Nhanganyaya

Trans-cinnamic acid inhengo yehupenyu. Inowanikwa muchimiro chekristaro chena kana crystalline poda.

Trans-cinnamic acid yakasimba pakupisa kwekamuri uye inogona kunyungudutswa mudoro, ether uye zvinonyungudutsa asidhi, uye inonyungudika zvishoma mumvura. Iine kunhuhwirira kwakakosha.

Trans-cinnamic acid ine zvakasiyana-siyana zvekushandisa.

Nzira yekugadzirira ye trans-cinnamic acid inogona kuwanikwa nekuita kwe benzaldehyde uye acrylic acid. Inowanzo shandiswa nzira dzekugadzirira dzinosanganisira oxidation reaction, acid-catalyzed reaction uye alkaline catalytic reaction.

Semuenzaniso, dzivisa kutarisana zvakananga neganda uye maziso kuti udzivise kutsamwa uye kuzvimba. Paunenge uchishanda, midziyo yekudzivirira yakakodzera inofanirwa kushandiswa, senge magirovhosi emurabhoritari, magirazi ekudzivirira, nezvimwewo Trans-cinnamic acid inofanirwa kuchengetwa nemazvo kuti isasangana nezvinobatidza moto uye maoxidants kudzivirira njodzi dzemoto nekuputika. Panguva yekushandiswa, shanda zvinoenderana nemaitiro chaiwo uye maitiro ekushanda kuti uve nechokwadi chekuchengetedza.
