Intangiriro

Acide Fumaric. Ibikurikira ni intangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya acide transbutalic:

 

Ubwiza:

- Acide ya Transbutadiic ni kirisiti itagira ibara cyangwa ibara ryera rifite uburyohe busharira.

- Irashobora gushonga mumazi hamwe numuti mwinshi kama nka alcool na ethers.

- Ku bushyuhe bwinshi, aside transbutylic iracika kugirango itange karuboni ya dioxyde na acetone.

 

Koresha:

- Ikoreshwa cyane mugutegura ibisigazwa bya polyester mugukora ibicuruzwa nka coatings, plastike, na fibre.

 

Uburyo:

- Acide Transbutenedic irashobora kuboneka mugukora reaction ya butome na karubone ya sodium. Uburyo bwihariye bwa synthesis ikubiyemo intambwe nyinshi, harimo gutegura butene, reaction ya bromination, na hydrolysis ya alkaline.

 

Amakuru yumutekano:

- Acide Transbutadiic nuruvange rushobora gutera uburakari no gutwikwa uhuye nuruhu namaso.

- Kwambara ibikoresho bikwiye byo kurinda nka gants, ibirahure, n imyenda ikingira mugihe ukora.

- Irinde guhumeka umukungugu cyangwa imyuka kandi ugomba gukorera ahantu hafite umwuka mwiza.

- Amabwiriza yinzego zibanze hamwe nuburyo bukwiye bwo gukora bigomba gukurikizwa mugihe cyo kubika no gutunganya uruganda.
