms nrog ib daim ntawv cog lus ntawm carbon atoms, whereas isoparaffin yog ib tug branched-chain paraffin.
Paraffins yog alkanes, uas yog saturated hydrocarbons muaj cov tshuaj formula CnH2n + 2 (qhov twg n yog tus lej tag nrho). Isoparaffin yog ib qho derivative ntawm paraffin thiab yog ib qho tseem ceeb ua cov khoom hauv cov khoom siv tawv nqaij.
YParaffin yog dab tsi?
Paraffins yog alkanes, uas yog saturated hydrocarbons muaj cov tshuaj formula CnH2n + 2 (qhov twg n yog tus lej tag nrho). Cov no yog hu ua 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 sib cog lus. Txij li tsis muaj ob lossis peb daim ntawv cog lus, paraffins yog saturated hydrocarbons.
Daim duab 01: Paraffin Wax
Tsis tas li ntawd, cov tebchaw no 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 nrog plaub hydrogen atoms. Lub IUPAC nomenclature ntawm paraffin yog raws li Greek prefixes.
Daim duab 02: Lub Cuab Yeej Paraffin
Txhua tus paraffins tsis muaj xim thiab tsis muaj ntxhiab. Cov ntsiab lus melting thiab cov ntsiab lus boiling nce 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 cov sib xyaw gaseous. Qhov sib txawv no yog vim lawv cov ntsiab lus 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.
Isoparaffin yog dab tsi?
Isoparaffin yog ib txoj hlua txuas txuas. Nws yog ib qho tseem ceeb ntawm cov khoom tu tawv nqaij uas muaj txiaj ntsig zoo li emollient. Isoparaffin tuaj yeem ua rau daim tawv nqaij mos thiab du los ntawm kev pab cov moisturizing ntawm daim tawv nqaij barrier thiab los ntawm kev tsim ib tug semi-occlusive zaj duab xis nyob rau sab saum toj ntawm daim tawv nqaij rau kev tiv thaiv ntawm noo noo. Peb tuaj yeem siv cov khoom uas muaj isoparaffin txhua hnub yam tsis muaj kev phiv loj heev. Cov khoom xyaw no zoo dua rau cov neeg uas muaj tawv nqaij qhuav, flaky.
Isoparaffin yog hydrocarbon muab los ntawm roj av. Nws muaj nyob rau hauv ntau yam khoom tu tawv nqaij, nrog rau cov moisturizers, tshuaj pleev thaiv hnub, di ncauj khoom, foundations, ntxuav, deodorants, thiab make-up removers. Txawm hais tias nws yog cov khoom tsis ua rau khaus nrog qhov tshwm sim tsawg kawg nkaus, nws tsis haum rau cov tawv nqaij pob txuv vim nws tuaj yeem ua rau pob ntxau.
Qhov txawv ntawm Paraffin thiab Isoparaffin yog dab tsi?
Paraffins yog alkanes thiab yog saturated hydrocarbons uas muaj cov tshuaj formula CnH2n+2 (qhov twg n yog tus lej tag nrho). Lub caij no, isoparaffin yog ib qho derivative ntawm paraffin thiab yog ib qho tseem ceeb raws li cov khoom xyaw hauv cov khoom siv tawv nqaij. Ntxiv mus, qhov sib txawv tseem ceeb ntawm paraffin thiab isoparaffin yog tias paraffin yog ib tsob ntoo zoo li cov qauv uas muaj cov pa roj carbon thiab hydrogen atoms nrog ib daim ntawv cog lus ntawm carbon atoms, whereas isoparaffin yog ib tug branched-chain paraffin.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm paraffin thiab isoparaffin hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Paraffin vs Isoparaffin
Paraffin thiab isoparaffin yog cov tshuaj hydrocarbon. Paraffins yog alkanes, uas yog saturated hydrocarbons muaj cov tshuaj formula CnH2n + 2 (qhov twg n yog ib tug lej). Isoparaffin yog ib qho derivative ntawm paraffin thiab yog ib qho tseem ceeb raws li cov khoom xyaw hauv cov khoom siv tawv nqaij. Yog li ntawd, qhov sib txawv tseem ceeb ntawm paraffin thiab isoparaffin yog tias paraffin yog ib tsob ntoo zoo li cov qauv uas muaj cov pa roj carbon thiab hydrogen atoms nrog ib daim ntawv cog lus ntawm carbon atoms, whereas isoparaffin yog ib tug branched-chain paraffin.
