Cinnamic acid ke selelekela sa tlhahiso ea palo e kholo ea limela, ho kenyelletsa lignin, tannins, flavonoids, li-pigments, likarolo tse ngata tsa tatso ea linoko le li-alkaloids tse fapaneng, joalo ka morphine le colchicine.

Tšebeliso:

Cinnamic acid ke ntho ea bohlokoa hobane e sebelisoa haholo indastering ea litlolo, lijo, lifoto, polymer le meriana, hammoho le lithuto tsa bongaka le tsa chefo.Ho fihlela joale, mekhoa e mengata e tlalehiloe bakeng sa qeto ea eona, e kang titrimetry, differential-pulse polarography, spectrophotometry, mass spectrometry, HPLC, electrokinetic capillary chromatography, capillary electrophoresis, chromatography ea khase le chromatography ea metsi.Leha ho le joalo, ho na le mathata a mangata holim'a mekhoa ena, joalo ka nako e telele ea karabo, tšebeliso ea reagent, ts'ebetso e rarahaneng, joalo-joalo.

1. Litlolo le monko o monate

E ka sebelisoa e le motsoako o nkhang hamonate ka har'a sesepa, li-shampoo, phofo ea ho hlatsoa, ​​​​le litlolo tsa letsatsi le letsatsi.Cinnamonic acid e sebelisoa tatsong ea apole, tatso ea cherry, tatso ea litholoana le monko o monate oa lipalesa.E na le phello ea ho thibela ho thehoa ha black tyrosinase, e na le phello e itseng e sireletsang mahlaseling a ultraviolet, e ka etsa hore matheba a sootho a be bobebe kapa a nyamele, 'me ke e' ngoe ea metsoako ea bohlokoa ho setlolo se tsoetseng pele sa letsatsi.Cinnamic acid ka boeona ke mofuta oa linoko, tse nang le phello e ntle ea ho boloka monko.Hangata e sebelisoa e le thepa e tala bakeng sa monko o monate, e leng se etsang hore monko oa monko o monate o be o sa tsitsang.

2. Indasteri ea meriana

Ka indasteri ea meriana, e ka sebelisoa e le lithethefatsi tsa bohlokoa bakeng sa ho qaptjoa le ho phekola lefu la pelo.E ka sebelisoa e le pelo-to-pelo le pelo-to-pelo, hammoho le synthetic chlorpheniric acid le cinnamyl piperazine.E ka sebelisoa ho etsa "Xin Kean", anesthetic ea sebakeng seo, fungicide, hemostasis.Meriana, joalo-joalo Chlorobenamide le cinnamyl piperazine li ka boela tsa etsoa hore li sebelisoe e le setlolo sa lesapo la mokokotlo le moemeli oa antispasmodic.Haholo-holo e sebelisoa bakeng sa thrombosis ea boko, lefu la cerebral arteriosclerosis, coronary artery cirrhosis le mafu a mang.E na le phello e kholo ea ho thibela ho ata ha lisele tsa matšoafo adenocarcinoma.

3. Organic synthesis

Mabapi le motsoako oa lik'hemik'hale tsa organic, cinnamic acid e ka sebelisoa e le ntho e tsitsitseng ea ho lokolla maqephe a galvanized, stabilizer ea mocheso bakeng sa polyvinyl chloride, crosslinker bakeng sa polyurethane, retardant ea mollo bakeng sa hydantoin le polycaprolactam, le reagent ea ho hlahloba lik'hemik'hale.Hape ke reagent bakeng sa ho khetholla karohano ea uranium le vanadium;hape ke thepa ea bohlokoa ka ho fetisisa ea maiketsetso bakeng sa li-resin tsa mofuta o mobe.The main synthetic lauric acid ester, polyvinyl alcohol cinnamate, ethyl ethoxy cinnamate le epoxy resin e nang le pendant cinnamate.E sebelisoa ka har'a li-plastiki, e ka sebelisoa e le mocheso o tsitsitseng bakeng sa PVC, anti-mold le deodorant bakeng sa sterilizing, hape e ka kenngoa ka rabara le foam ho etsa lieta le li-insoles.E ka sebelisoa hape bakeng sa k'hothone le likhoele tse fapaneng tsa maiketsetso, letlalo le pente.Thibela hlobo ho lihlahisoa tse kang polishe ea lieta le meseme ea joang.
