Hordhac

Trans-cinnamic acid waa iskudhis organic ah. Waxay u jirtaa qaab kiristaalo cad ama budo crystalline ah.

Trans-cinnamic acid waa ku adag tahay heerkulka qolka waxaana lagu milmi karaa aalkolada, ethers iyo dareerayaasha aashitada, iyo in yar oo biyo ku milmi kara. Waxay leedahay udgoon gaar ah.

Trans-cinnamic acid waxay leedahay adeegsiyaal kala duwan.

Habka diyaarinta ee trans-cinnamic acid waxaa lagu heli karaa falcelinta benzaldehyde iyo acrylic acid. Hababka diyaarinta ee sida caadiga ah loo isticmaalo waxaa ka mid ah falcelinta oksaydheynta, falcelinta acid-catalyzed iyo falcelinta catalytic alkaline.

Tusaale ahaan, iska ilaali taabashada tooska ah ee maqaarka iyo indhaha si aad uga fogaato xanaaq iyo barar. Marka la shaqaynayo, waa in la isticmaalaa qalab ilaalin ku haboon, sida galoofyada shaybaadhka, muraayadaha difaaca, iwm Inta lagu jiro isticmaalka, u shaqee si waafaqsan nidaamka saxda ah iyo qeexida hawlgalka si loo xaqiijiyo badbaadada.
