Botanical molluscicide CNM-30
Tlhaloso ea Lihlahisoa
Methyl paraben, hape le mEthyl Paraben, e 'ngoe ea li-parabens, ke se sireletsang ka mokhoa oa lik'hemik'hale CH3(C6H4(OH)COO). Ke methyl ester ea p-hydroxybenzoic acid.
Tlhaho: phofo kapa kristale e mosoeu. 115-118 ° C ntlha ea ho qhibiliha, ntlha e belang, 297-298 ° C. E qhibiliha ka ethanol, ethyl ether le acetone, e qhibilihang ka har'a metsi, chloroform, carbon disulfide le petroleum ether. Monko o monyane o khethehileng le tatso, tatso e babang hanyane, Zhuo Ma.
Tokisetso: p-hydroxybenzoic acid le ethanol boteng ba sulfuric acid catalyst for esterification, esterification ka metsing ka mor'a ho phethoa ha crystallization, ebe ka sesefa, lihlahisoa tsa pickling. Sebelisa: lintho tse phelang lipakeng. Bakeng sa Li-Preservatives, moemeli oa likokoana-hloko, o sebelisoang lijong, litlolo le meriana. E boetse e sebelisetsoa ho hlahloba li-reagents tsa organic. Thepa e holim'a hlobo, tomoso le libaktheria li na le litlamorao tse ngata tsa antibacteria, tomoso le hlobo ho nka karolo e matla, empa haholo bakeng sa baktheria ea Gram-negative bacilli le karolo ea Lactobacillus e futsanehileng. Li-fungicides tse bolokang lijo le meriana ka katleho.
