Description
N-Vinylformamide (NVF) is a class of N-vinylamide that serves as a precursor to amide and amine functional polymers. It is characterized by its high reactivity in polymerization and hydrolysis, making it a valuable compound in various applications.
Uses
Used in Polymer Industry:
N-Vinylformamide is used as a monomer in the free radical polymerization process to form poly(NVF), a polymer with a molecular weight ranging from 104 to 106. This polymer is known for its unique properties, such as high solubility in water and resistance to organic solvents, which make it suitable for various applications.
Used in Chemical Synthesis:
NVF is used as a versatile building block in the synthesis of various functional polymers and copolymers. Its high reactivity allows for the creation of polymers with tailored properties, such as hydrophilicity, biocompatibility, and stimuli-responsiveness, which can be utilized in different industries, including pharmaceuticals, materials science, and environmental technology.
Used in Water Treatment:
NVF-based polymers can be employed in water treatment processes, such as flocculation, coagulation, and adsorption, due to their high water solubility and ability to form complexes with various contaminants. This makes them effective in removing pollutants and improving water quality.
Used in Biomedical Applications:
The biocompatibility and stimuli-responsiveness of NVF-based polymers make them suitable for use in biomedical applications, such as drug delivery systems, tissue engineering scaffolds, and diagnostic tools. These polymers can be designed to respond to specific biological cues or environmental stimuli, enabling controlled release of therapeutic agents or targeted interactions with biological systems.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 13162-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,6 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13162-05:
(7*1)+(6*3)+(5*1)+(4*6)+(3*2)+(2*0)+(1*5)=65
65 % 10 = 5
So 13162-05-5 is a valid CAS Registry Number.

Reactions of ethylidene diacetate: Formation of N-vinylamide precursors ethylidene bisacetamide and ethylidene bisformamide
Rabasco, John J.,Waller, Francis J.
, p. 4953 - 4956 (1997)
Ethylidene diacetate (EDA) reacts with formamide or acetamide under stoichiometric base or catalytic Lewis acid conditions to afford the corresponding ethylidene bisamides and N-vinylamides. Sn(OAc)2 afforded an overall 82.6% selectivity to the desired acetamide derivatives. Sn(OAc)2 and Zn(OAc)2 facilitate amide attack at the tertiary carbon of EDA.
