Kufotokozera kwa zinthu
Ethyl vanillin ndi organic compound ndi formula (c2h5o) (ho) c6h3cho. Chomera chopanda utoto chowoneka bwinochi chimakhala ndi mpheta ya benzene ndi hydroxyl, ethoxy, ndi magulu a mawonekedwe pa 4, 3, ndi 1 udindo, motero.
Ethyl Vanillinin ndi mankhwalawa molekyu, osapezeka mwachilengedwe. Yakonzedwa kudzera pa katekiloni yochokera ku katekeleti, kuyambira ndi lukhelation kuti ipatse "GuthOL". Ether Etherh ilililic acid kuti apatse zogwirizana ndi acid acid, yomwe kudzera pa oxidation ndi dekarboxty imapereka ethyl vanillin.
Monga flavorant, ethyl vanillin ndi pafupifupi katatu monga kupezeka ngati vanillin ndipo imagwiritsidwa ntchito popanga chokoleti.

Malangizo okhudzana ndi malonda:
Nthawi zonse timakhala ndi ntchito yovuta kutsimikizira kuti titha kukupatsirani zabwino kwambiri komanso mtengo wogulitsira wabwino kwambiri Ethyl - 121 - 32 - 4 - Mpweya womwe udzapereka kwa padziko lonse lapansi, monga: Mauritius, Swansea, Belgium, chonde sangalalani kwathunthu kuti mulumikizane nafe. Mutha kutumiza maimelo a US ndipo kutilumikizane kuti tifunsitse ndipo tidzakuyankhani mwachangu momwe tingathere. Ngati ndi yophweka, mutha kupeza adilesi yathu patsamba lathu lawebusayiti yathu - Lowani ku bizinesi yathu kuti tidziwe zambiri zazomwe zili nokha. Nthawi zonse timakhala okonzeka kupanga zowonjezera ndi zokhazikika zogwiritsira ntchito zojambulidwa ndi makasitomala aliwonse omwe angakhalepo m'minda yogwirizana.
