Hāʻawi hale hana CAS 99-76-3 Methylparaben Pure Methylparaben Powder
Hōʻike huahana
ʻO Methylparaben, he mea olaola me ke ʻano C8H8O3, ka pauka crystalline keʻokeʻo a i ʻole ke aniani kala ʻole, me ka hoʻoheheʻe ʻia i loko o ka waiʻona, etera, hiki ke hoʻoheheʻe ʻia i ka wai, kahi e hoʻolapalapa ai 270-280 °C. Hoʻohana nui ʻia ia ma ke ʻano he bactericidal preservative no ka synthesis organik, ka meaʻai, nā mea hoʻonaninani a me nā lāʻau lapaʻau, a hoʻohana ʻia hoʻi i mea mālama hānai. No ka mea he phenolic hydroxyl structure, ʻoi aku ka ikaika o kāna mau antibacterial ma mua o ka benzoic acid a me ka waikawa sorbic. ʻO kāna hana o ka hana ʻo ia: luku i ka membrane cell o nā microorganisms, denature proteins i loko o nā pūnaewele, a keʻakeʻa i ka hana o nā enzymes hanu a me nā enzymes transfer electron o nā pūnaewele microbial.

Hana
He ʻano hana like ʻole ka pauka Methylparaben, me:
Sterilization a me ka antiseptic : Methylparaben he ikaika antibacterial a me ka hopena bactericidal, hiki ke hoʻopau i ka membrane cell o nā microorganisms, denaturate i ka protein i loko o ke kelepona, a keʻakeʻa i ka hana o ka ʻōnaehana enzyme hanu a me ka ʻōnaehana electron transfer enzyme o nā cell microbial. e pāʻani i ka hana o ka sterilization a me ka antiseptic. Hoʻohana nui ʻia kēia waiwai ma ke ʻano he preservative i ka meaʻai, nā mea hoʻonaninani, nā lāʻau lapaʻau a me nā māla ʻē aʻe .
Anti-inflammatory a me antibacterial : Ma kahi o ka mālama ʻana, loaʻa iā Methylparaben nā hopena anti-inflammatory a me antibacterial a hiki ke hoʻohana ʻia no ka mālama ʻana i nā maʻi ʻili fungal, e like me ka ʻili ʻili, nā ʻili ʻili a me nā hōʻailona maikaʻi ʻole. Ma ka hoʻohana maʻalahi, loaʻa ka methyl p-hydroxybenzoate i kekahi mau hopena therapeutic ma ka ʻili .
No ka mea hoʻolalelale : Hiki ke hoʻohana ʻia ka Methylparaben ma ke ʻano he mea maka no ka synthesis organik, ʻoi aku ka nui o kāna esters, e like me methyl paraben, ethyl paraben, etc. nā mea ʻono, nā huaʻai a me nā mea kanu, nā preservatives no nā huahana pickled .
Hoʻohana i ka lāʻau lapaʻau a me nā mea hoʻonaninani : Hoʻohana ʻia ʻo Methylparaben ma ke ʻano he mea mālama i ka lāʻau lapaʻau a me nā mea hoʻonaninani e pale ai i ka meaʻai mai ka popopo a i ʻole ka lāʻau mai ka hewa. I nā mea hoʻonaninani, hiki iā ia ke pale i nā mea hoʻonaninani mai ka palaha, decomposition, a mālama i ka hou a me ka pono o nā huahana .
Hoʻohana ʻē aʻe : Hoʻohana pū ʻia ʻo Methylparaben ma ke ʻano he mea waena i loko o ka wai, nā pesticides, a me nā pesticides no ka synthesis o organophosphorus insecticides. Eia kekahi, hoʻohana ʻia ia i ka hana ʻana i nā polymers kristal wai a me nā plastics, a ma ke ʻano he phenol derivative o ka benzoic acid, hiki ke kāohi i ka hapa nui o nā hua bacteria gram-positive a me kekahi mau bacteria gram-negative 4.
I ka hōʻuluʻuluʻana,ʻo ka pauka Methylparabenʻaʻole ia he mea mālama pono a me ka antibacterial agent, akā he hana koʻikoʻi hoʻi i ka synthesis organik a me nā māla'ē aʻe.
Palapala noi
ʻO ka Methylparaben, ka mea i kapa ʻia ʻo methyl paraben a i ʻole methyl hydroxyphenyl ester, he pauka keʻokeʻo keʻokeʻo a i ʻole ke aniani kala ʻole, hiki ke hoʻoheheʻe ʻia i ka waiʻona, etera a me ka acetone, hiki ke hoʻoheheʻe ʻia i loko o nā wai wai, kahi paila o 270-280 ° C. ʻO ka hoʻohana nui o kēia. hui pū ʻia me:
Organic synthesis : Ma ke ʻano kumu kumu o ka synthesis organik, hoʻohana ʻia e synthesize i nā ʻano kemika.
mea hoʻohui meaʻai: hoʻohana ʻia ma ke ʻano he mālama bactericidal e pale ai i ka meaʻai mai ka palaha a hoʻonui i ke ola o ka meaʻai.
Cosmetics : Ma ke ʻano he mālama bactericidal o nā mea hoʻonaninani, mālama i ka maʻemaʻe a me ka maikaʻi o nā mea hoʻonaninani.
lāʻau lapaʻau : methyl p-hydroxybenzoate hoʻohana ʻia ma ke ʻano he mālama bactericidal i ka ʻoihana lāʻau lapaʻau e hōʻoia i ka palekana a me ka pono o nā lāʻau lapaʻau.
Mea mālama hānai : hoʻohana ʻia i ka hānai e pale i ka ulu ʻana o nā microorganism a hōʻoia i ka maikaʻi a me ka palekana o ka hānai.
Eia kekahi, ʻo ka methyl p-hydroxybenzoate ka pūʻulu phenolic hydroxyl pūʻulu, no laila ʻoi aku ka ikaika o kāna hana antibacterial ma mua o ka benzoic acid a me ka sorbate, hiki ke hoʻopau i ka membrane cell o nā microorganisms, denature proteins i loko o nā ʻāpana, a ke kāohi i nā hana o ka hanu hanu. ʻōnaehana a me ka electron transfer enzyme system of microbial cell, i mea e hoʻokō ai i ke kumu o ka anti-corrosion. Hoʻohana nui ʻia kēia pūhui i nā ʻāina he nui a he mea waiwai nui kemika .
