Cinnamic acid yog ib qho organic compound nrog formula C6H5CH = CHCOOH.Nws yog dawb crystalline compound uas yog me ntsis soluble nyob rau hauv dej, thiab dawb soluble nyob rau hauv ntau cov organic solvents.Muab faib ua ib qho unsaturated carboxylic acid, nws tshwm sim nyob rau hauv ib tug xov tooj ntawm cov nroj tsuag.Nws tshwm sim raws li ob qho tib si cis thiab trans isomer, txawm hais tias tom kawg yog ntau dua.

Cinnamic acid yog lub hauv paus nruab nrab hauv biosynthesis ntawm myriad natural khoom xws li lignolsto lignin thiab lignocellulose, flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, thiab phenylpropanoids.Nws biosynthesis yog ua los ntawm kev ua ntawm enzyme phenylalanine ammonia-lyase (PAL) ntawm phenylalanine.

Cinnamic acid yog ib tug precursor rau synthesis ntawm ib tug loj tus naj npawb ntawm cov nroj tsuag tshuaj, xws li lignin, tannins, flavonoids, pigments, ntau yam ntawm cov tsw ntawm txuj lom, thiab ntau yam alkaloids, xws li morphine thiab colchicine.

Kev siv:

Cinnamic acid yog ib yam khoom tseem ceeb vim nws tau siv dav hauv cov tshuaj tsw qab, khoom noj khoom haus, kev yees duab, polymer thiab kev lag luam tshuaj, nrog rau kev tshawb fawb soj ntsuam thiab tshuaj toxicological.Txog tam sim no, ntau txoj hauv kev tau tshaj tawm rau nws qhov kev txiav txim siab, xws li titrimetry, qhov sib txawv-pulse polarography, spectrophotometric, huab hwm coj spectrometry, HPLC, electrokinetic capillary chromatography, capillary electrophoresis, roj chromatography thiab kua chromatography.Txawm li cas los xij, muaj ntau qhov tsis zoo ntawm cov txheej txheem no, xws li lub sijhawm teb ntev, kev siv reagent, kev ua haujlwm nyuaj, thiab lwm yam.

1. Flavors thiab fragrances

Nws tuaj yeem siv los ua cov tshuaj tsw qab hauv cov xab npum, tshuaj zawv plaub hau, tshuaj ntxuav tes, thiab tshuaj pleev ib ce txhua hnub.Cinnamonic acid yog siv rau hauv txiv apple tsw, cherry tsw, txiv hmab txiv ntoo tsw, thiab paj tsw qab.Nws muaj cov nyhuv inhibiting kev tsim ntawm dub tyrosinase, muaj ib tug tej yam insulating nyhuv ntawm ultraviolet rays, yuav ua rau xim av me ntsis sib zog los yog txawm ploj, thiab yog ib qho ntawm cov khoom xyaw tseem ceeb hauv cov tshuaj pleev thaiv hnub siab heev.Cinnamic acid nws tus kheej yog ib hom txuj lom, uas muaj cov nyhuv aroma zoo.Nws feem ntau yog siv los ua cov khoom siv raw rau cov tshuaj tsw qab, uas ua rau cov aroma ntawm cov tshuaj tsw qab tseem ceeb ntau volatile.

2. Kev lag luam kws tshuaj

Hauv kev lag luam kws tshuaj, nws tuaj yeem siv los ua cov tshuaj tseem ceeb rau kev sib xyaw thiab kev kho mob ntawm cov kab mob plawv.Nws tuaj yeem siv los ua lub plawv-rau-lub siab thiab lub plawv-rau-lub siab, nrog rau cov hluavtaws chlorpheniric acid thiab cinnamyl piperazine.Nws tuaj yeem siv los ua "Xin Kean", tshuaj loog hauv zos, fungicide, hemostasis.Tshuaj, thiab lwm yam. Chlorobenamide thiab cinnamyl piperazine kuj tseem tuaj yeem ua rau siv los ua cov pob txha txha caj qaum thiab cov tshuaj tua kab mob antispasmodic.Feem ntau yog siv rau cerebral thrombosis, cerebral arteriosclerosis, coronary artery cirrhosis thiab lwm yam kab mob.Nws muaj cov nyhuv inhibitory tseem ceeb ntawm kev loj hlob ntawm lub ntsws adenocarcinoma hlwb.

3. Organic synthesis

Nyob rau hauv cov nqe lus ntawm cov organic tshuaj synthesis, cinnamic acid yuav siv tau raws li ib tug sustained tso tus neeg sawv cev rau galvanized los xij, lub tshav kub stabilizer rau polyvinyl chloride, ib tug crosslinker rau polyurethane, nplaim retardant rau hydantoin thiab polycaprolactam, thiab tshuaj ntsuam xyuas reagent.Nws kuj yog ib qho reagent rau kev txiav txim siab sib cais ntawm uranium thiab vanadium;Nws tseem yog cov khoom siv hluavtaws tseem ceeb tshaj plaws rau cov khoom tsis zoo-hom photosensitive resins.Lub ntsiab hluavtaws lauric acid ester, polyvinyl cawv cinnamate, ethyl ethoxy cinnamate thiab epoxy resin nrog pendant cinnamate.Siv nyob rau hauv cov yas, nws tuaj yeem siv los ua cov cua sov stabilizer rau PVC, los tiv thaiv pwm thiab deodorant rau sterilizing, thiab tseem tuaj yeem muab ntxiv rau hauv cov roj hmab thiab ua npuas ncauj ua rau cov khau deodorant thiab insoles.Nws kuj tseem siv tau rau paj rwb thiab ntau yam hluavtaws fibers, tawv thiab xim.Tiv thaiv mildew hauv cov khoom xws li khau polish thiab straw mats.
