Mosebetsi
Methylparaben phofo e na le mesebetsi e fapaneng, ho kenyelletsa:
Sterilization le antiseptic : Methylparaben e na le phello e matla ea antibacterial le bactericidal, e ka senya lera la lisele tsa likokoana-hloko, ea senya protheine ka seleng, le ho thibela ts'ebetso ea tsamaiso ea enzyme ea phefumoloho le tsamaiso ea elektronike ea phetisetso ea elektronike ea lisele tsa likokoana-hloko. ho bapala karolo ea ho thibela likokoana-hloko le likokoana-hloko. Thepa ena e e etsa hore e sebelisoe haholo e le ntho e bolokang lijo, litlolo, meriana le masimong a mang.
Anti-inflammatory and antibacterial : Ntle le ho boloka, Methylparaben e boetse e na le liphello tse khahlanong le ho ruruha le likokoana-hloko 'me e ka sebelisoa ho phekola mafu a letlalo a fungal, a kang ho hlohlona ha letlalo, lekhopho la letlalo le matšoao a mang a sa thabiseng. Ha e sebelisoa ka mokhoa o itekanetseng, methyl p-hydroxybenzoate e na le litlamorao tse itseng tsa kalafo letlalong.
For organic synthesis : Methylparaben e ka sebelisoa e le lisebelisoa tse tala bakeng sa organic synthesis, haholo-holo li-esters tsa eona, tse kang methyl paraben, ethyl paraben, joalo-joalo Li-ester tsena li ka sebelisoa e le li-additives tsa lijo, tse kang soy sauce, asene, lino tse pholileng, litholoana. li-flavoring agents, litholoana le meroho, li-preservatives tsa lihlahisoa tse halikiloeng.
Kopo ho tsa bongaka le litlolo : Methylparaben e sebelisoa e le se bolokang meriana le litlolo ho thibela lijo ho bola kapa meriana hore e se ke ea senyeha. Ho litlolo, e ka thibela litlolo ho senyeha, ho bola, le ho boloka bocha le katleho ea lihlahisoa.
Tšebeliso e 'ngoe: Methylparaben e boetse e sebelisoa e le setsi sa dae, chefo e bolaeang likokoanyana le chefo e bolaeang likokoanyana bakeng sa ho kopanya chefo e bolaeang likokoanyana ea organophosphorus. Ho feta moo, e sebelisoa ha ho etsoa li-polymers le li-plastiki tsa metsi, 'me e le phenol derivative ea benzoic acid, e ka thibela boholo ba libaktheria tsa gram-positive le tse ling tsa gram-negative 4.
Ka bokhutšoanyane, phofo ea Methylparaben hase feela e sebetsang hantle ea ho boloka le ho thibela likokoana-hloko, empa e boetse e phetha karolo ea bohlokoa ho organic synthesis le masimo a mang.
Kopo
Methylparaben, eo hape e tsejoang e le methyl paraben kapa methyl hydroxyphenyl ester, ke phofo e tšoeu ea kristale kapa kristale e se nang mebala, e qhibilihang ka joala, ether le acetone, e qhibilihang hanyenyane haholo ka thepa ea metsi, ntlha e belang ea 270-280 ° C. Tšebeliso e kholo ea sena motsoako o kenyelletsa:
Organic synthesis : Joalo ka thepa ea mantlha ea organic synthesis, e sebelisetsoang ho kopanya lik'hemik'hale tse fapaneng.
tlatsetso ya dijo: e sebedisoang joalo ka sebolaya-baktheria ho thibela dijo hore di se ke tsa senyeha le ho lelefatsa sethala sa bophelo ba dijo.
Cosmetics : Joalo ka sebaki sa bactericidal sa litlolo, boloka bohloeki le boleng ba litlolo.
meriana : methyl p-hydroxybenzoate e sebelisoa e le ntho e thibelang likokoana-hloko indastering ea meriana ho netefatsa polokeho le katleho ea meriana.
Feed preservative : e sebelisoang ho fepa ho thibela kholo ea likokoana-hloko le ho netefatsa boleng le polokeho ea lijo.
Ntle le moo, methyl p-hydroxybenzoate e boetse e na le sebopeho sa sehlopha sa phenolic hydroxyl, ka hona ts'ebetso ea eona ea antibacteria e matla ho feta benzoic acid le sorbate, e ka senyang lera la lisele tsa likokoana-hloko, liprotheine tsa denature liseleng, le ho thibela ts'ebetso ea enzyme ea phefumoloho. tsamaiso le elektrone phetiso enzyme tsamaiso ea lisele tse likokoana-hloko, e le ho finyella morero oa-ba khahlanong le corrosion. Motsoako ona o sebelisoa haholo mafapheng a mangata 'me ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale.
