Taw qhia

Trans-cinnamic acid yog cov organic compound. Nws muaj nyob rau hauv daim ntawv ntawm dawb crystals los yog crystalline hmoov.

Trans-cinnamic acid yog khoom nyob rau hauv chav tsev kub thiab yuav yaj nyob rau hauv cawv, ethers thiab acid solvents, thiab me ntsis soluble nyob rau hauv dej. Nws muaj ib tug tshwj xeeb aromatic aroma.

Trans-cinnamic acid muaj ntau yam kev siv.

Txoj kev npaj ntawm trans-cinnamic acid tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm benzaldehyde thiab acrylic acid. Feem ntau siv cov kev npaj muaj xws li oxidation cov tshuaj tiv thaiv, acid-catalyzed cov tshuaj tiv thaiv thiab alkaline catalytic cov tshuaj tiv thaiv.

Piv txwv li, tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag kom tsis txhob khaus thiab o. Thaum ua haujlwm, cov cuab yeej tiv thaiv tsim nyog yuav tsum tau siv, xws li cov hnab looj tes hauv chav kuaj, tsom iav tiv thaiv, thiab lwm yam. Trans-cinnamic acid yuav tsum tau muab khaws cia kom zoo kom tsis txhob muaj kev sib cuag nrog cov khoom siv hluav taws xob thiab cov oxidants los tiv thaiv hluav taws thiab tawg. Thaum siv, ua haujlwm raws li cov txheej txheem raug thiab kev ua haujlwm tshwj xeeb kom muaj kev nyab xeeb.
