benzoic asidi

benzoic asidi

Amatchedwanso: benzoic acid

Tanthauzo: Fomula yamankhwala ndi C6H5COOH, yomwe imapangidwa ndi okosijeni wa toluene. Amagwiritsidwa ntchito kwambiri ngati chosungira, mankhwala ophera tizilombo, komanso amagwiritsidwa ntchito ngati mankhwala ndi mankhwala apakatikati.

Mutu: Chemical noun_raw materials ndi mankhwala

Mawu ogwirizana: sodium benzoate, cholesteryl benzoate, chakudya chosungira.

Benzoic acid ndi mchere wake wa sodium (sodium benzoate) ndizomwe zimagwiritsidwa ntchito posungira chakudya. Lili ndi mphamvu zowononga zowononga kwambiri pansi pa acidic ndipo zimakhala ndi zotsatira zolepheretsa kukula kwa bowa, mabakiteriya ndi nkhungu. Akagwiritsidwa ntchito ngati mankhwala, benzoic acid nthawi zambiri amagwiritsidwa ntchito pakhungu limodzi ndi salicylic acid pochiza matenda a khungu monga zipere. Benzoic asidi ndi zopangira kupanga mankhwala ophera tizilombo, utoto, mankhwala, zonunkhira, mordants ndi plasticizers. Ndiwosinthiranso ma resins a polyamide ndi ma alkyd resins komanso choletsa dzimbiri pazida zachitsulo. Kuphatikiza apo, asidi a benzoic amathanso kugwiritsidwa ntchito pakupanga ulusi, utomoni, zokutira, mphira ndi mafakitale afodya.

Sodium benzoate ndi yofanana ndi potaziyamu sorbate. Benzoic acid ndi mchere wake wa sodium amapezeka mwachilengedwe m'zomera (makamaka zipatso), koma nthawi zambiri amapezeka m'mafakitale pogwiritsa ntchito kaphatikizidwe ka mankhwala. Sodium benzoate ili ndi ntchito zosiyanasiyana monga zosungira ndipo nthawi zambiri imagwiritsidwa ntchito pazakudya (monga vinyo wosasa, msuzi wa soya, nyama, nsomba, zakudya zokazinga, ndi zina zambiri), zakumwa (makamaka zakumwa zozizilitsa kukhosi) ndi zinthu zosamalira anthu (zo utoto, zodzoladzola). , etc.) Kukonzekera) ndi mafakitale ena, amagwiritsidwa ntchito kwambiri m'mayiko padziko lonse lapansi.

Kuphatikiza pa kugwiritsidwa ntchito ngati chosungira, benzoic acid imakhalanso yapakatikati mu kaphatikizidwe ka organic. Cholesterol benzoate ndiye chinthu choyambirira kwambiri chamadzimadzi chamadzimadzi chomwe anthu adatulukira ndipo ndicho chigawo chachikulu cha makristasi amadzimadzi. Itha kugwiritsidwa ntchito ngati kristalo wamadzi a thermochromic atasakanizidwa ndi mafuta a cholesterol nonanoate ndi cholesterol oleyl alcohol carbonate, ndipo amagwiritsidwa ntchito kwambiri popanga ma CD abodza. Kuphatikiza apo, cholesteryl benzoate ndi yapakatikati pakuphatikizika kwa vitamini D3.

Methyl benzoate imapezeka mwachilengedwe mu mafuta a clove, mafuta a ylang-ylang ndi mafuta a tuberose. Lili ndi fungo lamphamvu ndipo nthawi zambiri limagwiritsidwa ntchito popanga mafuta onunkhira komanso mafuta opangira. Itha kugwiritsidwanso ntchito ngati organic zosungunulira. Ethyl benzoate imapezeka mwachilengedwe m'masamba a fodya ochiritsidwa ndi flue, mapichesi, chinanazi ndi tiyi wakuda. Ndi gawo la zokometsera zachilengedwe komanso zopangira ndipo zitha kugwiritsidwa ntchito kupanga zokometsera za zipatso, ndi zina zambiri. Propyl benzoate imapezeka mwachilengedwe mu yamatcheri okoma, zimayambira za clove, ndi batala. Ili ndi fungo la mtedza kapena zipatso ndipo imagwiritsidwa ntchito muzakudya ngati fungo lopangira. Ilinso ndi antimicrobial properties ndipo imagwiritsidwa ntchito ngati chosungira mu zodzoladzola.
