I-Factory Supply CAS 99-76-3 Methylparaben Pure Methylparaben Powder
Incazelo Yomkhiqizo
I-Methylparaben, into ephilayo enefomula ethi C8H8O3, i-crystalline powder emhlophe noma ikristalu engenambala, encibilika otshwaleni, i-ether, inyibilika kancane emanzini, iphoyinti elibilayo elingu-270-280 °C. Isetshenziswa kakhulu njengesivikeli se-bactericidal se-organic synthesis, ukudla, izimonyo kanye nemithi, futhi isetshenziswa njengesivikeli sokudla. Ngenxa yokuthi inesakhiwo se-phenolic hydroxyl, izakhiwo zayo ze-antibacterial zinamandla kune-benzoic acid ne-sorbic acid. Indlela yokusebenza yayo yile: ukubhubhisa ulwelwesi lweseli lwama-microorganisms, amaprotheni e-denature kumaseli, futhi avimbele umsebenzi wama-enzyme okuphefumula kanye nama-enzyme okudlulisa ama-electron amaseli amancane.

Umsebenzi
I-Methylparaben powder inemisebenzi eyahlukene, ehlanganisa:
Ukwenziwa inzalo kanye ne-antiseptic : I-Methylparaben inomphumela oqinile we-antibacterial kanye ne-bactericidal, ingabhubhisa ulwelwesi lwamangqamuzana amagciwane, ikhiphe amaprotheni esitokisini, futhi ivimbele ukusebenza kohlelo lwe-enzyme yokuphefumula kanye nohlelo lwe-elektroni lokudlulisa amaseli amancane, ukuze idlale indima yokubulala inzalo kanye ne-antiseptic. Lesi sakhiwo sikwenza kusetshenziswe kabanzi njengesilondolozi ekudleni, kwezimonyo, emithini nakweminye imikhakha.
I-Anti-inflammatory and antibacterial : Ngaphezu kokuba isilondolozi, i-Methylparaben nayo inemiphumela elwa nokuvuvukala kanye ne-antibacterial futhi ingasetshenziselwa ukwelapha izifo zesikhumba zesikhunta, njengokulunywa kwesikhumba, ukuqubuka kwesikhumba nezinye izimpawu ezingemnandi. Uma isetshenziswa ngokusesilinganisweni, i-methyl p-hydroxybenzoate inemiphumela ethile yokwelapha esikhumbeni .
I-organic synthesis : I-Methylparaben ingasetshenziswa njengezinto ezingavuthiwe ze-organic synthesis, ikakhulukazi ama-esters ayo, njenge-methyl paraben, i-ethyl paraben, njll. Lawa ma-ester angasetshenziswa njengezithasiselo zokudla, njengesosi yesoso, uviniga, iziphuzo ezipholile, ama-agent afaka isiphuzo esithelweni, izithelo nemifino, izilondolozi zemikhiqizo ekhethiwe.
Ukusetshenziswa kwezokwelapha nezimonyo : I-Methylparaben isetshenziswa njengesilondolozi emithini nasezimonyoni ukuvimbela ukudla ukuthi kungaboli noma umuthi ungoni. Kwezimonyo, ingavimbela izimonyo ukuthi zingaboli, zibole, futhi zigcine ubusha nokusebenza kwemikhiqizo .
Okunye ukusetshenziswa : I-Methylparaben iphinde isetshenziswe njengendawo ephakathi kodayi, izibulala-zinambuzane, nezibulala-zinambuzane ukuze kuhlanganiswe izibulala-zinambuzane ze-organophosphorus. Ngaphezu kwalokho, isetshenziswa ekwenzeni ama-polymers e-crystal ewuketshezi namapulasitiki, futhi njenge-phenol derivative ye-benzoic acid, ingavimbela iningi lama-bacterium e-gram-positive namanye amagciwane e-gram-negative 4.
Kafushane, i-Methylparaben powder ayiyona nje i-preservative esebenzayo kanye ne-antibacterial agent, kodwa futhi idlala indima ebalulekile ekuhlanganiseni kwezinto eziphilayo nakweminye imikhakha.
Isicelo
I-Methylparaben, eyaziwa nangokuthi i-methyl paraben noma i-methyl hydroxyphenyl ester, iyimpushana emhlophe ecwebezelayo noma ikristalu engenambala, inyibilika otshwaleni, i-ether ne-acetone, inyibilika kancane ezindaweni zamanzi, indawo abilayo engu-270-280 ° C. Ukusetshenziswa okuyinhloko kwalesi sakhi kuhlanganisa:
I-Organic synthesis : Njengempahla eyisisekelo ye-organic synthesis, esetshenziselwa ukuhlanganisa amakhemikhali ahlukahlukene.
isithako sokudla : sisetshenziswa njengesilondolozi esibulala amagciwane ukuvimbela ukudla ukuthi kungonakali futhi kunwebe isikhathi seshelufu sokudla.
Izimonyo : Njengesilondolozi esibulala amagciwane sezimonyo, gcina inhlanzeko nekhwalithi yezimonyo.
i-pharmaceutical : I-methyl p-hydroxybenzoate isetshenziswa njengesilondolozi esibulala amagciwane embonini yezemithi ukuze kuqinisekiswe ukuphepha nokusebenza ngempumelelo kwemithi.
I-feed preservative : isetshenziswa ekuphakeleni ukuvimbela ukukhula kwamagciwane kanye nokuqinisekisa ikhwalithi nokuphepha kokuphakelayo.
Ngaphezu kwalokho, i-methyl p-hydroxybenzoate nayo inokwakheka kweqembu le-phenolic hydroxyl, ngakho-ke ukusebenza kwayo kwe-antibacterial kunamandla kune-benzoic acid ne-sorbate, engacekela phansi ulwelwesi lwamangqamuzana amagciwane, amaprotheni e-denature kumaseli, futhi ivimbele imisebenzi yohlelo lwe-enzyme yokuphefumula kanye nohlelo lwe-elektroni lokudlulisa amaseli amagciwane, ukuze kufezwe inhloso ye-anticorrosion. Le nhlanganisela isetshenziswa kabanzi emikhakheni eminingi futhi iyi-chemical material eluhlaza .
