Kev Siv
3-Nitrobenzoic acid tau siv los tshawb nrhiav lub luag haujlwm ntawm ozone ua qhov kev rhuav tshem ntxiv lossis cov tshuaj ua tiav hauv kev rhuav tshem ntawm o-, m- thiab p-nitobenzoic acids.
3-Nitrobenzoic acid yog ib qho nruab nrab ntawm cov khoom siv photosensitive, cov xim ua haujlwm thiab cov tshuaj. Hauv kev lag luam tshuaj, nws yog siv los tsim cov kua qaub bile, acetic acid thiab lwm yam.
m-nitrobenzoic acid yog ib qho reagent siv rau hauv kev sib txuas ntawm allyl acetate rau allylic, aliphatic thiab benzylic alcohols. Nws kuj tseem siv ua chemoattractant tawm tsam Pseudomonas hom.
Ntim thiab Xa Khoom
25KG / Hnab los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
