Cinnamic acid ndi organic pawiri ndi formula C6H5CH=CHCOOH.Ndi gulu loyera la crystalline lomwe limasungunuka pang'ono m'madzi, ndipo limasungunuka momasuka muzosungunulira zambiri za organic.Imadziwika kuti ndi unsaturated carboxylic acid, imapezeka mwachilengedwe muzomera zingapo.Imapezeka ngati cis ndi trans isomer, ngakhale yomalizayo ndiyofala kwambiri.

Cinnamic acid ndi chapakati chapakatikati mu biosynthesis ya zinthu zambiri zachilengedwe monga lignolsto lignin ndi lignocellulose, flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, ndi phenylpropanoids.Zake biosynthesis amachitidwa ndi zochita za enzyme phenylalanine ammonia-lyase (PAL) pa phenylalanine.

Cinnamic acid ndi kalambulabwalo wa kaphatikizidwe wa zinthu zambiri zomera, kuphatikizapo lignin, tannins, flavonoids, inki, ambiri a kukoma zigawo zikuluzikulu za zonunkhira, ndi alkaloids zosiyanasiyana, monga morphine ndi colchicine.

Kagwiritsidwe:

Cinnamic acid ndi chinthu chofunikira chifukwa imagwiritsidwa ntchito kwambiri mumafuta onunkhira, chakudya, zithunzi, ma polima ndi mafakitale opanga mankhwala, komanso maphunziro azachipatala komanso oopsa.Mpaka pano, njira zambiri zadziwika chifukwa cha kutsimikiza kwake, monga titrimetry, differential-pulse polarography, spectrophotometry, mass spectrometry, HPLC, electrokinetic capillary chromatography, capillary electrophoresis, gas chromatography ndi liquid chromatography.Komabe, pali zovuta zambiri panjirazi, monga kuyankha nthawi yayitali, kugwiritsa ntchito reagent, ntchito yovuta, ndi zina zambiri.

1. Zonunkhira ndi zonunkhira

Itha kugwiritsidwa ntchito ngati chosakaniza chonunkhira mu sopo, ma shampoos, ufa wochapira, ndi zodzoladzola zatsiku ndi tsiku.Cinnamonic acid imagwiritsidwa ntchito mu kukoma kwa apulo, kukoma kwa chitumbuwa, kukoma kwa zipatso, ndi kununkhira kwamaluwa.Zimakhala ndi zotsatira zolepheretsa mapangidwe a black tyrosinase, zimakhala ndi zotsatira zotetezera pa cheza cha ultraviolet, zimatha kupangitsa mawanga a bulauni kukhala opepuka kapena ngakhale kutha, ndipo ndi chimodzi mwa zinthu zofunika kwambiri pazitsulo zoteteza dzuwa.Cinnamic acid palokha ndi mtundu wa zonunkhira, zomwe zimakhala ndi fungo labwino losunga fungo.Nthawi zambiri amagwiritsidwa ntchito ngati zinthu zopangira zonunkhira, zomwe zimapangitsa kuti fungo la fungo lalikulu likhale losasunthika.

2. Makampani opanga mankhwala

M'makampani opanga mankhwala, angagwiritsidwe ntchito ngati mankhwala ofunikira pakupanga ndi kuchiza matenda amtima.Itha kugwiritsidwa ntchito ngati pamtima pamtima komanso pamtima, komanso kupanga chlorpheniric acid ndi cinnamyl piperazine.Itha kugwiritsidwa ntchito kupanga "Xin Kean", mankhwala am'deralo, fungicide, hemostasis.Mankhwala, etc. Chlorobenamide ndi cinnamyl piperazine amathanso kupangidwa kuti agwiritsidwe ntchito ngati fupa la msana komanso antispasmodic wothandizira.Makamaka ntchito ubongo thrombosis, ubongo arteriosclerosis, coronary mtsempha wamagazi enaake matenda enaake.Ili ndi cholepheretsa chachikulu pakukula kwa maselo am'mapapo adenocarcinoma.

3. Organic kaphatikizidwe

Pankhani ya organic chemical synthesis, cinnamic acid ingagwiritsidwe ntchito ngati chotulutsa chokhazikika pamapepala opaka malata, chowongolera kutentha kwa polyvinyl chloride, crosslinker for polyurethane, retardant lawi la hydantoin ndi polycaprolactam, ndi reagent yowunikira mankhwala.Komanso ndi reagent yodziwira kulekanitsa kwa uranium ndi vanadium;Ndiwonso chinthu chofunikira kwambiri chopangira ma resin amtundu wa photosensitive resins.The main synthetic lauric acid ester, polyvinyl alcohol cinnamate, ethyl ethoxy cinnamate ndi epoxy resin yokhala ndi pendant cinnamate.Imagwiritsidwa ntchito mu mapulasitiki, imatha kugwiritsidwa ntchito ngati chokhazikika cha kutentha kwa PVC, anti-mold ndi deodorant pochotsa chofewetsa, komanso itha kuwonjezeredwa mu mphira ndi thovu kuti mupange nsapato zoziziritsa kukhosi ndi insoles.Itha kugwiritsidwanso ntchito pa thonje ndi ulusi wopangira zosiyanasiyana, zikopa ndi utoto.Pewani mildew muzinthu monga polishi wa nsapato ndi mateti a udzu.
