N,N-Dimethyl-2-propenamide - Introduction
N,N-Dimethylacrylamide is a colorless liquid, molecular formula for C6H11NO, commonly abbreviated as DMADA. The following is an introduction to the nature, use, preparation and safety information of N,N-Dimethylacrylamide:
Nature:
-Appearance: colorless liquid
-Molecular weight: 113.16g/mol
-Melting point:-10 ° C
-Boiling point: 163-164 ° C
-Density: 0.907g/cm³
-Solubility: Soluble in water and some organic solvents
Use:
N,N-Dimethylacrylamide has good solubility and reactivity, and is mostly used for the synthesis and modification of polymers. It has a wide range of applications in the following areas:
-Polymer materials: used as crosslinking agents, anti-impact agents, plasticizers to improve the thermal stability and mechanical properties of polymers.
-Biomedicine: Used as a carrier for drugs and biomolecules to improve their stability and delivery performance.
-Oilfield oil enhancer: used to improve crude oil recovery.
Method:
The preparation of N,N-Dimethylacrylamide is usually achieved by direct acylation of DMF(N,N-dimethylformamide).
1. DMF is reacted with acrylic acid monomer to generate N,N-Dimethylacrylamide.
