Qhov sib txawv tseem ceeb ntawm paraffinic thiab naphthenic yog cov tshuaj paraffinic muaj alkanes thaum cov tshuaj naphthenic muaj cyclic aliphatic hydrocarbons.
Lub sij hawm paraffinic yog hais txog cov khoom uas muaj paraffin compounds, whereas lub sij hawm naphthenic yog hais txog cov tshuaj muaj naphthene. Peb feem ntau siv cov ntsiab lus no hauv cov organic chemistry thiab hauv kev lag luam chemistry. Paraffins yog alkanes thaum naphthenes yog cyclic aliphatic hydrocarbons.
Paraffinic yog dab tsi?
Lo lus paraffinic yog hais txog cov tshuaj muaj paraffins. Paraffins yog alkanes. Cov no yog acyclic saturated hydrocarbons. Ntxiv mus, cov qauv ntawm paraffins yog CnH2n + 2 Tsuas muaj ib daim ntawv cog lus ntawm carbon atoms, thiab cov molecule muaj cov qauv ntoo. Yog li ntawd, tag nrho cov carbon atoms nyob rau hauv paraffinic tebchaw yog sp3 hybridized. Yog li, qhov no txhais tau tias txhua cov pa roj carbon atom muaj plaub daim ntawv cog lus nyob ib puag ncig nws.
Daim duab 1: Cov qauv ntawm Methane, uas yog cov qauv yooj yim tshaj plaws ntawm Paraffin
Peb feem ntau siv lub sij hawm paraffin rau siab dua alkanes uas muaj nyob rau hauv chav tsev kub. Cov tebchaw no yog cov xim tsis muaj xim hydrocarbon sib xyaw ntawm alkanes uas peb tuaj yeem siv los ua tswm ciab, ntawv siv quav ciab, roj nplua nyeem, thiab lwm yam.
Naphthenic yog dab tsi
Naphthenic yog hais txog cov khoom uas muaj naphthene. Naphthenes yog cyclic, aliphatic hydrocarbons uas yog tsim los ntawm cov roj av. Cov mis mos ntawm naphthenes yog CnH2n Tsis tas li ntawd, cov tebchaw no muaj ib lossis ntau lub nplhaib nplhaib, uas tsuas muaj ib daim ntawv cog lus xwb. Yog li ntawd, cov no yog saturated hydrocarbon tebchaw. Peb hu lawv ua cycloparaffin.
Daim duab 2: Simple Naphthenic Compounds
Ntxiv mus, peb tuaj yeem hloov cov roj naphthenic crude rau hauv cov roj av tau yooj yim dua li hloov cov roj paraffinic crude.
Qhov txawv ntawm Paraffinic thiab Naphthenic yog dab tsi?
Qhov sib txawv tseem ceeb ntawm paraffinic thiab naphthenic yog lub sij hawm paraffinic yog hais txog cov khoom uas muaj paraffin compounds, whereas lub sij hawm naphthenic yog hais txog cov tshuaj muaj naphthene. Tsis tas li ntawd, cov qauv dav dav ntawm cov tshuaj paraffinic yog CnH2n+2 thaum cov qauv dav dav rau cov tshuaj naphthenic yog Cn H2nNtxiv mus, thaum xav txog kev hloov pauv ntawm cov roj crude rau hauv cov roj av, nws yog ib qho yooj yim los hloov cov roj naphthenic crude rau roj av; Qhov no yog qhov thim rov qab nrog cov roj paraffinic crude.
Hauv qab infographic qhia txog qhov sib txawv ntawm paraffinic thiab naphthenic.
Summary – Paraffinic vs Naphthenic
Lub sij hawm paraffinic yog hais txog cov khoom uas muaj paraffin compounds, whereas lub sij hawm naphthenic yog hais txog cov tshuaj muaj naphthene. Yog li, cov tshuaj paraffinic muaj alkanes, thaum cov tshuaj naphthenic muaj cyclic aliphatic hydrocarbons. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm paraffinic thiab naphthenic.
