Iyini i-Sodium Dehydroacetate CAS 4418-26-2?

I-sodium dehydroacetate iyimpushana emhlophe ecwebezelayo encibilika kalula emanzini. Ibonisa i-asidi ebuthakathaka emanzini futhi ingakhulula igesi ye-SO2 ngaphansi kwezimo ezine-acidic. I-sodium dehydroacetate iyisivikeli sokudla esine-spectrum ebanzi futhi esilwa namagciwane kakhulu, esinekhono eliqinile lokuvimbela isikhunta nemvubelo. Ngesilinganiso esifanayo, umphumela we-antibacterial uphakeme izikhathi eziningana noma ngisho namashumi ezikhathi eziyishumi kune-benzoate ye-sodium esetshenziswa kabanzi ne-potassium sorbate. Okubaluleke kakhulu ukuthi kunomphumela omncane ovimbela amagciwane akhiqiza i-asidi, ikakhulukazi amagciwane e-lactic acid.

Isicelo

I-1.I-sodium dehydroacetate iyi-ejenti elwa namagciwane enokuphepha okuphezulu, uhla olubanzi lwe-antibacterial, kanye nekhono elinamandla lokulwa namagciwane. Akuthintwa kancane ubumuncu noma i-alkalinity yokudla futhi ingagcina ukusebenza kahle kwe-antibacterial ephezulu ngaphansi kwezimo ezine-asidi noma ezine-alkali kancane. Ikhono layo lokulwa namagciwane liphakeme kune-sodium benzoate, i-potassium sorbate, i-calcium propionate, njll., okuyenza ibe isilondolozi esifanelekile sokudla.
2. I-sodium dehydroacetate ingasetshenziselwa ukwelashwa kwendawo yensimbi, ukususa amafutha, nokuvimbela ukugqwala ezindaweni zensimbi,
3. I-sodium dehydroacetate nayo ingasetshenziselwa ukuhlaziywa kwamakhemikhali kanye nokulungiswa kwama-mordants.
I-4.I-sodium dehydroacetate iphinde isetshenziswe emkhakheni wokwenza iphepha, isikhumba, ukugqoka, izimonyo, njll.
