Methylparaben, bụ ihe organic nke nwere usoro C8H8O3, ntụ ntụ ọcha ma ọ bụ kristal na-enweghị agba, nke nwere soluble na mmanya na-aba n'anya, ether, soluble dị ntakịrị na mmiri, ebe esi 270-280 Celsius. A na-ejikarị ya dị ka ihe nchekwa nje bacteria maka njikọ organic, nri, ihe ịchọ mma na ọgwụ, a na-ejikwa ya dị ka ihe nchekwa nri. N'ihi na o nwere usoro hydroxyl phenolic, ihe ndị na-egbu nje ya dị ike karịa benzoic acid na sorbic acid. Usoro ya na-eme bụ: ibibi akpụkpọ ahụ nke microorganisms, protein denature na sel, na igbochi ọrụ nke enzymes iku ume na electron transfer enzymes nke microbial cell.

Methylparaben ntụ ntụ nwere ọtụtụ ọrụ, gụnyere:
Sterilisation na antiseptik : Methylparaben nwere mmetụta antibacterial na nje bacteria siri ike, nwere ike ibibi akpụkpọ ahụ cell nke microorganisms, denaturate protein na cell, na-egbochi ọrụ nke usoro iku ume enzyme usoro na electron transfer enzyme system of microbial cell, ya mere, iji rụọ ọrụ nke sterilization na antiseptik. Ihe onwunwe a na-eme ka a na-eji ya eme ihe n'ọtụtụ ebe dị ka ihe nchekwa nri, ihe ịchọ mma, ọgwụ na ubi ndị ọzọ.
Mgbochi na-egbu egbu na nje bacteria : Na mgbakwunye na ịbụ ihe nchekwa, Methylparaben nwekwara mmetụta mgbochi mkpali na nje bacteria na enwere ike iji ya na-agwọ ọrịa fungal akpụkpọ anụ, dị ka itching akpụkpọ, akpụkpọ rashes na ndị ọzọ na-adịghị mma mgbaàmà. Na agafeghị oke ojiji, methyl p-hydroxybenzoate nwere ụfọdụ ọgwụgwọ mmetụta na akpụkpọ.
N'ihi na organic synthesis : Methylparaben nwere ike iji dị ka akụrụngwa maka organic synthesis, karịsịa ya esters, dị ka methyl paraben, ethyl paraben, wdg Esters ndị a nwere ike iji dị ka nri mgbakwunye, dị ka soy sauce, mmanya, jụrụ oyi, mkpụrụ osisi. ihe na-esi ísì ụtọ, mkpụrụ osisi na akwụkwọ nri, ihe nchekwa maka ngwaahịa pickled.
Ngwa na nkà mmụta ọgwụ na ihe ntecha: Methylparaben na-eji dị ka ihe nchekwa na nkà mmụta ọgwụ na ịchọ mma iji gbochie nri ire ere ma ọ bụ ọgwụ na-adịghị njọ. N'ihe ịchọ mma, ọ nwere ike igbochi ihe ịchọ mma ka ọ ghara imebi, ire ere, ma nọgide na-adị ọhụrụ na ịdị irè nke ngwaahịa.
Ojiji ndị ọzọ : Methylparaben na-ejikwa dị ka onye na-agbapụta ihe na-esiji esiji, ọgwụ na-egbu egbu, na ọgwụ pesticides maka njikọ nke organophosphorus ụmụ ahụhụ. Na mgbakwunye, a na-eji ya na-emepụta polymers kristal mmiri mmiri na plastik, yana dị ka phenol sitere na benzoic acid, nwere ike igbochi ọnụ ọgụgụ ka ukwuu nke nje bacteria gram-positive na ụfọdụ nje gram-adịghị mma 4.
Na nchịkọta, Methylparaben ntụ ntụ abụghị nanị ihe nchebe dị irè na onye na-ahụ maka nje bacteria, ma na-arụkwa ọrụ dị mkpa na njikọ organic na ubi ndị ọzọ.
Ngwa
Methylparaben, nke a makwaara dị ka methyl paraben ma ọ bụ methyl hydroxyphenyl ester, bụ crystalline ntụ ntụ ma ọ bụ colorless crystal, soluble na mmanya, ether na acetone, dị nnọọ ubé soluble na mmiri Njirimara, esi isi 270-280 Celsius C. Isi ojiji nke a. Ngwakọta gụnyere:
Organic synthesis: Dị ka ihe bụ isi akụrụngwa nke organic synthesis, eji synthesize iche iche chemicals.
Ihe mgbakwunye nri: ejiri ya dị ka ihe nchekwa nje na-egbochi nri ịla n'iyi ma gbatịkwuo ndụ nri.
Ihe ịchọ mma : Dị ka ihe na-echekwa ihe ịchọ mma nke nje bacteria, na-echekwa ịdị ọcha na ịdị mma nke ihe ịchọ mma.
A na-eji ọgwụ ọgwụ: methyl p-hydroxybenzoate mee ihe dị ka ihe nchekwa bactericidal na ụlọ ọrụ ọgwụ iji hụ na nchekwa na ịdị irè nke ọgwụ.
Ihe nchekwa nri: ejiri ya na nri iji gbochie uto nke microorganisms ma hụ na ịdịmma na nchekwa nke nri.
Ke adianade do, methyl p-hydroxybenzoate nwekwara a phenolic hydroxyl otu Ọdịdị, ya mere, ya antibacterial arụmọrụ dị ike karịa benzoic acid na sorbate, nke nwere ike ibibi cell akpụkpọ anụ nke microorganisms, denature proteins na mkpụrụ ndụ, na-egbochi ọrụ nke iku ume enzymes. usoro na electron nyefe enzyme usoro nke microbial cell, nke mere iji nweta nzube nke mgbochi corrosion. A na-eji ngwakọta a eme ihe n'ọtụtụ ebe ma bụrụ ihe dị mkpa kemịkalụ akụrụngwa.
