Cov Sodium Benzoateyog milky dawb particle teeb meem los sis crystalline hmoov, tsw ntxhiab tsw los yog microstrip benzine tsw, qab zib, astringent tsw. Kuj hu uasodium benzoate, tus txheeb ze molecular qhov hnyav yog 144.12. Ruaj rau hauv huab cua, soluble hauv dej, nws cov txiaj ntsig PH tus nqi ntawm 8, yaj hauv cawv. Benzoic acid thiab acid yog dav spectrum antimicrobial tus neeg sawv cev, tab sis lawv cov kab mob tua kab mob yog nyob ntawm PH tus nqi ntawm cov zaub mov. Nrog rau qhov nce nqi ntawm cov kua qaub ua kom muaj nuj nqis, cov kab mob thiab bacteriostatic muaj ntau ntxiv, tab sis cov kab mob bactericidal thiab cov kab mob bacteriostatic ploj hauv alkali tshuaj. Tsim nyog PH tus nqi rau kev tiv thaiv xeb yog 2.5 ~ 4.0.
Sodium benzoateyog ntsev rau hauv qee cov khoom noj, ntawm chav kawm, tab sis nws kuj tseem tuaj yeem tshwm sim los ntawm cov organic chemical, thiab ntxiv rau cov khoom noj, vim nws cov nyhuv anticorrosive. Thaum siv los ua cov tshuaj tiv thaiv,sodium benzoatefeem ntau ntxiv rau qhov me me, uas yuav ua rau cov khoom noj ntau dua thiab ntau dua vim tias muaj ntau dhau los.Sodium benzoatetuaj yeem pom nyob hauv ntau cov ntawv teev khoom noj vim nws tua tau cov kab mob, cov poov xab, cov pwm, thiab lwm yam, thiab feem ntau pom muaj hauv kev tswj cov khoom noj nrog cov kua qaub lossis alkaline.
Txij li thaumsodium benzoatetsuas yog nyob ntawm nws qhov zoo tshaj plaws thaum PH ntawm cov zaub mov yog tsawg dua 3.6, qhov no yog vim li cas nws yog tub ntxhais muaj nyob rau hauv feem ntau sodium carbonate, vinegar, kua txiv hmab txiv ntoo, thiab cov kua txiv hnav zoo. Nws kuj yog tseem siv los nres dej cawv txiv hmab liab lub sijhawm thaum tag nrho cov txheej txheem. Yog lawm,sodium benzoateyog tshwm sim hauv txiv apples, pears, cranberries thiab lwm yam txiv hmab txiv ntoo tshiab, paj lilac, lub hnub qub anise thiab lwm qhov qab zib me ntsis txuj lom, tab sis kuj nrog me me ntawmsodium benzoateCov. Tab sis covsodium benzoatenyob rau hauv cov zaub mov no tsis yog inherently corrosion resistant.
