IMethyl Paraben｜99-76-3

I-Methyl paraben, nayo i-mEthyl Paraben, enye ye-parabens, i-preservative kunye ne-chemical formula CH3(C6H4(OH)COO). Yi-methyl ester ye-p-hydroxybenzoic acid.

Indalo: i-crystalline powder emhlophe okanye i-crystalline. I-115-118 ° C indawo yokunyibilika, indawo yokubilisa, i-297-298 ° C. Inyibilika kwi-ethanol, i-ethyl ether kunye ne-acetone, i-micro-soluble emanzini, i-chloroform, i-carbon disulfide kunye ne-petroleum ether. Ivumba elincinane elikhethekileyo kunye nencasa, incasa ekrakra kancinane, uZhuo Ma.

Ukulungiselela: i-p-hydroxybenzoic acid kunye ne-ethanol phambi kwe-sulfuric acid catalyst ye-esterification, i-esterification emanzini emva kokugqitywa kwe-crystallization, emva koko ngesihluzo, kwiimveliso zokukhetha.Sebenzisa: izinto eziphilayo. Kwi-Preservatives, i-antimicrobial agent, esetyenziselwa ukutya, izimonyo kunye namayeza. Ikwasetyenziselwa uhlalutyo lwe-organic reagents. Impahla ekwisikhunta, igwele kunye neebhaktheriya zineempembelelo zokulwa neentsholongwane ezibanzi, igwele kunye nokungunda kwindima eyomeleleyo, kodwa ngakumbi kwiibhaktheriya ze-Gram-negative bacilli kunye nendima yeLactobacillus empofu. Ukutya kunye namayeza ngokufanelekileyo ulondolozo lokungunda.
