Wb txais tos Dicyclopentadiene los hais lus txog lawv tsev neeg.
Dicyclopentadiene (DCPD) Kev Taw Qhia Tus Kheej
Nyob zoo xyoo tshiab, kuv lub npe yog Dicyclopentadiene, kuv lub npe menyuam yaus yog DCPD.Kuv tseem hu ua Dicyclopentadiene dimer.Kuv yog cov kua tsis muaj xim tsis muaj xim thiab yooj yim rau crystallize, nrog camphor tsw.Txhua tus hauv DCPD tsev neeg muaj cov yam ntxwv zoo sib xws, thiab qhov ntawd yog kev ua haujlwm hauv chemistry.Koj puas paub vim li cas?
Qhov no yog vim peb cov molecule muaj ntau yam unsaturated ob daim ntawv cog lus.Vim qhov no feature, peb yog heev reactive thiab nquag mus rau txhua yam ntawm polymerization tshuaj.Tom qab ntawd ntau yam derivatives ntawm Dicyclopentadiene (DCPD) tshwm sim.
Sawv cev ntawm kuv tsev neeg Dicyclopentadiene (DCPD), Kuv thov kom koj nyob zoo Xyoo Tshiab.
Dicyclopentadiene (DCPD) Keeb Kwm Thiab Yug
Peb tau tshawb pom raws li C10H12 hydrocarbon ntawm cov khoom ntawm pyrolysis ntawm phenol los ntawm Henry Roscoe, tab sis nws tsuas yog xav tias peb (DCPD) yog ib qho dimer ntawm qee qhov C5H6 hydrocarbon es tsis txhob qhia peb cov qauv.Tom qab ntau xyoo, cov qauv ntawm peb cov dicyclopentadiene (DCPD) tau xav tias muaj lub nplhaib cyclobutane raws li kev sib xyaw ntawm ob lub subunits thiab txiav tawm hauv 1931 los ntawm kev siv zog ntawm Alder thiab cov neeg ua haujlwm.
Peb tuaj ntawm thee tar thaum ntxov thaum cov neeg hauv tsev neeg tsawg dua li tam sim no.Nrog rau txoj kev loj hlob ntawm kev lag luam roj, feem ntau ntawm cov tswv cuab hauv DCPD tsev neeg yug los ntawm C5 feem, cov khoom los ntawm cov roj av tawg mus rau ethylene.Hauv cov txheej txheem no, cov khoom lag luam los ntawm cov khoom lag luam muaj ntau thiab nyuaj, ntawm lawv, isoprene (IP), cyclopentadiene (CPD) thiab m-pentadiene (PD) txhua tus muaj txiaj ntsig zoo thiab cov ntsiab lus siab, uas suav txog li 50% ntawm C5 feem.
Dicyclopentadiene (DCPD) yog tsim los ntawm dimerization ntawm cyclopentadiene (CPD) los ntawm Diels-Alder cov tshuaj tiv thaiv hauv kev daws.Thawj kauj ruam ua cua sov yog siv los copolymerize cyclopentadiene (CPD) rau hauv dicyclopentadiene (DCPD), dicyclopentadiene (DCPD) yog cais los ntawm lwm yam teeb pom kev zoo (qhov kub kub <45 ° C) los ntawm distillation, thiab tom qab ntawd lwm yam uas yuav tsum tau muaj, monocyclopentadiene yog cais los ntawm kuab tshuaj extraction.Txoj kev no siv qhov zoo ntawm cov yam ntxwv uas cyclopentadiene (CPD) yooj yim dua rau dimerize dua li lwm qhov C5 feem.Thiab tom qab ntawd cov dicyclopentadiene (DCPD) tau sib cais los ntawm C5 feem los ntawm kev distillation vim tias peb cov ntsiab lus kub kub yog siab dua li ntawm lwm cov C5 hydrocarbons.
Dicyclopentadiene (DCPD) Cov Lus Qhia Ua Haujlwm
Peb (dicyclopentadiene / DCPD) tau koom nrog hauv cov organic chemical raw khoom thiab hlau polymer cov ntaub ntawv.Lub lim tiam dhau los no, kuv nyuam qhuav muab cov kev qhia txog kev ua haujlwm rau cov neeg kawm tiav uas yuav nkag mus rau hauv kev ua lag luam.Cov menyuam yaus ntawm DCPD tsev neeg muaj ntau txoj haujlwm xaiv.Feem ntau ntawm lawv yuav ua haujlwm hauv chaw muag tshuaj, tshuaj tua kab, hluavtaws resins, txuj lom, hluavtaws roj hmab thiab lwm yam.Lawv tuaj yeem hloov mus rau adamantane, 2-Chloro-5-chloromethylpyridine, metallocene, glutaraldehyde, carbamate, epoxy resin curing agent, nplaim hluav taws, dicyclopentadiene chloride (secticide), thiab lwm yam. Qhov kev xaiv no yuav hloov lawv cov tsos thiab cov yam ntxwv.
Cov neeg tau pom tias hloov kho hydrocarbon resins tau nce reactivity nyob rau hauv copolymerizations nrog qhuav roj, thiab tsim cov xim resins nrog txhim kho tus nqi ziab, gloss, thiab hardness.yog li DCPD muaj lwm txoj kev xaiv.Lawv tuaj yeem koom nrog hloov kho hydrocarbon resins tuam txhab.Thaum lawv ua haujlwm hauv daim teb no, lawv yuav ua lub luag haujlwm tseem ceeb hauv inks, adhesives thiab xim.
Dicyclopentadiene (DCPD) yav tom ntej
Peb yog ib tsev neeg uas tsis tuaj yeem tsis quav ntsej txog kev muaj peev xwm ntawm peb cov peev txheej nyiaj txiag thiab kev cia siab rau kev loj hlob.Cov neeg thoob ntiaj teb tau tshawb fawb ntau ntawm DCPD thiab sau cov ntawv.Peb qhov xwm txheej ua haujlwm tau zoo dua thiab kub dua, thiab peb tsis tuaj yeem sib cais ntawm tib neeg lub neej.
