1,8-Octanediol (CAS # 629-41-4) Intangiriro

1,8-Octanediol ni ifumbire mvaruganda. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya 1,8-octandiol:

Ubwiza:
1,8-Caprylyl glycol ni amazi adafite ibara kandi abonerana uburyohe bwiza. Ifite umuvuduko muke wumuyaga hamwe nubukonje bwubushyuhe bwicyumba kandi irashobora gushonga mumazi hamwe na solge nyinshi.

Koresha:
1,8-Octanediol ifite urutonde rwibisabwa. Bikunze gukoreshwa nkibikoresho fatizo byoroshya, plasitike hamwe namavuta.

Uburyo:
1,8-Octanediol irashobora gutegurwa na okiside ya octanol. Uburyo busanzwe ni catalitike ya okiside ya octanol hamwe na ogisijeni, aho ikoreshwa rya catisale y'umuringa-chromium.

Amakuru yumutekano:
1,8-Octanediol nikintu gisanzwe gifite umutekano mubihe rusange. Guhura cyangwa guhumeka cyane kuri 1.8-caprylydiol birashobora gutera uburakari kumaso, uruhu, hamwe nubuhumekero. Mugihe ukoresha 1.8-octanediol, ibirahure birinda, gants na masike bigomba kwambara kugirango umuyaga uhumeke neza. Witondere kwirinda guhura na okiside ikomeye hamwe n’amasoko yo gutwika kugirango wirinde umuriro cyangwa guturika. Mugihe ubitse kandi ukoresha 1.8-caprylydiol, kurikiza ibipimo ngenderwaho byumutekano bijyanye.
