Hordhac

Fumaric acid. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada ee transbutalic acid:

 

Tayada:

- Aashitada loo yaqaan 'transbutadiic acid' waa crystal aan midab lahayn ama adag oo cad oo leh dhadhan dhanaan.

-Waxay ku milmay biyaha iyo dareerayaal badan oo organic ah sida alkolada iyo ethers.

- Heerkulka sare, transbutylic acid wuu burburaa si uu u soo saaro kaarboon dioxide iyo acetone.

 

Isticmaal:

- Waxaa si weyn loogu isticmaalaa diyaarinta xabagta polyester-ka ee soo saarista alaabada sida dahaarka, balaastikada, iyo fiilooyinka.

 

Habka:

- Transbutenic acid waxaa lagu heli karaa falcelinta butene bromine iyo sodium carbonate. Habka isku-dhafka gaarka ah wuxuu ku lug leeyahay tillaabooyin badan, oo ay ku jiraan diyaarinta butene, falcelinta bromination, iyo hydrolysis alkaline.

 

Macluumaadka Badbaadada:

- Aashitada loo yaqaan 'transbutadiic acid' waa unug cuncun leh oo sababi kara cuncun iyo gubasho maqaarka iyo indhaha.

- Xidho qalabka ilaalinta shakhsi ahaaneed ee ku haboon sida galoofyada, muraayadaha, iyo dharka ilaalinta inta aad gacanta ku hayso.

- Iska ilaali in aad neefsato boodhkeeda ama uumiga, waana in ay ka hawlgashaa meel hawo fiican leh.

- Xeerarka maxalliga ah iyo nidaamyada hawlgalka ee badbaadada leh waa in la raaco marka la kaydinayo iyo la tacaalida xarunta.
