摘要：
The present invention provides a method for extractive recovery and conversion of selected compounds, such as methacrylic acid (MAA) and 2-methacrylamide (MAM), from a stream derived from purification of methyl methacrylate (MMA) or methacrylic acid (MAA) produced via a conventional ACH route process.
