Kev siv thiab kev sib txuas ntawm N, N'-Methylenebisacrylamide 99%

N '-methylene diacrylamide yog ib qho amine organic teeb meem, uas yog dav siv los ua tshuaj reagent.Nws yog siv nyob rau hauv zus tau tej cov thickening tus neeg saib xyuas thiab nplaum nyob rau hauv lub textile kev lag luam, thiab nyob rau hauv zus tau tej cov plugging tus neeg saib xyuas nyob rau hauv cov roj exploitation. Nws kuj yog siv dav hauv ntau qhov chaw xws li tawv chemical kev lag luam thiab luam ntawv.Nws yog ib hom crosslinking tus neeg sawv cev nrog ruaj khov zoo, siab purity thiab kev ua tau zoo uas tau siv dav hauv kev lag luam. Nws belongs rau lub thickener thiab nplaum ntawm acrylamide.

N, N '-methylenediacrylamide (methylenediacrylamide) tuaj yeem siv los ua tus neeg sawv cev crosslinking rau kev npaj ntawm polyacrylamide gels, kev sib cais ntawm biomolecular compounds (proteins, peptides, nucleic acids).Nws tau hloov acrylamide, yog li nws muaj qee yam toxicity. me ntsis irritate lub qhov muag, daim tawv nqaij thiab mucous daim nyias nyias thiab cuam tshuam rau lub hauv paus hlab ntsha system.Tsis txhob sib cuag nrog tib neeg lub cev ntev. Tsis txhob nqus cov hmoov. Ntxuav nws nrog dej huv.

Txoj kev npaj Cov khoom tsim muaj ntsig txog kev npaj ntawm NN '-methylene diacrylamide, cov kauj ruam ntawm cov hauv qab no:

(1) Ntxiv 245kg dej rau hauv lub reactor, tig rau ntawm Chemicalbook thiab do, thiab kub txog li 70 ℃;

(2) Tom qab ntawd ntxiv 75kg acrylamide, 105kg formaldehyde, tib lub sij hawm ntxiv polymerization inhibitor p-hydroxyanisole, qhov sib ntxiv ntawm 100 ~ 500ppm, stirred ntawm 40 ℃ rau 1 teev, tag nrho cov tshuaj tiv thaiv;

(3) Tom qab ntawd ntxiv 75kg acrylamide, 45kg catalyst hydrochloric acid, rhuab mus rau 70 ℃ hauv qab nplawm, cov tshuaj tiv thaiv rau 2 teev, txias rau 48 teev;

(4) Cov khoom lim tau qhuav ntawm 80 ℃ kom tau NN '-methylene diacrylamide cov khoom tiav.

Daim ntawv thov

· Siv los ua cov khoom tseem ceeb rau kev sib cais cov amino acids thiab cov khoom tseem ceeb rau cov nylon photosensitive los yog photosensitive plastics;

· Nws tuaj yeem siv los ua dej thaiv tus neeg sawv cev hauv kev ua haujlwm ntawm cov roj av thiab kev ua haujlwm hauv tsev, thiab ua tus neeg sawv cev crosslinking hauv kev sib xyaw ntawm acrylic resins thiab adhesives;

· Siv los ua cov nylon photosensitive thiab photosensitive yas raw cov ntaub ntawv, cov ntaub ntawv hauv tsev, thiab kuj siv rau kev yees duab, luam ntawv, phaj ua, thiab lwm yam .;

· Rau kev sib xyaw nrog acrylamide los npaj polyacrylamide gel rau cov protein thiab nucleic acid electrophoresis.
