EXAMPLE 3 This example illustrates a continuous process according to the invention.The procedure of Example 2 was followed, except that the reaction temperature was 60° C., the reactor residence time was 0.74 hour, and the following flow rates were employed: DMAEA, 13.80 grams/minute; H2O, 4.67 grams/minute; CSTR product, 31.62 grams/minute; DMAEA recycle, 8.28 grams/minute; and AETAC decanter product, 23.33 grams/minute. Methyl chloride was added at high rate until the system pressure reached 240 kilopascals (20 psig), after which time the methyl chloride flow rate was reduced to 4.87 grams/minute (equimolar relative to DMAEA feed). At steady state, the reactor pressure stabilized at 210 kilopascals (16 psig) and the decanter at 115 kilopascals (2 psig). The product was discharged from the decanter to atmospheric pressure without need for degassing dissolved methyl chloride. The acrylic acid level in the resulting product was 0.25%.
