Mawu a sayansi ndi ukadaulo wa tsiku ndi tsiku | benzoic acid

asidi wa benzoic

asidi wa benzoic

Amadziwikanso kuti: benzoic acid

Tanthauzo: Fomula ya mankhwala ndi C6H5COOH, yomwe imapangidwa ndi okosijeni wa toluene. Imagwiritsidwa ntchito makamaka ngati chosungira, chophera tizilombo toyambitsa matenda, komanso ngati mankhwala ochiritsira komanso mankhwala.

Mutu: Mankhwala_zida zopangira ndi zinthu

Mawu ofanana: sodium benzoate, cholesterol benzoate, chosungira chakudya.

Benzoic acid ndi mchere wake wa sodium (sodium benzoate) ndi zinthu zosungira zakudya zomwe zimagwiritsidwa ntchito kwambiri. Ili ndi mphamvu yoteteza ku matenda a bakiteriya kwambiri m'malo okhala ndi asidi ndipo imaletsa kukula kwa bowa, mabakiteriya ndi nkhungu. Ikagwiritsidwa ntchito ngati mankhwala, benzoic acid nthawi zambiri imagwiritsidwa ntchito pakhungu limodzi ndi salicylic acid pochiza matenda a pakhungu monga mphutsi. Benzoic acid ndi chinthu chopangira mankhwala ophera tizilombo, utoto, mankhwala, zonunkhira, ma mordants ndi ma plasticizers. Imakhalanso chosinthira ma polyamide resins ndi ma alkyd resins komanso choletsa dzimbiri pazida zachitsulo. Kuphatikiza apo, benzoic acid ingagwiritsidwenso ntchito m'mafakitale opanga ulusi, utomoni, zokutira, mphira ndi fodya.

Sodium benzoate ndi yofanana ndi potaziyamu sorbate. Benzoic acid ndi mchere wake wa sodium zimapezeka mwachilengedwe m'zomera (makamaka zipatso), koma nthawi zambiri zimapezeka m'mafakitale kudzera mu kapangidwe ka mankhwala. Sodium benzoate imagwiritsidwa ntchito mosiyanasiyana ngati chosungira ndipo nthawi zambiri imagwiritsidwa ntchito muzakudya (monga viniga, soya msuzi, nyama, nsomba, zakudya zokazinga, ndi zina zotero), zakumwa (makamaka zakumwa zoziziritsa kukhosi) ndi zinthu zosamalira thupi (utoto, zodzoladzola, ndi zina zotero) Zokonzekera) ndi mafakitale ena, imagwiritsidwa ntchito kwambiri m'maiko osiyanasiyana padziko lonse lapansi.

Kuwonjezera pa kugwiritsidwa ntchito ngati chosungira, benzoic acid ndi gawo lapakati pa kapangidwe ka organic. Cholesterol benzoate ndiye chinthu choyambirira kwambiri cha kristalo chamadzimadzi chomwe chinapezeka ndi anthu ndipo ndiye gawo lalikulu la makristalo amadzimadzi owonetsera. Itha kugwiritsidwa ntchito ngati kristalo wamadzimadzi wa thermochromic itatha kusakanikirana ndi cholesterol nonanoate ndi cholesterol oleyl alcohol carbonate, ndipo imagwiritsidwa ntchito kwambiri pantchito yoletsa kupanga zinthu zabodza. Kuphatikiza apo, cholesteryl benzoate ndi gawo lapakati pakupanga vitamini D3.

Methyl benzoate imapezeka mwachilengedwe mu mafuta a clove, mafuta a ylang-ylang ndi mafuta a tuberose. Ili ndi fungo lamphamvu ndipo nthawi zambiri imagwiritsidwa ntchito popanga zonunkhira ndi mafuta ofunikira opangidwa. Ingagwiritsidwenso ntchito ngati chosungunulira chachilengedwe. Ethyl benzoate imapezeka mwachilengedwe mu masamba a fodya otsukidwa ndi flue, mapichesi, chinanazi ndi tiyi wakuda. Ndi gawo la zokometsera zina zachilengedwe komanso zopangidwa ndipo ingagwiritsidwe ntchito kupanga zokometsera za zipatso, ndi zina zotero. Propyl benzoate imapezeka mwachilengedwe mu ma cherries otsekemera, tsinde la clove, ndi batala. Ili ndi fungo la mtedza kapena zipatso ndipo imagwiritsidwa ntchito muzakudya ngati zokometsera zopangidwa. Ilinso ndi mphamvu zopha tizilombo toyambitsa matenda ndipo imagwiritsidwa ntchito ngati chosungira mu zodzoladzola.
