I-Methyl Paraben - 99-76-3

I-Methyl paraben, nayo i-mEthyl Paraben, enye yama-parabens, iyisilondolozi esinefomula yamakhemikhali ethi CH3(C6H4(OH)COO). Kuyi-methyl ester ye-p-hydroxybenzoic acid.

Imvelo: i-crystalline powder emhlophe noma i-crystalline. 115-118 ° C indawo encibilikayo, indawo yokubila, 297-298 ° C. Incibilika ku-ethanol, i-ethyl ether ne-acetone, i-micro-soluble emanzini, i-chloroform, i-carbon disulfide ne-petroleum ether. Iphunga elincane elikhethekile kanye nokunambitheka, ukunambitheka okubabayo kancane, uZhuo Ma.

Ukulungiselela: i-p-hydroxybenzoic acid ne-ethanol phambi kwe-sulfuric acid catalyst ye-esterification, i-esterification emanzini ngemva kokuqedwa kwe-crystallization, bese ngokusebenzisa isihlungi, emikhiqizweni yokukhetha.: izinto eziphilayo. Kuma-Preservatives, i-ejenti ye-antimicrobial, esetshenziselwa ukudla, izimonyo kanye nemithi. Futhi isetshenziselwa ukuhlaziya ama-organic reagents. Izimpahla ezikusikhunta, imvubelo kanye namagciwane zinemiphumela ebanzi yokulwa namagciwane, imvubelo nesikhunta endimeni yesikhunta esiqinile, kodwa ikakhulukazi kubhaktheriya i-Gram-negative bacilli kanye nendima ye-Lactobacillus empofu. Ama-fungicides okulondoloza ukudla nemithi.
