Propargyl-PEG5-ọti (CAS # 87450-10-0)
Ọrọ Iṣaaju
Propynyl-tetraethylene glycol, ti a tun mọ si ọti polypropynyl, jẹ polima ti o ni awọn ẹgbẹ iṣẹ ṣiṣe propynyl ninu. Atẹle jẹ ifihan si awọn ohun-ini, awọn lilo, awọn ọna igbaradi ati alaye ailewu ti propynyl-tetrameric glycol:
Didara:
- Propynyl-tetraethylene glycol jẹ omi ti ko ni awọ si awọ ofeefee tabi ti o lagbara.
- O ni solubility ti o dara ati pe o jẹ tiotuka ninu ọpọlọpọ awọn olomi Organic ati omi.
Lo:
- O le ṣee lo bi iyipada polima, oluyipada viscosity, oluranlowo impregnation ati nipon, ati bẹbẹ lọ.
Ọna:
- Proynyl-tetraethylene glycol le ṣepọ ni ọna meji-igbesẹ, nibiti awọn ẹgbẹ iṣẹ ṣiṣe propynyl ti kọkọ ṣafihan sinu pq polyethylene glycol nipa lilo oluranlowo propynylating, atẹle nipa polymerization.
- Awọn aati Polymerization jẹ deede catalyzed nipasẹ awọn ayase irin gẹgẹbi fadaka tabi iyọ Pilatnomu.
Alaye Abo:
Propynyl-tetraethylene glycol jẹ flammable ati pe o yẹ ki o yago fun olubasọrọ pẹlu awọn ina ti o ṣii tabi awọn nkan iwọn otutu.
- Wọ awọn ibọwọ aabo ti o yẹ ati awọn oju lati yago fun olubasọrọ ara ati ifasimu nigbati o nṣiṣẹ.
- yẹ ki o wa ni ipamọ ni itura, aaye ti o ni afẹfẹ daradara ati kuro lati awọn aṣoju oxidizing.
Nigbati o ba nlo ati mimu propynyl-tetrameric glycol, awọn ilana ṣiṣe ailewu ati awọn ilana ti o yẹ yẹ ki o ṣe akiyesi.
