Propargyl-PEG5-alcohol (CAS # 87450-10-0)
Taw qhia
Propynyl-tetraethylene glycol, tseem hu ua polypropynyl cawv, yog ib qho polymer uas muaj propynyl functional pawg. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm propynyl-tetrameric glycol:
Zoo:
- Propynyl-tetraethylene glycol yog cov xim tsis muaj xim rau yellowish kua lossis khoom.
- Nws muaj solubility zoo thiab soluble nyob rau hauv feem ntau cov organic solvents thiab dej.
Siv:
- Nws tuaj yeem siv los ua polymer hloov pauv, viscosity hloov pauv, tus neeg sawv cev impregnation thiab thickener, thiab lwm yam.
Txoj kev:
- Proynyl-tetraethylene glycol tuaj yeem ua ke nyob rau hauv ob-kauj ruam txheej txheem, qhov twg propynyl kev ua haujlwm pab pawg thawj zaug tau nkag mus rau hauv cov saw hlau polyethylene glycol siv tus neeg sawv cev propynylating, ua raws li polymerization.
- Cov tshuaj tiv thaiv Polymerization feem ntau yog catalyzed los ntawm hlau catalysts xws li nyiaj los yog platinum ntsev.
Cov ntaub ntawv kev nyab xeeb:
- Propynyl-tetraethylene glycol yog flammable thiab yuav tsum tau zam los ntawm kev sib cuag nrog cov nplaim taws qhib lossis cov khoom kub kub.
- Hnav cov hnab looj tes tiv thaiv thiab qhov muag kom tsis txhob sib cuag ntawm daim tawv nqaij thiab nqus tau pa thaum ua haujlwm.
- Yuav tsum khaws cia rau hauv qhov chaw txias, qhov cua zoo thiab kom deb ntawm cov neeg ua haujlwm oxidizing.
- Thaum siv thiab tuav propynyl-tetrameric glycol, yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb thiab cov kev cai cuam tshuam.
