Inzobere mu gukora inzoga za propargyl, 1,4 butynediol na 3-chloropropyne

  • Gukoresha butanediol mu kwisiga

    Gukoresha butanediol mu kwisiga

    Butanediol, cyane cyane acetylene na formaldehyde nkibikoresho fatizo.Ikoreshwa nk'iyagura urunigi mu gukora polybutylene terephthalate na polyurethane, kandi nk'ibikoresho by'ibanze bya tetrahydrofuran, γ-butyrolactone, ubuvuzi na synthesis.Kuberako polybutylene terephthalate ari ubwoko bwa polyester ifite imitungo myiza, ibyifuzo bya plastiki yubuhanga biriyongera vuba.

  • Imiti ya laboratoire ifite ubumara bukabije - inzoga ya propargyl

    Imiti ya laboratoire ifite ubumara bukabije - inzoga ya propargyl

    Inzoga ya Propargyl, amata ya molekuline C3H4O, uburemere bwa molekile 56. Amazi adafite amabara meza, ahindagurika afite impumuro mbi, uburozi, kurakara cyane kuruhu n'amaso.Hagati mungingo ngengabihe.Ahanini ikoreshwa muguhuza imiti ya antibacterial na anti-inflammatory sulfadiazine;Nyuma ya hydrogène igice, inzoga ya propylene irashobora kubyara resin, hanyuma nyuma ya hydrogenation yuzuye, n-propanol irashobora gukoreshwa nkibikoresho fatizo byimiti igabanya ubukana bwitwa ethambutol, nibindi bicuruzwa bivura imiti na farumasi.Irashobora kubuza aside ibyuma, umuringa na nikel hamwe nibindi byuma byangirika, bikoreshwa mugukuraho ingese.Byakoreshejwe cyane mugukuramo amavuta.Irashobora kandi gukoreshwa nka solvent, stabilisateur ya hydrocarbone ya chlorine, ibyatsi byica udukoko.Irashobora gukoreshwa mugukora acide acrylic, acrolein, 2-aminopyrimidine, γ-picauline, vitamine A, stabilisateur, inhibitori ya ruswa nibindi.

    Andi mazina: inzoga ya propargyl, 2-propargyl - 1-inzoga, inzoga 2-propargyl, inzoga ya propargyl acetylene methanol.

  • Propargyl izahindura polymerize kandi iturike

    Propargyl izahindura polymerize kandi iturike

    Inzira yambere ishingiye kuri alcool ya propargyl nkibishishwa, KOH nkibishingwe, gushyushya reaction kugirango ubone intego.Igisubizo kidafite imiterere yo kugabanuka kizaba umwanda muke, reaction irasukuye.

    Urebye ibishobora guterwa na polymerisime no guturika guturika kwa alkynes, Laboratwari ya Hazard Evaluation ya Amgen (HEL) yinjiye kugira ngo isuzume umutekano kandi ifashe mu buryo bunoze mbere yo gupima litiro 2 za reaction.

    Ikizamini cya DSC cyerekana ko reaction itangira kubora kuri 100 ° C ikarekura ingufu za 3667 J / g, mugihe inzoga ya propargyl na KOH hamwe, nubwo ingufu zigabanuka zikagera kuri 2433 J / g, ariko ubushyuhe bwo kubora nabwo bukamanuka kuri 85 ° C, kandi ubushyuhe bwibikorwa buri hafi ya 60 ° C, ibyago byumutekano ni byinshi.

  • 1,4-butanediol (BDO) no gutegura ibinyabuzima byangiza PBAT

    1,4-butanediol (BDO) no gutegura ibinyabuzima byangiza PBAT

    1, 4-butanediol (BDO);PBAT ni plastiki ya termoplastique ya biodegradable plastike, ikaba ikora kopolymer ya butanediol adipate na butanediol terephthalate.Ifite ibiranga PBA (polyadipate-1, 4-butanediol ester diol) na PBT (polybutanediol terephthalate).Ifite ihindagurika ryiza no kurambura kuruhuka, kimwe no kurwanya ubushyuhe bwiza no gukora ingaruka.Byongeye kandi, ifite ibinyabuzima byiza cyane kandi ni kimwe mu bikoresho bizwi cyane mu binyabuzima mu bushakashatsi bwa plastiki y’ibinyabuzima ndetse no gukoresha neza isoko.

  • Umusaruro wa 1, 4-butanediol (BDO) hakoreshejwe uburyo bwa anhydride ya kigabo

    Umusaruro wa 1, 4-butanediol (BDO) hakoreshejwe uburyo bwa anhydride ya kigabo

    Hariho inzira ebyiri zingenzi zo gukora BDO na anhydride ya kigabo.Imwe muriyo ni inzira ya hydrogenation itaziguye ya anhydride yumugabo yakozwe na Mitsubishi Petrochemical na Mitsubishi Chemical mu Buyapani mu myaka ya za 70, irangwa no gukora icyarimwe icyarimwe cya BDO, THF na GBL mugikorwa cya hydrogenation ya anhydride yumugabo.Ibicuruzwa byahimbwe bitandukanye birashobora kuboneka muguhindura imikorere.Ibindi ni inzira ya gaz esterification hydrogenation ya anhydride yumugabo yakozwe na Sosiyete ya UCC hamwe na Davey Process Technology Company mu Bwongereza, ikaba yaratejwe imbere n’ikoranabuhanga rito rya karubone.Muri 1988, kongera gusuzuma isuzuma ryibikorwa byarangiye kandi hasabwa igishushanyo mbonera.Mu 1989, IKORANABUHANGA ryimuriwe muri DongSANG CHEMICAL COMPANY YO MURI Koreya NA DONGGU CHIMICAL YUbuyapani KUBAKA 20.000-TON / umwaka 1, 4-BUtanEDIOL INGANDA Y’inganda.
