Polyethylene glycol 6000 imakonzedwa ndi ma polymerization amadzimadzi ethylene glycol pamatenthedwe, kuthamanga kapena kutsika pang'ono.
Polyethylene glycol 6000 (PEG-6000) English Name: macrogol 6000-992 mankhwalawa ndi osakanikirana ndi ethylene oxide ndi madzi polycondensation, mamolekyulu ndi ho (CH2CH2O) NH, pomwe n imayimira kuchuluka kwa ma oxyvinyls.
khalidwe
Izi ndizoyera phula lolimba kapena ufa wochuluka, wonunkhira pang'ono. Chogulitsacho chimasungunuka m'madzi kapena ethanol, koma sichimasungunuka mu ether. Malo ozizira a izi (Zowonjezera VI d) ndi 53 ~ 58 ℃. Viscosity tengani 25.0g ya mankhwalawa, ikani mu botolo loyesera la 100ml, onjezerani madzi kuti asungunuke ndikusungunuka pamlingo, sinthanitsani bwino, gwiritsani ntchito viscometer ya Pinker yolowa mkati mwa 1.0mm kuti mudziwe malinga ndi lamulo (Zakumapeto VI g njira 1 ). Kutulutsa kwamphamvu pa 40 ℃ ndi 10.5-16.5mm <2> / s.

Chitetezo
Zimakwiya pang'ono pakhungu ndi m'maso, ndipo ndizovuta kutengeka ndi m'mimba pambuyo poyendetsa pakamwa, ndipo kawopsedwe kali kotsika kwambiri. Jekeseni wa madzi okwanira 5% (misa) amadzimadzi a polyethylene oxide m'maso a akalulu adangopsa pang'ono. PEO sinakhudze kwenikweni kuchuluka kwa nsomba, nkhanu, Anemone, shrimp kapena algae. Utomoni wake ndi njira yothetsera madzi ndi poizoni wambiri, ndipo ndiotetezeka kugwiritsa ntchito ndi kusamalira. US Food and Drug Administration (FDA) yavomereza kugwiritsa ntchito utomoni wa polyethylene oxide amadzimadzi otsekemera popangira chakudya chapadera komanso zowonjezera zowonjezera mowa.

kuyendera
Kulemera kwakukulu kwa mankhwalawa ndi pafupifupi 12.5g, omwe amayesedwa molondola. Ikani mu botolo lokhala ndi 250ml lokhala ndi cholembera, onjezerani 25ml pyridine, itenthetseni kuti isungunuke, ndikuziziritsa. Malinga ndi njira ya polyethylene glycol 400, kuyambira pa "pyridine solution yowonjezedwa ndi phthalic anhydride ndendende", kuchuluka kwama molekyulu kuyenera kukhala 5400-7800. Acidity, momveka bwino ndi mtundu wa yankho, ndi zotsalira pazoyatsira ziyenera kuyang'aniridwa molingana ndi njira yofotokozedwera polyethylene glycol 400.
