Intangiriro
Acide Dimethyl azelaic (izwi kandi nka Dioctyl adipate, DOA) ni ibinyabuzima bisanzwe. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:
Ubwiza:
- Kugaragara: Ibara ritagira ibara ry'umuhondo
- Gukemura: gushonga mumashanyarazi kama, gushonga gato mumazi
- Indangantego yangiritse: hafi. 1.443-1.449
Koresha:
- Dimethyl azelarate ikoreshwa cyane cyane nka plastiki, ifite plastike nziza kandi irwanya ubukonje, kandi irashobora kongera ubworoherane nubukonje bwa plastiki.
- Bikunze gukoreshwa mugukora plastike ya polyvinyl chloride (PVC), reberi yubukorikori, ibisigazwa bya sintetike, nibindi, kugirango bitezimbere plastike n'imbaraga.
- Dimethyl azelaate irashobora kandi gukoreshwa nka lubricant, yoroshye na antifreeze, mubindi.
Uburyo:
Acide Dimethyl azelaic isanzwe itegurwa na esterification reaction kuburyo bukurikira:
1. Kora nonanediol hamwe na acide adipic.
2. Ongeramo ibintu bya esterifike, nka acide sulfurike, nkibisubizo bya esterification reaction.
3. Igisubizo gikozwe mubushyuhe bukwiye hamwe nubushyuhe bwo kubyara dimethyl azelaate.
4. Ibicuruzwa byongeye kwezwa no kubura umwuma, kurigata hamwe nizindi ntambwe.
Amakuru yumutekano:
- Acide Dimethyl azelaic igomba kurindwa mugihe gikoreshwa kandi ikirinda guhura nuruhu namaso.
- Kwambara ibikoresho bikingira, harimo kurinda ubuhumekero na gants zo gukingira, niba bikoreshejwe.
- Hagomba kwitonderwa ibidukikije bihumeka neza mugihe cyo gukora kugirango wirinde guhumeka cyangwa gufatwa nimpanuka.
- Mugihe cyo kubika no gutwara, birakenewe kwirinda guhura na okiside, acide nibindi bintu kugirango twirinde impanuka.
