Intshayelelo

I-Trans-cinnamic acid yi-organic compound. Ikhona ngohlobo lweekristale ezimhlophe okanye umgubo wekristale.

 

I-Trans-cinnamic acid iqinile kwiqondo lobushushu begumbi kwaye inokunyibilika kwi-alcohols, ii-ethers kunye nezinyibilikisi ze-asidi, kwaye zinyibilika kancinane emanzini. Inevumba elimnandi elikhethekileyo.

 

I-Trans-cinnamic acid ineendlela ezahlukeneyo zokusetyenziswa.

 

Indlela yokulungiselela i-trans-cinnamic acid inokufumaneka ngokuphendula kwe-benzaldehyde kunye ne-acrylic acid. Iindlela zokulungiselela ezisetyenziswa ngokuqhelekileyo ziquka i-oxidation reaction, i-acid-catalyzed reaction kunye ne-alkaline catalytic reaction.

Ngokomzekelo, gwema ukudibanisa ngqo nolusu kunye namehlo ukuphepha ukucaphuka kunye nokuvuvukala. Xa usebenza, izixhobo ezifanelekileyo zokukhusela kufuneka zisetyenziswe, njengeiglavu zaselabhoratri, iiglasi zokukhusela, njl njl. I-Trans-cinnamic acid kufuneka igcinwe ngokufanelekileyo ukuphepha ukudibana nemithombo yokutshisa kunye nee-oxidants ukuthintela iingozi zomlilo kunye nokudubula. Ngexesha lokusetyenziswa, sebenzisa ngokuhambelana nenkqubo echanekileyo kunye neenkcukacha zokusebenza ukuqinisekisa ukhuseleko.
