ʻO ka Methyl paraben, a me ka mEthyl Paraben, kekahi o nā parabens, he mea mālama me ke ʻano kemika CH3(C6H4(OH)COO). ʻO ia ka methyl ester o ka p-hydroxybenzoic acid.
ʻAno: he pauka keʻokeʻo keʻokeʻo a i ʻole ke aniani. 115-118 ° C melting point, boiling point, 297-298 ° C. Soluble in ethanol, ethyl ether and acetone, micro-soluble in water, chloroform, carbon disulfide and petroleum ether. ʻO ka ʻala kūikawā liʻiliʻi a me ka ʻono, ka ʻono ʻawaʻawa, Zhuo Ma.
Hoʻomākaukau: p-hydroxybenzoic acid a me ka ethanol i ke alo o ka sulfuric acid catalyst no ka esterification, esterification i ka wai ma hope o ka pau ʻana o ka crystallization, a laila ma o kahi kānana, i nā huahana pickling.: nā mea waena kūlohelohe. No nā Preservatives, antimicrobial agent, hoʻohana ʻia i ka meaʻai, nā mea hoʻonaninani a me nā lāʻau lapaʻau. Hoʻohana pū ʻia no ka nānā ʻana i nā reagents organik. ʻO nā waiwai ma ka mold, yeast a me ka bacteria he ākea antibacterial hopena, yeast a me ka mold i ke kuleana o kahi ikaika, akā no ka bacteria Gram-negative bacilli a me ke kuleana o Lactobacillus poor. ʻO ka meaʻai a me ka lāʻau lapaʻau e mālama pono i nā fungicides.
