Ingcaciso yeMveliso

I-Methylparaben, yinto ephilayo kunye nefomula ye-C8H8O3, i-crystalline powder emhlophe okanye ikristale engenambala, kunye ne-soluble e-alcohol, i-ether, i-soluble kancinane kakhulu emanzini, indawo ebilayo 270-280 °C. Isetyenziswa ikakhulu njenge bactericidal preservative for organic synthesis, ukutya, izithambiso kunye namayeza, kwaye ikwasetyenziswa njengesondlo sokutya. Ngenxa yokuba inesakhiwo se-phenolic hydroxyl, iimpawu zayo zokulwa ne-antibacterial zinamandla kune-benzoic acid kunye ne-sorbic acid. Indlela yokusebenza kwayo yile: ukutshabalalisa i-membrane yeseli ye-microorganisms, i-denature proteins kwiiseli, kwaye inqanda umsebenzi wee-enzymes zokuphefumula kunye ne-electron transfer enzymes yeeseli ze-microbial.

Umsebenzi

I-Methylparaben powder inemisebenzi eyahlukeneyo, kuquka:

I-Sterrilization kunye ne-antiseptic ‌: I-Methylparaben inefuthe elinamandla lokulwa ne-antibacterial kunye ne-bactericidal, inokutshabalalisa i-membrane yeseli ye-microorganisms, i-denaturate iprotheni kwiseli, kwaye inqanda umsebenzi wenkqubo ye-enzyme yokuphefumla kunye nenkqubo yokudlulisa i-electron yeeseli ze-microbial, ukuze idlale indima yokubulala inzala kunye ne-antiseptic. Le propathi iyenza isetyenziswe ngokubanzi njengendawo yokugcina ukutya, izithambiso, amayeza kunye namanye amacandelo.

I-Anti-inflammatory kunye ne-antibacterial ‌ : Ukongeza kwisilondolozi, i-Methylparaben nayo ineempembelelo ezichasayo kunye ne-antibacterial kwaye ingasetyenziselwa ukunyanga izifo zolusu lomngundo, ezifana nokurhawuzelela ulusu, irhashalala kunye nezinye iimpawu ezingathandekiyo. Ngokusetyenziswa okuphakathi, i-methyl p-hydroxybenzoate ineziphumo ezithile zonyango eluswini.

I-organic synthesis : I-Methylparaben ingasetyenziswa njengezinto eziluhlaza kwi-organic synthesis, ngakumbi ii-esters zayo, ezifana ne-methyl paraben, i-ethyl paraben, njl. Ezi esters zingasetyenziswa njengezongezo zokutya, ezifana nesosi yesoya, iviniga, iziselo zokupholisa, iziqhamo ze-flavoring agents, iziqhamo kunye nemifuno, izigcina-mveliso zemveliso ekhethiweyo.

Ukusetyenziswa kweyeza kunye nezithambiso : I-Methylparaben isetyenziswa njengesigcini kumayeza nakwizithambiso zokuthintela ukutya ekuboleni okanye ukuba iyeza lingahambi kakubi. Kwizinto zokuthambisa, inokuthintela izinto zokuthambisa ekonakalisweni, ekuboleni, kwaye zigcine ukutsha kunye nokusebenza kakuhle kweemveliso.

Olunye usetyenziso : I-Methylparaben ikwasetyenziswa njengendawo ephakathi kwidayi, izibulali-zinambuzane, nakwizitshabalalisi zokwenziwa kwezinambuzane ze-organophosphorus. Ukongeza, isetyenziselwa ukwenziwa kweepolymers zekristale kunye neeplastiki, kwaye njenge-phenol derivative ye-benzoic acid, inokuthintela uninzi lweebhaktheriya zegram-positive kunye nezinye iibhaktheriya zegram-negative 4.

Isishwankathelo, i-Methylparaben powder ayiyona nje into esebenzayo yokugcina kunye ne-antibacterial agent, kodwa idlala indima ebalulekileyo kwi-organic synthesis kunye nezinye iindawo.

Isicelo

I-Methylparaben, ekwabizwa ngokuba yi-methyl paraben okanye i-methyl hydroxyphenyl ester, ngumgubo omhlophe wekristale okanye ikristale engenambala, enyibilika etywaleni, etere kunye ne-acetone, inyibilika kancinci kwiipropati zamanzi, indawo yokubilisa ye-270-280 ° C. Usetyenziso oluphambili lwale khompawundi lubandakanya:

I-Organic synthesis : Njengesiseko semathiriyeli ekrwada ye-organic synthesis, esetyenziselwa ukudibanisa iikhemikhali ezahlukeneyo.
isongezo sokutya : isetyenziswa njengesigcini se-bactericidal ukuthintela ukutya ekonakaleni kunye nokwandisa ubomi beshelufu yokutya.

Izithambiso : Njengesithinteli se-bactericidal sezithambiso, gcina ucoceko kunye nomgangatho wezithambiso.
I-pharmaceuticals : I-methyl p-hydroxybenzoate isetyenziswa njenge-bactericidal preservative kwishishini lamachiza ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwamayeza.

Isondlo esigcinayo : sisetyenziswa kwisondlo ukuthintela ukukhula kweemicroorganisms kunye nokuqinisekisa umgangatho kunye nokhuseleko lokutya.

Ukongeza, i-methyl p-hydroxybenzoate nayo inokwakheka kweqela le-phenolic hydroxyl, ngoko ke ukusebenza kwayo kwe-antibacterial yomelele kune-benzoic acid kunye ne-sorbate, enokuthi itshabalalise i-cell membrane ye-microorganisms, i-denature proteins kwiiseli, kwaye inqanda imisebenzi yenkqubo ye-enzyme yokuphefumla kunye nenkqubo ye-elektroni yokudlulisa i-enzyme yeeseli ze-microbial, ukuze kufezekiswe injongo ye-anticorsion. Le khompawundi isetyenziswa kakhulu kwiinkalo ezininzi kwaye iyimathiriyeli ekrwada yekhemikhali ebalulekileyo.
