Mafotokozedwe Akatundu
Methylparaben, ndi organic mankhwala ndi chilinganizo C8H8O3, woyera crystalline ufa kapena colorless krustalo, ndi sungunuka mowa, efa, pang'ono kwambiri sungunuka m'madzi, otentha mfundo 270-280 °C. Amagwiritsidwa ntchito kwambiri ngati bactericidal preservative for organic synthesis, chakudya, zodzoladzola ndi mankhwala, ndipo amagwiritsidwanso ntchito ngati chakudya chosungira. Chifukwa ili ndi phenolic hydroxyl structure, antibacterial properties ndi yamphamvu kuposa benzoic acid ndi sorbic acid. Limagwirira ake zochita ndi: kuwononga selo nembanemba wa tizilombo, denature mapuloteni mu maselo, ndi ziletsa ntchito ya kupuma michere ndi elekitironi kutengerapo michere ya tizilombo tating'onoting'ono maselo.

Ntchito
Methylparaben ufa uli ndi ntchito zosiyanasiyana, kuphatikiza:
Sterilization ndi antiseptic : Methylparaben imakhala ndi antibacterial ndi bactericidal effect, imatha kuwononga nembanemba ya tizilombo tating'onoting'ono, kusokoneza mapuloteni mu selo, ndikulepheretsa ntchito ya dongosolo la kupuma kwa enzyme ndi ma electron kutengerapo enzyme ya maselo aang'ono. kuti agwire ntchito yotseketsa komanso antiseptic. Katunduyu amapangitsa kuti azigwiritsidwa ntchito kwambiri ngati chosungira zakudya, zodzoladzola, zamankhwala ndi zina.
Anti-inflammatory and antibacterial : Kuwonjezera pa kukhala wotetezera, Methylparaben imakhalanso ndi anti-inflammatory and antibacterial effect ndipo ingagwiritsidwe ntchito pochiza matenda a fungal pakhungu, monga kuyabwa khungu, zotupa pakhungu ndi zizindikiro zina zosasangalatsa. Akagwiritsidwa ntchito pang'onopang'ono, methyl p-hydroxybenzoate imakhala ndi zochizira pakhungu.
Pakuti organic kaphatikizidwe : Methylparaben angagwiritsidwe ntchito monga zopangira organic kaphatikizidwe, makamaka esters ake, monga methyl paraben, ethyl paraben, etc. Esters awa angagwiritsidwe ntchito ngati zowonjezera chakudya, monga soya msuzi, viniga, ozizira zakumwa, zipatso. zokometsera, zipatso ndi ndiwo zamasamba, zosungira zinthu zoziziritsa kukhosi.
Kugwiritsa ntchito mankhwala ndi zodzoladzola : Methylparaben imagwiritsidwa ntchito ngati chosungira mu mankhwala ndi zodzoladzola kuti chakudya chisawole kapena kuti mankhwala asawonongeke. Mu zodzoladzola, zimatha kuletsa zodzoladzola kuti zisawonongeke, kuwonongeka, ndikusunga kutsitsi komanso kuchita bwino kwa zinthu.
Ntchito zina : Methylparaben imagwiritsidwanso ntchito ngati chapakatikati mu utoto, mankhwala ophera tizilombo, komanso mankhwala ophera tizilombo popanga mankhwala ophera tizilombo a organophosphorus. Kuonjezera apo, amagwiritsidwa ntchito popanga ma polima amadzimadzi a crystal ndi mapulasitiki, ndipo monga phenol yochokera ku benzoic acid, amatha kulepheretsa mabakiteriya ambiri a gram-positive ndi mabakiteriya a gram-negative 4.
Mwachidule, ufa wa Methylparaben sikuti umangokhala wothandizira komanso antibacterial wothandizira, komanso umagwira ntchito yofunika kwambiri pakupanga organic ndi minda ina.
Kugwiritsa ntchito
Methylparaben, wotchedwanso methyl paraben kapena methyl hydroxyphenyl ester, ndi woyera crystalline ufa kapena colorless krustalo, sungunuka mowa, etha ndi acetone, pang'ono sungunuka katundu madzi, otentha mfundo 270-280 ° C. Ntchito yaikulu ya izi zophatikiza zikuphatikizapo:
Organic synthesis : Monga zopangira zoyambira za organic synthesis, zomwe zimagwiritsidwa ntchito popanga mankhwala osiyanasiyana.
chakudya chowonjezera : chimagwiritsidwa ntchito ngati mankhwala oteteza ku bactericidal kuteteza chakudya kuti zisawonongeke komanso kuwonjezera moyo wa alumali wa chakudya.
Zodzoladzola : Monga bactericidal preservative of cosmetics, sungani ukhondo ndi khalidwe la zodzoladzola.
mankhwala : methyl p-hydroxybenzoate amagwiritsidwa ntchito ngati mankhwala oteteza bactericidal m'makampani opanga mankhwala kuti atsimikizire chitetezo ndi mphamvu za mankhwala.
Feed preservative : amagwiritsidwa ntchito podyetsa kuteteza kukula kwa tizilombo tating'onoting'ono ndikuwonetsetsa kuti chakudya chili chabwino komanso chitetezo.
Kuphatikiza apo, methyl p-hydroxybenzoate ilinso ndi gulu la phenolic hydroxyl, motero ntchito yake yolimbana ndi mabakiteriya imakhala yamphamvu kuposa benzoic acid ndi sorbate, yomwe imatha kuwononga nembanemba yama cell, ma protein a denature m'maselo, ndikuletsa ntchito za enzyme yopuma. dongosolo ndi ma elekitironi kutengerapo enzyme dongosolo la tizilombo tating'onoting'ono maselo, kuti akwaniritse cholinga odana dzimbiri. Chida ichi chimagwiritsidwa ntchito kwambiri m'magawo ambiri ndipo ndi chinthu chofunikira kwambiri chopangira mankhwala.
