General Description

1-ethenyl-5-methylpyrrolidin-2-one, also known as N-vinyl-2-pyrrolidone, is a colorless liquid organic compound with a molecular formula C6 H9 NO. It is a versatile monomer that is used in the production of various polymers and copolymers, including polyvinylpyrrolidone (PVP). It is also used as a co-monomer in the production of various copolymers, such as polyvinylpyrrolidone-vinyl acetate copolymers, which are used in various industries including pharmaceuticals, cosmetics, adhesives, and coatings. 1-ethenyl-5-methylpyrrolidin-2-one is also used in the production of cross-linked PVP, which has applications in the pharmaceutical and healthcare industries as a binder, film former, and drug delivery agent. Additionally, N-vinyl-2-pyrrolidone is used as a reactive diluent in radiation-curable coatings and adhesives, and as a co-monomer in the production of specialty copolymers.

Check Digit Verification of cas no

The CAS Registry Mumber 26716-46-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,1 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 26716-46:
(7*2)+(6*6)+(5*7)+(4*1)+(3*6)+(2*4)+(1*6)=121
121 % 10 = 1
So 26716-46-1 is a valid CAS Registry Number.

Efficient palladium catalysis for the upgrading of itaconic and levulinic acid to 2-pyrrolidones followed by their vinylation into value-added monomers

The production of monomers from bio-based platform chemicals shows great potential to reduce the chemical industry's demand for fossil resources. We herein present a two-step approach, which yields N-vinyl-2-pyrrolidone monomers from bio-based carboxylic acids, such as itaconic and levulinic acid. A highly active, heterogeneous palladium catalyst facilitating the reductive amidation of itaconic acid (TOF = 950 molPyr·molPd-surface-1 h-1) as well as the reductive amination of levulinic acid (TOF = 4000 molPyr·molPd-surface-1 h-1) was designed. Especially the reductive amidation of itaconic acid to 3- and 4-methyl-2-pyrrolidone was found to be structure sensitive. A clear trend between Pd particle size and catalyst activity could be shown by the synthesis of Pd/C catalysts with varying Pd particle sizes. The vinylation of the synthesized methyl-2-pyrrolidones with acetylene was tested using common industrial conditions (10-18 bar acetylene, 150 °C, KOH catalyst, no solvent). Similar to the industrial vinylation of 2-pyrrolidone, good yields of up to 80% N-vinyl-methyl-2-pyrrolidone were received. Therefore, and due to the excellent maximum yield of methyl-2-pyrrolidones in reductive amidation (95 mol%), the envisioned process can be a promising drop-in technology, directly replacing fossil resources in the production of an established monomer class.
