English name: MBA; BIS; NAPP; N, N-Methylene Bisacrylamide; BIS-Acrylamide; N, N-Methylene-bis-acrylamide; N, N-Methylenebis (2-propenamide)
Other names: N, N-methylenebisacrylamide; bisacrylamide; N, N-methylenebisacrylamide; methinebisacrylamide; N, N-methylenebisacrylamide
CAS number: 110-26-9
C7H10N2O2 = 154.17
Level: High purity grade
Content: ≥99.0%
pH (1%, 0.1M NaCl) @ 25C:> 5.0
Absorbance (1%, Water): ≤0.2%
Acrylic Acid: ≤0.001%
Conductivity (2%, Water) (umhos): ≤5
DNase (P / F): None
RNase (P / F): No protease Protease (P / F): No traits: White crystalline powder, odorless, extremely hygroscopic. In case of high temperature or strong light, it is self-crosslinking, slightly soluble in water and ethanol. A mixture of acetone dissolved in water and water. At 20 ℃, it is soluble in water at 0.31g / ml, and the aqueous solution can form acrylic acid and ammonia due to hydrolysis. Melting point> 300 ℃. Moderately toxic, LD50 (rat, oral) 390mg / kg. Irritating. This product has certain toxicity due to its substituent acrylamide. Can slightly irritate eyes, skin and mucous membranes. Should avoid direct contact with the human body for a long time. Incorrect application of clean water for cleaning purposes: biochemical research. Separation of biopolymer compounds (proteins, peptides, nucleic acids). Polyacrylamide gel technology and clinical testing. Copolymerization with acrylamide can be made into oil field fracturing fluid, and copolymerization with a certain monomer can be used to prepare insoluble resin, which can be used as water blocking grouting material. It can also be used as a crosslinking agent for preparing polyacrylamide gel. Used in the production of printing and dyeing aids, napkins, diapers for health care, and superabsorbent resins used in other industries. Clinical examination is an important material for separating amino acids. In underground buildings, the insoluble gel formed by AAM and MBA injection into the soil layer strengthens the soil layer to prevent water seepage. Adding concrete can shorten the maintenance of concrete and improve water resistance. In addition, MBA is also widely used in electronics, papermaking, printing plate making, synthetic resin modification, coatings, adhesives, etc .: RT, protected from light
