Zoo siab purity Benzaldehyde CAS 100-52-7 ntawm lag luam wholesale nqe-daim ntawv
Benzaldehyde yog ib qho organic compound, thiab yog synthetized los ntawm txoj kev uas cov hydrogen ntawm benzene yog hloov los ntawm aldehyde. Nws yog qhov yooj yim tshaj plaws, thiab feem ntau siv cov khoom muaj ntxhiab aldehyde. Nws yog cov kua xim tsis muaj xim ntawm chav tsev kub thiab muaj qhov tshwj xeeb almond tsw. Benzaldehyde yog ib tug compound uas aldehyde ncaj qha mus rau phenyl pawg, vim hais tias nws muaj ib tug zoo xws li iab iab almond tsw.
Benzaldehyde dav muaj nyob rau hauv cov nroj tsuag, tshwj xeeb tshaj yog nyob rau hauv cov nroj tsuag Rosaceae. Nws yog tsuas yog nyob rau hauv daim ntawv ntawm glycosides nyob rau hauv cov nroj tsuag qia bark, nplooj los yog noob, xws li amygdalin, iab almond, cherry, laurel, txiv duaj.
Benzaldehyde yog ib txwm nyob rau hauv iab almond roj, patchouli roj, hyacinth roj, cananga roj. Cov tshuaj tseem nyob hauv cov txiv ntoo thiab txiv ntoo, thiab muaj nyob rau hauv daim ntawv ntawm Amygdalin, uas yog ua ke ntawm glycosides. Cov khoom siv tshuaj lom neeg ntawm Benzaldehyde zoo ib yam li aliphatic aldehydes, tab sis nws kuj txawv.
Benzaldehyde tsis tuaj yeem txo fehling reagent. Thaum cov roj txo tau siv los txo cov benzaldehyde, cov khoom tseem ceeb yog benzene methanol, plaub hloov rau ortho-glycol thiab ob-phenyl ethylene glycol. Nyob rau hauv lub xub ntiag ntawm poov tshuaj cyanide, ob lub molecules ntawm benzaldehyde daim ntawv benzoin los ntawm kev txais cov hydrogen atom.
Kev siv Benzaldehyde
1. Benzaldehyde yog ib qho tseem ceeb raw khoom rau tshuaj, dyestuff, naj hoom thiab resin kev lag luam. Nws kuj tuaj yeem siv los ua cov kuab tshuaj, plasticizer thiab cov roj uas tsis muaj kub. Hauv essence, nws yog tsuas yog siv rau kev xa tawm ntawm cov khoom noj qab zib. Ib qho me me ntawm benzaldehyde yog siv txhua hnub hauv qhov tsw thiab tsw ntawm luam yeeb. Txawm hais tias tau dav siv los ua kev lag luam khoom noj khoom haus thiab cov kuab tshuaj ua lag luam, kev siv tseem ceeb ntawm benzyl cawv tseem siv los ua ntau yam ntawm lwm cov tshuaj los ntawm cov tshuaj mus rau cov khoom siv yas. Benzyl cawv yog ib qho tseem ceeb ntawm cov khoom nruab nrab hauv kev tsim cov naj hoom, txuj lom, thiab qee cov aniline dyes.
Mandelic acid tau tsim los ntawm benzaldehyde raws li qhov pib reagent: Nrog thawj hydrocyanic acid reacts nrog benzaldehyde, ces mandelonitrile hydrolyzed rau Racemic mandelic acid. Glacialist LaChepelle thiab Stillman tau tshaj tawm tias Ice crystallization yog inhibited los ntawm benzaldehyde thiab aldehydes ice nyob rau hauv 1966, thiaj li tiv thaiv cov tuab te tsim (Depth Hoar). Cov txheej txheem no tuaj yeem tiv thaiv snowslide tshwm sim los ntawm kev tsis ruaj khov ntawm cov daus npog. Txawm li cas los xij, qhov sib xyaw no tsis tau siv dav, vim tias kev puas tsuaj ntawm cov nroj tsuag thiab cov dej tsis zoo.
2.Nws yog tsuas yog siv rau kev npaj ntawm flavors, xws li almond, Cherry, txiv duaj, txiv ntseej, thiab lwm yam., tus nqi yog mus txog 40%. Raws li aromatizing tus neeg sawv cev cov kaus poom txiv ntoo syrup, ntxiv tus nqi yog qab zib 3mL / kg.
3. Pharmaceutical, dyestuff, txuj lom intermediates.
4.Raws li lub taub hau ntawm cov aroma tshwj xeeb, nws yog siv cov tshuaj tsw qab rau cov tshuaj tsw qab, xws li lilac, dawb, violet, jasmine, acacia, sunflower, qab zib plum, txiv kab ntxwv paj, Tofu paj npleg thiab lwm yam.. Tsis tas li ntawd nws yog siv hauv xab npum. Tsis tas li ntawd nws tuaj yeem siv ua txuj lom rau almond, txiv maj phaub qab zib, berries, cherries, apricots, txiv duaj, plums, walnuts, thiab vanilla taum, ntsim tsw. Caw nrog flavors xws li rum, brandy, thiab lwm yam.
5. Benzaldehyde yog ib qho nruab nrab ntawm cov tshuaj tua kab mob, cog kev loj hlob regulator, thiab anti-amine.
6. Siv los ua reagent rau kev txiav txim siab ntawm ozone, phenol, alkaloid thiab methylene. Siv nyob rau hauv kev npaj ntawm txuj lom.
