Dicyclopentadiene (DCPD)'s Self-sumo
Goredzva rakanaka, zita rangu ndinonzi Dicyclopentadiene, zita rangu remadunhurirwa ndiDCPD.Ini zvakare ndinonzi Dicyclopentadiene dimer.Ini ndiri mvura isina ruvara yakajeka uye iri nyore kupenya, ine camphor inonhuhwirira.Munhu wese mumhuri yeDCPD ane hunhu hwakafanana, uye ndiko kuita mukemesitiri.Unoziva here kuti nei?
Izvi zvinodaro nekuti molekuru yedu ine akawanda unsaturated maviri mabhondi.Nekuda kwechinhu ichi, isu tinoshanda zvakanyanya uye tinowanzo kune ese marudzi epolymerization maitiro.Zvadaro zvakasiyana-siyana zvinobva kune Dicyclopentadiene (DCPD) zvakaonekwa.
Ndakamiririra mhuri yangu yeDicyclopentadiene (DCPD), ndinokushuvirai mese Goredzva rakanaka.
Dicyclopentadiene(DCPD)'s History And Birth
Isu takaonekwa seC10H12 hydrocarbon pakati pezvigadzirwa zve pyrolysis ye phenol naHenry Roscoe, asi akangofungidzira nemazvo kuti isu (DCPD) taive dimer yeimwe C5H6 hydrocarbon pane kuziva chimiro chedu.Mushure memakore akawanda, chimiro che dicyclopentadiene (DCPD) yedu yaifungidzirwa kuti inoratidzira cyclobutane mhete semusanganiswa pakati pezvikamu zviviri uye yakatorwa muna 1931 kuburikidza nekuedza kwaAlder uye waanoshanda naye.
Takabva kutara yemarasha pakutanga apo mitezo yemhuri yakanga iri shoma zvikuru kupfuura zvino.Nekuvandudzwa kweindasitiri yemafuta, vazhinji venhengo dzemhuri yeDCPD dzakazvarwa kubva muchikamu cheC5, iyo-yakagadzirwa petroleum inoputika kune ethylene.Muchiitiko ichi, ne-products yakawanda uye yakaoma, pakati pavo, isoprene (IP), cyclopentadiene (CPD) uye m-pentadiene (PD) vose vane kukosha kwekushandiswa kwepamusoro uye zvinyorwa zvepamusoro, izvo zvinotora anenge 50% yeC5 chikamu.
Dicyclopentadiene (DCPD) inoumbwa ne dimerization ye cyclopentadiene (CPD) neDiels-Alder reaction in solution.Nhanho yekutanga yekudziya inoshandiswa kucopolymerize cyclopentadiene(CPD) kuita dicyclopentadiene(DCPD), dicyclopentadiene(DCPD) inoparadzaniswa kubva kune zvimwe zvinhu zvinopenya (boiling point <45°C) ne distillation, uyezve mamwe anodiwa dienes, monocyclopentadiene anoparadzaniswa ne solvent extract.Iyi nzira inotora mukana wehunhu hwekuti cyclopentadiene(CPD) iri nyore kuita dimerize pane zvimwe zvikamu zveC5.Uye ipapo dicyclopentadiene (DCPD) inoparadzaniswa kubva kune zvikamu zveC5 ne distillation nokuti nzvimbo yedu yekubikira yakanyanya kudarika yeimwe C5 hydrocarbons.
Dicyclopentadiene (DCPD)'s Employment Directions
Isu (dicyclopentadiene / DCPD) tiri kuita zvekutanga organic makemikari mbishi zvinhu uye simbi polymer zvinhu.Svondo rapfuura, ndichangopa makosi ekutungamira mabasa kune vakapedza zvidzidzo vaizopinda mumusika wemabasa.Vana vemhuri yeDCPD vane sarudzo dzakawanda dzebasa.Vazhinji vacho vanozoshanda mumishonga yemishonga, mishonga yezvipembenene, masynthetic resin, zvinonhuwira, synthetic rubber nemimwe minda.Vanogona kuchinjwa kuva adamantane, 2-Chloro-5-chloromethylpyridine, metallocene, glutaraldehyde, carbamate, epoxy resin kuporesa agent, flame retardant, dicyclopentadiene chloride (insecticide), etc. Ichi chisarudzo chichashandura chitarisiko chavo uye maitiro.
Vanhu vakaona kuti yakagadziridzwa hydrocarbon resins yakawedzera reactivity mu copolymerizations nemafuta ekuomesa, uye inogadzira mapendi ependi ane yakagadziridzwa kuomesa mwero, kupenya, uye kuoma.saka maDCPD ane imwe sarudzo.Ivo vanogona kujoinha yakagadziridzwa hydrocarbon resins kambani.Pavanenge vachishanda mundima iyi, vachaita basa guru muinki, zvinonamatira uye pendi.
Dicyclopentadiene (DCPD)'s Ramangwana
Isu tiri mhuri isingagone kufuratirwa isu tine kukosha kwedu kwehupfumi uye tarisiro yakafara yebudiriro.Vanhu pasi rese vanoita tsvakiridzo yakawanda paDCPD uye vanonyora zvinyorwa.Mamiriro edu emabasa ari kuita zvirinani uye achipisa, uye hatisi kuparadzaniswa nehupenyu hwevanhu.
